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:

D-min	Basic Calibration
	(Starting Values)
R = 10	Y = 41
	M = 0
G = 10
	C = 71.3
B = 10
	D = 37.7

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.

Exposure Time	Filter	Exposure
Range		Correction
0.5 to 10 seconds	None	+1⁄ 3 stop
10 to 100 seconds	CC05Y or equivalent	None

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.
