Embodiment Construction
[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the following descriptions are only specific illustrations of the embodiments of the present invention, and should not limit the protection scope of the present invention.
[0032] The invention provides a color detection method and device for laser printing materials. Its purpose is to establish a color database through the principle of chromatic light refraction and diffuse reflection, and reduce the problems caused by inexperienced operators, sensitivity to changes in environmental light sources, and visual fatigue of the human eye. In addition to the unstable factors of color difference detection and the low pass rate of instrument detection in the existing technology, data collection, st...

The invention discloses a method and device for detecting the color of a laser printing material, and the method comprises the steps: obtaining an incoming material Lab value of a printing material which is not printed through a spectrophotometer, and recording the incoming material Lab value in a color evaluation system, so as to build an incoming material color database; obtaining a printing Lab value of the printing material after printing, and recording the printing Lab value in the color evaluation system, so as to build a printing color database; carrying out the incoming material color detection of the printing material which is not printed according to the incoming material color database, and carrying out the product color detection of the printing material according to the printing color database after printing. The beneficial effects of the invention are that the method irons out a technical defect in the experience-based judgment of a laser printing material; the method monitors the dynamic printing color in real time, completes the control of the color difference of a laser-type printing product, and avoids the product quality complaint and scrap caused by the color difference; the method digitalizes the color information of the laser-type printing product, and achieves the digitalized management of the color and quality of finished products.
Description
technical field [0001] The invention relates to the technical field of printing color management, in particular to a color detection method and device for laser printing materials. Background technique [0002] For printing consumables with laser effects, the color difference of incoming materials and online printing will play a decisive role in the quality of the product. However, due to the particularity of the surface structure of laser materials, on the one hand, its incoming material color difference and online printing color difference have not been able to obtain accurate data through instrument measurement. On the other hand, due to the strong adaptability of the human eye to color and the interference of colored light in the laser effect, the judgment of the printing color difference of the laser material often has insufficient experience of the operator, changes in the light source environment and visual Fatigue and other problems, the above problems have become t...
