Abstract
Abstract A method of making a photographic print having improved sharpness, clarity, texture and highlight definition, suitable for use in dye-transfer printing, engraving, lithography, offset, and the like, involves the production of a primary color separated negative of the image to be printed on a panchromatic film, producing a separated color positive from the separated color negative, producing a reversal positive from the separated color positive on direct reversal film so as to produce a panchromatic primary color separated reversal positive, producing a composite separation negative from the separated color positive and the reversal positive, and producing the desired photographic positive from the composite negative.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A method of making a primary color separated negative of improved sharpness, clarity, texture and definition suitable for use in printing which comprises a. making a primary color separated negative on panchromatic film of the image to be printed; b. making a separated primary color positive on panchromatic film from the separated color negative; c. making a reversal primary color positive from the separated color positive on direct reversal film so as to produce a panchromatic primary color separated reversal positive; and d. making a primary composite color separated negative from the separated color positive and the primary reversal positive.
Claim 2
Independent Claim
100 words
A method of making a primary color separated negative of improved sharpness, clarity, texture and definition suitable for use in printing which comprises a. making a primary color separated negative on panchromatic film of the image to be printed; b. making a separated primary color positive on panchromatic film from the separated color negative; c. making a reversal primary color positive from the separated color positive on direct reversal film so as to produce a panchromatic primary color separated reversal positive; and d. making a primary composite color separated negative from the separated color positive and the primary reversal positive.
Claim 3
Dependent Claim
44 words
The method of claim 1 wherein the composite negative is made by the exposure of light through the separated color positive and the reversal positive onto a negative film, the images from the separated color positive and reversal positive having been placed in registry.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein said method is used to make each of the composite primary color separated photographic negatives.
Claim 5
Dependent Claim
20 words
The method of claim 3 wherein the resulting photographic negatives are utilized to produce a colored print by dye-transfer printing.
Claim 6
Dependent Claim
19 words
The method of claim 3 wherein the resulting photographic negatives are utilized to produce a colored print by photolithography.
Claim 7
Dependent Claim
16 words
The method of claim 3 wherein the composite negatives are used to make a positive print.
Claim 8
Dependent Claim
13 words
The method of claim 6 wherein positive prints are made on matrix film.
Claim 9
Independent Claim
68 words
A method of making photographic print of improved sharpness, clarity, texture and definition, suitable for use in printing which comprises making a panchromatic primary color separated reversal positive of the image to be printed, and making a composite primary color separated negative from the panchromatic primary color separated reversal positive and another positive of the image to be printed, and making a photographic print from the composite negative.
Claim 10
Independent Claim
68 words
A method of making photographic print of improved sharpness, clarity, texture and definition, suitable for use in printing which comprises making a panchromatic primary color separated reversal positive of the image to be printed, and making a composite primary color separated negative from the panchromatic primary color separated reversal positive and another positive of the image to be printed, and making a photographic print from the composite negative.
