In printing, how do we choose the same paper, the same ink, without considering other process problems, some card game printing wholesale luster difference is a lot, then if you do not use the film after printing then, There are also a variety of ways to improve the gloss of card game printing wholesale:
Luster, as a kind of visual information, can have an important impact on people's mental state, emotions and many other spiritual aspects, so people's research on color began very early. For customers, a certain commodity on a card game printing wholesale needs to have luster, except for the luster made by technology. So whether the light can be reflected in the printing, we also come to understand.
1, improve the acid edition solution.
It is mainly characterized by Ming acid and phosphoric acid. The stronger the acidity, the greater the resolving power of ink linking materials and pigments, and the greater the corrosion, resulting in the rough surface of imprinted film and the reduction of luster.
2, reduce ink emulsification.
The excessive emulsification of ink in offset printing is mostly caused by large amounts of water and ink in the operation, and the ink layer looks very thick, but the ink molecules become the state of oil in water, and the luster is very poor after drying, and it will also produce a series of other failures. Large ink is a more taboo practice in offset printing.
3, the appropriate additives in the ink.
The appropriate addition of auxiliary agents in the ink can adjust the printability of the ink, so as to smooth printing, most of the auxiliary agents will have an adverse effect on the gloss of the finished product, such as anti-stick agent, the main raw material of anti-stick agent is six grain powder, after adding ink, the surface of the imprinted film is rough due to the precipitation of corn flour, and the gloss of the finished product is poor.
4. Use dry oil correctly.
In the process operation, the correct use of dry oil is very beneficial to the formation of gloss in the finished product. This is because the paper takes a certain amount of time to absorb the binder, and in this process, the binder condenses as soon as possible until the conjunctiva is dry, which is the key to the finished product's good luster.
5. Watch the powder.
Spray powder, like ink, will also produce condensation, especially the bag or barrel that is not sealed well, after the spray powder is damp, it condenses into larger particles, and is sprayed onto the wet ink imprint, making the ink layer surface conjunctival rough, reducing the original luster, so the spray powder should pay attention to moisture resistance.
6. Adjust the machine properly. Whether the thickness of the imprinted ink layer meets the standard also has an impact on the gloss. For example, the pressure regulation is poor, the dot expansion rate is high, the ink layer thickness is not up to standard, and the finished product luster is slightly poor.

servo upside down special machine parking problem treatment ideas, do you know? The spindle of the digital lathe is parallel to the horizontal plane, and the circular table with a large diameter is used to clamp the workpiece. These machines are mainly used to process large complex parts with large radial size and relatively small axial size.
Digital lathe parking problem phenomenon: digital lathe parking will make a big sound, while the workshop power supply trip. First, the shop electrician checks the power supply system to check the location of the traveling air circuit breaker. Because the link mechanism of the active trip in the ambient moisture switch box is corroded, one of the other three phase contacts can only contact a small part. Second, the workshop power transformer capacity is small, overload work. Normal phase voltage is only 340V. Finally, a thyristor on the digital control rack is burned, check the drive circuit, the trigger pulse is shorter, as long as the normal trigger pulse width is one-fourth, it will be confirmed that the amplifier tube of the trigger circuit is not functioning well.
Defect analysis: The result of insufficient phase of thyristor under rectified state is different from that under reverse change. In the case of rectification, the thyristor with high potential is always triggered, and the previous thyristor withstands the reverse voltage and is disconnected. In the shutdown process of thyristor, the reverse phase blocking state is the main one. Even if the latter thyristor is not triggered, the thyristor will actively shield over a certain period of time. However, in the case of stopping and slowing down, that is, in the case of reverse change, the same thyristor with higher triggering potential is conductive, and if the previous thyristor is closed under reverse pressure, it will be in a positive closed state for a long time when the thyristor is closed.
In this way, if the last thyristor is blocked, due to the discharge action and effect of the inductance, the thyristor will recirculate once, and the thyristor will continue to pass under the positive accompaniment. And interfere with the thyristor conduction behind. Therefore, the forward voltage output by the thyristor overlaps with the motor potential, producing a large current, which reverses, burns the fuse, and re-burns the thyristor. The voltage power supply system in the digital lathe shop is normal and may not burn the thyristor if there is no large shaking. Due to the communication network voltage fluctuation, the workshop transformer capacity is small, overload work, the upper shaft group trigger pulse width is small, the workshop power system main switch box damage and other comprehensive reasons, the fault occurred.

24 inch electric hedge trimmer plays an important role in agricultural production. They are used to turn soil, level land and open ditches, and are essential tools for farmers. The 24 inch electric hedge trimmer is a very complex component, and the blade is just a part that can not be underestimated. After all, whether it is digging or ditching, the blade is needed, so the proper cleaning and maintenance of the 24 inch electric hedge trimmer blade is essential. It can extend its life and improve work efficiency.
To clean the blade, perform the following steps:
Step 1: Remove the blade from the head. If the blade is heavy, use a rack or bracket to hold it in place.
Step 2: Use a scraper or stiff brush to remove dirt and debris from the 24-inch electric hedge trimmer blade. Note that the sooner dirt is removed, the easier it will be to clean up.
If a scraper or brush doesn't work, use a high-pressure water hose to clean the blade. However, it should be noted that do not spray water in the direction of cables, fuel or sensitive parts of the machine.
Step 3: Place the 24-inch electric hedge trimmer blade in a clean area and dry it for further maintenance.
The steps to maintain the blade are as follows:
Step 1: Clean the rusted area on the blade with a stone. If you can't completely wipe it with sandpaper, you can use a stiff brush and some lubricating oil to wipe it.
Step 2: Check whether the edge of the blade needs to be sharpened again. If the edge has become dull, the knife needs to be sharpened again. The blades are ground using a specialized sharpener and impact vacuum cleaner.
Step 3: Wipe the 24-inch electric hedge trimmer blade clean and apply protective oil to prevent rust. For protective coatings, high temperature rich lubricants can be used, and even small sprayers can be used for spraying.
Of course, proper cleaning and maintenance of the blade is not enough, but also need to pay attention to the following points:
1, use the correct 24 inch electric hedge trimmer: Ensure that the 24 inch electric hedge trimmer and 24 inch electric hedge trimmer work well together. Using a poorly used 24 inch electric hedge trimmer may cause the 24 inch electric hedge trimmer blade to wear out faster.
2, proper storage: Store the blade in a dry, suitable temperature place. Try to keep the 24 inch electric hedge trimmer blade in the blade case and store it in a storage room or cabinet.
3, pay attention to maintenance time: to regularly check the wear of the blade. If the blade is worn, replace it in time.
Cleaning and maintaining a 24 inch electric hedge trimmer blade is a very important task, and with the right cleaning and maintenance methods, you can extend the life of the blade and improve the efficiency of the job. Therefore, farmers should pay attention to the importance of cleaning and maintaining blades to ensure that the blades used are in a sharp state.
