Importance of quality control of raw materials in the printing process

The quality control of raw materials in the printing process The selection of raw materials in the printing process will have both artistic effects and technical performance on the printed image, and it will also affect the stability of the printed image quality. In addition, the performance of raw materials can also affect production efficiency. Raw materials that do not meet quality requirements can reduce productivity and waste operator extra energy.

The most important raw materials in the printing process are paper or other printing materials and inks. Of course, less important materials such as adhesives, stamping foils, varnish, and binding materials are also included.

The purpose of using other materials in the printing process is to form an auxiliary material for the final image on the substrate, such as a developer solution, a proofing material, a ps plate, and other materials used as an image carrier; materials used in the printer to assist in forming an image, such as The components in the offset fountain solution; there are also some consumable materials, such as tapes, polyester bases, lubricants, and some developer-fixing drugs; these can be classified as consumables and are not discussed here.

Many properties of raw materials can be quantified by appropriate tests. However, these tests sometimes require sophisticated equipment and skilled operators. The testing of raw materials takes a lot of time to test and perform data analysis and interpretation of the results. In addition, the results of the tests do not necessarily serve as a predictor of the quality of printed products. Therefore, how to selectively detect raw materials becomes an important issue. The key issues for the management personnel of printing companies must grasp the quality control of raw materials are: what important printing performance should be monitored for raw materials; what monitoring items should be selected as a means of predicting the printing performance of raw materials; how much should be invested in testing in order to achieve the maximum benefit of printing enterprises? .
