Eight-color digital textile printing method

Abstract

The invention discloses an eight-color digital textile printing method. The method comprises the following steps of: 1, separating needed printing colors by using a computer; 2, arranging two sets of ink of eight primary colors in total in eight ink cartridges of a digital textile printing machine, wherein the eight primary colors are respectively C, M, Y, K, C1, M1, Y1 and K1 respectively representing cyan, red, yellow, black, light cyan (cerulean), pink, orange yellow and gray and can be used separately, the first four colors are deep cyan, deep red with yellow light, light yellow, pure dark, the last four colors are cerulean, deep pink belonging to red with purple light, orange yellow and gray, each of the eight ink cartridges is equipped with a sensitive printing ink heads so that every ink cartridge can be controlled by the computer freely, two or more than two of the eight primary colors can be blended mixed freely as required and mixed colors are printed on a pretreated textile product under control of the computer to form lines or patterns; 3, washing the printed textile product with water to remove surface colors from the textile product and then drying the textile product to obtain a finished product. Through adoption of the method disclosed by the invention, the eight colors can be matched and mixed freely and the mixed colors are improved in both color light and color match error so that required colors can be printed on a textile product.

Description

technical field [0001] The invention relates to an eight-color digital printing method. Background technique [0002] With the development of the economy and the progress of the society, people's requirements for the personalization and artistry of the living environment and textile printing continue to increase; while the traditional printing speed is slow, the cost of small batch production is high, and environmental pollution and other factors cannot meet the needs of modern people.

Problems solved by technology

However, although digital printing has many commercial application advantages in the printing field, the existing color brightness and fastness cannot completely control the market, and only a small number of high-end market customers can only be used.

Traditional digital printing (DTP) uses the first four colors of C, M, Y, K, LC, LM, LY, LK (cyan, magenta, yellow, black, light cyan, light magenta, light yellow, light black) One-color or eight-color inks are made according to the printing method, and the colors cannot be freely combined, which has certain limitations. The mixed colors have the disadvantages of not being bright, and a lot of color errors. It cannot mix and print the required colors. If Mass production is required, which may cause a big difference in color from traditional printing, and even result in a large claim loss
