Green Red GREEN Red Blue Green BLUE Red Green Blue KODAK PROFESSIONAL ULTRA III Paper e E 142 LATENT IMAGE KEEPING This paper features improvements in the stability of the latent image Under normal conditions you should not notice shifts in the latent image with keeping times from 1 minute to 24 hours Therefore you do not need to change your printing procedures to compensate for latent image shifts under normal temperature and handling conditions If shifts do occur you can minimize them by keeping the time between exposure and processing the same for all paper PROCESSING Use KODAK EKTACOLOR RA Chemicals for Process RA 4 to process this paper For information on processing this paper in continuous or roller transport processors see KODAK Publication No Z 130 Using KODAK EKTACOLOR RA Chemicals For information on processing this paper in trays or rotary tube and drum processors see KODAK Publication No J 39 Tray Drum and Rotary Tube Processing with KODAK EKTACOLOR RA Chemicals Both publications are available through our website at www kodak com go photochemicals Use a drying temperature below 205 F 96 C Do not ferrotype this paper the F surface dries to a natural gloss without ferrotyping VIEWING Evaluate prints under light of the same color and brightness that you will use to view the final prints A good average viewing condition is a light source with a color temperature of 502. the manufacturer s instructions Do not use fluorescent lamps to expose this paper Use a heat absorbing glass to remove infrared radiation Because voltage changes affect light output and color quality use a voltage regulator Keep negatives and the equipment optical system clean Mask negatives to eliminate stray light You can use the white light or the tricolor exposure method White Light Exposure Method Control color balance with dichroic filters built into the printer or enlarger or with KODAK Color Printing CP Filters Acetate placed between the lamp and the negative You can use any number of filters between the light source and the negative If you use cyan filtration use filters with the suffix 2 e g CP10C 2 1 Start with a filter pack of 50M 70Y to make a test print 2 Evaluate the test print under light of the same color and brightness that you will use to display the final print See Viewing 3 Judge print density first If necessary make another print by adjusting the exposure as recommended in the table below satis Dothis OR _ Dothis Open the lens aperture to Increase the TOO LIGHT increase the light exposure time level Close the lens aperture to Decrease the TOD DABS decrease the light exposure time level 4 Then judge the color balance You can use the KODAK Color Print Viewing Filter Kit KODAK Publication No R 25 to evaluate your test pri
