Embodiment 1

[0054] In this embodiment, a multi-dimensional lookup table from LAB to CMYK is established through the LAB calculated value of the color target image and the measured value of LAB printing. Color accuracy requirements between different devices. At the same time, the original color target image is processed and printed on the basis of the multidimensional lookup table, the color data of the printed image is compared with the color data of the original color target image to form a color difference value, and the multidimensional lookup table generated is repeatedly corrected by using the color difference value , until the color difference value meets the requirements. Since the actual printed color data is introduced into the correction process for cyclic correction, and the cycle is terminated when the color difference meets the requirements, the multi-dimensional lookup table after correction accurately reflects the corresponding relationship between the target color gamut an...

Abstract

The invention discloses a printer color cycle correction method, device and equipment and a storage medium, and relates to the field of printer color tubes. The printer color cycle correction method comprises the following steps: generating an original color target image; obtaining an LAB calculation value and an LAB printing measurement value; generating a multi-dimensional lookup table; correcting multi-dimensional lookup tables. The printer color cycle correction device comprises an image generation module, a numerical value acquisition module, a multi-dimensional lookup table production module and a multi-dimensional lookup table correction module. The graph printer color cycle correction apparatus includes a processor, a memory, and computer program instructions stored in the memory.Computer program instructions are stored on the storage medium. The printer color cycle correction method, device and equipment and the storage medium are used for solving the technical problems thatin an existing color difference management technology, the color conversion precision is low, and a printer cannot restore the color effect of an original image.

Description

technical field [0001] The invention relates to the field of printer color tubes, in particular to a printer color cycle correction method, device, equipment and storage medium. Background technique [0002] With the development of digital printing, everyone has higher and higher requirements for color management, which controls the best color effect that the printer can display. At present, color management is mainly divided into three steps: equipment calibration, equipment characteristics, and color conversion. Equipment calibration is often called "linearization" calibration, which can effectively control the output of various types of ink characteristics into linear output, and can ensure The gray balance of data superposition can improve the color effect to a certain extent; the device characteristics mainly refer to printing a series of color block images and scanning to obtain the measurement data of the color block images under the premise that the device calibratio...
