Surface gradual change printing technology and product thereof

Abstract

The invention discloses a surface gradual change printing technology. The technology mainly comprises the following steps that firstly, printing ink is diluted, and printing ink of at least two different colors is taken to be diluted; secondly, screen inlet mixing is carried out, the diluted printing ink of the at least two different colors is guided in a blank screen printing plate and is linearly arranged according to the gradual change sequence, and a stacking layer of overlapped printing ink of two different colors is formed between adjacent printing ink of every two different colors; thirdly, stacking layer color matching is carried out, and complete mixing and color matching are carried out on the printing ink of the stacking layer through a silica gel scrapper till colors are mixed evenly; fourthly, one-time printing is carried out, a printed material is printed with a gradual change printing ink layer through the blank screen printing plate and the printing ink with even color matching on the blank screen printing plate. The non-screen-point gradual change silk-screen printing is adopted, the manufacturing procedure is simple, convenient and effective, and the product has very even transition and natural non-screen-point gradual change effects.

Description

technical field [0001] The invention relates to a surface gradient printing process and its products. Background technique [0002] Nowadays, the decoration of various household appliances, electronic products, etc. on their surface shells has attracted more and more attention, and has become a very competitive factor in the market. At present, the decoration of the surface shell tends to form multi-color patterns or gradient patterns, and the effect of gradient colors is simple and elegant, which is more favored by consumers. At present, the methods of forming gradient effect on the surface are roughly divided into spraying and printing. Among them, the spraying method needs special spraying equipment to realize, and its cost is high, which is difficult for ordinary users to implement. The printing method adopts dot gradient screen printing. During printing, film sheet and screen printing are required. Gradient multi-color printing needs to be printed in multiple times, an...

Problems solved by technology

At present, the methods of forming gradient effects on the surface are roughly divided into spraying and printing. Among them, the spraying method requires special spraying equipment to realize, and its cost is high, which is difficult for ordinary users to implement.

The printing method adopts dot gradient screen printing. During printing, film sheet and screen printing are required. Gradient multi-color printing needs to be printed in multiple times, and drying process is required after each printing. The whole process It is extremely cumbersome and consumes a lot of manual operation and cost; and when the conventional dot screen printing is used in a large area or a large number, the dots often have dry screen problems, resulting in uneven gradient transitions, and the formed dot gradients can be seen visually. The transition is unnatural, which greatly affects the appearance of the gradient
