The characteristics of the new polyester inkjet ink, no VOC design

1。 The VOC (Volatile Organic Compounds) design reduces the amount of VOCs emitted during printing, improving the printing work environment and reducing the burden on the global environment.
2。 The “pigment nanodispersion technology” (the technology for dispersing and stabilizing nano-size pigments) is used by Flower King’s proprietary “pigment nano-dispersion technology”.
3。 Ultraviolet-cured inks in order to achieve excellent image durability, such as weather resistance, alcohol resistance, scratch resistance, etc., do not require external coating treatment.
4。 It can be developed for a variety of industrial printing applications, such as film printing and signage.

For water-based inkjet ink technology pigments, (using electrostatic phenomenon) fusion in electronic photographic printing for powder tomography in the polyester resin technology, the non-reactive and non-hazardous material water however, ink, equivalent to weathering, alcohol-resistant new UV-cured ink, can provide high durability images such as scratch resistance, polyester inkjet ink pigments, so that a variety of industrial printing deployment of successful development.

Typically, UV-cured inks are printed on, for example, paper or film, and have substrates that are cured by irradiation of UV rays to form a firm coating of about 10 microns. In contrast, in this new polyester-based water-based ink, newly developed polyester resin forms a uniform and solid coating.

Although the film thickness is approximately 1/10 of the UV-cured ink, the coating achieves image durability comparable to that of UV-cured inks. This allows for a wider range of applications, such as film printing and industrial printing for signage.

Sell large format printers on a pay-per-use basis

South Africa-based Midcomp has launched an innovative pay-per-use (PPU) program for HP Latex 300 and 500 printers.

Common in the copier market, this proven concept has now been introduced into the large format industry, charging customers a “print-per-print” price that includes the cost of ink, maintenance, service and any printer repair.

Midcomp, a 28-year-old supplier of printing and reprocessing equipment and consumables, has found a gap in the market where customers can now purchase HP Latex printers and then charge a customized per square metre price based on estimated usage. This scalable model makes it a viable solution for a printing company of any size.

“Everyone in the printing plant is too familiar with unexpected and expensive repairs. About 18 months ago, we began to study the difficulty of implementing PPU models in the large format printing industry. Prior to the launch, we had installed more than 50 machines in the testing phase alone, so the demand was clear,” said Rob Makinson, chief executive of Midcomp Group.

It is conceivable that this pricing model is the most attractive for new users, but Midcomp has received higher acceptance from existing printer users because they have learned about unforeseen repair costs and the ease with which they underestimate the offer. Print the job. While maintenance contracts can solve many of these problems, they do not include expendable items and are fixed monthly costs regardless of usage and ROI.

Fixed costs per square metre eliminate any guesses in the quote, increase profitability and reduce management time. PPU includes ink, print head, maintenance cartridges, service phones, labor, spare parts and maintenance kits that save you great effort and minimize downtime.

Support doesn’t stop there. Midcomp also provides its customers with access to its innovation center (iHub), a 260-square-meter plant offering a variety of printing and painting solutions. PPU participants can avoid production downtime and gain limited overcapacity support, and explore potential growth areas through this unique hub.

In addition to service elements and iHub’s reliability and reduced risk, PPU customers can benefit from shipping inks and printheads on the shelves, eliminating the risk of emergency delivery needs or delays without incurring up-front costs.

HP was introduced because of the availability of reliable data. To date, both series have benefited from transparent information passed from embedded Web servers to THE HP application “Latex Mobile”. Over time, Midcomp expects HP to have data for a broader portfolio, allowing it to expand the PPU scenario.

Earlier, at the PackExpo show in Las Vegas in September, Kirk-Rudy showed off a FireJet 4C single-paper four-color inkjet system with a DuraFlex inkjet printhead.

The machine is an A3 wide-format single-pass printing system that can print at 1600 x 1600 dpi speeds, with a maximum speed of 150 feet per minute.

It uses pigment water-based inks designed to print envelopes, bags, packaging, napkins and other items cost-effectively.

Understanding screen printing inks

Screen printing caters for a very wide range of applications, from graphics to textiles and industrial uses, and this is reflected in the choice of inks available.

This includes solvent and water-based inks as well as LED UV-curing inks. Some of these are better suited than others to particular substrates and applications.

One of the great advantages of screen printing is that you can adjust the ink to suit your requirements. As a general rule, most solvent inks are not ready to use and require thinners or retarders to be added. UV inks are generally ready to use from the tin but you might still mix in further additives for special requirements, such as an anti-slip surface or a resistance to sticky tape or a hardener for a tougher finish or even just to work with finer mesh.

