Abstract

Abstract Color printing is a precise and exacting science. The finished piece should be a perfect meld between type and graphic. To accomplish this, a color chart must be used to match a particular color in the photograph or in a slide, as is more commonly used. The match is then incorporated in the headline or body copy. When using a photograph, it is fairly simple to pick and match a color from the chart because they are both reflective. But working with the reflective chart and the transparency, the slide poses a problem. The designer has to visualize and interpolate. With this invention, the chart and slide is transparent. In this invention, the four colors, magenta, cyan, yellow, and black with screens from ten percent to 90 percent for each are selected to match a particular color or a complement of all the colors in the slide. By overlaying any one or more of the primary colors and/or their screens, the designer can specify those colors for the headline, body copy, or a frame.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 89 words
A method for matching the color of a color transparency in the process of color printing comprising the steps of: (a) selecting from a series of screen transparencies of magenta, cyan, yellow and black graduated in a consistent progression of color gradation, at least one of said screen transparencies; (b) placing said screen transparency adjacent to said color transparency; (c) comparing the color of said screen transparency with the color of said color transparency; and (d) if necessary, sequentially repeating steps (a), (b) and (c) until the colors match.
Claim 2
Independent Claim 89 words
A method for matching the color of a color transparency in the process of color printing comprising the steps of: (a) selecting from a series of screen transparencies of magenta, cyan, yellow and black graduated in a consistent progression of color gradation, at least one of said screen transparencies; (b) placing said screen transparency adjacent to said color transparency; (c) comparing the color of said screen transparency with the color of said color transparency; and (d) if necessary, sequentially repeating steps (a), (b) and (c) until the colors match.
Claim 3
Dependent Claim 14 words
The method of claim 8, wherein the screen transparencies are graduated in 10% increments.
Claim 4
Dependent Claim 23 words
The method of claim 1 wherein more than one of said screen transparencies are overlaid to form the resultant comparative screen transparency color.
Claim 5
Independent Claim 103 words
A method for matching the color of a color transparency in the process of color printing comprising the steps of: (a) placing said color transparency on a light table; (b) selecting from a series of screen transparencies of magenta, cyan, yellow and black graduated in a consistent progression of color graduation at least one of said screen transparencies; (c) placing said selected screen transparency on said light table adjacent to said color transparency; (d) comparing the color of said color transparency with the color of said screen transparency; and (e) if necessary, sequentially repeating steps (b), (c) and (d) until the color match.
Claim 6
Independent Claim 103 words
A method for matching the color of a color transparency in the process of color printing comprising the steps of: (a) placing said color transparency on a light table; (b) selecting from a series of screen transparencies of magenta, cyan, yellow and black graduated in a consistent progression of color graduation at least one of said screen transparencies; (c) placing said selected screen transparency on said light table adjacent to said color transparency; (d) comparing the color of said color transparency with the color of said screen transparency; and (e) if necessary, sequentially repeating steps (b), (c) and (d) until the color match.
Claim 7
Dependent Claim 14 words
The method of claim 4 wherein the screen transparencies are graduated in 10% increments.
Claim 8
Dependent Claim 23 words
The method of claim 4 wherein more than one of said screen transparencies are overlaid to form the resultant comparative screen transparency color.
