Method for applying alumite in cold stamping process

Abstract

The invention discloses a method for applying alumite in a cold stamping process. The method comprises the following steps that a plurality of products are subjected to integral makeup, so that each product comprises at least one cold stamping content area; after the integral makeup is completed, multiple cold stamping content areas are located in the middle of the width direction of a page, the total width of the multiple cold stamping content areas is minimum, and the minimum width of the alumite is determined according to the distance between the side lines on the two sides of the cold stamping content areas; cold stamping detection lines are arranged on the seam side and the page tail side, and whether offset and stamping missing exist in the cold stamping content areas is detected in an auxiliary mode through the cold stamping detection lines; and the alumite is selected or cut according to the determined width of the alumite, and the selected or cut alumite is used for cold stamping. According to the method, the minimum width of the alumite is determined according to the distance between the two side lines of the cold stamping content areas, and the cold stamping detection lines are arranged to assist in detecting whether the cold stamping content areas have the offset and stamping missing, so that the cold stamping process is ensured to meet the requirements, and the dosage of the alumite can be reduced on the premise of ensuring the cold stamping effect.

Description

technical field [0001] The invention relates to the technical field of cold perm printing, in particular to a method for applying anodized aluminum in the cold perm process. Background technique [0002] The anodized aluminum used in the cold stamping process is a special special anodized aluminum, the back of which is not glued, and the adhesive is directly coated on the substrate through the printing plate during printing. When the film surface is transferred, the anodized aluminum is the same as the adhesive. Contact, under the joint action of adhesive, pressure and UV drying, anodized aluminum is also attached to the surface of the printed matter. Since the transfer is on the upper surface of the substrate, the firmness is lacking, so it must be protected. Gloss or film on the surface of printed matter to protect the content of cold stamping anodized aluminum hot stamping. [0003] The cold stamping process breaks the traditional hot stamping process that relies on hot...

Problems solved by technology

[0004] In the existing cold perm process, in order to ensure the effect of cold perm, the width of the anodized aluminum is generally set to be greater than the width of the distance between the side lines on both sides of the die-cutting auxiliary line. The waste of aluminum, therefore, how to reduce the amount of anodized aluminum under the premise of ensuring the effect of cold perm is a technical problem to be solved urgently

The Chinese patent with application publication number CN 102248762A discloses a sheet-fed cold stamping printing equipment and its working method. An independent cold stamping unit is used to directly cold stamp a sheet of paper, which can save the amount of electrochemical aluminum, but it is not suitable for continuous printing. The efficiency of the printing process is low, and the relationship between the anodized aluminum and the cold stamping content area is not considered, and the consumption of anodized aluminum is not fundamentally saved; the Chinese patent application publication number of CN 103264575 A discloses a method for saving cold ironing Foil cold stamping device and method, when there is no need to transfer the cold stamping foil on the paper, the transfer of the embossed part of the cold stamping foil is stopped, and the paper feeding speed, foil feeding speed and foil receiving speed will not be affected, so as to save the cold stamping foil, Similarly, this scheme does not take into account the relationship between the anodized aluminum and the cold perm content area, and does not fundamentally save the amount of anodized aluminum
