Paper package box quick proofing method

Abstract

The invention discloses a paper package box quick proofing method, which relates to the technical field of printing, in particular to the field of proofing treatment of paper package boxes before printing. The method overcomes the drawbacks of high proofing cost, long proofing production period, large paper consumption, low production efficiency, low machine utilization rate and very high electric energy consumption of the conventional paper package box printing proofing method. The method comprises the following steps: 1) scanning the package boxes by using a scanning device, and saving the scanned proof plane pictures generated after scanning into a computer; 2) amplifying the scanned proof plane pictures and original pictures twice by different amplification factors, comparing the screen dots of the scanned proof plane pictures with the screen dots of the original pictures after each time of amplification, regulating the screen dot data of the original pictures to make the screen dot data of the original pictures consistent with those of the scanned proof plane pictures; 3) storing the regulated original pictures, and making films or computer to plate (CTP); and 4) proofing on a printer. When the method is used, proofing can be successfully realized at a time, the working efficiency can be improved effectively, the labor intensity can be reduced, pollution and waste water production can be avoided, the working environment can be improved effectively, and the environment-protection requirement can be met. In addition, the normal use efficiency of the device can be increased, the paper and power consumption can be reduced considerably, the utilization rates of operators and operation sites can be reduced greatly, and the cost can be reduced effectively.

Description

technical field

[0001] The invention relates to the technical field of printing, in particular to a proofing processing method before printing of a paper packaging box. Background technique

[0002] At present, for customers to provide original file pictures and packaging box samples, the printed packaging boxes must be consistent with the color of the sample packaging boxes. The existing printing and proofing methods for paper packaging boxes are as follows: electrical separation of the packaging boxes, through visual inspection, Based on personal experience, I feel that I adjust the original picture on the computer, and then print the film (PS version) or CTP (direct-to-plate), make a proof on the printing machine, and compare the proofing result with the packaging box sample provided by the customer through visual inspection. Then modify it, and then make a sample again. Repeat this many times. When the printing and proofing result is consistent with the color of the pack...

[0011] The present invention comprises the following steps:

[0012] 1) Use the scanning device to scan the sample of the packaging box, and store the scanned image of the sample generated after scanning into the computer; the scanning device is an existing scanning instrument on the market, which includes a picture generation system, a data line , Repair the software system. The data line connects the instrument and the computer in series, and the picture of the sample packaging box is transmitted to the computer through the data line and stored.

[0013] 2) Through the existing image magnification software, the sample scanned image and the original file image are enlarged twice or more, for example: 25 times, 50 times and 100 times, and at the same time, each enlarged Compare the dots of the sample scanned picture with the dots of the original picture, and adjust the dot data of the original picture to make it consistent with the dot data of the sample scanned picture; the ...
