GETTING PRINTING EQUIPMENT READY
Set out the equipment in the order shown in Figure 5. From left to right , first comes the printing frame and a source of white light above it - any small desk lamp will do nicely although it may be necessary to raise it somewhat as shown in Figure 5 if it is quite small . It is generally more convenient to work from left to right , but you can reverse the order , or you can even expose the paper at one table and develop at another if you wish . Then come three trays , with the safelight above the first , and the darkroom clock wherever most convenient .
Figure 3 Contact proof sheet of a roll of 120 ( 2 x 2 ) film .
Figure 4 This is the same contact sheet as in Figure 3 , only given more exposure time . Thus with 2 exposures you have a good proof of each negative in the roll .
Figure 5 Working layout of equipment for contact printing . A left to right arrangement is normally used .
Dissolve the packaged developer in water according to the directions supplied with it . Check the developer temperature - it should be the same as that of the room . If it isn't , adjust its temperature by placing it in warm or cold water . Stir the solution thoroughly every two or three minutes and take readings until the temperature is normal . The best temperature range is 65 ° to 75 anything up to 80 ° or even 85 ° F . will do for printing . When the developer is at the correct temperature , pour it into the first tray . Figure 6 .
Figure 6 After checking the temperature of the developer , pour it in the left hand tray .
Pour stop bath into the middle tray to fill it about half full . The simplest way to prepare a stop bath is to add 1½ ounces of 28 % acetic acid to a quart ( 32 ounces ) of water .
Dissolve the packaged fixer in accordance with the directions supplied with it and adjust its temperature as you did the developer . Since prepared fixer keeps well , it is usually put up in packages that make either one quart or one gallon of solution . When you have dissolved it , pour it into a suitable bottle with a plastic ( not metal ) cap for storage . Pour enough of the fixing solution into the third tray to fill it comfortably . This is about 32 ounces for an 8 x 10 tray .
