Our Ulano Inkjet Films are available in boxes containing 100 sheets and sizes ranging from 8.5" x 11" to 17" x 22". Pigment Inkjet Film: Inkjet printers can be used as a replacement for a high priced imagesetters. To make positives with an inkjet printer, you must have an absorbent coating on clear inkjet film. The nanoporous 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 are water based and still need time to 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 keep the pigments in suspension retard drying and prevent nozzle blockage need to evaporate the same way stencil coatings need to dry.
