Printing and gilding registration method in process of gilding before printing

Abstract

The invention discloses a printing and gilding registration method in a process of gilding before printing, which comprises the following steps: 1, manufacturing a special positioning film for gilding positioning: manufacturing positioning documents and outputting at least two makeup films and a positioning film; 2, preparing a gilding plate into a conjoined plate: manufacturing the basic documents of the copper gilding plate, and preparing the gilding plate; 3, carrying out para-position on the positioning film by the gilding plate: calibrating the position of the gilding plate, and registering the gilding plate to the positioning film; and 4, printing a corrected plate. Compared with the traditional thermoprint process, the method disclosed by the invention has the advantages that: 1, before gilding, no offset printer is require for printing positioning paper for gilding the corrected plate, therefore, a good deal of offset print resources can be saved, and the production cost can be saved; and 2, in the process of printing a corrected plate after gilding, the phenomenon that the gilding registration is not accurate does not exist, and the modification on a printing plate caused by that the gilding registration is not accurate does not occur, thereby greatly improving the accuracy of registration, and saving plenty of time required by changing the position of the gilding plate for many times; and meanwhile, the rejection ratio of the production process is low.

Description

[0001] technical field [0002] The invention relates to the technical field of printing and decoration technology, in particular to a method for registering printing and bronzing, in particular to a process of stamping first and then printing, that is, a process of stamping first and then printing. Background technique [0003] Hot stamping has the advantages of clear and beautiful patterns, bright and eye-catching colors, wear resistance and weather resistance. On the printed cigarette labels, the application of bronzing technology accounts for more than 85%. And bronzing on graphic design can play a finishing touch and highlight the design theme, especially for trademarks and registered names, the effect is more significant.

Problems solved by technology

In the traditional hot stamping technology, before the hot stamping, it is necessary to separately arrange the offset printing machine to print the positioning paper (about 100 sheets) for the hot stamping proofreading, which seriously wastes the resources of the offset printing equipment and affects its effective use and the continuity of the production plan

[0004] In the process of printing and proofreading after hot stamping, it is often necessary to change the graphic position of the printed version, and it needs to be changed 2 to 3 times or more to basically register the hot stamping position, and it is difficult to achieve strict registration effect, leading to a high scrap rate

And each revision takes an average of 2 hours, which seriously wastes equipment, human resources and time costs, and seriously affects the arrangement and progress of production planning, increasing production costs
