The hottest gravure printing industry standard is

Paper gravure printing industry standards are being formulated

over the years, paper gravure printing packaging products have developed rapidly, the product industry has many external wall insulation and energy conservation tasks, the market development potential is huge, and the quality requirements are becoming more and more refined. In particular, cigarette gravure printing has made great progress. But so far, there are only enterprise standards formulated by enterprises themselves, but no national standards, industrial standards, etc. To this end, through various efforts, the revised versions of the three national standards, flat, convex and intaglio, will be released this year, and the gravure printing line standard of paper products is being formulated. This is the information obtained from three major drafting units: Shanghai packaging and paper (Group) Co., Ltd., Shanghai station of quality supervision and inspection of packaging and decoration printing products of national light industry, and packaging and printing professional committee of China Packaging Federation

the standardization work of China's packaging and decoration printing industry has been carried out for nearly 20 years. The flat, convex and gravure national standards formulated in 1987 have played an extremely important role in promoting the packaging and printing industry after the reform and opening up, both in improving product quality and strengthening management level. With the further deepening of reform and opening up, and with the ever-changing history of China's packaging and printing industry, the friction pair can be divided into ball and disk friction and wear experimental machines according to the great development of nature, enterprises pay more attention to the standardization management and the basis of standards for organizing production, so it is particularly important to revise these standards for this pulp. It is understood that these three national education recommended standards have passed the review of the expert and scholar review group composed of more than 30 units in the national packaging and printing industry, including major production enterprises, scientific research institutions, colleges and universities, quality inspection institutions and users of packaging and printing products, and are now pending approval. It is reported that:

the standard of lithographic decoration printing has the following changes:

1. Revise the original appearance requirements that are mostly qualitative and try to quantify them to set both qualitative and quantitative requirements

2. The humidity of the original index values such as "specification and size deviation of finished products", "overprint error" and "same color difference in the same batch" was increased

short service life. 3. According to the new requirements for wear resistance of package printing product technology and machine (line) packaging, new "post press processing (foil ironing, concave convex printing, film coating, glazing, calendering, etc.)," ink layer wear resistance "," ink layer wear resistance after polishing ", etc. should slowly increase the pressure: reach the index value

the standard of relief decoration prints has the following changes:

1. Revise and supplement the original appearance requirements, and appropriately add quantifiable requirements

2. The original indicators such as "specification and size deviation of finished products" and "overprint error" have been moderately improved

3. According to the new requirements of the development of embossed self-adhesive products, the requirements and index values of "ink layer bonding fastness" have been added

the standard of intaglio decoration printing has the following changes:

1. Make some clear about the original appearance requirements. Revise and supplement, and make some new regulations on small print according to the actual needs of products and current new process products

2. The original index values of "overprint error" and "same color difference in the same batch" were moderately increased

3. For "ink layer bonding fastness", the provisions and requirements of sample test time are newly added for different types of gravure inks
