Reasons and Elimination of Printer Operators' Complaints
When you walk in the press room, you may often hear complaints from press operators. Although the reasons for their complaints may sound strange, they can be summarized as follows:
1, no color bar
2, color control error
3, color control and print content overlap
4, no side marks
5, overlap marks and printed content overlap
6, side marks are not printed on the edge of the page
7, overlap marks and printed content
8, no crop marks
9, no registration mark
10, registration mark position is wrong
11, no rules and center mark
12, the job is not arranged correctly
13, the job did not perform a correct backup
14, wrong version
15, lost pages or wrong pages
16, plate scratches
All the above problems are likely to be discovered during the preparation of the printing press. At that time, the printing plate has been installed, the ink has been adjusted, the blanket has been cleaned, the job is also registered, and the printing color is basically the same as the proofs. It was agreed that if we find out the problem, all printing plates must be re-produced, causing huge time and property losses to the printing companies.
Some printing companies want to eliminate the above problems through plate detection, but I think this is not the best solution, mainly because:
First, even if we find a mistake in the printing plate, that is after the plate is completed, so it will also bring some loss to the printing company.
Second, because the printing plate is coated with colors, it is difficult to see the details of the image.
Third, you cannot check color or overlapping images.
Fourth, it is very likely that the printing plate will be scratched when additional processing is performed.
How can we solve these problems? First, we can install a large-screen, high-resolution monitor in the prepress department, and then let the operator check the printed documents before making the plates. In this process, we can find a lot of problems and correct them in a timely manner, thus improving the efficiency of printing production while saving costs.
