Ensure high quality printed products! Please insist on the following five points!
The first point;
      For printing companies, printing quality management should include the whole process of printing production such as prepress design, printing preparation, printing production, and finished product inspection, so as to fundamentally protect the printing quality of printed products.
     The original documents are stored in the corresponding product folder according to the product name. After confirming that there are no other related files, check the received original documents. The inspection items include: whether the image resolution reaches 300dpi, whether the font is missing, whether the printing adopts the CMYK color mode uniformly (if other color modes are used, it should be modified immediately), the picture Whether it is missing, whether the layout has abnormal effects or does not meet the standard, and whether the text content is incorrect or not. If you have any of the above problems, you should promptly give feedback to the customer and communicate well with the customer.
     After confirming that the original document is ok, generate an electronic file (AI format, CDR format) to be output, and then the computer producer performs a self-test on the electronic file according to the requirements of the production instruction sheet, and focuses on checking whether the path of the joint layout is correct, and the file (link Version) Is the size, content, and direction (the version) correct? After the self-test is completed, a VPS file is generated to facilitate screen proofreading. The full-time inspector conducts a self-test according to the requirements of the production instruction sheet, and focuses on checking whether the contents (color) and other related printing requirements of the document (joined version) are incorrect. After the confirmation is correct, the electronic document will be confirmed by the business personnel or the customer after digital proofing as required. After confirmation, the official production will be required according to the instruction sheet.

Second point;
 1. Inspection of raw and auxiliary materials
      It is necessary to use appropriate testing equipment, tools and means during the inspection process. For example, the pre-coating corona treatment requires the use of a 38# Dyne pen to draw a line on the surface of the pre-coated film with appropriate force. If the line does not shrink or condense after 5 seconds, the pre-coated film is electrically charged. Halo treatment. For example, when checking the ink adhesion of the surface of the PP film, a simple nail scraping method can be used, and the nail is scraped back and forth 4 or 5 times at the printing portion, and the ink is not detached, and the quality is qualified, which is simple and effective. .
2. The first three-level signing
Before the official printing and production, you need to sign the first sample, and you should implement a three-level signing, including the leader, quality inspector, and squad leader. During the printing production process, the operator requested the sampling according to the requirements of the three diligences (stirring ink, diligent sampling, diligent wiping blanket), comparing with the first sample, and finding problems in time. The quality inspectors randomly check the problems, record the problems found, and notify the operators to adjust them in time, and deduct the points according to the provisions in the quality score, perform statistics on a monthly basis, deduct the corresponding bonus according to the points, and urge the operator. Strengthen quality awareness.
3. Control of temperature and humidity in the workshop
  The change of temperature and humidity in the workshop will directly affect the performance of the raw and auxiliary materials, such as low temperature in winter, easy deformation and deformation of the paper, and poor fluidity of the ink and adhesive, which indirectly affect the printing quality. Therefore, the printing workshop requires constant temperature and humidity, the general temperature is controlled at (21 ± 2) °C, and the humidity is controlled at 45% to 60%. It is recommended to use air conditioners, hot air blowers and exhaust devices to adjust the temperature and humidity of the workshop.
4. Management of laminating products
    Laminating products pay special attention to foreign objects on the surface of printed products, especially pharmaceutical film products. In order to avoid the generation of foreign matter in the film, according to the requirements of clean production and fixed management, the production workshop is not allowed to open windows, and the drainage vents connected to the outside world and the bathroom in the factory area are provided with window screens, plastic curtains, floor drain nets, mosquito killing lamps, and anti-mosquito lamps. Rats and fly-proof mosquitoes, etc., and often check for repairs. Supervised by the supervisor of the workshop, the problem was reported to the maintenance department in time.
