Problems solved by technology

[0002] At present, in the printing and foaming of pure paper and non-woven paper in wallpaper products, only one corrosion depth is made on one printing plate. It has a more three-dimensional effect than simple printing, but the entire pattern has only one height, and the effect is very single. There is no glue surface wallpaper after embossing. The effect is rich; if a printing plate can produce different corrosion depths according to different pattern characteristics, In this way, different heights can be produced after printing and foaming, and the effect of pure paper and non-woven paper after foaming can be close to the effect of embossed wallpaper on the rubber surface. It has the characteristics of rich layers and strong three-dimensional effect

Embodiment Construction

[0011] Mother roll plate of the present invention is long 600 millimeters, and diameter is 233.50 millimeters, and mother roller has plated bottom nickel, and the thickness of nickel is 1 silk, and the manufacture method of the present invention is further described below.

[0012] Machining: Machining length of mother roll is 750 mm, diameter is 233.50 mm.

[0013] Copper plating: The thickness of copper plating on one side of the mother roller is 17 wires.

[0014] Grinding: Grinding the copper layer to a plate roll diameter of 233.84 mm, and ensuring a smooth plate surface.

[0015] Manuscript production: Use computer software to make patterns according to customer requirements. During the pattern making process, more points and lines must be used, and the interval between points and lines should be properly controlled to avoid the gap between points and lines being too small. , so that the dots and lines are connected together after the printing is foamed, and there is no...

Abstract

The invention relates to a printing roller manufacturing technology, and concretely relates to a manufacturing process for a printing roller multi-depth foaming forme. The process comprises steps of mechanical processing, nickel plating, grinding, manuscript manufacturing, glue spraying, laser engraving, and corroding. The process is characterized in that: secondary glue spraying processing, secondary laser engraving processing, secondary corrosion processing and chrome plating processing are carried out after the corrosion step. Compared with the prior art, different patterns can have different depths on the printing roller as needed in the invention, so embossing effects on pure raw paper and nonwoven paper which can reach embossing effects on rubber surface wallpaper have rich stereoscopic and layered sense.

Description

[technical field] [0001] The invention relates to a printing and dyeing roll making technology, in particular to a method for manufacturing a multi-depth foam plate for printing and dyeing rolls. [Background technique] [0002] At present, in the printing and foaming of pure paper and non-woven paper in wallpaper products, only one corrosion depth is made on one printing plate. It has a more three-dimensional effect than simple printing, but the entire pattern has only one height, and the effect is very single. There is no glue surface wallpaper after embossing. The effect is rich; if a printing plate can produce different corrosion depths according to different pattern characteristics, In this way, different heights can be produced after printing and foaming, and the effect of pure paper and non-woven paper after foaming can be close to the effect of embossed wallpaper on the rubber surface, with the characteristics of rich layers and strong three-dimensional effect.
