Method and apparatus for color print management
View Patent ↗In a color printing environment, functions for printing color management are dissociated. An abstraction layer is also provided to facilitate setting and evaluation of all factors relating to color print and prediction.
1. A method for visualizing a dedicated ink layer in a color comprised of two or more inks, comprising:
establishing a virtual color space comprising a virtual workspace between a first color space and a printing space having n data size and a percent color separation, wherein the percent of each color in the printing space is equivalent to a single virtual color having separation values required to obtain an expected color rendering before separation into separate layers for printing, and wherein a change of a percent effects a display of a resulting color rendering;
generating, using said virtual color space, one or more virtual color profiles each of which only contains color values relative to one of said two or more inks;
selecting one of said one or more virtual color profiles;
displaying said selected virtual color profile in said virtual color space in relation to said color;
wherein adjustment of said selected profile displays a visualization of said ink as modified by said adjustment; and
establishing a proof before a post-printing operation (PPO), comprising:
a processor defining a link between a color space before said PPO and a color space after said PPO by measuring a printing sample before said PPO and after said PPO and applying said link to said color space before said PPO during a subsequent printing process.
2. A method for non-destructive visualization of a print file, comprising:
establishing a virtual color space comprising a virtual workspace between a first color space and a printing space having n data size and a percent color separation, wherein the percent of each color in the printing space is equivalent to a single virtual color having separation values required to obtain an expected color rendering before separation into separate layers for printing, and wherein a change of a percent effects a display of a resulting color rendering;
modifying a particular virtual color space profile to create a predefined treatment;
matching one or more color values corresponding to a source file from a known and defined space to said predefined treatment in said virtual color space;
displaying, by using said modified virtual color space profile, a final color result corresponding to said matched one or more color values, before altering said file; and
establishing a proof before a post-printing operation (PPO), comprising:
a processor defining a link between a color space before said PPO and a color space after said PPO by measuring a printing sample before said PPO and after said PPO and applying said link to said color space before said PPO during a subsequent printing process.
