1. For the film, pay attention to the fact that there should be no holes (light leakage) in the field. The corner lines of each film of CMYK must be completely matched, no flowers, no scratches.
2, proofing must be carefully proofread, responsibility is dripping!
3, when signing, pay attention to the required paper, printing quality, delivery time, and post-process requirements, not sloppy!
4, with the single.
The first point: pay attention to the color of the printing (not true, enough, heavy or light, mainly against the proofing, I often say this when I am with the single, red is heavy, young, the ink is a bit thick…………);
The second point: Every part of the print, the workers will take a few shots to see the sample, you also follow, the printing machine running for a period of time may appear a certain color running light or heavy.
The third point: the version (that is, the CMYK corner line is not aligned, it is best to use a magnifying glass, can see the error of 1, 2 lines);
Fourth point: pay attention to whether there are any extra white spots or other color points in the dark part of the printed matter, and erase it at any time;
The fifth point: pay attention to the light color of the printed matter, there are no obvious dirty spots, always point out, let the printing workers wipe the plate.