When it comes to display and graphics applications, most printers appear to be predominantly using UV curable inks. However, UV curing requires a bigger investment in drying systems so many smaller companies may stick with their existing solvent screen print set-up, and some of these may also have moved more into industrial markets. But UV curing is more attractive to the larger players because it offers a smaller footprint, faster throughput and easier control of the process.

That said, solvent-based inks still have an edge in dealing with difficult substrates and can also offer greater opacity. Solvent-based inks are still widely used in the industrial markets, mainly because there may be particular performance requirements.

Robin McMillan, marketing manager for Sun Chemical, explains: “In graphics the ink is usually chosen just for its graphic qualities. But in the industrial space there may be more functional reasons such as resistance to whatever’s in a plastic container, like bleach.”

But for general graphics work, the UV inks seem to win out.

James Whitehead, wide format marketing manager for Fujifilm Speciality Ink Systems, points out that solvent inks used on a flatbed screen with a wide area will lead to a significant amount of the ink volume evaporating off as the ink dries. He adds: “The other issue with an evaporative process is that there will be a tendency for the ink to try and dry whilst it’s still in the screen.”

So, not surprisingly, Fujifilm only offers UV inks. Whitehead says: “UV helps you to print with finer mesh screens and finer detail and it’s more cost effective.” Whitehead says that screen print inks can give very vibrant colours, noting: “I think that for pure Pantone colours then a colour matched ink is still going to give you a better result then a digital system will.”

Dave Duffy, technical services representative for Nazdar in Europe, says that Nazdar has seen some interest in its water-based inks, mainly because they are seen as being more environmentally-friendly. Water-based inks can be more difficult to work with as the ink is prone to evaporating off. Nazdar sells the 2700 Series for use with paper board, vinyl type applications.

Duffy notes that it’s relatively easy to switch from solvent to water-based inks because they use the same dryers. Switching to UV inks on the other hand requires an investment in UV dryers and a different mindset in handling the inks.

LED curing

Duffy also says that one of the major trends now is for LED UV curing. There are a number of advantages to LED curing. Firstly, there’s very little heat so no need for cooling, which can be useful for some substrates such as polycarbonates. Also the lamps last considerably longer – 10-30,000 hours as opposed to 1,000 to 1500 hours with a mercury vapour lamp. But the inks are more expensive and the technology is only in its infancy.

However, McMillan says that although there is a lot of talk about LED UV curing, there are not many installations in the graphics sector. He says: “They tend to be fairly wide and could be over two metres so the economics don’t stack up as well as for industrial uses that might use a narrower format.”


As we’ve noted, there’s a wide range of substrates that can be printed via screen printing, which means that most ink vendors tend to carry a wide range of different inks to cope with types of material.

However, the reclassification of some chemicals under the REACH initiative – and in particular NVC – has led many ink vendors to have to reformulate their inks. Thus Fujifilm, for example, has developed a multi-purpose ink, UVXtra VW, which is available in both a gloss and satin finish. It’s suitable for a range of materials from PVC to Correx boards. Whitehead explains: “Historically we would have had three or four different inks for these materials but now we have just the two, which has advantages in carrying lower stock inventory.”

Screen v digital

The wide format graphics market has been under a sustained assault from digital printing and this is one reason why many ink manufacturers do look to the industrial market requirements. But McMillan says that digital printing is having less effect now: “Ten years ago there were significant inroads in screen printing because of digital but I would say that has largely levelled off today.” Instead he says that most of the large service providers have a mix of technology, including screen printing.

He points out that screen print inks have a much longer outdoor life span, with no need to laminate them and also says that screen printing inks can be mixed for additional requirements such as resistance to solvent cleaning products. He adds: “The other advantage of screen is its ability to print spot colours accurately. You can have metallics and fluorescents and also opaque whites are much easier. So you can get much more accurate Pantone matches.”

But he also says that it’s not a case of one technology displacing another as many printers will use screen to add an opaque white backing to a digital backlit print or a large area of a solid tint, because the colours are better or more opaque, or simply cheaper to use.

