AI Technical Summary
Technical Problem
When existing color spraying equipment sprays colors on the packaging materials of photovoltaic modules, the input color cannot be accurately presented, resulting in a large difference between the spray color and the input color.
Method used
By controlling the color spraying device to print gradient color block array maps on the packaging material, the peak of the total ink percentage is determined, and a color calibration printing profile is generated based on the peak and target color values for color calibration.
Benefits of technology
The color performance is achieved on the packaging material of the photovoltaic module that is closer to the image to be printed, reducing color differences and improving the accuracy of color spraying.

Abstract
The invention provides a color calibration method, device and system, and the method comprises the steps: controlling color spraying equipment to carry out the ink-jet printing of a gradient color block array diagram on a first printing medium based on the stepped total ink percentage of target ink; the stepped total ink percentage comprises a plurality of stepped increasing total ink percentage; the gradient color block array diagram comprises a hue gradient column which is subjected to ink-jet printing based on each total ink amount percentage; the gradient color block array diagram is used for determining the peak value of the total ink percentage; determining the color performance of each target color value on the packaging material based on the peak value and the plurality of target color values; generating a color calibration printing configuration file based on the peak value and the color performance of each target color value on the packaging material; the color calibration printing configuration file is used for performing color calibration when ink-jet printing is performed on the packaging material laminated with the photovoltaic module. Through the method, the color printed by the color spraying equipment is closer to the input color.
