Embodiment 1

[0049] A method for printing four primary colors on towels, the steps are as follows:

[0050] 1) For the production of plate-making manuscripts, firstly, the images of hand-carved or mechanically engraved manuscripts are made into black-and-white manuscript negatives, and then made into photosensitive printing masters, which are photosensitive copies, and then printed in black and white by printers through laser phototypesetting draft; the main function is to make a photosensitive printing template. Therefore, the plate-making manuscript must be drawn on a light-transmitting substrate, and its image is an opaque ink layer (black or red). The shading density is a key indicator to determine the quality of plate-making manuscripts;

[0051]2), the production of the color separation image manuscript, the color separation image adopts spot color separation and primary color separation. The color is formed into a color image through chromatographic printing, and the design and com...

Embodiment 2

[0097] According to the mass ratio, the seaweed paste is composed of 320-380 parts of water, 3.2-3.8 parts of sodium hexametaphosphate, and 10.5-11.7 parts of sodium alginate after stirring evenly, and then adding water to the total composition of 420-480 parts;

[0098] Ordinary color paste consists of 0.2-0.3 parts of seaweed paste, 0.04-0.05 parts of thickener FS-86, 1-13 parts of dyes, 0.005-0.01 parts of urea, 0.001-0.002 parts of resist salt S, 0.01-0.02 parts of 80-90 ℃ hot water, 0.002-0.003 part of sodium bicarbonate, 0.01-0.02 part of cold water, and then add hydration to synthesize 10 parts in total, and other steps are the same as in Example 1.

[0099] This color paste is suitable for the printing of products with a square meter weight of less than 300 grams and medium and light color patterns.

Embodiment 3

[0101]Beating: The printing of fabrics is mainly printed with reactive dyes, which mainly use the mixed color paste of active thickener FS-86 and seaweed pulp to prepare the color paste:

[0102] According to the mass ratio, the seaweed paste is composed of 330-370 parts of water, 3.4-3.6 parts of sodium hexametaphosphate, and 10.8-11.0 parts of sodium alginate after stirring evenly, and then adding water to form a total of 430-470 parts;

[0103] Black, bright red, and navy blue pastes consist of 0.05-0.11 parts of seaweed paste, 0.043-0.046 parts of thickener FS-86, 1-10 parts of dyes, 0.005-0.01 parts of urea, 0.001-0.002 parts of resist salt S, 0.01-0.02 parts Part 80-90 ℃ of hot water, 0.002-0.003 part of baking soda, 0.01-0.02 part of cold water, add hydration to synthesize 10 parts of total amount, other steps are with embodiment 1.

[0104] This color paste is suitable for the printing of products with a square meter weight of more than 300 grams and medium-dark patter...

Abstract

This invention discloses a method for printing on towels with four primary colors including: preparing draft of plate making and color image draft and color plate-making, applying reticles as the basis of the location of multi-chromatic color-splitting plates, drafting digitalized manuscripts and drafting laser makeup output screen plates, in which, the printing technology includes beating slurries, selection of printing device and its technics including: first of all printing plates of small flowers, then printing rough block areas and pringing large areas finally, printing tint first and dark colors later, printing overlapped colors according to the result and printing screen plates of same kind of colors separately, fine lines are printed after the large areas and dope lines are printedon the first edition and flowers are printed according to the result, which combines black and white and color-splitted images to get a simple printing method.

Description

technical field [0001] The invention relates to a textile printing method, and is especially suitable for printing four primary colors on towels. Background technique [0002] Any color in nature is composed of three primary colors, so in theory, three color plates of cyan, magenta, and yellow can be used to print a realistic restored image, but due to various factors, it is difficult to achieve the three primary colors. That's it. Therefore, four-color printing is usually used in printing practice, that is, three primary colors plus black. In recent years, in order to restore colors more realistically in the world, six-color printing and seven-color printing have been developed on the basis of four-color printing. The principle is to combine the composite colors of orange, purple, green, etc. Separated to reduce grayscale for high-fidelity printing. In order to distinguish it from spot color printing, we usually refer to the reduction printing of natural color patterns t...
