As one of the four major inventions in China, printing has developed into an indispensable technology. The ease and breadth of culture and knowledge dissemination depends primarily on the printing industry. As people's demands and requirements for books become higher and higher, the technology of printing technology is becoming more complex and efficient. As a part of the traditional printing process, the plate printing machine directly affects the printing effect and quality. The printing machine control system plays an important role in the normal operation of the printing machine. At present, the printing machine has become a must-have for high-end color printing. This article will introduce you to the silk screen printing machine.
The working principle of the printing machine: the film and PS version are closely attached, and then exposed to ultraviolet light. The quality of the sounding version has two main points: the vacuum, the closeness of the film and the PS version. The source of light, the wavelength of the ultraviolet light is within a certain range, as much as possible "pure". The closeness of the original (such as film) and PS version fit.
The printing machine occupies an extremely important position in the prepress equipment, and its performance directly affects the quality of the plate making, and its maintenance plays a decisive role in the printing production process. If the correct selection, proper maintenance and timely maintenance of the required printing machine can not only improve the service life of the printing machine, but also improve the quality of the printing plate. The temperature rise of the working glass surface of the plate printing machine should be no more than 20 °C. Detection method: the exposure light source is placed in the normal working position, and the surface temperature of the working glass is measured by a point thermometer having a division value of not less than 0.5 °C.
Compared with the LED digital tube, the printing machine has great advantages, and can freely edit the true color picture, which can achieve animation effects. The PLC-based control system is more advanced and more user-friendly than the older models in terms of interface friendliness and functionality.

When it comes to removing unwanted hair, you have options. With so much misinformation available about these options, it can be difficult to know which one(s) is best for you. To help you make an informed decision, here are the basic facts that dermatologists share with their patients about 7 popular ways to remove unwanted hair.
Shaving
When you shave, the razor cuts the hairs at the surface of your skin so that you cannot see the hairs.
Fast facts: Here are the long and short of shaving:
You can shave any area of the body.
You can quickly learn how to shave.
Shaving is painless (unless you cut yourself), unlike waxing or laser hair removal.
The results are short-lived, so you may need to shave daily or every few days to maintain your results.
Frequent shaving can irritate your skin.
Injuries, such as cuts, nicks, and razor burns, happen.
Some people who shave develop ingrown hairs.
How to get the best results: The following tips from dermatologists can help you reduce injuries and get a close, comfortable shave.

Waxing
You apply wax (hot or cold) to your skin and then quickly remove it, which pulls out the hairs.
Fast facts: Here are the cold facts about this option:
The results can last a few weeks or longer.

Your newly waxed skin can be red and irritated for a short while after you wax.
If the wax is too hot, it can burn your skin.
How to get the best results: These dermatologists` tips can help you keep it safe and effective:
Waxing is not recommended if you are currently:
Taking isotretinoin (a prescription medication approved to treat severe acne) or have taken it within the past 6 months.
Using an antibiotic
Applying tretinoin (also known as retinoic acid) to your skin.
These medications thin your skin. When the wax is removed, your skin could tear.
If you wax at home, be sure to see what dermatologists recommend by watching this short video, Hair removal: How to wax.
If you go to a salon for a wax, make sure the estheticians:
Use wooden sticks rather than a metal spatula to apply the hot wax.
Dip an unused wooden stick into the wax each time they apply wax to your skin.
Dipping the stick into the wax more than once is called double dipping. This unsanitary practice can transfer bacteria and other germs from previous clients to you. Heated wax is not hot enough to kill bacteria and other germs.

Fast facts: The following can help wash away any misconceptions about using a depilatory:

Some people can use a product for months or years before it starts to irritate their skin.
Some people dislike the odor of these products.
How to get the best results from a depilatory: Always, test first. Before using a depilatory for the first time or using it on a different part of your body, here`s how to test the product:
Apply a small amount to an area on which you want to use it.
Keep it on your skin for the time stated in the instructions (or until your skin starts to burn or sting).
Rinse it off immediately and thoroughly at the time stated or at the first sign of burning or stinging.
If you experience burning or stinging, don`t use the product. Find another depilatory to test.
If within 24 hours of applying the product you don`t have a skin reaction, you can use the product in that area.
