  • Moderately high contrast, orthochromatic film.
  • Projection or contact speed.
  • Direct-image duplication of printed-circuit masters, engineering drawings, and line negatives generated on photoplotters.
  • Low matte level.
  • Dyed gel backing (green) for halation protection and to permit exposure through the base when required.
  • Dimensionally stable ESTAR Base and ESTAR Thick Base.
  • Suitable for lith or rapid access development.

These films are suitable for making one-step duplicates — either to the emulsion or through the base — using a process camera, enlarger, or contact printer. They are intended for duplicating printed-circuit masters, engineering drawings, maps, renderings, or similar positive or negative line copy. They are also suitable for printed circuit board positives on vector-type photoplotters, and can be used for the initial reduction in multiple-reduction systems.

Use a KODAK 1A Safelight Filter / light red, in a suitable safelight lamp equipped with a 15-watt bulb. Keep the film at least 1.2 metres (4 feet) from the safelight.

Keep unexposed film and processed film in a cool, dry place. Process film as soon as possible after exposure.

These films can be exposed by either projection or contact methods in a photoplotter, process camera, enlarger, or contact printer. Since this is a direct-reversal film, an increase in exposure or a decrease in development will cause a reduction in image density.

  • Photoplotter Exposure:
    The exposure required is a function of both the photoplotter characteristics and development conditions. To determine the optimum exposure, trials will need to be run.
  • Line or Camera Exposure:
    For a same-size (1:1) line reproduction with two 1500-watt pulsed-xenon lamps at 0.9 metre (3 feet) from the copyboard, use the following time for trial exposures: 8 seconds at f/22

    Note: It is recommended that the manufacturer of the pulsed-xenon or quartz-halogen lamps be consulted for safety information pertaining to ultraviolet radiation and ventilation requirements due to ozone generation.

  • Contact Exposure:
    Recommended exposures should be used as test guides. Expose a contact using a variable voltage point-source 100-watt lamp, set at 16 volts at a distance of 1.5 metres (5 feet) from the exposure plane. Provide approximately 4.0 footcandles of illumination (43.0 lumens/sq metres). Use the following times for trial exposures:


    Exposure Time[1]


    4 to 8 seconds


    5 to 10 seconds

    [1] The indicated time is for exposure to the emulsion, with lith development. Increase by 25% for exposure through the base; by 60% for non-lith development; or by 100% with both changes.

  • Relative Exposure Index
    These indexes are provided primarily as indicators of the relative speed of this film when compared with other Kodak graphic arts films or KODAK PRECISION LINE Films using pulsed-xenon, tungsten, or quartz-halogen light sources.

Dimensionally stable support:

ESTAR Thick Base

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 and aging. The absence of solvent in ESTAR Base is one of the reasons why ESTAR Base films show excellent dimensional stability. The dimensional properties of ESTAR Base may vary slightly in different directions within a sheet; the differences that may exist, however, are not always equal in both the length and width directions.

Differences in size change between length and width should be within 10% of each other.

Determined in accordance with ISO Standard, see TI1450 for footnotes.

Thermal Coefficient of Linear Expansion —

Unprocessed or processed:

0.0018% per degree C


0.001% per degree F

Humidity Coefficient of Linear Expansion —



0.0020% per % RH



0.0017% per % RH



0.0015% per % RH

Processing Dimensional Change —

Dependent upon drying conditions.


With recommended processing, the reciprocity speed change is negligible (1/3-photographic stop or less) within exposure range of 1/1000 second 100 seconds; there is no change in contrast.
