PIGMENT INKJET FILM

The newest printers use pigment ink instead of dye ink because it resists fading for up to 99 years. This improves family snapshots, but doesn't help the making of UV opaque positives. The nano porous structure of the coating controls the ink spread for image sharpness. Pigment ink particles are coated with a resin so they can be controlled with piezo print heads.

Modern inkjet inks used for positives are water based and still need time to evaporate and dry. Ink manufacturers need to balance nozzle maintenance and the desire to have an ink that dries fast after printing, so a positive can be used to make a screen. Glycol or glycerol humectant additives in the water based carrier that are used to to keep the pigments in suspension, retard drying, and prevent nozzle blockage need to evaporate the same way stencil coatings need to dry.

Pigment Inkjet films are coated on 5 mil polyester. The coating loves water which is the carrier for the ink. The polyester side is very shiny and doesn't absorb water. You can test the film for the coated side by wetting your fingers and pinching the film on both sides. The coated side will get sticky just like capillary film. Rolls are coiled with the coated side out, ready to go into the printer.
