Ultrafine ULTRASCREEN film is a high density polyester-based clear film for computer-to-film digital imaging using recommended inkjet printers. It is ideal for pleasing full-colour & screen positives in any size, with unbeatable value-for-money. ULTRASCREEN film is designed to produce high-resolution four-color plate-ready positives, with UV density matching silver-based films. ULTRASCREEN can also be used for generating negatives. However, the ink consumption is significantly higher than that for making positives. When imaged on high-resolution pigment-based inkjet printers (e.g. Epson Stylus Pro series), the patented ink-receiving layer ensures excellent reproduction of 2 - 98% dots at 2880 dpi, micro-fine lines and perfect solids. ULTRASCREEN offers the lowest cost computer-to-film solution, ideally suited for newspapers, book & magazine publishers, screen printers and several other applications currently using expensive silver-based films.Ultrafine Waterproof (Ultrascreen) film from Photo Warehouse is based on the same standards as the popular FastPOSITIVE - which was the industry standard.
