June 2019• TI-2585
Creating high-complexity phototools starts with the rightfilm. Now from Kodak, you get a hard, line-edge quality andgood dimensional stability with KODAK ACCUMAX
Photoplotter Film RED7. RED7 Film uses the latest
Integrated-Booster-Technology (IBT processing)—
technology pioneered by Kodak. Some of its outstanding
features include:• Extremely sharp line-edge quality, with the latest inIntegrated Booster Technology processing,recommended for processing in IBT compatible
developers such as KODAK ACCUMAX Rapid Access
Developer and Replenisher.
• Suitable for lines and spaces as small as 1 mil andphotoplotter resolution settings as high as 12,000 DPI.
• Rapid processing, as fast as 30 seconds development
time, for high productivity.
• Emulsion side matte to provide rapid draw-down tophotoresist.
• Excellent resistance to photoabrasion and physicalwear.
• Permanent anti-static performance to resist theattraction or dust and dirt.
• Dual red sensitivity at 633 nm and 670 nm for use withphotoplotters using helium-neon (HN) or
red-laser-diode (RLD) exposing sources.
• Very good line reproduction on photoresist.
RED7 Film is designed for use with the following
photoplotters:

ESTAR Thick BaseDARKROOM RECOMMENDATIONS
Darkrooms can be illuminated using an EncapSulite
T20/ND0.75 "cyan" filter.
The light should be at least 1.2 metres (4 feet) from any
area where the film will be handled. Where possible, thesafelights should be located as to maximize room lighting
for safety but minimize direct exposure to the film surface
itself. The farther away the lights are located from the film,
the greater the margin of safety. This filter should provide
up to 2 minutes of acceptable safelight performance, under
the stated conditions.

STORAGE AND HANDLING
Keep unexposed film and processed film in a cool, dryplace. Process film as soon as possible after exposure.

EXPOSURE
The exposure required is a function of both thephotoplotter characteristics and development conditions.
Optimum exposure must be determined by means of a trial
exposure series following the equipment manufacturer’srecommended procedures. The calibration test will
determine optimum exposure for the required line widthand D-max. The resulting image quality and D-max can beinfluenced by variations in time and temperature ofdevelopment. Some customers may find that a smallchange to the recommended time and temperature will
provide improved results for their particular exposingconditions.

Exposure Conversion Factors
When converting from another film, the following
exposure factors can be used as a starting point. Multiply
your current laser intensity setting by the factors as astarting point. An exposure sweep of over and under
exposure is strongly recommended to determine optimum
laser intensity. Please note the factors assume processingin the recommended developer and processing conditions
as specified by the manufacturer.

RECIPROCITY
With recommended processing, the reciprocity speed
change is negligible (1 ⁄3-photographic stop or less) within
exposure range of 1/1000 second to 1 billionth second;
there is no change in contrast.

Recommendations at Setup:✔

Confirm processing time and temperature with calibrated
stopwatch and digital thermometer. Adjust control settings
to achieve the desired set points✔

Measure replenishment rates with a graduated cylinder orbeaker. Adjust replenishment settings to deliver required
volume of developer and fixer for sheet size being used.

DIMENSIONAL STABILITY
Dimensional stability is an all-inclusive term. In
photography, it applies to size changes caused by changes
in humidity and in temperature, and by processing andaging. The dimensional properties of ESTAR Base may varyslightly in different directions within a sheet. The
differences that may exist, however, are not always equal inboth the length and width directions.
Differences in size changes between length and width
should be within 10 percent of each other.

* Anti-oxidation replenishment should be set to achieve one tank turnover perweek.
† As a starting point, do not add hardener to the fixer. If abrasion or transport

problems occur in processing, a small amount of KODAK Rapid Fixer, Part B
can be added. Start with 1 oz. of Part B per working strength gallon of fixer,
and increase as necessary to a maximum of 3.2 oz. per gallon. Follow theinstructions for adding Part B—slowly and mixing thoroughly.
