Abstract
A process and system for depicting a combination of process colors and spot colors on a radiant light source such as a computer monitor screen. The invention provides a user-definable “meta-ink” color which is made up of the components of the process colors and the spot colors. Shade values are assigned to each of these components to create the meta-ink color. This meta-ink color then replaces the document color for visual depiction on the radiant light source. This process and system provides a more accurate depiction of the representation of the printed image.
Claims18
A system for determining a coordinate set for visual depiction onto a computer monitor of a process color having at least one spot color applied to it, said system comprising:
- means for defining the process color into process color components and percentage values;
- means for defining the at least one spot color into spot color components and percentage values;
- means for converting said process color components and their percentage values into a coordinate set values for visual depiction;
- means for determining said coordinate set values of said at least one spot color components;
- means for applying percentages to said coordinate set of values of said at least one spot color components according to said percentage values for said at least one spot color components;
- means for determining a value for said percentages of said at least one spot color components layered onto said coordinate set of values converted from said process color components;
- and
- means for converting said determined value for said percentages of said at least one spot color components layered onto said coordinate set of values converted from said process color components into said coordinate set.
A system for visually depicting a document having at least one spot color applied onto a document process color on a computer monitor screen, said system comprising:
- means for defining the document process color;
- means for defining each of at least one spot colors to be applied onto the document process color;
- means for applying shade values to each of said document process color;
- means for applying shade values to each of said at least one spot colors;
- means for defining a new color based on the shade values applied for each of said document process color and for each of said at least one spot color;
- and
- means for applying said defined mew color to a document depicted visually on a computer monitor screen.
A process for digitally depicting a document having a combination of process colors and spot colors on a computer monitor screen, said process comprising the steps of:
- defining the process colors;
- defining the spot colors;
- assigning shade values to each of said process colors;
- assigning shade values to each of said spot colors;
- defining a color based on the combination of said assigned shade values for each of said process colors and for each of said spot colors;
- and
- applying said defined color to the document visually depicted on the computer monitor screen.
A system for digitally defining a color formed from at least two color models, said system comprising:
- means for selecting at least one color component from a first color model;
- means for selecting at least one additional color component from at least one other color model;
- and
- means for assigning percentages to each of said selected color components from said first color model and from said at least one other color model to create a user-defined color.
