Example Embodiment

[0016] The present invention will be described in detail below in conjunction with embodiments. To print a product with aluminized or laser pattern, the specific steps are as follows:

[0017] a. Pre-press design, add a pattern that you want to express with aluminum plating or laser in the layout pattern according to your needs. Design the pattern printing plate that requires aluminum plating or laser in the last color, because printing and lamination are carried out simultaneously, too long a travel of the material will dry the glue excessively and affect the transfer effect.

[0018] b. Plate making, engraving the pattern on the plate roller, according to the printed surface and inner printing, the pattern is divided into two engraving methods on the plate roller. The screen line of the plate roll for printing aluminized film or laser film is slightly deeper than that of normal ink printing, which is beneficial to the transfer of aluminized or laser film. The color sorting is ar...

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...
