[0003]
At present, digital printing color calibration cards at home and abroad generally use RGB or CMYK and other differential incremental methods to make them. The produced color calibration color cards generally have the problems of too large or too small colors, poor data accuracy, and weak guiding significance.

The invention provides a method for manufacturing a digital printing small-color-difference color correction color card. The method comprises the following steps of establishing a color characteristicfile of a jet printing machine; determining the basic color of the small-color-difference color correction card; determining the extended color of the small-color-difference color correction card; manufacturing a color correction card with small chromatic aberration; and carrying out jet printing output on the small-color-difference color correction color card. According to the invention, the defect of poor color guidance of the color card after the color correction card is manufactured by changing RGB components in the prior art is overcome; The problems that the color difference between adjacent colors is unclear, color lumps are inconvenient to retrieve, and the matching effect of the color card and the fabric is poor are solved, the color card is scientific and simple to manufacture,the color of the color lump is accurate, retrieval is convenient, the color correction precision is greatly improved, and the period and time of digital printing color correction are shortened.
Description
Technical field [0001] The invention relates to the technical field of digital printing, in particular to a method for producing a color card with small color difference for digital printing. Background technique [0002] As a reference for the color correction of digital printing and a tool for measuring color differences, the digital printing color correction card plays an extremely important role in the color correction of digital printing. How to quickly and accurately obtain the required color during the color correction process Accurate color component data has become an urgent bottleneck problem in the digital printing industry. [0003] At present, the domestic and foreign production of digital printing color calibration color cards generally uses RGB or CMYK methods to make the difference increment. The color calibration color cards produced generally have problems such as too large or too small colors, poor data accuracy, and weak guiding significance. Therefore, researc...
