Printing proofing the most commonly used way points of digital proofing and the traditional proofing is introduced.a proofing, and two each have each advantages and disadvantages, the biggest characteristic of the digital printing is of low cost, fast speed, but will not equal to the printing sample, so this way, the sample can only be used as a reference sample, usually as a check before printing proofing prints; Computer proofing is the biggest characteristic of small difference with the last batch of printing products, information is accurate, especially for the high quality of printed matter to proofing, but the cost is high, is charged by printing costs.

We will introduce the following details:

The sample is the weight basis of the quality control of printed matter and the tool to communicate with the customer, which is mainly reflected in the following two aspects.

First, the sample can help users check the information contained in the document so that they can be modified in time, such as fonts, images, colors, and page Settings. Color is the most difficult to control in the proofing, because different printing materials, ink and dot increase rate will cause the change of sample color.

Second, the sample can be used as a contract between the customer and the printer. The contract sample should provide the color consistent with the final print, and the contract sample should be typed not long before the printing, so as to avoid the loss of color and distortion due to the longer placement time. At present some printing enterprises, for the business, in order to please customers, use the digital proofing to print the sample color brilliant. After the client is very satisfied with the signature, the actual printing is difficult to meet the fine requirements. In the end, the customers often have the phenomenon of return, claim, price and so on because they do not conform to the sample of proofing. The printing company will end up busy for a while and may even lose some capital.
