Offset printing is a common printing method that can produce high-quality prints. However, in order to produce high-quality prints, strict quality control is required. Let's explore the quality control of offset printing and our experience and practices in this regard.

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

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

Production and protection of printing plates. Printing plates are important tools for transferring printed patterns and must be carefully crafted and protected. When making, attention should be paid to the specification of the plate, the size of the plate, etc. In terms of protection, it is necessary to prevent deformation and wear of the printing plate.

Selection and management of printing materials. Printing materials are one of the important factors that determine the quality of printing. The choice of printing paper should be selected according to the requirements of the printed matter. The choice of ink should be selected according to the requirements of the color and gloss of the printed matter. In addition, it is also necessary to manage the printing materials to ensure the stability of the printing quality.

Control of the printing process. During the printing process, it is necessary to control parameters such as printing pressure and printing speed 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 problems in a timely manner.

We have a wealth of experience and practices in the quality control of offset printing. In the commissioning and maintenance of the printing press, we pay attention to the maintenance of the machine, regularly cleaning, lubricating, overhauling the printing press, etc., to ensure the normal operation of the machine. In the production and protection of the printing plate, we use high-precision plate making technology to ensure the specification and dimensional accuracy of the printing plate. In the selection and management of printing materials, we have a complete supply chain management system for fine management of printing materials. In the control of the printing process,
