Printing method and product thereof

Abstract

The invention discloses a printing method. The printing method comprises the following steps: spraying printing ink on the surface of an object to form a printing ink layer; curing printing ink in theprinting ink layer; and after printing ink is cured, forming a hot-stamping material layer on the printing ink layer by hot-stamping. Besides, the invention further discloses a product obtained by using the printing method.

Description

technical field [0001] The present application relates to printing technology, and in particular to a printing method capable of making a metal sheet have a three-dimensional effect and products manufactured by the printing method. Background technique [0002] Metal flakes (metal labels) with a three-dimensional effect and metallic luster are widely used in the fields of films and electronic products, and are especially used for making logos, trademarks, names, etc. on various cards and cardboard. Foils are usually pre-coated on both sides and held between a clear film and a release liner. When the metal foil needs to be attached, the release paper needs to be manually peeled off, the metal foil is aligned to the predetermined sticking position, and then the transparent film is pressed to stick the metal foil, and finally the transparent film is peeled off. The traditional process of attaching metal sheets can be realized manually or automatically by equipment. However, m...

AI Technical Summary

Problems solved by technology

However, manual operation has problems such as low efficiency, poor positioning accuracy, large fluctuations in pasting quality, and high waste rate of manual peeling.

Even if the operation of automatic metal sheeting is carried out through equipment, the following problems still exist: the cost of metal materials is high; the consistency of incoming materials is difficult to control, resulting in an increase in failure rate; when the release paper is peeled off, the metal sheet is likely to fall off, resulting in an increase in the scrap rate

However, silk screen printing needs pre-made plates, and a set of silk screen printing plates needs to be made for each different pattern, so the cost is high and the process is cumbersome

In addition, the thickness of the printing ink in the silk screen printing process is only about 10 microns each time. To precisely realize the printing of a certain thickness of ink, it often requires many times of silk screen printing, so the efficiency of silk screen printing is very low.

In addition, the edges of the screen printing ink layer are neat. After the hot stamping material layer is further added to the ink layer, the height difference between the top surface of the hot stamping material layer and the surface of the object will further increase. When the surface of the hot stamping object is covered with a protective film , it is easy to leave air gaps or air bubbles at the angle between the edge of the hot stamping material layer and the ink layer and the surface of the object, which not only affects the appearance, but also easily leads to the separation of the protective film from the surface of the object
