This 20-sheet pack of 8.5 x 11" Inkpress Transparency Film is a 7 mil thick clear polyester substrate for use in most popular inkjet printers using dye or pigment inks. Its special coating creates a glossy finish and allows a short drying time. The temperature-stable base makes it suitable for a wide range of applications including indoor and outdoor signage, transparency film emulation or window display. Skilled printers can double-print for maximum density. Users can also use this material to create "digital negatives" for oversized contact printing onto darkroom papers.
