This clear, 5 mil polyester Film was specifically designed for making Film positives or negatives for use in the prepress phase of screen printing or offset printing. The clear, microporous coating on this dimensionally stable Film produces accurate dot placement and high Dmax and low Dmin values with minimal yellowing of the Film. Sihl 3642 Spirit II screen positive Film works well with popular Canon imagePROGRAF, HP DesignJet, and Epson Stylus Pro and Pro photo printers that use aqueous pigment inks. It can also be used with aqueous dye inks.
