Method for first ironing and then printing of cigarette packet

Abstract

The invention discloses a method for first ironing and then printing of a cigarette packet. The method comprises the following steps that A, a gilding press is used for pressing blank printing paper and a gilding film under the condition that gilding pressure is 0.7-1.8 T and the temperature is 90-150 DEG C, and an electrochemical aluminum layer on the gilding film is transferred to the hollow printing paper to form the gilding paper; B, an offset machine is used for conducting offset printing on the gilding paper under the printing pressure of 0.26 T, and a finished product is obtained after embossing and die cutting. The method for first ironing and then printing of the cigarette packet is an improvement on traditional technique methods and technological conditions, the product printed through the method is good in forming performance, bright in color, free of the phenomena of net point falling or aluminium powder falling or fracturing. The overprinting precision of the cigarette packet prepared by the method can be smaller than 0.15 mm, high-precision overprinting is achieved, and the printing requirement of high-graded cigarette packages is met.

Description

technical field [0001] The invention relates to the technical field of printing and decoration technology, in particular to a method for printing cigarette packs after they are hot. Background technique [0002] With the overall improvement of the country's anti-counterfeiting printing and packaging technology, consumers have higher and higher requirements for the exquisiteness and craftsmanship of product packaging. In the past, the appearance and aesthetics of a single printed product have been difficult to meet the requirements of consumers. The hot stamping and printing process has been widely used in the anti-counterfeiting packaging market. At present, the hot stamping film of cigarette packs printed by the hot stamping and printing process has poor adhesion and is prone to film pulling, resulting in a low yield rate of products. The bit accuracy is not high, and it cannot meet the printing requirements of high-end cigarette pack products. In addition, the current cig...
