Abstract
Abstract A method of printing on a sheet member a realistic image of an original, uses two different superimposed impressions with two different coloring media. A first printing plate is created by interposing at least two filters between the original and the film or photoconductive surface, and a second printing plate is created by interposing at least one filter between the original and the film or photoconductive surface. Then, the two printing plates are used to print the different impressions with two different coloring media.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
204 words
A method of printing on a sheet member a realistic reproduction of a colored original, utilizing a minimum of two different superimposed impressions, each with a different coloring medium, comprising: (a) providing a colored original, (b) creating a first printing plate intended to print a non-process red color, by (1) making a green filter exposure of the original on a first means for recording a first optical image, (2) making a blue filter exposure of the original on said first means, steps (1) and (2) being carried out sequentially in any order, (c) creating a second printing plate intended to print a second color different from that printed by said first plate, by (3) making a red filter exposure of the original on a second means for recording a second optical image, (4) making a blue filter exposure of the original on said second means, steps (3) and (4) being carried out sequentially in any order, (steps (b) and (c) being carried out in any order, (d) providing a sheet member to receive two superimposed impressions, and (e) using said first and second printing plates to print said red color and said different color, respectively, as the said superimposed impressions on said sheet member.
Claim 2
Independent Claim
204 words
A method of printing on a sheet member a realistic reproduction of a colored original, utilizing a minimum of two different superimposed impressions, each with a different coloring medium, comprising: (a) providing a colored original, (b) creating a first printing plate intended to print a non-process red color, by (1) making a green filter exposure of the original on a first means for recording a first optical image, (2) making a blue filter exposure of the original on said first means, steps (1) and (2) being carried out sequentially in any order, (c) creating a second printing plate intended to print a second color different from that printed by said first plate, by (3) making a red filter exposure of the original on a second means for recording a second optical image, (4) making a blue filter exposure of the original on said second means, steps (3) and (4) being carried out sequentially in any order, (steps (b) and (c) being carried out in any order, (d) providing a sheet member to receive two superimposed impressions, and (e) using said first and second printing plates to print said red color and said different color, respectively, as the said superimposed impressions on said sheet member.
Claim 3
Dependent Claim
14 words
The method claimed in claim 1, in which the second color is non-process green.
Claim 4
Dependent Claim
15 words
The method claimed in claim 1, in which the second color is a non-process blue.
Claim 5
Dependent Claim
14 words
The method claimed in claim 1, in which the second color is non-process black.
Claim 6
Dependent Claim
32 words
The method claimed in claim 1, in which each printing plate is a photoconductive surface in a reproduction system using electrostatic images created by exposure to light, and a plurality of toners.
Claim 7
Dependent Claim
21 words
The method claimed in claim 5, in which the same photoconductive surface is used sequentially to provide the two printing plates.
Claim 8
Dependent Claim
110 words
The method claimed in claim 6, in which the green filter exposure time under step (b)(1) is no less than a normal exposure time for making a magenta printing plate in the conventional four color process; in which the blue filter exposure time under step (b)(2) is less than 15% of the expsoure time under step (b)(1); in which the red filter exposure time under step (c)(3) is no less than a normal exposure time for a making a cyan printing plate in the conventional four color process; and in which the blue filter exposure time under step (c)(4) is less than 10% of the exposure time under step (c)(3).
Claim 9
Dependent Claim
22 words
The method claimed in claim 7, in which the second color is chosen from the group: non-process green, non-process blue, non-process black.
Claim 10
Dependent Claim
36 words
The method claimed in claim 1, in which said first and second means are two pieces of photographic film exposed through filters to the illuminated original, the printed colors being made by translucent colored printing inks.
Claim 11
Dependent Claim
116 words
The method claimed in claim 9, in which the exposure time for the green filter under step (b)(1) is no less than a normal exposure time for making a magenta printing plate in the conventional four color process; in which the exposure time for blue filter under step (b)(2) is less than 15% of the exposure time under step (b)(1); in which the exposure time for the red filter under step (c)(3) is no less than a normal exposure time for making a cyan printing plate in the conventional four color process; and in which the exposure time for the blue filter under step (c)(4) is less than 10% of the exposure time under step (c)(3).
Claim 12
Dependent Claim
22 words
The method claimed in claim 10, in which the second color is chosen from the group: non-process green, non-process blue, non-process black.
