A printing press is a type of printing equipment commonly used for printing text and images. Because the screen printing machine has the advantages of cheap price, long storage period, large batch, bright color, fast delivery, etc., it is recognized by more and more industries, and the application range is also very wide. The preparation work before the screen printing machine is done well, which can play a multiplier role for the screen printing work behind. Today Xiaobian share the main precautions when printing screen printing machine.
Precautions for screen printing machine before printing
1, the cleaning of the printing place of the screen printing machine, the printing workshop and plate making workshop to ensure that there is no dust in the air, otherwise it will affect the printing quality. For workshops with higher printing accuracy requirements, air purification equipment should be installed if necessary to keep the printing and plate making workshops clean.
2, screen printing on the temperature and humidity requirements, the four seasons temperature and humidity change greatly, the impact on the printing accuracy of the screen printing machine is relatively large, especially multi-color overprinting, the impact is more obvious, so the indoor humidity, temperature should be relatively stable, and according to seasonal changes to adjust the indoor temperature and humidity, to ensure the printing dimensional accuracy.
3, screen printing machine before printing to understand the nature of the substrate, with the development of science and technology, a wide variety of substrate materials, the shape is also different, before printing to choose the appropriate ink and solvent and scraper according to different requirements.
Precautions for operating the screen printing machine
1, can not make too much water and oil into the screen printing machine pressure system, to avoid cylinder failure and shorten the service life of the cylinder, to ensure the dry and clean compressed air;
2. Check whether the oil amount in the oil cup of the screen printer converter is enough every day, and the pressure relief valve should not be pushed at the back end for a long time, and it is best to install a freeze dryer if conditions exist;
3, when the screen printing machine stops working, the main power switch and compressed air source should be turned off; The cylinder of the speed control valve and the axis of each part should avoid magnetic loss;
4. The horizontal slide seat part of the screen printing machine table and the components with a high precision must be wiped clean and oiled regularly to prevent the precision from being affected by rust.
5, screen printing machine is printing, ink control. When printing, you need to control the ink speed, screen printing machine to ensure that the ink can be uniform, once on
6. Screen printing machine printing rate control. The printing speed of the screen printing machine can be controlled manually, and for the automatic screen printing machine, it can be set by itself and does not require too many personnel to operate.
7, screen printing machine printing, clean the printed parts. Screen printing machine, printing effect is good or bad, in addition to related to the equipment, but also related to the printed parts, printed parts if there is water, or dirty, will cause ink and other conditions, affecting printing, so before printing items, to do a good job of cleaning the printed parts.
8, the operation of the use of silk screen printing machine requires specialized operators, the use of operating equipment needs to be trained, trained qualified, before you can operate the mechanical equipment, to ensure that the mechanical equipment is not damaged.
9, when entering the compressed air, do not put any part of the body in the position where the screen printing machine can move, so as to avoid crushing injury.
10, if the screen printing machine cylinder action is too fast, the flow control valve in the direction of the movement is rotated clockwise to slow down its speed, if the action is too slow, vice versa.
11, screen printing machine screen printing process according to the ink drying situation from time to time to add an appropriate amount of oil and water to maintain the viscosity of the ink.
