Description

Technical Field

[0001] This invention relates to a color correction method, specifically to a color correction method and system for printed and dyed textiles. Background Technology

[0002] Color is a crucial factor influencing the appearance and style of textiles. Appropriate colors and patterns can fully showcase the style of textiles and attract consumers. The colors on textiles are mainly achieved through printing and dyeing processes, which usually require the blending of two or more dyes. Before mass production, small-scale samples are generally required to obtain a formula that meets the standard color requirements of the customer.

[0003] Traditional methods rely on the practical experience and visual observation of skilled workers for color matching. This often results in a low success rate, requiring multiple rounds of color adjustments to achieve a satisfactory formula, which is time-consuming and inefficient. In recent years, with the rapid development of computer technology, computer-aided color matching systems have been gradually applied in dyeing and printing enterprises. Formulas obtained through computer-aided color matching systems have a significantly higher accuracy rate than manual color matching, reducing the number of adjustments and sampling steps. However, the accuracy of computer-aided color matching depends primarily on the accuracy of the underlying database and algorithm. In practical applications, the properties of textiles, dyeing processes, interactions between dyes, and the difference between the ideal conditions assumed in the algorithm and actual conditions all affect the accuracy of the color matching results. Therefore, the success rate of a single color matching attempt is not high, and color adjustments are often necessary to obtain a satisfactory formula. Thus, improving color adjustment effects, reducing sampling steps, and increasing efficiency are important issues that the industry needs to address.

[0004] However, current research by scholars and practitioners in related fields mainly focuses on color matching, with relatively little research on color correction. Existing color correction methods primarily use the ratio method to correct reflectance or tristimulus values, and then re-match the colors. In recent years, there has also been research on the difference method. In the implementation of the difference method, after calculating the reflectance difference between the sample color and the standard color, the reflectance spectrum of the standard color is corrected through the difference, and a new color correction formula is obtained through spectral color matching calculations, which has some reference value. However, the reflectance spectrum usually contains reflectance values ​​corresponding to 31-36 points. Continuously correcting the reflectance spectrum can easily increase errors, affecting the color correction effect. Furthermore, color correction is usually difficult to achieve successfully in one attempt, requiring 1-3 more attempts, while existing color correction methods only consider the correction of a single difference, which is not comprehensive enough. Finally, both the ratio method and the difference method can only improve the color correction effect under certain conditions, and have certain limitations. Summary of the Invention

[0005] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects.
