What preparation should you make before printing work?
Good preparation before printing, printing is an essential work smoothly.Before printing production need to be prepared for the following several aspects of the basic.
(1) clean up the printing area, ensure the printing machine or printing machine around a certain activity space operation, to avoid other objects interfere with work.Keep the site clean and avoid dust and affect printing quality.
(2) pay attention to adjust the printing workshop humidity and temperature, to meet the printing requirement.
(3) ready for the scraper, and check whether there is scraper, bruised if there were to be bruised grinding, to prevent scratch plate affect printing quality.
Check screen plate
(4), found that the problem timely correction, ensure around censorship on silk screen printing, and avoid the graphic part of the leak of a phenomenon.Cha layout gently with wet cloth, remove the dust on the screen.
5. According to the characteristics of substrates, adjust the screen plate with the appropriate gap between substrates.
6. Check the color and viscosity of the ink used is in accordance with the requirements.
All landowners according to size substrates, determine its position in the printing stage.Rules of the fixed printing auxiliary equipment.
Today completes the drying paper rack and other dryers, to adjust the drying temperature in advance.To be prepared for the above checks, can start the printing.
In addition, but also according to the actual need, the attention of the other related work.
What are the problems should be paid attention to before printing?
Silk screen printing in addition to prepare, before also should pay attention to other relevant issues.Before the printing should note the following respects.
(1) the printing place clean with silkscreen printing accuracy requirement improving, special printed circuit boards, electrical components and other high precision printing, also put forward higher request to the environment.General requirements, plate-making printing workshop must be clean, no dust in the air, otherwise it will affect the printing quality.The printing accuracy requirement high workshop, if necessary, to install air purification equipment, to keep the printing, plate-making workshop clean.
(2) the temperature and humidity, spring, summer, autumn and winter seasons change of the temperature and humidity is bigger, affect printing precision is relatively large, especially the polychromatic overprint, the effect is more apparent, therefore, requires a relatively stable indoor humidity, temperature, and depending on the season to adjust indoor temperature and humidity, to ensure that the printing size accuracy.
(3) fully understand the nature of substrates Because the silk screen printing application range is very wide, there are many different kinds of substrates, and the shape of the substrates is also different, according to different requirements to choose appropriate before printing ink and solvent as well as the scraper and so on.
