When it comes to color management, its presence can be seen in various controls of pre-press software and back-end printing hardware, as well as in the most front-end processes such as the delivery of printing originals, the selection of post-press materials and consumables, and the inspection of printed products.
The essence of printing lies in the faithful and reliable reproduction of graphics and text on various substrates. The key to achieving this goal lies in efficient color management, converting the graphic and text data unrelated to the front-end devices into print data related to the output devices through color management, so that it can be correctly presented on the substrate. Its significance lies in serving as the back-end technical support for data collection, conversion and presentation. Printing without color management cannot be called printing manufacturing.
The demand for color management in printing quality control is consistent throughout, and the involved elements are reflected in four aspects: equipment calibration, equipment characterization, color matching, and closed-loop control. Among them, closed-loop color management integrates the collection, feedback and data optimization of printing color data seamlessly, achieving comprehensive printing quality control without any blind spots.
The WYSIWYG in printing is mainly reflected in the consistency of color, which is manifested as the restoration of color consistency under different printing conditions. Reasonable regulation of the four key elements of color management can effectively control the color quality of printed products under different printing conditions within a reasonable range. Among them, the core control indicator is the precise replication and mapping of the grey balance. The core of quality control in a complete printing system is the regulation of the gray balance of colors. Through the above control methods, the gray balance of the current system can be accurately reproduced, thereby ensuring the correct color restoration of the entire system. It can be seen from this that ensuring the consistency of printing colors will be simplified to the reproduction and mapping accuracy of gray balance under different printing conditions. The higher the accuracy, the higher the consistency.
Founder Ruicai Color Management System
Taking the Founder Yinjie color digital inkjet printer and the Founder Ruicai process-based color management software as examples, after adjusting the hardware status of the equipment, the inkjet equipment calibration is carried out first, and standardized regulation is made by referring to the chromaticity and density of each stage of the target substrate. Then, in the stage of equipment characteristic data collection, the carrying capacity of the maximum ink volume of the substrate is dynamically calculated in combination with intelligence

The color separation algorithm generates characteristic data. In the subsequent color matching stage, the program precisely locates the black and white fields of the device‘s color gamut, and uses the gray-axis compensation technology and chroma micro-control technology to achieve stable and efficient color gamut and gray-axis mapping between the target color gamut and the device‘s color gamut. Finally, based on the color mapping results, the software system automatically feeds back the chromaticity values measured at each node within the device‘s color gamut to the Ruicai software for color difference comparison with the target color. Corresponding corrections are made according to the color difference values before outputting, thereby ensuring that the output color of the inkjet device is as close as possible to the target color. This closed loop operates in a continuous and uninterrupted mode during production. By constantly correcting the color gamut mapping error, it achieves a high color matching degree and color output stability between the inkjet device and the target device, perfectly realizing the precise color restoration of the color seen by the target device in the output of the inkjet device.
Through the production practices of multiple customers, it has been verified that this software and hardware system not only achieves ISO
The high-standard color consistency simulation also meets the color matching requirements of customers under non-standard printing methods, truly interpreting the printing concept of "what you see is what you get".
