A digital cold stamping process for tipping paper and tipping paper prepared therefrom

Abstract

The invention provides a digital printing method for producing tipping paper and the tipping paper prepared through the digital printing method and belongs to the technical field of printing. By the adoption of the digital printing method for producing the tipping paper and the tipping paper prepared through the digital printing method, the blank of tipping paper production through digital printing is mainly filled, and the problem that a universal digital printing technique cannot be directly applied to production of the tipping paper at all is solved. The digital printing method comprises the following steps that the preparation before printing is made, the sample of the tipping paper is designed, raw paper of the tipping paper is pretreated, printing is conducted, the designed sample of the tipping paper is input into digital printing equipment, printing is conducted on the raw paper of the tipping paper, treatment after printing is conducted, stamping treatment of half-finished tipper paper is conducted, and slitting treatment is conducted. By applying the digital printing method to the production of the tipping paper, printing ink is saved, the platemaking cost is reduced, the image-text fineness of the tipping paper is improved, and the color stability is improved; and development of the novel design of the tipping paper and novel products is promoted.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a digital cold stamping tipping paper product and a corresponding preparation method thereof. Background technique [0002] Tipping paper, also known as tipping paper, is coated and printed on the tipping base paper, followed by post-processing such as bronzing and punching according to the design requirements, and finally cut into small discs for cigarette packaging equipment to roll cigarettes. A special printing material for cigarettes, the core process of which is printing and hot stamping. Among them, bronzing is a post-press processing process that transfers anodized aluminum to the substrate by applying pressure and temperature using a predetermined plate to form a fixed text pattern. [0003] The current bronzing technology is mainly divided into the following categories: hot stamping, cold stamping and digital stamping process. [0004] Hot stamping needs to be carrie...

AI Technical Summary

Problems solved by technology

[0004] Hot stamping needs to be carried out under high temperature conditions, which consumes a lot of energy, and under high temperature conditions, the hot stamping material is easily deformed, and the hot stamping plate is heated and expanded, resulting in inaccurate overprinting; secondly, because the tipping paper is delivered to customers in the form of reels , and the hot stamping continuous pattern is more common, so the hot stamping of tipping paper can only adopt the round hot stamping method, while the traditional round hot stamping has the difficulty of plate making, the cost is relatively expensive, the hot stamping roller is time-consuming and laborious to adjust the hot stamping position locally, and debugging And a series of shortcomings such as slow flattening and large loss in the start-up stage of the equipment, and lack of advantages in the production of small batch products

[0005] Cold foil stamping can solve the above problems, but there are still some technical disadvantages: when the adhesive is coated on the surface of the printed matter, the printing plate must be prepared by offset printing, which is expensive, and different printing plates must be used for different printing materials, further increasing the cost ;Secondly, the adhesive needs to be cured, but the curing equipment will generate ozone emissions, and the ultraviolet rays will cause great harm to the human body, the operation risk is high, and the pressing and winding / unwinding operations are complicated; in addition, the traditional cold stamping devices only Fixed plate printing can be used, so it is only suitable for hot stamping treatment of the same content in large quantities, and cannot be used for hot stamping treatment of variable information printing

This technology has disadvantages: the hot stamping film used must be a special anodized aluminum material with no hot-melt adhesive on the back; the cost of toner as an adhesive between the hot stamping film and paper is high and it is not environmentally friendly; most importantly, due to the need for toner cartridges Direct contact with the substrate, causing the substrate to be limited to thinner uncoated and printed paper, otherwise the substance on the layer or printed layer will affect the image development, so it cannot affect the treated tipping paper Foil stamping
