Embodiment Construction

[0091] The present invention will be further described in detail in conjunction with the accompanying drawings: the present invention is designed with CMYKRGB halftone percentage dots, referring to the WKTone theory, according to the preset pattern, a series of alternate, close-to-overprint, with a positioning sequence, to provide grayscale vision Compare with reference. The "K" grayscale is the primary inspection reference as a starting point and serves as a target for "C, M, Y, CR, MG, YB" to blend into a neutral gray. This reference tool has no length limit, it can cover the entire width of the print, without interrupting any color information, to make effective correction functions. 100% monochrome and preset percentage monochrome dots CMYRGBK can also be integrated, replacing a few "K" grayscales, to provide the operator with additional information on dot gain.

[0092] WKTone (HiFi) has a unique color balance function, without overloading information, designs patterns a...

Abstract

The invention provides a multiple primitive color printing color value correcting method. In the method, a color value zone is set on a printing material, a secondary primitive color generated by combining main primitive colors and corresponding primitive colors are overprinted according to a predetermined percentage to form a neutral grey scale of combination of the main primitive colors and the secondary primitive color; in a set color value zone, a black 'K' halftone is used as reference to compare a monochromatic grey scale and the neutral grey scale so as to correct the color value and control color changes. By utilizing WKTone neutral grey balance principle and adopting a visual technology, an operator can accurately control color ink usage comparison, and color reading equipment can read color value changes to correct colors in real time. The method can be used for surmounting three-color sampling, and used for large-scale production and printing.

Description

technical field [0001] The invention relates to a printing quality control method, in particular to a multi-primary color printing quality control method. Background technique [0002] Color theory is explained clearly in the teaching textbooks of general elementary school level. The color circle is a commonly used teaching tool to understand color theory. Specifically, the natural color spectrum can be combined by six colors of magenta (M), red (R), yellow (Y), green (G), cyan (C), and blue (B). The main primary colors of magenta, yellow, and cyan are formed by the subtractive color method, which is suitable for all kinds of color inks, paints and other products; the secondary primary colors of red, green, and blue are formed by the additive color method, which is suitable for use in electronic optics Applied in TVs, scanners and other products. [0003] Based on the above color theory, scientists use filter lenses to analyze the main primary colors of magenta, yellow, a...
