Print quality management measures

Editor's note: Product quality is produced, not tested. To control the quality of products in the production process, we must first start from the source, focus on prevention, and attach great importance to ideology. In addition to the industry standards (CY) and national standards (GB), the quality standards of printed products include contracts signed by users. With regard to printing standards, other users of the society other than news publishing units do not fully understand it.
At present, a considerable part of the printing market is printed and printed by non-press and publishing companies. Their commissioned work processes are complex, require short construction periods, and are low in price. As a result, printing houses use inexpensive paper and raw and auxiliary materials to process printing products. Quality has caused hidden troubles; on the other hand, the quality of first-line operators in printing workshops is uneven, there are more temporary workers, the operation time is short, and there is little experience; in addition, the ability of business personnel is poor, little knowledge of the printing business is known, management is not in place, etc. For reasons, these have caused wrangling between the deputy printing unit and the printing plant.
1. Management measures taken before and after the printing of books and periodicals Checks and verifies the printed orders and construction orders. Whether the name of the book, serial number, bar code, advertisement number, copyright content, and pricing are all the same or not.
Check whether the front cover, insert sheet, inner text film and proofs are complete, the page number sequence is clear and correct, the place where changes are required should be marked clearly, and the signatures, originals, sample books, and photo materials should be properly kept.
Check whether the number of printed sheets, the open size, the cover, inserts, and the inner paper should be clear and correct, whether there are inserts, the order of the inserts, whether the front cover is post-processed, whether there is any stitching, and the binding method must be accurate.
Check the number of impressions, the number of distributions issued, the distribution and distribution address, the package method, contact person and telephone number, and request the date of publication.
2. The quality management of the offset printing shop will review the contents of the construction worksheet in detail, be familiar with the sample or the sample, check the number of prints, check the printed sheets, check the quality of the printing plate, the open size, and the quality of binding.
After the first print sample comes out, first fold the page number, check the order is correct or not, is the back of the ink is the same, there is no missing picture or drop the word, rules line, mark, check mark is complete. A multi-unit co-printing a book, to determine the color of a unit, the rules as a benchmark.
The color covers or texts should be checked against the proofs, and the fixed titles and page numbers must have the same period of time. The book is the same. Check whether the colors of the diagonal folds are consistent, whether the colors of the joined pages are the same, and whether the colors of the pages between the printed sheets and the printed sheets are the same.
In the printing, the “three-diligence” operation method was adopted: Diligently contrasted and signed, diligently stirred ink fountains, and diligently looked at the surface moisture. The implementation of the system of four non-indian prints: The construction list is not clear, not printed, no signature is not printed, there is no doubt that the printing is not clear, and there is a problem with the quality.
These quality management measures are distributed to each salesperson and machine operator, and they are carefully checked and checked one by one in the business negotiation handover and production operations. After a period of implementation, the production process has been streamlined and the quality of the product has been significantly improved. It has also been possible to check the mistakes made by the company, recover the losses in a timely manner, win the reputation of the customers, and create a good environment for printing companies' external business.
At present, with the continuous updating of production facilities in various printing plants, customers are more demanding on the quality of printed matter and the production cycle, which imposes higher requirements on the quality of skilled workers. In the current situation where all units of technical workers are relatively scarce, it is imperative to formulate simple and easy-to-use management measures that allow the first-line operators to perform checks and control, which can indeed play an important role in ensuring product quality.
