Idealine RPF is a red-sensitive line film. It is especially designed
for ultra-short exposure times in photoplotters with red neon lasers
(633nm) or laser diodes (650 – 670 nm). Idealine OPF is a green-blue-
sensitive line film. It is designed for ultra-short exposure times in
photoplotters with green laser diodes (500 – 553 nm) or blue argon
lasers (488 nm). Thickness of the polyester base: 0.18 mm (.007”).

Applications

The films are used for high quality work in the PCB industry, chemical milling and for cartographic and

industrial applications with high demands for image quality, scratch resistance and dimensional stability.

Characteristics

  • Sub-mil lines and spaces capabilities
  • Consistent quality and controllable line width
  • Very good dimensional stability
  • Excellent line sharpness and line edge straightness
  • Wide exposure and development latitude also gives accurate line width control
  • Stable chemistry and low consumption
  • High scratch resistance
  • Optimal film transport and vacuum behavior

Example of 20 micron lines / spaces

  • Edge sharpness = 0.5 μm
  • Edge straightness = 0.7 μm
  • Line width variation ± 0.25 μm

Storage

Non-processed photographic film has a limited shelf life. Unopened boxes can be safely kept until the expiry date mentioned on the label. Film boxes are preferably kept flat, at a temperature of 21 °C and at 50% relative humidity. Temperature and relative humidity in the storage room must be kept within strict tolerances to avoid dimensional changes. Remove the outer packaging and the shrink foil before taking the film into the plotter room to avoid dust being dragged into the plotter area.

 

Production guidelines

Workroom lighting

  • RPF: Cyan (blue-green) safelight, e.g. EncapSulite T20/ND.75 filter.
  • OPF: Red light, e.g. Agfa R6 or EncapSulite R20. Temperature and relative humidity must be kept within strict tolerances to avoid dimensional changes. If the conditions in the workroom are different from the storage room, the film should be allowed to acclimatise before use.

Important

Proceed carefully in order not to damage the film when loading the plotter. Take care that film sheets do not

slide on top of each other. Do not apply strong local pressure on the film. Avoid dust contamination. Closely

follow the instructions for use provided by the plotter manufacturer. Avoid stray light during plotting. The correct

exposure will vary, depending on the type of plotter and the processor used. You can run a test to check the

correct line width and the best line sharpness with the highest possible Dmax. Your Agfa representative will be

pleased to give you more information.

Processing

Idealine films can be processed in rapid access machines.

electrolysis (50% image blackness)

Wash: 20 °C for optimum dimensional stability

Packaging

All Idealine films are supplied in special packaging for optimum protection during transportation and

storage. The packaging is humidity tight for best dimensional stability results. A shrink foil protects the

inner packaging against dust and scratches. With the selection of the packaging materials the possibility

to recycle was taken in account. The amount of packaging material is reduced.

Dimensional stability

The combination of the polyester base with the Idealine emulsions ensures maximum dimensional stability.

However the film will stretch with increasing temperature or relative humidity in the workroom. It will shrink with

decreasing temperature or relative humidity conditions. An optimum adjustment of the dryer temperature in the

processor will enable you to produce phototools with correct dimensions. The film characteristics have some

influence on the dimensional stability of phototools, but attention must be paid to the correct working conditions

and the use of film and equipment. Your Agfa representative will be pleased to give you more information.
