Printing method of combining conventional printing with digital printing

Abstract

The invention relates to a printing method of combining conventional printing with digital printing. At present, no printing method is capable of really and effectively combining conventional printing with digital printing. The printing method sequentially comprises the following steps of:1. decomposing a pattern, namely, decomposing a pattern needing being printed into a conventional printing pattern and a digital printing pattern; 2. mixing size and making plate, namely, carrying out dye blending and making a digital printing screen; 3. carrying out screen printing, namely, carrying out conventional printing and digital printing pretreatment; 4. carrying out digital printing, namely, carrying out digital jet printing on a printing medium by adopting a digital jet printing system with a pre-detection device according to the digital printing pattern, determining a digital printing position on the printing medium, printing the digital printing pattern on the printing medium to ensure that the digital printing pattern is coincident with the conventional printing pattern; and 5. carrying out post-treatment to prepare a finished product. The printing method is good in printing effect and low in production cost, and is capable of really and effectively combining the conventional printing with the digital printing.

Description

technical field [0001] The invention relates to a printing method, in particular to a printing method combining traditional printing and digital printing. Background technique [0002] Currently commonly used printing methods include traditional printing methods and digital printing methods, wherein, traditional printing methods usually include the following steps: 1. Preparation steps, including mixing and preparing screens. The number of sets of screens is equal to the number of screens; 2. The printing step includes flat screen printing and rotary screen printing; 3. The steaming step is to fix the color; 4. The washing and setting steps. Traditional printing has the following advantages: 1. There are many colors and bright patterns, and special colors such as gold powder and silver powder can be printed, and the color gamut is large; 2. The cost of printing color blocks is low. The disadvantages of the traditional printing method are: when the color of the pattern is ma...

Problems solved by technology

The disadvantages of the traditional printing method are: when the pattern has many colors, the effect is poor, and the richness of the pattern is not enough

The disadvantages of the digital printing method are: 1. The color is made of mixed colors, the vividness is reduced, the gray scale is enhanced, the pattern is not bright enough, and the color gamut is small; 2. It is difficult to print special colors, such as gold powder, silver powder and other particle sizes. big color

[0004] Now there is also a printing process that combines traditional printing and digital printing. For example, in the Chinese patent whose publication date is August 1, 2012 and whose publication number is CN102619114A, a new printing process combining digital printing technology is disclosed. The printing process includes The following processing steps: (1) Pre-treatment: pre-baking and pre-setting the white blank of the fabric, and preparing printing paste; (2) Printing: using the inkjet screen making mechanism 8 color separation screens, on the traditional flat screen printing machine. printing paste on the pre-treated fabric; (3) steaming: using a steaming machine to steam the printed fabric; (4) washing: using a washing machine to wash the steamed fabric; it is characterized in that: Before the traditional flat screen printing machine prints the pre-treated fabric, the digital printing process is used to print the initial sample on the fabric, that is, the digital printing technology is combined in the traditional printing process, but the printing process The design is not reasonable enough. First, the digital printing process is used to print the initial sample on the fabric, and then the traditional flat screen is used for printing. In this process, there will be wrinkles in the printing medium, which makes it difficult for the pattern printed by the traditional printing method to be accurate, effective and accurate. The patterns printed by the digital printing process are consistent, that is to say, it is actually difficult for the printing process to truly and effectively combine traditional printing and digital printing. There are still insurmountable technical defects in the combination of traditional printing and digital printing, resulting The production efficiency of the printing process is low, the printing effect is poor, and the defective rate is high, which greatly reduces the quality of the product.

[0005] To sum up, at present, there is no printing method with reasonable design, good printing effect, low production cost, high quality of printed products, which can truly and effectively combine traditional printing and digital printing.
