3. Color error:
There are three kinds of color errors. The first one is the deviation of the color of the printed matter and the proof; the second is the inconsistency of the color before and after the inside of the same batch of printed matter; the third is the deviation between the color of the printed product and the actual color of the product itself. The first difference is that we often say that we cannot keep up with the proofs during printing. The reasons for this are discussed above, such as ink problems, paper problems, and dot restoration. For this difference, the printing staff should try their best to catch up with the sample. If the difference is very large, the customer should be informed in time and the customer should sign the sample in person. The second difference is also an objective problem, and the printing machinery itself has always been difficult to solve. We know that during the printing process, printing ink is a dynamic and balanced process. When printing, when the ink on the ink roller is reduced to a certain extent, the printing machine will automatically ink to compensate. The "certain degree" here will directly lead to the deviation of the color of the finished product printed on the front of a batch of printed jobs and the finished product printed on the back side. The third difference is in fact a psychological problem. We once met a customer who claimed that the printed product was not exactly in the same color as the actual product itself. It was considered to be detrimental to the company’s image and even to the company’s order. We believe that the color deviation is acceptable. For this kind of situation, it should be said that this kind of deviation exists objectively and cannot be entirely attributed to the quality control of the printing factory. As we mentioned earlier, to be precise, the color of printed products cannot be exactly the same as that of proofing. In addition, ink deviations may also occur within the same printed matter. Proofing can only be used as a reference standard because it comes out first, and customers may be pre-emptive, thinking that proofing is good and right. For this kind of situation, we usually take into account the color of the product picture at the time of printing, then the color of other pictures, and finally the decorative color bars or color blocks. For printing samples for ordering, we would like to advise customers to add one underneath the printed matter: “The colors in this print are for reference only and the color is based on the actual product†to avoid unnecessary disputes.
4. Paper Errors: Due to the papermaking process, the brightness, thickness, and texture of the same paper produced by different paper manufacturers may differ. For example, the same gram of coated paper produced by Zixing, Daewoo and Jindong has different textures. Of course, the difference is not huge. Another example is Asia Pacific offset paper, the fineness and whiteness of paper is better than other domestic manufacturers, but the price is about 50% higher. In addition, the same grammage paper produced by the same manufacturer may have slight variations in the production process due to the difference in the time of manufacture, plus the acceptable errors and the like, the brightness, thickness, and texture are also different. In fact, in the label of each batch of paper bought in the printing factory, the paper mill made such a statement in advance, and asked that it could not be mixed with the previous paper, so as to avoid deviations in user comparison. For a printing factory, it is necessary to provide the customer with the printed product paper pattern to be used before each printing, which is confirmed by the customer and then put into print in order to avoid such disputes.
5. Printing machine error:
The error in printing machinery is reflected in two points. One is the overprint accuracy problem, and the other is the ink problem. We know that color printing is actually four-color overprinting, that is, red, yellow, blue, and black colors are superimposed on one another, and overprinted content is reflected on film, which is the dot we mentioned earlier. In layman's terms, it is one by one. Dots. According to China's printing machinery industry standards, printing machine registration accuracy, which is the overlay accuracy requirements of the network point is 0.033mm, the actual mechanical accuracy is generally higher than this standard, mostly 0.01mm, of course, some printing machinery is 0.1mm ( Mostly monochrome machines). But even so, if you look at the printed product with a 40x magnifying glass, you can still see that the overlap of dots is deviating. Therefore, in the process of transfer of printed products, we can only reach the point where there is no problem with the naked eye, unless the printed product is a rare treasure of the millennium, or the printing factory can not accept the customer to take a magnifying glass to pick faults. For the problem of ink color, there is also a certain deviation due to ink compensation of the inking device. This has already been discussed in the previous section, and will not be repeated here.
6. Cutting size error:
After printing is completed, the next important step is to use a paper knife to cut the printed product. When cutting a finished product, the error after cutting the finished product is also objective because of the error of the cutter itself. In fact, according to relevant national standards, in the case of printed RMB products, the margin of error of the cutting size is 0.5 mm, and the margin of error of securities printed matter is 1 mm. In other words, the size of RMB and circulating securities is not exactly the same, but its error must fall within a certain range. For general prints, the dimensional error of cutting is mostly 2 mm above and below.
7. Psychological expectation error:
To be precise, the psychological expectation error should not be attributed to the category of printing errors that we discuss. The reason why this issue is mentioned is because we are dealing with customers. This problem is a problem that we often encounter, that is difficult to solve, and that we have to face. For customers who have long been in contact with printed matter, after long-term experience and knowledge accumulation, what kinds of errors are acceptable and what errors are unacceptable have already provided insights that are right and wrong, and it is easier to communicate with printing companies. However, some customers may have very high psychological expectations when making prints and they hope to make prints beautiful. For this part of the customer, the printing factory will take on the task of educating and training the market and communicate with customers. After all, print is print, not art. Poor communication is an unpleasant memory for both parties.
