Why do Gift Paper Boxes need to be proofed before printing?
The work of loading the finished printing plate on a proofing machine for trial printing is called proofing.
Proofing should correctly reproduce the original tone level and color.
Gift Paper Boxes, why do you want to make a sample before printing?
Proofing is an important process. The function of proofing is:
①Check the quality of each process of plate making. Use proofing to check the effect of color separation, etc., and feed back to the previous process for modification.
②Provide proof of proof for customers. After the proofreading is signed by the customer, it can be printed.
③Provide basis and reference data for ink color, specifications, etc. for formal printing.
The most commonly used method of printing proofing is divided into digital proofing and traditional proofing, that is, on-machine proofing. The two have their own advantages and disadvantages. The biggest feature of digital printing is low cost and fast speed, but it must not be equivalent to printed samples, so this method The sample draft can only be used as a reference sample, usually as a pre-print proofing for proofreading the printed draft; the biggest feature of the machine proofing is that it is small in difference from the final batch printed product and the information is accurate, especially for high-quality prints that need to be proofed on the machine. But the cost is high, and it is completely charged according to the printing fee.
We will introduce in detail below:
The proof is the weight basis for printing quality control and a tool for communication with customers. Its functions are mainly reflected in the following two aspects.
First, the proofs can help users check various 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 proofing, because different printing materials, inks and dot increase rate will cause the color of the proof to change.
Second, the proof can be used as a contract between the customer and the printing house. The combined sheet should accurately provide the same color as the final printed product, and the combined sheet should preferably be printed shortly before printing to avoid discoloration and distortion of the sample sheet due to a long storage time. At present, some printing companies use digital proofing to print the proofs in dazzling colors for their business and to please their customers. After the customer has signed the sample with great satisfaction, it is difficult to meet the requirements of exquisite sample in actual printing. In the end, customers often return goods, claim for compensation, and bargain prices due to non-compliance with the proofs. Printing companies end up in vain and may have to pay for some capital.
