Digital printing method of leather

Abstract

The invention relates to a digital printing method of leather, comprising the following steps of: (1) designing: firstly using a computer to design needed patterns, and adjusting luster and color to the needed requirements; (2) typesetting: determining corresponding width on the typesetting format of the computer according to the width specification of the leather needing to be printed, moving the patterns needing to be printed to a print typesetting program, and determining the quantity and the typesetting of the printing patterns according to the size of the width of the leather; (3) input: inputting the program with the typeset printing into the computer for controlling an inkjet machine; (4) painting: putting the fabrics needing to be printed on the inkjet machine, and instructing the inkjet machine to complete painting of the above patterns; or putting the fabrics needing to be printed on a UV painting machine, and instructing the UV painting machine to complete painting of the above patterns. The patterns are directly printed on the leather, therefore, the digital printing method of leather avoids the influence of transfer paper, transfer films and transfer film prints on the aspects of vision and touch and has good printing effect.

Description

(1) Technical field [0001] The invention relates to a digital printing method for leather. (2) Background technology [0002] The existing leather printing process can only use transfer printing, screen printing or roller printing, and transfer printing often has a great impact on the hand because of the use of transfer paper or transfer film, and has a great impact on the leather in terms of visual perception. Due to the existence of transfer paper or transfer film on the surface, it is not easy to be accepted by customers, so it is difficult to fully promote it in the market. Although roller printing is superior to transfer printing in terms of feel and visual senses, it is limited by the process (the process can only print the pattern before it is sold in the tannery or artificial leather factory), plus the pattern For leather goods manufacturers, the lack of individuality and choice, the pattern is not easy to cut and the reasonable positioning of the pieces and other f...

Problems solved by technology

[0002] The existing leather printing process can only use transfer printing, screen printing or roller printing, and transfer printing often has a great impact on the hand because of the use of transfer paper or transfer film, and has a great impact on the leather in terms of visual perception. Due to the existence of transfer paper or transfer film on the surface, it is not easy to be accepted by customers, so it is difficult to fully promote it in the market

Although roller printing is superior to transfer printing in terms of feel and visual senses, it is limited by the process (the process can only print the pattern before it is sold in the tannery or artificial leather factory), plus the pattern For leather goods manufacturers, there is a lack of individuality and choice, the pattern is not easy to cut and the reasonable positioning of the pieces and other factors cannot really meet the needs of customers.

Screen printing is limited by the process, whether it is in pattern design, plate making, color printing process and color matching, as well as the influence of leather grain texture on its squeegee process, the richness of hand feeling and color There are many defects such as the appearance of the printed pattern and the appearance of the printed pattern caused by the uneven color of the paint or dye, etc., which seriously affect the market acceptance and survival and development space of the process.
