Inkjet Clear Polyester for Regular Film Positive Production
Rittagraf Inkjet Clear Polyester is a transparent PET film specifically treated for producing digital film positives with inkjet printers.
This 100-sheet box is intended for workshops, studios, schools and professional users producing positives regularly and requiring a consistent film for everyday production.
One side incorporates a special ink-receptive coating that helps produce sharp images and high-density blacks while maintaining good light transmission through the clear areas.
Specifically Designed for Inkjet Printing
Inkjet inks require a receptive surface to control ink deposition and adhesion.
The coating on Inkjet Clear helps produce fine detail, clean edges and dense printed areas suitable for exposure processes.
The film is coated on one side only, which is the side that must be printed.
Transparency and Optical Density
The transparent areas of a positive should efficiently transmit exposure light, while printed areas need sufficient density to block it.
Both DMin and DMax are therefore useful parameters when evaluating film for photomechanical work.

Maximum density also depends on the printer, ink, print profile, resolution and ink deposit.
Screen Printing Film Positives
Inkjet Clear can produce positives containing solid artwork, text, illustrations, halftones and colour separations.
The 100-sheet format is particularly practical for professional workshops, print studios and educational environments with regular positive production.
Photogravure and Photopolymer
Its good light transmission also makes it suitable for photogravure, photopolymer plates and other photomechanical processes.
Exposure times should always be checked when changing film or printing conditions.
Cyanotype and Alternative Processes
It can also be used to print digital positives or negatives for cyanotype, Van Dyke, SolarFast and other alternative photographic processes.
When Should I Choose the 100-Sheet Box?
This presentation is particularly suitable for:
- Professional screen printing and printmaking workshops
- Art schools and educational centres
- Graphic and print studios
- Shared workshops
- Regular film-positive production
For occasional use, the same film is also available as individual A4 and A3 sheets.
Inkjet Clear, Inkjet Matte or Laser Film?
Inkjet Clear combines a clear base with a coating specifically designed for inkjet printing.
Inkjet Matte is also intended for inkjet printers but has different surface and thickness characteristics.
For laser printers, choose a laser-compatible polyester film specifically designed to receive toner.
Available Formats
Each box contains:
- 100 A4 sheets
- 100 A3 sheets
Inkjet Clear is also available as individual sheets and as a 24" (61 cm) roll for inkjet plotters.
