How to ensure the printing effect

When printing color boxes, many conditions will affect the quality of printing. It is not easy to maintain a pass rate of more than 99%. There are also many influencing factors, such as: printing equipment, paper materials, environmentally friendly inks used, printing temperature, technical ability of the operator, etc., a good reputation is created step by step. For digital 3C packaging customization, we use branded paper sources, using more than 100 advanced printing equipment imported from Germany, Switzerland, the United States, Japan, France and other places. At present, the operation of the printing workshop is mainly responsible for nearly half of the captain’s average working experience of 20 years, technical and Experience. Adopt international G7 color management and 24-hour operation to ensure that our quality and delivery meet the standards. How to achieve quality standards? First of all, it is necessary to change the quantity control. For example, the following 9 quality controls are the main points of attention.

1. Thin paper printing: Thinner paper is more difficult to print. Thin paper below 80G is easy to wrinkle during printing. The machine speed is required to speed up the plate, and the printing machine speed should be adjusted appropriately during printing.
2. Thick paper printing: more than 250 grams is called thick paper, and it is easy to shift the position when printing on thick paper. For the so-called thicker paper, the large suction machine should be adjusted to the appropriate suction volume while the slow machine is running during printing, and the adjustment should be carried out according to the actual situation on the spot. When printing on thick paper, the printing press has a relatively large loss, and the operator must follow up and observe, and properly dispose of it according to the detailed situation of the consumer site to avoid unnecessary losses.
3. Printing plate debugging: The operator is more critical, and must be careful and attentive to operate to ensure the balance of the force of the paper feeding department to push the cardboard, and layout manufacturing, assembly, and correction are also key. The layout position is positioned to meet and fit all aspects of the printing plate as much as possible. The conditions are sufficient.
4. Printing ink: The printing machine speed is too fast, the ink is not dry and the printed matter is heavily piled up, which will cause the offset printing ink to copy, penetrate, double image, overprint and other phenomena. The slippage will also constitute a slippage phenomenon. The phenomenon of printing is also more serious. The above-mentioned results are very rare, easy to deal with, and completely avoidable.
5. Poor resolution: make preparations for printing before the printing plate. Everything must be prepared such as: printing materials, verifying various data of the printing machine, adjusting the ink layer of the ink roller, the movement pressure of the roller, the speed of the printing machine, etc. . To stop synchronously, to ensure the quality of digital 3C packaging printed matter.
6. Printing strength: printing presses should avoid ultra-thick paper printing and full-page printing, and it is not easy to control the loss of the printing machine. Ideally, when printing products with more than 350 grams of paper, many printing factories are not happy to take orders and still have full-page printing. Printing is hard to control. We know that when the picture book is printed, the corrugated cardboard is transferred to the slotting part through the paper guide rollers and printing rollers of the printing machine. After the cardboard is pressed by the rollers during the transfer process, its physical properties have undergone varying degrees of changes, affecting To the strength of digital 3C packaging, when encountering this type of printed matter, reliable operation measures must be taken during the operation process to alleviate the negative effects and impacts.
7. Color correction: batches have no color difference, printing inks require authentic colors, bright and bright pictures, but these results are also related to the quality of the paper. The pictures printed on high-quality paper are more bright and bright, and Ink contains heavy chemical components, it will produce different chemical reactions in different environments, such as: humidity, temperature difference, high pressure, etc., so it will also cause abnormal changes in the printed album, remember.
8. Pre-press trial version: It is an important sequence before the formal printing. Ordinary companies or manufacturers will directly cooperate with the color matching, otherwise, the operator will need to use the printed version as the standard for color matching, and undergo multiple corrections. Later, the confirmation and print version did not have the tendency to be officially put into printing.
9. Subsequent part-time work: You must pay attention to loading, filming, indentation, and nailing. Any subsequent part-time work is very important. It is conceivable that the job at this time will affect the whole situation, that is, even if you are in front of you No matter how good the part-time job is, the next one who is not careful will lead to a one-sided part-time job in vain, so every process of digital 3C packaging custom printing should be completed in detail.
