How to improve the quality of printed products

The quality of the product is produced, not tested. Similarly, in order to improve the quality of printed products, we must start from the source, pay meticulous attention to ideology, strictly control production, and be preventive, and take preventive measures. To grasp the following aspects of the work:

First, do a good job in the management of the transfer of book printing before and after printing.

(1) It is necessary to check whether the name, serial number, bar code, advertisement number, copyright content, and pricing of the appointing committee's printing orders and construction orders and books and periodicals are all consistent and have no changes.
(2) Check whether the front cover, insert sheet, inner text film and proofs are complete, and 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.
(3) Check the number of printed sheets, the open size, the cover, inserts, and the inner paper are clear and correct, whether there are inserts, the order position of the inserts, whether the cover is post-processed, whether there is a mouth, and the binding method should be accurate.
(4) Checking the number of impressions, the number of distributions issued, the address of distribution and distribution, the package method, contact person and telephone number, and requesting the date of publication.

Second, do a good job of quality control of offset printing workshop

(1) Examine the contents of the construction worksheet in detail, familiarize with the sample or sample, check the number of prints, check the printed sheets, check the quality of the printing plate, the open size, and the binding quality.

(2) After the first printed sample is printed out, first fold the page number, check whether the order is correct, whether the ink is in the same color, whether there is missing or missing characters, and whether the rules, labels, and check marks are complete. Multi-unit printing a book with the same, to determine the color of a unit, the rules as a benchmark.

(3) The color cover or the content should be checked against the proofs, and the fixed titles and page numbers must have the same period of time. The book is consistent. 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.

(4) In the printing, we must do “three jobs”: check the signatures, dilute the ink fountains and diligently read the water on the pages.

Implementation of the "four non-printing" system: construction orders are not clear, not printed, no signatures are not printed, there are doubts do not figure out not to print, knowing that quality problems are not printed.

These quality management measures must be clearly understood by each salesperson and machine operator. In the business negotiation transfer and production operations, one by one carefully check and check execution. 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 find the publisher's mistakes, recover losses in a timely manner, win the reputation of customers, and create a good environment for printing companies' external business.

With the continuous updating of production equipments in various printing plants, customers are increasingly demanding the quality of print products 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, some practical and feasible management measures are formulated so that the first-line operating workers can be compared and implemented. This can indeed play an important role in ensuring product quality.