ICC Color Management: Take you to have an all-round view of ICC

What is icc profile?
In color management, an ICC profile is a set of data that characterizes a color input or output device, or a color space, according to standards promulgated by the International Color Consortium (ICC). Profiles describe the color attributes of a particular device or viewing requirement by defining a mapping between the device source or target color space and a profile connection space (PCS). This PCS is either CIELAB (L*a*b*) or CIEXYZ. Mappings may be specified using tables, to which interpolation is applied, or through a series of parameters for transformations.

Every device that captures or displays color can be profiled. Some manufacturers provide profiles for their products, and there are several products[1] that allow an end-user to generate his or her own color profiles, typically through the use of a tristimulus colorimeter or preferably a spectrophotometer.

The ICC defines the format precisely but does not define algorithms or processing details. This means there is room for variation between different applications and systems that work with ICC profiles. Since late 2010, the current version of the specification is 4.3

To see how this works in practice, suppose we have a particular RGB and CMYK color space, and want to convert from this RGB to that CMYK. The first step is to obtain the two ICC profiles concerned. To perform the conversion, each RGB triplet is first converted to the Profile connection space (PCS) using the RGB profile. If necessary the PCS is converted between CIELAB and CIEXYZ, a well defined transformation. Then the PCS is converted to the four values of C,M,Y,K required using the second profile.

So a profile is essentially a mapping from a color space to the PCS, and from the PCS to the color space. The profile might do this using tables of color values to be interpolated (separate tables will be needed for the conversion in each direction), or using a series of mathematical formulae.

A profile might define several mappings, according to rendering intent. These mappings allow a choice between closest possible color matching, and remapping the entire color range to allow for different gamuts.

The reference illuminant of the Profile connection space (PCS) is a 16-bit fractional approximation of D50;[3] its white point is XYZ=(0.9642, 1.000, 0.8249). Different source/destination white points are adapted using the Bradford transform.

Another kind of profile is the device link profile. Instead of mapping between a device color space and a PCS, it maps between two specific device spaces. While this is less flexible, it allows for a more accurate or purposeful conversion of color between devices. For example, a conversion between two CMYK devices could ensure that colors using only black ink convert to target colors using only black ink.

The advantage of using ICC
Before advent of the ICC file, If you want to create an import and out equipment file to use the color management system to start a color program, you must follow the manufactory provision.Although it have a great effect in this way, But also have endless works for color correction of different import and out equipments .If you use the X, Y, Z coordinates of color as the reference standard,although you can reach the DIG (DeviceIndependentColor) purposes, but because there is no uniform format,you can not be applied in different color devices.

How to print 3D effect with a UV flatbed printer

The original photopolymer UV inks cured so quickly that they didn’t have time to spread out and form a thin film, so the image areas stood proud of the media. Coarser halftones looked and felt like sandpaper.

Over the years the ink formulations have been refined and techniques such as pinning have reduced this effect to the point that the smarter curing systems can be used to vary the smoothness level between high gloss and matt within the same image.

However, those sandpaper images can be a definite advantage if you exaggerate them. Because UV ink can be cured instantly after printing, it’s relatively easy to print on the same spot to build up layer on layer, giving a raised image that’s obvious to both the eye and to the fingers.

“The raised nature of a UV print – be it clear or process – has allowed tactile signage, or packaging proofs that require a Braille element or any decorative 3D effect to be created by simply printing multiple layers of ink in register,”said Duncan Jefferies, marketing manager for Mimaki’s UK agent Hybrid Services.

Rather like metallic effects, this raised imaging adds perceived value to the print, as the embossed appearance is associated with quality. As we also pointed out, combining metallics with raised ink simulates foil blocking, again a high value effect.

“Raised imaging gives a new effect,”pointed out Nick Decock, commercial marketing manager of Mutoh Europe in Ostend. “The luxury finish is certainly something printers are looking for, as it lets them charge a lot more than for regular work like posters and banners. It can be used for special effects, trophies, prototype packs and cartons – there are lots of possibilities.”

In theory any UV inkjet with a scanning head can do this, providing the Rip and controller are built that way. However, Roland DG was the first to make a big marketing point with this ability in 2008, when it introduced its first VersaUV printer-cutter, the 30 inch roll-fed LEC-300. This was replaced by the faster LEC-330 and the even faster and wider 54 inch LEC-540. It can build up layers of clear ink to form a pattern embossed effect, or it can create textures by using a greyscale image in the artwork file, where dark is “low (ie fewer layers) and white is high (more layers).

The raised layers are set up and controlled by the Rip, in this case Roland’s own VersaRIP which is bundled with all of its printers. Setting up is similar to creating a cutting path for the printer-cutters – a specially named layer is created in the original image file (which is most likely a PDF), which is then detected by the Rip and assigned to the clear ink.

