EVALUATING THE TEST PRINT
The wet test print must be dried for evaluation as there is a considerable dry down in the highlights accompanied by a slight lightening of the blacks, and a general reduction in con- trast. A blotted 4 x 5 test print can be dried in 2 minutes in a microwave oven set on 'high'. Pick the exposure where the highlights look right and then look at the shadows in that strip if there isn't enough black there for you, the sensitizer needs more con- trast and peroxide must be added which will increase the exposure for the next test. At this point I usually coat another 4 x 5 test sheet, make the contrast adjustment if needed, exposing it at the exposure I think will be correct, process, dry, and reevaluate. After this you should be ready to make the final print.

WASHING AND DRYING PRINTS
The residual metal compounds in the paper after clearing are much easier to remove than their counterparts in silver printing so washing is more easily accomplished. It is important to make sure there are no traces of acid left in the paper after washing which would cause a more rapid deterioration of the print, and this is easily determined at the end of washing by testing the final wash water with litmus paper. Sufficient washing is usually accomplished with 7 or 8 changes 'of water or wash- ing for half an hour in the print washer. Some papers may show a faint yellow cast in the highlights and this is caused by palladium compounds adhering to the cellulose fibers. A soak in Kodak Hypo Clear which will swell the paper fibers followed by more washing will usually take care of the stain.

The print is then air dried on screens (make sure they are clean-chemistry from silver printing will cause stains) or hung on a line with plastic clothes-pins. Finally flatten the print by placing it between two sheets of acid free paper and putting it in a dry mount press at about 200OF for 30 seconds, after which it is ready for spotting and final presentation.
