Wallpaper printing process without limitation of length of unit pattern

Abstract

The invention relates to a wallpaper printing process and particularly relates to a wallpaper printing process without the limitation of the length of a unit pattern. The wallpaper printing process is finished by adopting multi-section rotary screen printing equipment. Each piece of multi-section rotary screen printing equipment comprises a plurality of rotary screen printing rollers and an alignment control device; a pattern of wallpaper is divided into at least two sections; each section of the pattern is finished by one corresponding rotary screen printing screen plate; one section of the pattern is printed respectively by at least two rotary screen printing screen plates; then the two sections of the patterns are connected to form a complete wallpaper pattern. According to the wallpaper printing process, the large-size wallpaper without the limitation of the perimeter can be produced and the patterns of the wallpaper are diversified and are dynamic; the printed wallpaper has an embossment stereoscopic impression; the production process is suitable for industrial production and low in production cost; the quality is guaranteed effectively.

Description

technical field [0001] The invention relates to a wallpaper printing process, in particular to a wallpaper printing process with unlimited unit pattern length. Background technique [0002] Wallpaper, also known as wallpaper, is an important part of modern interior decoration materials and one of the main decoration materials for interior wall surfaces. Because wallpaper has the characteristics of various colors, rich patterns, safety and environmental protection, convenient construction, and reasonable price, it is used more and more widely. The unit length of the current wallpaper printing pattern is determined by the diameter of the rotary screen printing screen. The diameter is limited, so the basic unit length of the wallpaper printing patterns currently used by rotary screen printing is about 640mm, the longest not exceeding 1018mm, and the pattern of the wallpaper is fixed, and the pattern of each wallpaper can only be displayed repeatedly, and the style is relative...

AI Technical Summary

Problems solved by technology

According to the existing wallpaper printing technology, if people want to get better results, people generally change the color of the pattern, and it is impossible to make a breakthrough in the length and diversity of the pattern, because it is impossible to produce large-scale pattern wallpaper with the existing printing process of

However, with the continuous development of the social economy and the continuous improvement of people's living standards, a large number of hotels and high-end residences have emerged, and people have higher and higher requirements for interior decoration, especially in high-end hotels and high-end villas, the walls of the hall are very high. , hoping to use a complete patterned wallpaper for decoration, such as Dunhuang murals and other large-scale patterns with three-dimensional effects, according to the existing printing technology can not be realized with a complete wallpaper, the current method is to The wallpaper is divided into several pieces, which are printed on multiple wallpapers, and are spliced ​​and combined during installation. However, the effect of this spliced ​​pattern is not good, and the splicing seam is easy to see. higher

Or use spray painting or hand-painting to make large-scale murals, but the patterns made by spray-painting methods lack three-dimensionality, and cannot achieve the three-dimensional effects of various reliefs on wallpaper, while hand-painted murals require a large amount of engineering, high cost, and cannot be repeated. Production, the quality cannot be guaranteed, and the characteristics of durability, easy replacement and mass production of wallpaper are not enough.
