514 XIV. DUPLICATION OF TRI-PACK COLOE FILMS Production Quality Control of Prints There is much to recommend the routine testing of every roll of film printed. It is necessary to establish quality control in printing and to maintain control once it has been established. Routine testing is required for every other element entering into the process. Commerical color duplication in Kodachrome is therefore exacting and demanding, yet interesting work. The starting point is a lamp, the color temperature of which is known. 3300 3200 3000 2900 2800 2700 2600 2500 °K Ampere s 1 70 6b 55 E 45 40 35 30 50 60 70 80 90 VOLTS 100 no Fig. 122. Volts vs. color-temperature and amperes characteristics of 500-w, 105-v, T-10 lamp. The color temperature is not known, however, unless the limits to which it has been measured are also known. The same electrical testing laboratories that provide recording spectrophotometer services can also determine the current at which a particular lamp will reach the desired color temperature. If a lot of 50 lamps of the same type is tested, the cost for a measurement within a tolerance of ± 10 K is but a fraction of the cost of the lamp itself. Should seasoning or aging be required, these laboratories can provide such service at very low cost. With such reliable services available at low rates, no commercial laboratory engaged in the