BrotherJet shows off different texture effects using black UV cured ink

According to Jefferies, BrotherJet has been able to produced raised images singe the mid-2000s, although it has never made such a big thing of it as Roland did in 2008. The process is exactly the same as Roland’s building up multiple layers of ink by curing each layer.

The BrotherJet ArtisRIP software enables up to nine layers to be printed automatically to create the raised effect. It claims this requires minimal operator intervention or indeed file setup. By using a greyscale ‘height map’ for the clear layers, variable textures and domed effects can be created. BrotherJet’s UV printers range from the small BR-U1800 and U4880 flatbed models, to the big BR-7880 and BR-9880 flatbeds. these are the new small A3 flatbed BR-U1800 printer.

Mimaki produced this sample of Braille on signage, building up multiple layers of black UV-cured ink

This idea has sometimes been extended into the creative sphere, with raised imaging used for illustrations in Braille books as well as museum and gallery signage and descriptive labels. Using a digital print technology makes this possible for one-offs, temporary signage or short runs at low cost, compared to using metal dies to emboss the images.

Although most people will think of print as a planographic process, meaning its images are flat, metal dies have been used for centuries to add a 3D element to the surface.

Digital printing can now emulate that in ways that would be technically impossible, or too expensive for traditional dies, with the added benefit that there are almost no preparation costs, no special presses, and every copy can be different. The creative potential of raised print is on the up and up.

How does Direct to Garment Printing Work

Direct to garment printing, also known as DTG printing, digital direct to garment printing, digital apparel printing, and inkjet to garment printing, is a process of printing on textiles and garments using specialized or modified inkjet technology. The two key requirements of a DTG printer are a transport mechanism for the garment and specialty inks (inkjet textile inks) that are applied to the textile directly and are absorbed by the fibers.

Brotherjet Direct to garmant printers can printed on any garment t-shirts, caps, siws shirt, Sweatshirt, Fashion collection, Paradigm Shirt, Personalized footwear, Jeans, Non-woven bags and more.

The Brotherjet Dtg printers used water based garment inks who are 100% non-hazardous, toxin-free and adhere to the strictest human health and environmental standards. and have excellent color fastness, high elasticity and non-cracking attributes. Britherjet Dtg printer much convenience for printing, garment loading, and easy ink system maintenance. With 8 ink channels of CMYK+WWWW, it’s good at white ink printing, and can directly print delicate pictures on all colors of t-shirts. The brotherjet new dtg white Rip software support the White and color inks outputs simultaneously in one pass.

This versatile printing process can be used for both textiles and non-textiles. When applied to non-textiles a pre-treatment must be added to the product before the printing, as this allows the ink to correctly attach itself to the substrate. Next is the printing process, which is much cheaper than sublimation. The last step is the curing of the ink, which can be expedited by adding a special aerosol. This will give the product the protective finish.

DTG was primarily designed to work with textiles, to embellish them. It is largely replacing traditional printing because ink costs are low, it’s versatile, and the printing process itself is straightforward.

Enhancing the Ink

Direct to garment printing is a new technology, and like all new technologies, it has its flaws. The biggest challenge in the past has been with the quality of the ink. Fortunately, improvements in ink chemistry are allowing this problem to be overcome. A number of contemporary printer brands are about to reveal some upgrades to the traditional DTG, and there will be enhancements in a number of areas, including automated pre-treatment, palette sizes and ink quality.

A new generation of white inks will be introduced which are performing at much higher levels than older formulations. One of the biggest challenges for direct to garment printing technology has been printing brightly coloured images on darker apparel. The problem is that colours often pop off the darker shirt when the underbase is laid down by the printer. Printing bright images on a dark shirt requires the apparel to be pre-treated, a chemical to be added and then a heat press must be applied, after which a layer of white is added. Printers continue to make improvements to both the DTG ink and the printing process itself.

Catsun graphics opens direct to t-shirt print centre

In a step ahead in promoting digital technologies for textile printing, Catsun graphics has opened a demo centre in Dubai, targeted at garment exporters and decorators, in order to showcase direct to t-shirt printing technologies.

The facility, which is equipped with Brotherjet direct to garment printing machine, GCC plotters, Chemica heat transfer medias and Sefa heat presses, aims to educate and inspire customers, including brands, agencies and print buyers about new approaches to digital print for textiles, said NAJIM, managing director of Catsun graphics

He said, “The centre will enable us to demonstrate latest printing technologies for textiles to existing and prospective customers. The customers can bring their samples and get it tested and printed at the demo center.”

