Printing accidents are the most reluctant, but also the most frequently encountered problems of printing plants and customers. One of the reasons for the emergence of printing accidents may be that the quality of the printed matter produced by the printing plant is unqualified, and another reason is the existence of printing errors. For professionals engaged in printing for a long time, some printing errors are objective and impossible to prevent; For customers, the differences in these products are unacceptable.
When the printing company and the customer hand over the process of custom Tissue paper printing, there will often be printing plants say that our products are qualified, but the customer insists that the product is unqualified, and can not bear it. As a result, there are disputes, the communication between the two sides is very difficult, customers think that the printing plant's products are not qualified, looking for excuses, unreasonable sophistry; The printing house thought that the customer was unreasonable and did not want to pay.
Here, we remind you that some objective errors exist in custom Tissue paper printing to make clear to customers first, so that customers can understand how much error there is, and prevent returns and disputes later. Some objective errors are due to the limits of the machine itself, and these errors are unavoidable, not human factors; Such as poor management, improper quality control and other factors appear, which is the reason for the printing factory, you can ask for rework, the error includes the following points.
1. Text errors in typesetting:
Typesetting manufacturing is an important process before printing. Typesetting is a text arrangement work carried out by designers with corresponding software under the instruction and request of customers. Therefore, from the point of view of the printing house, before plate printing, customers are generally asked to stop signing confirmation. However, sometimes due to the time crunch of the live parts, and based on the level of trust between the two parties, the customer may sometimes delegate the rights and interests of typesetting confirmation to the printing house in full. In this case, the client may blame the designer if something goes wrong, such as a typo or other typographical error. It should be said that this wrong presentation is not caused by the mechanical problems we said above, but the whole process control problem.
Two, the film and proofing error:
After the designer completes the typesetting work, it enters the scheduling process, which is what we usually call the film proofing. Generally speaking, the accuracy of the laser phototypesetter is in the range of 0.01C 0.1mm. At the same time, due to the difference in the film used, it will also cause a certain error.
Third, color error:
There are three kinds of color error, the first is the color deviation between printed matter and proofing; The second is that there is a certain level of color difference before and after the same batch of prints; The third is that there is a bias between the color of the product printed in the print and the actual color itself. The first difference is that we usually say that the printing can not catch up with the proofing, the reasons have been described above, such as ink problems, paper problems, dot recovery problems. Regarding this difference, the printer should try to follow up the sample, if the difference is very large, it should inform the customer in time, and the customer will sign the sample in person.
Four, paper error:
Due to the problem of papermaking process, the brightness, thickness and texture of the same paper consumed by different papermaking manufacturers will be different.
Five, printing machinery error:
The error of printing machinery is manifested in two points. One is the overprint accuracy problem, the other is the ink color problem. We know that the practice of color printing is four-color overprinting, that is, red, yellow, blue, black and four colors are superimposed together, and the content of the overprinting is reflected on the film, which is the dot we mentioned earlier, which is a small dot. According to China's printing machinery industry specifications, the registration accuracy of the printing press, that is, the superposition accuracy of the network is 0.033mm, and the practical mechanical accuracy is generally higher than this specification, mostly 0.01mm, and of course, some printing machinery is 0.1mm.
Six, cutting size error:
After the printing is completed, the next important step to enter is to use a paper cutter to cut printing waste. When cutting waste products, due to the error problem of the cutting tool itself, the error after cutting waste products is also objective.
custom Tissue paper printing seems simple, in fact, it is a test of the printing ability of the printing company, only the choice of advanced equipment and rich experience of the enterprise, in order to obtain the most ideal printing effect in the shortest time and the smallest cost.
