KODAK EKTACHROME RADIANCE III Clear Display Material

Using an Enlarger

You can also use this material to make overheads from slides
with a conventional enlarger without first making
internegatives. Equip the enlarger with a heat-absorbing
glass, and use color-correction filters and a voltage regulator.
If you are using color-compensating or color-printing filters,
do not use cyan filters with the suffix “2” as in “CC10C-2” or
“CP10C-2.” You will not need an ultraviolet-absorbing filter.

To make a print 50.8 x 61.0 cm (20 x 24 inches) from a

35 mm slide, use the following adjustments for your trial
exposure with a Durst Optimo AC Enlarger (dichroic filters,
tungsten/halogen light source, 50 mm lens).

Printing Digital Images

KODAK EKTACHROME RADIANCE III Clear Display
Material can be used as an output medium with digital
images on a Durst Lambda Laser Imager. For optimum
results, refer to your equipment manufacturer’s
recommendations for calibration information.

With a Durst Lambda 130 Imager:

Adjustment for Long or Short Exposures

Regardless of the type of light source and exposure time,
there is little or no change in speed or contrast with
EKTACHROME RADIANCE III Clear Display Material.

LATENT-IMAGING KEEPING

A very limited sensitometric variation is noticeable within
the first few minutes after exposure. Beyond 5 minutes after
exposure, there is no significant variation up to several days.

PROCESSING

Use KODAK EKTACHROME R-3 or R-3 LU Chemicals to
process these materials in continuous or roller-transport
processors. In most instances, these materials will require
increased replenishment rates. For specific processing
instructions, see KODAK Publication No. Z-129B, Using
KODAK EKTACHROME R-3 Chemicals in Continuous and
Roller-Transport Processors,
available from our website at
www.kodak.com/go/photochemicals.

DRYING

Drying conditions for these materials are different from
those used for EKTACHROME RADIANCE III Papers
because of the gelatin anti-curl backing on the base side.

If you process the material in a continuous processor, use

double-bladed squeegees following the final wash. Use a
dryer that blows air on both sides of the material. If your
dryer does not have that capability, you will need to increase
the drying temperature. Remember to set the temperature
back before processing paper again; otherwise, you may
have transport problems and excessive curl in the paper.

VIEWING

Evaluate display transparencies under conditions similar to
those you will use for viewing them. Remember that
EKTACHROME RADIANCE III Clear Display Material is
intended for use with translucent light boxes for display
presentations.

DISPLAYING

Photographic dyes, like all dyes, can change with time and
exposure to sunlight, ultraviolet radiation, excessive heat,
and high humidity. To help prevent changes in photographic
dyes, follow these guidelines:

• Display prints with the lowest-light level consistent with

viewing needs.

• Maintain temperature and low humidity.