How to Utilize T-shirt Printer  for Printing?
One variation of the heat press obliges a heat exchange or something to that affect, which is stacked into one 50% of the press. The fabric to be printed on is then stacked into the other a large portion of the press. The exchange is then held set up on the fabric by the weight of the press, which seals the heat touchy ink to the filaments. The direct to T-shirt Printer  various bits of fabric or pieces of clothing, utilizing a solitary heat exchange. The mechanical heat press runs the fabric under the platen the obliged number of times until all the exchanges are finished.

For Various Kinds of Needs
Heat press printing is ordinarily utilized within the making of shirts, logo articles of clothing and promoting pennants. It is sensibly practical and can deliver a high volume of printed things amid a solitary session. Heat exchange printing of the kind alluded to above, however, makes a much bigger potential volume of waste than sublimation printing utilizing a computerized printer, as it obliges the exchange themselves to be made, which get to be rejected once an occupation is finished. The sublimation printer has no such run-off along these lines is normally seen as all the more earth inviting.

This dtg printer is likewise utilized within the second piece of the sublimation printing procedure. For this situation, the heat is utilized to seal the colour inside the fabric – after it has been infused by the sublimation printer. The heat press guarantees that the ink, which has been implanted into the filaments of the fabric being printed, is steady and won’t run when the article of clothing or thing is washed. With a scope of sizes and configurations, there’s a heat press machine suitable for each size and style of printing business. The mollusc otherwise called swing press is regularly utilized for T-shirt Printer  shirts or for doing vinyl lettering. Bigger presses with a flatbed setup are utilized for greater occupations – normally sportswear and bigger vinyl lettering applications.

Schedule machines are utilized to perform huge volume sublimation printing and are suitable for each kind of sublimation application. The schedule machine is intended to encourage different prints, rapidly and successfully, and utilizes a drum to guarantee a nonstop moving on and off of the fabric to be printed. With a width that might be to the extent that three and a half meters, the schedule T-shirt Printer  is suitable for standards and banners and apparel, sportswear and vinyl lettering among numerous different applications. Mass sublimation printing wrapped up a machine fills in as typical, by putting away the print occupations in documents that could be rung at whatever point needed.

Flatbed printing with UV curable white ink

Flatbed printing is the term used for digital printers that image directly to a large variety of substrates using UV curable ink. Materials are placed on a vacuum bed and imaged from above. UV curable ink is very versatile and cures by a chemical process when exposed to UV light. Flatbed printing offers stunning resolution and UV resistance for non-fade longevity. This technology allows us to print directly to standard substrates up to 25mm thick, such as Corflute, foam PVC, polystyrene, cardboard and paper in quantities from one unit to hundreds with competitive pricing.

Printing with white ink produces vibrant prints onto dark substrates. By laying down a white layer of the elements in your logo, text or image underneath the colour, you get the full vibrancy of the colours unaffected by the substrate. Alternatively, we can back up the elements with white for reverse applications such as glass.

baby iron  plywood

A machine configured with white ink can print onto a range of substrates unacheivable with standard printing systems. If you have a coloured paper or substrate and do not print a base layer of white, the colour of the substrate will show through. On a black surface the image would be near invisible. On clear sufaces the image would look transparent. We eliminate these issues using white ink.

White is set to print over the entire substrate before the image is printed. Areas with no image will be white and not show the original substrate colour.

White is set to print over the entire substrate after the image is printed in reverse. This is done on transparent substrates so the image can be viewed from the other side, through the substrate. Areas with no image will appear white.

Layer Masks
White is set to print either underlayer or overprint. Any areas can be masked out so the original substrate shows through. Images can also be masked so no white prints on or under them for effect.


Transparency Effects
White can be set to print at various densities. We can control exactly how the white is placed. It can be placed as a solid percentage like 20% (similar to 80% black on a white substrate) allowing the substrate to show through it. We can also print it as a gradient from one percentage to another, like on photographic images controlling what areas get white ink.
White Only

White can be used on its own without the coloured inks at all. If you have a dark substrate we can print a greyscale image using white ink instead of black. Logos can be imaged onto dark or textured surfaces.

The samples to the left show how the different layers are printed in order of colour vs white ink, on the right is how the finished product will look.
