1. Polishing squeegee
After the new squeegee is installed on the machine, it must be polished back and forth with sandpaper, polished with 800 mesh, first from the front and then from the side, back and forth 20 times, after polishing, use the nail cover to glide, take a look Is there a gap? Pay attention to playing? A good scraper should be smooth and free of gaps. Pay attention to find subtle problems, which may cause knife lines.
2. Install and lock the scraper
Before installing the squeegee, pay attention to clean the lining knife and the knife board, there must be no trace of ink or stains, so as to avoid uneven knife installation and wavy shape. After installation, tighten from the middle. Be careful not to over-tighten at first. Lock slightly and then back and forth on both sides.
At the same time, the scraper should be kept straight, otherwise waves will appear. Pay attention not to lock the screws too tightly, as it is necessary for the next step. After locking the screws, you should pay attention to whether the height of the three points is balanced. You can't measure the height at the same time. You can use a special ruler or use one end of the hexagon to measure. The height of the three points must be the same.
If it is an old squeegee, you can use a special whetstone to grind the squeegee. This requires special training.
Ink must be filtered, filtered before going to the machine, use an ink pump to circulate ink, hang socks at the outlet of the ink basin to filter.
At the same time, the squeegee of the field version (such as the text version) should be harder. The squeegee extends 2-3 cm from the blade liner. The shallow screen version should be softer. At 3-4 cm, the squeegee angle should be 45-60 degrees. The position of one stop must be centered when cutting the knife, and cannot be deviated.
3. Squeegee down
The method of pressing down the doctor blade is as follows: first shake the doctor blade to a height of about 3 cm from the surface of the plate roller, and then reduce the pressure of the doctor blade to the minimum. After closing the doctor blade and lowering the knife naturally, adjust the pressure back to not exceed 0.25MPA. This can effectively maintain the elasticity of the scraper.
After the squeegee is down, turn on the equipment at the normal printing speed, and observe the printing status of each layout with the strobe light. If there is a knife line, if it is, you can sand it out first to facilitate production.
4. Measure printing viscosity
Before starting the machine, it is necessary to pay attention to the measurement and control of the printing viscosity. This is very important, and it is also one of the important ways to control the appearance of the knife line.
5. Other matters needing attention
In addition: after installing the plate, it is necessary to pay attention to the idling for the plate throwing. The C-type action is used, and the screen is evenly thrown back and forth with 800 mesh sandpaper. Be careful not to use too much force, it is best to stick solvent or water on the sandpaper for tossing.
For the full version of the layout, you can use the old blade to produce, you can use the back of the knife to produce, don't forget to use sandpaper to polish it before use, this can effectively save the scraper.
After printing the product, please pay attention to wipe it with solvent in time, this should be done immediately. If the shutdown does not start, the scraper should be removed in time, cleaned with solvent, brushed with oil and wrapped with PET white film, and the logo should be spared, so as to effectively save the scraper.
powder brush:The use of loose powder requires a powder brush. The final step of setting makeup as a base makeup is to use the characteristic of loose powder as a dry powder to absorb excess moisture and oil on our face and make our base makeup more durable. The texture of the bristles of the loose powder brush is very soft and elastic, and the pressure on the face will not be very strong, which can help us sweep away the excess loose powder and make the entire makeup look more compliant and clean.Common types of powder brush:Setting Powder Brush,Powder Brush For Foundation,Foundation Powder Brush,Makeup Powder Brush,Best Powder Brush
