A top coated clear transparent film for the production of reprographic masters in the pre-printing stage to expose silk-screens, flexoplates and other light-curing copying systems. The film meets the highest demands with regard to dimensional stability, flatness and UV density even with high ink loads.
HP/RS is a version with removable white plastic strips for Hewlett Packard plotters equipped with optical sensors.

Characteristic |
Suitable for Thermal Ink Jet printer Suitable for Piezo Ink Jet printer Suitable for pigment inks which offers improved light stability Suitable for Dye Ink Removable stripe for sensor detection Improved water resistance Fast Ink Drying High Ink Absorption Dot reproduction = up to 48 L/cm for screen printing application (depending on the combination system, higher screen rulings are possible) Coated on reverse side for good slip properties and fast vacuum in the exposure unit frame High density range:
DmaxUV: 3.2 up to > 4 (depending on RIP settings, ink system and measured spectral characteristics of the densitometer)
Dmin UV: approx. 0.06 to 0.12 (depending on the measurement characteristics of the densitometer).

Compatibility |
Suitable for most large format Ink Jet printers using waterbased dye or pigment inks Not compatible with oil and solvent based systems. Prerequisite for a high ink coverag (copy density) are printers, which allow settings for high resolution and high ink loads. These various settings are often not available with the usual driver settings and can often be made for screen use only in combination with special RIP tools.
Due to this reason, desktop printers (A4, A3) also often do not offer the desired coverage. Dependant on ink type dye ink can produce a migrating yellowing effect.

Handling |
Optimal between 15-30°C and 40-60% r.h. A preconditioning period of 24 hours within the printing environment is recommended.
Avoid fingerprints on printing side. When exposing certain types of emulsions and polymer plate layers (flexo) the film can sometimes have a tendency to stick to the image areas. This effect can be reduced by set off "pre-powdering" (Talcum) of the film and emulsion. A very thin and transparent PET-film can also be used but be aware of undercut issues. The copy density should register with a UV-Densitometer (p.ex. X-Rite 369) to a value >3. Densitometers with a measurement range in the visible light spectrum (measurement filters DVIS) can lead to inaccurate results. For demanding halftone and separation work, we recommend special RIP-Software tools such as COLORGATE-Filmgate, WASATCH, PERFECTPROOF etc in combination with LF printers like EPSON Stylus pro (Ultrachrome Photoblack/K3-inks), HP Z-series & CANON iPF-series. For optimisation of halftones a linearization of the printer setting is essential Further information for handling is available in the separate document "Handling Guide" contained in our "internet downloads" section. Due to the high ink absorption of the film coating the surface is strongly hydrophilic and can therefore in high humidity or very dry climates have a tendency to curl. Installing temporary air-drying heaters or humidifiers near the printer may reduce or elimate this issue.
