Prim Jet Color produces various kinds of lacquers, under the common name Pre Coat, designed for the initial preparation of the media’s surface on which has to be made printout. Sublimation transfer on such media as glass, metal, ceramics, wood without activating their surface is impossible.
Prepares media for printing with solvent ink or UV-cured ink
Lacquer Pre Coat 1 is a universal water-soluble lacquer (primer) designed to enable digital inkjet printing (plotters, printers) on various media. First of all, it is designed to allow direct printing with solvent inks on such specific media as, for example, metal, glass and melamine. In the case of UV-cured ink printing, the adhesion of the ink to the lacquered surface is much higher than to the surface without the initial lacquer layer. The printout better holds the ground and is more resistant to mechanical damage.
Pre Coat 1 can contain additional nano components that increase the resistance to UV radiation.
For sublimation transfer on natural fibers
Lacquer Pre Coat 2 prepares base for sublimation transfer on a cotton and other natural fibers (silk, linen, wool). It is prepared on the basis of water acrylic dispersion. The lacquer is water-soluble and after drying-time becomes waterproof. It creates a thin very elastic/flexible homogeneous, smooth layer on the media.
Lacquer Pre Coat 2, which prepares 100% cotton fabrics and other natural fibers for sublimation transfer, should completely cover the surface designated for printing (lacquer Pre Coat 2 should be accurately placed using, for example, appropriate forms, patterns in the place intended for printing). Usually the surface for sublimation transfer is coated with lacquer Pre Coat 2 using a sieve to serigraphy (this method provides the most uniform layer of lacquer), using a roller for dense acrylic paints or with the help of a compressed air gun.
Correctly coated surface should dry out. The drying process can be accelerated by curing the coated fabric using, for example, a hot air source or a press. We suggest carrying out own tests on how thick the lacquer Pre Coat 2 layer should be for the sublimation transfer to be optimal. Too thinly covered surface for printing causes that colors after sublimation are not sufficiently intense, while too thick layer of varnish stiffens the fabric and causes blurring of printouts (diffusion).
Too thin lacquer layer causes that colors after sublimation are not sufficiently intense, while too thick lacquer layer stiffens the fabric and causes blurring of the printout contours (diffusion).
It is necessary to wash the finished sublimation printing to make it flexible. After the sublimation transfer, the printout is permanent. However, the total polymerization process takes about 24 hours and after this time the durability of the printout is the highest.
In order to obtain very intensive colors and even greater durability of the printout, before the sublimation transfer, it is necessary to additionally to heat the Pre Coat 2 lacquered fabric (after drying) for 2 minutes at 160°C. The best results are obtained when the lacquer is applied by means of a sieve on a dense fabric.
For sublimation transfer on various (hard) media
Lacquer that allows sublimation on stiff (hard) media (e.g. ceramics, glass, metal, hard wood, plastics, thick paper, cardboard) is lacquer Pre Coat 5.
The lacquer is a one-component water system, it does not require heating, it is an autocatalytic mixture. It does not contain harmful or toxic substances, and does not generate waste that requires disposal. Printouts made with this lacquer can be washed with household cleaners.
The lacquer can be applied with a brush, roller, by soaking (non-absorbent elements), spraying or tampon.
Sublimation transfer can be performed after the substrate has dried in the temperature from 190ºC to 210ºC.
The lacquer is available in two versions: colorless, it retains the appearance of the substrate on which the transfer is carried out, or white, opaque, which allows you to apply prints to items of different colors. White lacquer allows you to bring out the full color depth.
