Allof us know pigmented inks is often used for digital printing of vinyl and decals and similar substrates due to their color fastness. They are more expensive than dyes, and have less of a color spectrum than dyes do.What's more,pigmented inks are typically weaker, as stated above, but dye inks will tend to run. However, over the past couple of decades, with the advances in digital printing technology, chemists improved dye inks by adding "hot" solvents which evaporate more rapidly, allowing dye to become the base of digital printing inks rather than pigment inks.
Most digital printers also use a heated platen, before, during, and/or after the printing process, as well as fans to aid quick drying and evaporation of the dye inks. Specially treated materials are also used that are "charged" opposite the dye inks which helps them cure more quickly.The dye sub print process utilizes a 4-color printing process similar to an inkjet printer, except instead of using a CMYK (cyan magenta yellow black) color build, it uses CMYO, exactly the same except for the overprint clear.
