The offset printing production process mainly includes the following steps:

Prepress preparation: This is the basic work of printing, including manuscript analysis, graphic design and preparation of plate-making materials. Manuscript analysis ensures that the clarity, color accuracy, and resolution of the manuscript meet the printing requirements; Graphic design is carried out according to customer needs, including the combination and layout of text, images and colors; The preparation of plate-making materials is to convert the designed graphic information into a printing plate that can be recognized by the printing machine.

Plate making: Producing a printed plate is a critical step, including processes such as film exposure and development. The film is output to the PC film through the device, carrying all the design information in preparation for subsequent plate making.

Printing operation: This is the core link of offset printing, including trial printing and formal printing. The purpose of trial printing is to check the printing effect and adjust the parameters of the printing machine, such as pressure and ink balance, to ensure the printing quality; Formal printing is carried out after the trial printing is correct, and the ink viscosity, printing pressure and overprint accuracy and other elements need to be strictly controlled in the process to ensure that the color of the printed matter is accurate and the graphics and text are clear.

Post-press treatment: After printing, lamination, embossing, folding, binding and other treatments are carried out to improve the quality and visual effect of the printed matter. This step includes drying, cutting, binding, etc., to ensure that the print is not damaged during transportation and is delivered according to the customer's requirements.

Characteristics and application areas of offset printing
Offset printing is an efficient and high-quality printing method, which is widely used in packaging, labels, advertising, printed matter and other fields. Its features include the use of lithographic printing, the transfer of ink to paper or other media through blankets, suitable for books, newspapers, albums, posters, etc.

Common problems and solutions
In the offset printing process, common problems include ink spots, inaccurate overprinting, etc. Solving these problems requires ensuring the perfect presentation of prints by checking the quality of prints in real time and making the necessary adjustments and maintenances.
