First of all, color box printing needs to perform equipment calibration and system calibration. These equipment include scanning equipment, display equipment, output equipment and proofing equipment. These equipment must undergo strict professional calibration. In addition, there must be a relatively complete set of equipment among these equipment. These are the basis for color correction.
Then, before the color box printing correction, the level correction should be carried out. Because according to the color rendering mechanism, the color is presented on the basis of neutral gray level, so the level should be corrected before the color correction, otherwise, after the color correction is completed, the color will change when the level is corrected.
Secondly, the quality of color box printing paper is also very important. When printing color box, try to choose film-coated paper packaging. If ordinary paper is used, it is more reasonable to choose a corrugated carton under normal circumstances.
