Printed matter enriches our life and brings convenience to our life. However, in Luxury packaging boxes printing, some colors are very difficult to print and difficult to control.
1, gray balance, according to theory and production practice experience, the most difficult color to control print is gray balance. Gray balance is under a certain printability, yellow, magenta, green three primary color plate from light to deep according to a certain dot ratio combination overprint to obtain different brightness color, that is, to get the visual neutral gray color. There are many factors that affect it, and the amount of ink used in printing, paper, full plate concentration, dot area, overprint and the number of screen lines will have an inextricably influence on the gray balance.
2, 4 color over the net and 3 color over the net, full color do not print.
3. People who don't know how to print design things that are the hardest to print. Color is on the one hand, too many multi-color pole line thin, very small word transparent white and so on.
4, C=50M=50Y=50K=50 large flat network, a little inaccurate color is serious.
5, the text is four-color, that is, there are words in the four colors of cmyk, especially small words, it is difficult to put on, and the machine's paper teeth are extremely demanding. Therefore, the prepress designer must check the black text in the publication file before output, especially the small print, is not only on the black edition, and should not appear on the other three-color edition. If it appears, the quality of the printed product will be greatly reduced, and when the RGB graphics are converted to CMYK graphics, the black text will definitely become four-color black.
6, the black base is not good to deal with, the black bottom in order to achieve the effect can use extra black ink or printing twice, it is not difficult to print, more time-consuming.
7, several color network superposition, especially more than 70% of the network. For example, dark brown, brown, dark green (flat net, containing blue 70), dark blue, purple blue, etc. are difficult to find balance on the printing machine due to the color difference, so they are difficult to print colors.
These are the colors that are difficult to printin Luxury packaging boxes printing introduced by Xiaobian. You can simply understand them. For Hexing printing, no matter in the difficult brush, we can do it well. Because we have advanced equipment, rich experience and strong strength, we will make you satisfied!

Fault diagnosis principle first external and then internal, with the continuous improvement of the control system of EDM machine tool, the probability of failure in the control part is getting smaller and smaller. Most of the failures are not caused by the single-board machine or other core parts of the control and trigger circuit, but due to the damage of external circuits or devices. Therefore, maintenance personnel should start from the outside and gradually investigate the inside. Do not disassemble randomly. characteristics of cnc wire cutting machine Common fault diagnosis and troubleshooting methods characteristics of cnc wire cutting machine Fault diagnosis principle first external and then internal; With the continuous improvement of the control system of the EDM machine tool, the probability of failure of the control part is getting smaller and smaller, and the majority of the failure is not caused by the single board machine or other core parts of the control and trigger circuit, but due to the damage of the external circuit or device. Therefore, maintenance personnel should start from the outside and gradually investigate the inside. Do not arbitrarily remove the trigger circuit board, change the system parameter Settings, arbitrarily adjust the operating mode, etc., which may lead to new faults.
First mechanical after electrical, EDM machine tools are prone to mechanical failures, and these failures are often not easy to be found, and the failure caused by wearing parts is a typical example. Therefore, maintenance personnel should focus on the local scope of failure, first start from the mechanical part, carefully observe, and carefully investigate the fault, such as whether there are cracks, loosening, breakage, fragmentation, etc. Instead of immediately checking whether the circuit is open, short circuit, whether the components are damaged and other electrical faults.
After theory and practice, the control circuit of the EDM machine tool is relatively not too complex, which makes some maintenance personnel do not look at the schematic provided by the manufacturer, do not analyze the root cause of the fault, and blindly carry out live maintenance operations, which will lead to further expansion of the fault. On the basis of understanding the fault situation, the maintenance personnel should carefully analyze the cause of the fault, theoretically clarify the method to solve the fault, and then put it into practice.
First simple and then complex, some failures are caused by a variety of factors. At this time, you should follow the first simple and then complex procedures, solve the small fault first, properly handle these hidden dangers, and then solve the difficult fault. When solving a difficult fault, it should also be broken into pieces, first solve its simple part, and then deal with the complex part. Often after the simple problem is solved, the difficult problem may also be solved.

A friend will print the book and envelope to a printing house theory, the reason is that the production of the book cover cutting are missing the phenomenon of white edges. At that time, the friend was very angry, and the printer felt that he was very wronged, because they had been very careful when cutting, the main reason was that the friend did not know how to reserve the bleeding position when designing, and the printing company did not do its duty to remind the department of the need to reprint the situation.
polyester sublimation paper factory What is the bleeding position?
Album printing and other printed matter after printing, there will always be how many irregular edges, these must be cut off, so in the design time should be reserved for a certain width, this is the bleeding position, the Great Wall printing suggested that designers in the design of printed matter, Try to leave 3mm outside the finished product size (some special cases may want to leave more) You can also directly consult the Great Wall printing customer service, of course, under normal circumstances when we receive the customer's document, will carefully check. When you encounter a document that does not leave a bleeding spot, it will remind you, or assist the customer to correct the document. In addition, the advantages of setting the bleeding position are also manifested in: 1. Reduce the difficulty of post-printing processing, such as cutting
Industry, big plate work, etc. 2. For cross-page printed matter, the integrity of the printed picture can be achieved.
Of course, different prints have different requirements for bleeding sites, and it is not always possible to leave more bleeding sites and reduce the size of the finished product. For example, for single-sheet printing, posters, due to each
All four sides of the page have to be cut, so all four sides have to be set to bleed. For example, every 2 pages of corporate picture albums and magazines are a piece of paper, and the binding line is located in the middle of each paper
On the side where the stitching is located, do not set the bleeding, just set it on the other 3 sides. If you still have questions about the bleeding position, contact the Great Wall printing customer service, we directly answer for you can make it easier for you to understand
