Process for transfer printing of aluminized or laser patterns on plastic film

Abstract

The invention disclosed a process for transfer printing of aluminized or laser patterns on a plastic film, which comprises the following steps: a, pre-printing design: adding aluminized or laser patterns or logos to a layout pattern; b, plate making: mounting corresponding plate rollers respectively in accordance with the color of the layout pattern and the aluminized or laser patterns, and carving the corresponding patterns on the plate rollers; and c, simultaneously printing, sizing and affixing aluminized films or laser films: during printing, putting the plate roller caved with color patterns into an ink fountain filled with corresponding colors; putting the plate rollers carved the aluminized or laser patterns into the ink fountain filled with glue water, and colorizing the glue water at the same time for the convenience of tracking by a photoelectric eye during printing; arranging the ink fountain filled with the glue water at the backmost position for printing; and coating a silicone oil layer on guide rollers of a printing machine from a discharge port of a glue water printing machine set to a printing rolling part. The process has the advantages of simplicity, applicability to various materials, high overprinting precision and low cost.

Description

technical field [0001] The invention belongs to the field of printing technology, and in particular relates to a technology for transfer printing aluminum plating and laser on various types of plastic film printing materials. Background technique [0002] At present, the packaging bags with aluminum plating or laser marks on the market are generally composite bags, which are only suitable for materials with small tension extension. For film materials such as LDPE with large tension extension, the current printing process cannot be realized. Because, when using the current process to print products with aluminum plating or laser patterns, it is necessary to complete the printing of aluminum plating or laser patterns before overprinting other patterns. Due to the overprinting of other patterns on materials with large tension extension, due to the effect of film extension, the relative position of the material on the plate roller has changed compared with the relative position...

Problems solved by technology

Too complicated will also bring difficulties to the accuracy of subsequent overprinting

[0003] Moreover, the current printing process of transferring aluminum plating or laser marking needs to print the aluminum plating or laser marking first, and then print other patterns, resulting in cumbersome steps and high cost
