Set new standards for phototool production with KODAK
ACCUMAX Photoplotter Film ABG7. This advanced filmdelivers superb image quality and line sharpness withraster imaging photoplotters that use blue-green laser lightsources.

SUPPORT
Dimensionally stable support.
7-mil (0.18 mm)

ESTAR Thick Base• Extremely high contrast, blue/green sensitive film.

DARKROOM RECOMMENDATIONS• Designed to produce high quality phototools on raster
imaging photoplotters, and other artwork generatorswith output at 488, 532, 543, and 565 nanometres.

Use a KODAK 1A Safelight Filter / light red in a suitablesafelight lamp equipped with a 15-watt bulb.
Darkrooms can also be illuminated with the following
EncapSulite Filters: R10, R20, or S15ND2.25.
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. These filters should
provide up to 2 minutes of acceptable safelight
performance, under the stated conditions.

• High photographic speed for longer laser life
• Dimensionally stable emulsion.
• Excellent scratch and abrasion resistant overcoat.
• Coated on a dimensionally stable ESTAR Base with
antistatic and surface properties to ensure
dependable transport and handling behavior. This
property also helps to resist attraction of dirt and dust.
• Excellent line-edge acuity for critical phototools.
• Contains ultra-fine matte on the emulsion side toimprove handling and vacuum draw-down to photoresist.
• Excellent reciprocity characteristics for dependable
photoplotting performance.

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

• Can be handled under light red (series 1A) safelight.

EXPOSURE• Recommended for processing in KODAK ACCUMAX
Rapid Access Developer and Replenisher.

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 required line width andD-max. The resulting image quality and D-max can be
influenced by variations in time and temperature ofdevelopment. Many customers may find that a change tothe recommended time and temperature will provide amore suitable result for their particular exposingconditions.

ABG7 Film is designed for use with the following

RECIPROCITYDIMENSIONAL STABILITY

With recommended processing, the reciprocity speed
change is negligible within exposure range of
1/1000 second to 100 seconds, there is no change incontrast.

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; thedifferences that may exist, however, are not always equal inboth the length and width directions.
Differences in size change between length and width
directions should be within 10 percent of each other.

* Anti-oxidation replenishment rates should be set to achieve one tankturnover per week.
† 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(CAT No. 173 3013, 72-ounce bottle). Start with 8 mL of Part B
per litre of well mixed, working strength fixer, and increase as necessary to amaximum of 25 mL per litre. Add Part B slowly and mix thoroughly.

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.
