Problems solved by technology

[0002] The existing printing technology is screen printing spot color printing. Its steps include color separation, open circuit connection, black and white film making, stretching frame, photosensitive pattern making, color paste, scraping, steaming, washing, etc. Every time a color is printed, a black and white film must be produced first, and then a flower board and a color paste are made out of the film; the disadvantages are: 1) If a pattern has twenty colors, then twenty A black-and-white film, 20 flower plates, 20 color pastes, and at least 20 sets of printing machines, which consume a large amount of film, plate materials and paste, and require a long printing machine. It needs to be purchased from abroad and the cost is expensive, so the cost of printing is high; 2) It takes a long time to make plates and prepare color paste for spot color printing, and it takes a lot of time to print and align the printing process during the printing process, so the delivery The time limit is relatively long; 3) The color matching of each pattern, because of the different size of the color of the page, the amount of color paste required is also different, even experienced color matching workers may not be able to estimate accurately, and in order to ensure color consistency. It is necessary to overestimate and make more color pastes; in short, each color will have color paste left during use, and these color pastes are not easy to recycle because of special colors, but can only be dumped. As a result, dyes and pastes are not only wasted , and pollute the environment

Embodiment 1

[0016] Embodiment 1 In this embodiment, the printing method of four colors, one flower and multiple colors includes color separation, open circuit connection, making black and white film, stretching frame, photosensitive pattern making, color paste, scraping, steaming, washing steps, where:

[0017] 1) The process of making black and white film is: first carry out computer four-color separation, that is, through computer color separation software, the color of the design is divided into four colors: red, yellow, blue and black composed of dots; Set 30cm dot overlap on the left and right sides of the open circuit, and each monochrome film at the overlapping site is 30% of the non-overlapping site, which can be called "moiré extension open circuit method", and then output the film. The dot shape is hexagonal; the screening angles between two adjacent films are staggered by 15° or 30°, for example, the screening angle of yellow film is 0°, the screening angle of blue film is 15°,...

Embodiment 2

[0020] Embodiment 2 The difference between the printing method of this embodiment and Embodiment 1 is that the open-circuit connecting head forms a 10cm dot overlap on the left and right sides of the open circuit of the pattern; the screening precision is 65 lines / inch; the screening of the yellow film Angle 15°, blue film screening angle 45°, red film screening angle 75°, black film screening angle 90°; output film resolution is 600dpi; 300-mesh screen and screen frame are used for stretching Pre-bake at 60° for 30 minutes. On the gray cloth to be printed, use the above-mentioned four patterns and four color pastes to scrape print, add blue color paste to the blue pattern, add red color paste to the red pattern, and add yellow paste to the yellow pattern. Color paste, black color plate plus black color paste, after scraping and printing, you can get a color matching of this pattern such as Figure 5 ; Add blue color paste to the blue pattern, add yellow color paste to the re...

Embodiment 3

[0021] Embodiment 3 The printing method of this embodiment with four color separations, one flower and multiple colors is different from Embodiment 1 or 2 in that the open circuit connects the head to form a 20cm dot overlap on the left and right sides of the open circuit of the pattern; the screening accuracy is 70 Lines / inch; the screen angle of yellow film is 30°, the screen angle of blue film is 45°, the screen angle of red film is 60°, the screen angle of black film is 90°; the resolution of output film is 1200dpi; When using a 350-mesh screen, the screen frame is pre-baked at 70° for 30 minutes. On the gray cloth to be printed, use the above-mentioned four patterns and four color pastes to scrape print, add blue color paste to the blue pattern, add red color paste to the red pattern, and add yellow paste to the yellow pattern. Color paste, black color plate plus black color paste, after scraping and printing, you can get a color matching of this pattern such as Figure ...

Abstract

A method for printing multi-color pattern on fabric includes such steps as splitting the color of an original pattern into red, yellow, blue and black colors by computer, outputting their negative films, choosing screen, installing it on frame, exposing to preparing 4 plates, preparing the pigment slurries for said 4 colors, scrape printing four times, steaming, and water washing.

Description

technical field [0001] The invention relates to a fabric printing method, especially a method that only needs to make four patterns and prepare four color pastes, and print any pattern or multiple colors of the same pattern on the fabric through different combinations. Four-color printing method with one flower and multiple colors. Background technique [0002] The existing printing technology is screen printing spot color printing. Its steps include color separation, open circuit connection, black and white film making, stretching frame, photosensitive pattern making, color paste, scraping printing, steaming, washing, etc. Every time a color is printed, a black and white film must be produced first, and then a flower board and a color paste are made out of the film; the disadvantages are: 1) If a pattern has twenty colors, then twenty A black-and-white film, 20 flower plates, 20 kinds of color pastes, and at least 20 sets of printing machines, which consume a large amount ...
