There are various types of ink, which differ in the chemical composition and physical and for additives used that vary strongly the main features, such as: surface tension, density, evaporating temperatures, etc. All of these parameters affect the very possibility of the ink to be used effectively in inkjet printers and the result of the press itself.
Mainly can be divided into 4 types of ink:
Dye-based
And ‘the ink longer used, the first being developed for inkjet prints. This is a solution in which the dye molecules are dissolved in the liquid solvent, generally water. Its chemical composition makes it easy to use on most inkjet printers so far marketed.
Pigment ink
To overcome some of the major flaws dye-based ink, in particular the lack of time, many manufacturers have developed pigment ink. Pigments in the ink to the colorant is composed of small particles in suspension in the liquid.
UV ink
The UV ink is a type of ink that, alongside those in solvent and water-based.
This type of ink is fixed on the support thanks drying generated by two UV lamps. They in fact, thanks to the emission of UV rays, the ink transforms from liquid to solid aggrappandolo on the surface of the print media. The drying process is very fast and does not need any drying time. The colors are perfect and a unique brilliance.
