The basic tasks and three purposes of Chocolate Drawer Box With Transparent Window prepress proofing

The basic task of proofing

The basic task of proofing is to produce qualified products and provide satisfactory samples of printing products for proofreading and platemaking printing personnel. At the same time, in some special cases, it can also replace printing by proofing or directly complete the production task of a small number of products. Reduce the waste caused by large equipment.

The main purpose of proofing

One is to test the quality of the plate, to provide parameters for the plate making process. Check the format specification, text content and overprint performance of the printing plate by proof. Check whether the color, level, gray balance and uniformity of the proofs meet the quality requirements; Provide the field density value, gray balance value, dot increase value and the maximum or minimum reproduction value of dot for the plate making process calibration and process design.

The second is analog printing, providing proofreading proofs for customers and editors. And proofread the proofs and predict the quality effect of printed matter, confirm the quality standard of formal printing, and accept the sample for printing.

The third is to produce, to provide standard proofs for the printing process. The printing process is based on the proof of material preparation and machine adjustment, the proof as the standard printing and testing product quality
