(B) Newspaper Printing Proofing Concept

Newspaper proofing is different from traditional proof printing. This is mainly manifested in the following aspects.

(1) Newspaper printing proofing is not contract proofing. Newspaper printing customers and newspapers generally do not print according to proofs, and the color quality of newspaper printing cannot fully meet the quality of proofs.

(2) Newspaper printing proofs are proofs of color correction. Their main purpose is color correction, in which the printing color is controlled within an acceptable range, especially for colors with small individual tolerances (such as purple, blue, etc.) Cabinet control, to control the machine ink a basis. Therefore, it is generally believed that newspaper printing can only perform color control of the density method without the necessity of chroma control.

(3) Newspaper printing proofs are the basis for dispute resolution. With more standard color proofs, you can effectively distinguish between different aspects of responsibility. Therefore, the printing department of the client newspaper is more interested in using digital proofing.

(4) As different newsprints are used to print different newspapers, and the adjustment of the printing speed, the range of color fluctuations of the newspapers is large, and the reference of the proofs is not strong.

From the actual production characteristics of newspaper printing, the printing process problems that should be solved in proofing are mainly manifested in the following aspects.

(1) Control the color. Provide a reference sample, as the basis for the adjustment of printing ink, can improve the consistency of the printing color of different operators, different machines, and can also prevent the mistaken version.

(2) Controlling the edition order. If the sample sheet is pre-arranged in advance in the order of the edition, it can serve the purpose of pre-order control. However, after proof-printing, the effect of the version control is not obvious.

(3) Check the accuracy of the plate making. Through proofs, you can check whether there are plate-making problems.

(4) Check the printing problem. Through the comparison of prints and proofs, it can be checked whether there are printing problems, such as rubber crushing.

Above these functions, the screen soft proofing can be done, and this proof sheet is on the computer screen.
