Problems solved by technology

[0003] 1. The production efficiency is low. Even if it is produced by the most advanced automatic flat-press hot stamping machine in the world, the speed is only 3000 to 5000 prints per hour, and the equipment is expensive
However, if general equipment or even manual hot stamping equipment is used, the maximum speed is only 1200 to 3000 prints per hour, which greatly restricts the production capacity
[0004] 2. Raw materials are wasted, which increases the unit cost of bronzing and consumes a lot of power
Especially in the hot stamping text, lines, etc., there is more waste of anodized aluminum foil. In addition, because the hot stamping requires a temperature of 150-180°C, it takes a lot of power to work.

Embodiment Construction

[0009] The feature of the present invention is to use gravure printing equipment to realize the artistic effect of "bronzing". The specific process is: printing paper→combined gravure printing machine printing pictures and texts→setting and coating composite adhesives on bronzing parts→spraying metal powder→ Remove unnecessary metal powder → embossing.

[0010] The printing paper is printed by a combined gravure printing machine. This step is an ordinary gravure printing process. The innovation of the present invention is to transform the ordinary gravure printing machine, add a group of gravure rollers, change the printing process, and realize the hot stamping process. Coating composite adhesive for position positioning, and then spraying metal powder. At this time, the parts with composite adhesive, that is, the parts that are bronzing, are covered with metal powder. The other parts that do not need bronzing are not glued because there is no adhesive, and the metal powder is ...

Abstract

A located gilding technology for intaglio printing includes such steps as providing the paper to printed, intaglio printing, determining the position to be gilded, coating the composite adhesive on the position, spraying metallic powder, removing excessive metallic powder, and embossing.

Description

【Technical field】 [0001] The invention relates to a printing process technology, in particular to a gravure positioning bronzing process. 【Background technique】 [0002] At present, in order to enhance the artistic effect and make the theme prominent and eye-catching for packaging decoration or printed matter, some texts and patterns are often superimposed with hot stamping electrochemical aluminum foil process, which is commonly called "hot stamping". After the printed graphics are processed by this process, the surface is bright , Bright, played a role in highlighting the theme. The existing "hot stamping" process generally covers the hot stamping image with anodized aluminum foil, heats the hot stamped part with electric heating, and transfers the corresponding part of the anodized aluminum foil to the printed matter through printing plate embossing. This process has the following defects: [0003] 1. The production efficiency is low. Even if the world's most advanced au...
