PRIMERS, LIQUID LAMINATES and INK for PRINTERS and PLOTTERS
SUBLIMATION TRANSFER IN FROM PRIM JET COLOR
Modern digital printing market, a rapidly growing for years, requires
from companies producing inks a flexible response to customer needs in the field
of computer-aided publishing work, graphic design, professional activity using printers
and plotters. In response to this demand, the company Prim Jet Color has developed in 1996 recipes
of dye water-based sublimation inks, which the indisputable
advantage is the absence of harmful effects on the environment. These inks
are high quality products, the properties of which should be more widely
presented due to the expected benefits arising from their use.
Dye Sublimation ink is designed to use it in a wide format printers and
desktop printers with piezo print head such as Epson, Mimaki, Roland, Mutoh.
This ink is a product of very high quality with excellent physical and
chemical properties. The components used in the production of ink, coming
exclusively from EU, are high
quality and purity. That is, the ink contains carefully selected dyes, solvents,
surfactants, wetting agents, solubilizing agents, dispersants, humectants,
viscosity modifiers, pH buffers, chelating agents, filters UV,
anti-oxidants and free radicals inhibitors.
The ink can be used in any kind of the plotters and printers without causing damage to the printing system - does not cause corrosion or clogging of the print heads. Does not contaminate the filter and does not damage the electronics of the printing system. It is environmentally friendly and meets the standards of the European Union.
Ink is primarily designed for sublimation on polyester fabrics used for sewing sportswear as well as for the sublimation of the various plastics used in the production of, for example, skis, snowboards, skateboards, surfboards. Graphics, which we want to transfer to a suitable substrate is first digitally printed on paper for sublimation and soaked with the press for sublimation at a temperature of about 210 įC for polyester fabrics or mixed synthetic fabrics containing at least 60% polyester. Temperature and transfer time depend on the sublimation transfer physico-chemical properties of plastic media on which is transferred appropriate image. For example, in the case of skis or skateboards transfer temperature is respectively 170 - 180įC, and the transfer time from 90 to 120 seconds.
Prim Jet Color expanded developed in 1996 recipes of water-based dye sublimation inks to include new colors that are currently used in the latest models of Epson printers. Inks are now available in 10 colors, and the intensity of each color can be increased upon request.
The ink quality even though the cost of ink is only about 25% of the total costs associated with the sublimation transfer on the appropriate media, has a significant impact on the cost of the whole process of sublimation. Loss of material and the ink remaining on transfer paper, and downtime associated with clogging of the print heads significantly increase costs, when you select the wrong ink.
The proper concentration of the dye molecules in the sublimation ink provides excellent coverage of printout with less ink.
Adequate ink drying speed eliminates spots and blots of ink and paper or media wrinkling. Ink rheology is adjusted to the speed of modern printing plotters.
Despite several advantages the sublimation transfer has several important limitations:
If we want to make sublimation transfer on untypical media, we must first properly prepare (activate) them, for example with lacquer Pre Coat dedicated to the specific kind of substrate (PVC, ceramics, metal, etc.) from Prim Jet Color. The lacquer can be applied to the surface using paint gun (recommended option) or roller for acrylic paint. The lacquer fully polymerize within 24 hours and after that time we can start to make sublimation transfer.
SUBLIMATION INK - SUMMARY OF BENEFITS
On the basis of professional experience, the advantages of sublimation ink in comparison with other inks are as follows:
Advantages of sublimation inks over other inks, makes the work with them to be an interesting experience. Possibility of novel applications and a printing cost savings should increase their attractiveness.
Sampler printouts made on ceramic tiles after coating with lacquer Pre Coat 4.
Sample printouts made on hard media (ceramics, glass) after coating with lacquer Pre Coat 4.
Lacquer, which allows sublimation of the rigid media (eg. ceramics, glass, metal, wood, hard plastic, etc.) and paper and cardboard is lacquer Pre Coat 4.
Lacquer Pre Coat 4 is a Polish product designed in 2006 by the founder of Prim Jet Color MPC Christian Airaut, in collaboration with MBA MSc. Jolanta Airaut and D. Sc. Ph. D. Leszek Kułak from Gdansk University of Technology. The lacquer is made exclusively from components from renowned European manufacturers.
Lacquer Pre Coat 4 was designed on the basis of an aqueous dispersion of polymeric resin. The mixture of lacquer and hardener, added in sufficient quantity, is liquid during curing conditions. Then take place chemical reactions leading to a cross-linked polymer solid - the cured lacquer (coating). In order to adjust properties of lacquer to specific customer needs, we can add to the lacquer, for example, the powder fillers, elasticators, thinners or curing accelerators.
Lacquer Pre Coat 4 is waterborne, and after the curing and cross-linking becomes waterproof. It creates a very thin, transparent, uniform and smooth polymer layer on the surface allowing the sublimation transfer.
The addition of the appropriate color pigments to Lacquer Pre Coat 4 gives the desired color of the coated surface. A typical example is the white Lacquer Pre Coat 4 used for sublimation transfer containing white elements (there is no white sublimation ink).
Lightfastness UV tests were performed using Spectroline Lamp ENF-260 C, with wavelength: λ= 254 nm. The results for the different ink colors are presented below:
