Offset printing is a common printing method, which can produce high-quality prints. However, in order to produce high quality prints, strict quality control is required. Let's discuss the quality control of offset printing and our experience and practice in this area.

The quality control of offset printing mainly includes the following aspects:

Press commissioning and maintenance. The printing press is the core equipment of offset printing production, and its normal operation must be guaranteed. The debugging of the printing press includes the adjustment of the color and the positioning of the color plate. Maintenance includes regular cleaning, lubrication, maintenance, etc., to ensure the normal operation of the machine.

Production and protection of printing plates. The printing plate is an important tool for transferring printing patterns and must be carefully made and protected. When making, you need to pay attention to the specification of the layout, the size of the layout, etc. In terms of protection, it is necessary to prevent the deformation and wear of the printing plate.

Selection and management of printed materials. Printing material is one of the important factors that determine the quality of printing. The choice of printing paper should be based on the requirements of the print to choose the right paper. The choice of ink should be based on the color of the print, gloss and other requirements to choose. In addition, printing materials need to be managed to ensure the stability of printing quality.

Control of the printing process. In the printing process, it is necessary to control the printing pressure, printing speed and other parameters to ensure the consistency and stability of the printed matter. At the same time, it is also necessary to inspect the printed matter and deal with the problems found in time.

We have rich experience and practice in offset printing quality control. In the debugging and maintenance of the printing machine, we pay attention to the maintenance of the machine, and regularly clean, lubricate, and overhaul the printing machine to ensure the normal operation of the machine. In the production and protection of printing plates, we adopt high-precision plate-making technology to ensure the specification and dimensional accuracy of printing plates. In the selection and management of printing materials, we have a complete supply chain management system for fine management of printing materials.
