Flexo Graphic Inks
Printing inks - Flexo printing
Flexographic printing processes belong to the category of Relief printing processes. Embossed printing parts are being used in order to transfer the ink from a printing ink cylinder towards a substrate. Substrates can be paper but in most cases we are talking about polymer films.
Characteristic is the low viscosity of the inks and the low pigment level that is being used. Normally no rheological modifiers are being used in order to adjust the viscosity. This printing process is being used for packaging and bags. Advantage is a very high printing speed, disadvantage the limited quality.
Especially for high performance packaging inks Matting agents are being used in order to differentiate the print (e.g. cosmetic packages)
