Method and apparatus for making color prints

Claim 1

THE METHOD OF MAKING A COLOR PRINT FROM A COLOR NEGATIVE ON A COLOR PRINT MATERIAL WHICH COMPRISES THE STEPS OF ILLUMINATING SAID NETGATIVE WITH A LIGHT SOURCE INCLUDING THE THREE PRIMARY COLORS, RED, BLUE AND GREEN; PROJECTING AN IMAGE OF SAID ILLUMINATED NEGATIVE ONTO SAID COLOR PRINT MATERIAL; INDIVIDUALLY AND EXCLUSIVELY MEASUREING THE TOTAL INTEGRATED RED, GREEN AND BLUE TRANSMITTANCES OF SAID NEGATIVE; TERMINATING THE RED, GREEN AND BLUE EXPOSURES OF SAID PRINT MATERIAL BY INDIVIDUALLY INSERTING SUBTRACTIVE PRIMARY FILTERS INTO THE NEGATIVE TRANSMITTED LIGHT BEAM AHEAD OF SAID PRINT MATERIAL AT INTERVEALS DETERMINED IN ACCORDANCE WITH THE DIFFERENCE BETWEEN SAID INDIVIDUALLY AND EXCLUSIVELY MEASURED INTEGRATED TRANSMITANCE OF SAID NEGATIVE AND CORRESPONDING INTERGRATED TRANSMITTANCES WHICH IN COMBINATION WOULD PRINT THE NEGATIVE SUBSTANTIALLY AT A FULL DENSITY CORRECTION LEVEL; CHARCTERIZED IN THAT SAID SUBSTRACTIVE FILTERS ARE INSERTED INTO THE PRINTING SYSTEM BEYOND THE POINT AT WHICH THE MEASUREMENTS OF THE RED, GREEN AND BLUE NEGATIVE TRANSMITTANCES ARE MADE IN ORDER TO OBAIN LOWERED COLOR CORRECTION WHILE MAINTAINING SUBSTANTIALLY FULL DENSITY CORRECTION IN THE EXPOSURE BY VIRTUE OF THE FACT THAT THE NON-MAJOR ABSORBENCIES OF THE FILTERS ARE IGNORED IN THE DETERMINATION OF THE TIME OF EXPOSURE FOR EACH OF THE PRIMARY COLORS, WHEREAS THE NON-MAJOR ABSROBENCIES OF THE FILTERS ACT TO REDUCE THE INTENSITY OF THE INDIVIDUAL COLOR EXPOSURES IN ACCORDANCE WITH THE ORDER IN WHICH SAID FILTERS ARE MOVED INTO THE NEGATIVE TRANSMITTED LIGHT BEAM.

Claim 2

THE METHOD OF MAKING A COLOR PRINT FROM A COLOR NEGATIVE ON A COLOR PRINT MATERIAL WHICH COMPRISES THE STEPS OF ILLUMINATING SAID NETGATIVE WITH A LIGHT SOURCE INCLUDING THE THREE PRIMARY COLORS, RED, BLUE AND GREEN; PROJECTING AN IMAGE OF SAID ILLUMINATED NEGATIVE ONTO SAID COLOR PRINT MATERIAL; INDIVIDUALLY AND EXCLUSIVELY MEASUREING THE TOTAL INTEGRATED RED, GREEN AND BLUE TRANSMITTANCES OF SAID NEGATIVE; TERMINATING THE RED, GREEN AND BLUE EXPOSURES OF SAID PRINT MATERIAL BY INDIVIDUALLY INSERTING SUBTRACTIVE PRIMARY FILTERS INTO THE NEGATIVE TRANSMITTED LIGHT BEAM AHEAD OF SAID PRINT MATERIAL AT INTERVEALS DETERMINED IN ACCORDANCE WITH THE DIFFERENCE BETWEEN SAID INDIVIDUALLY AND EXCLUSIVELY MEASURED INTEGRATED TRANSMITANCE OF SAID NEGATIVE AND CORRESPONDING INTERGRATED TRANSMITTANCES WHICH IN COMBINATION WOULD PRINT THE NEGATIVE SUBSTANTIALLY AT A FULL DENSITY CORRECTION LEVEL; CHARCTERIZED IN THAT SAID SUBSTRACTIVE FILTERS ARE INSERTED INTO THE PRINTING SYSTEM BEYOND THE POINT AT WHICH THE MEASUREMENTS OF THE RED, GREEN AND BLUE NEGATIVE TRANSMITTANCES ARE MADE IN ORDER TO OBAIN LOWERED COLOR CORRECTION WHILE MAINTAINING SUBSTANTIALLY FULL DENSITY CORRECTION IN THE EXPOSURE BY VIRTUE OF THE FACT THAT THE NON-MAJOR ABSORBENCIES OF THE FILTERS ARE IGNORED IN THE DETERMINATION OF THE TIME OF EXPOSURE FOR EACH OF THE PRIMARY COLORS, WHEREAS THE NON-MAJOR ABSROBENCIES OF THE FILTERS ACT TO REDUCE THE INTENSITY OF THE INDIVIDUAL COLOR EXPOSURES IN ACCORDANCE WITH THE ORDER IN WHICH SAID FILTERS ARE MOVED INTO THE NEGATIVE TRANSMITTED LIGHT BEAM.
