Embodiment Construction

[0013] The screen printing-based plateless bronzing process provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014]

[0015] figure 1 It is a flow chart of the plateless bronzing process based on screen printing in the present invention.

[0016] Such as figure 1 As shown, the plateless bronzing process based on screen printing includes the following steps:

[0017] Step S-1, preparing a bronzing graphic negative. Bronzing pictures and texts can be large-area patterns and texts above size 5. The pattern is composed of solid bottom or lines, and the text font is not limited. The positive image negative is selected as the graphic negative, and the quality of the graphic negative must meet the quality requirements for screen printing.

[0018] Step S-2, making a screen printing plate. Choose a polyester net with a mesh number of 300 lines. The direct photosensitive plate-making method is used for the dryi...

Abstract

The invention provides a silk-screen printing based plate-free hot-stamping process. The plate-free hot-stamping process is characterized by including: for preparation of hot stamping image-text films, selecting the positive image-text films as the image films; for drying of silk-screen printing plates, manufacturing the plate in sensitization by adopting a direct method; for blending of hot-stamping bottom oil and additives, respectively blending the hot-stamping bottom oil, curing agent and diluent in the mass ratio of 10: (1.5-2.5): (1.0-1.5); for silk-screening printing plate, printing mixture obtained from blending of the hot-stamping bottom oil and the additives on the silk-screen printing plate to obtain a hot-stamping image-text bottom layer; for drying and curing, placing the hot-stamping image-text bottom layer under indoor temperature for 30mins prior to sending the same to a drying box for drying at the temperature ranging from 60DEG C to 70DEG C for 8-13mins, and naturally cooling the hot-stamping image-text bottom layer under the indoor temperature for 1 hour after drying. The surface temperature of a hot-stamping drum is heated to 90-110DEG C, pressure of a stamping machine is regulated to the largest, and stamping speed is regulated to be slow.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a plateless hot stamping process that matches printing materials, screen printing technology and hot stamping technology. Background technique [0002] There are two types of hot stamping processes for non-absorbent materials: direct hot stamping and indirect hot stamping. Indirect hot stamping, also known as screen printing hot stamping, is a printing process that stops solid phase transfer by hot stamping. Blending→screen printing→drying, curing→hot stamping. Although indirect hot stamping adopts the method of printing first and then hot stamping, which has greater flexibility in the stamping pattern and stamping area, and the cost is lower, but after using this process to stamp on the surface of non-absorbent materials, the gold foil layer is prone to cracks and wrinkles And problems like orange peel. Contents of the invention [0003] The present invention aims at the ...
