Embodiment Construction

[0021]The present invention anticipates quantifying the mixing characteristics of the system by describing the characteristics of the additivity degradation of the reflective multicolor reproduction system (RM / CRS) using the pigment set. The present invention attempts to use RM / CRS, such as reflective four-color CRS (R4 / CRS), three-color CRS (R3 / CRS), and / or other applicable multi-color systems currently known or developed in the future. In addition, the method and system of the present invention are expected to make all aspects of the color management process easier. In this process, RM / CRS is used through characterization, and it is expected to compensate for several variables, such as tone reproduction, scale decay rate, The mixing characteristics of the system do not match the color gamut used by imaging experts when describing the characteristics of color reproduction.

[0022] The color gamut mismatch can be generated by: a) the mismatch of the solid density and hue of the s...

Abstract

A method provides reference profile density values for at least one color combination having a plurality of colors produced by a reference device using a reference colorant set, at least one overprint color combination having reference initial percent dot values (IPDVs); providing current profile density values for at least one color combination produced by a current device using a current colorant set, at least one color combination produced by the current colorant set having current IPDVs; quantifying reference theoretical percent dot values (TPDVs) as efficiency attributes using reference colorant set; quantifying current TPDVs as efficiency attributes using the current colorant set; and calculating factors that compensate for at least one difference between image data produced with the reference colorant set and image data to be printed with the current colorant set in response to reference efficiency attributes and current efficiency attributes, factors used to adjust and generate image data.

Description

Technical field [0001] The present invention generally relates to the field of printing, and more particularly to a system hybrid compensation system and method. Background technique [0002] For customers who have long been accustomed to printing with black and white ink dots or using only one or two pre-mixed ink dots, color printing on an offset press is relatively reliable and affordable. This printing method uses photochemical technology, which can restore the multi-color originals used in printing to four component colors. For example, the current printing of color images usually uses a printing process called four-color plate printing to combine four basic colors of different intensities, namely magenta ("M"), yellow ("Y"), and cyan (" C") and black ("K") are mixed. In fact, due to the frequent need for manual intervention, it is often boring to accurately print color images that satisfy the customer, with many problems, and a waste of time. For example, the traditional fo...
