What problems should be paid attention to before printing?

In addition to the preparation work, other relevant problems should also be paid attention to before screen printing. Attention should be paid to the following aspects before printing.

① Cleaning screen printing in printing places with the continuous improvement of printing precision requirements, special printing circuit boards, electrical components and other high-precision printing, also put forward higher requirements for the environment. Generally, the printing workshop and plate-making workshop must be clean, and there is no dust in the air, otherwise it will affect the printing quality. For the workshop with high printing accuracy requirements, air purification equipment should be installed when necessary to keep the printing and plate making workshop clean. 

② Temperature and humidity in spring, summer, autumn, winter temperature and humidity changes greatly, the impact on printing accuracy is relatively large, especially multi-color overprint, the impact is more obvious, so, the indoor humidity, temperature to be relatively stable, and according to the seasonal adjustment temperature and indoor humidity, in order to ensure the accuracy of printing size. 

③ Fully understand the properties of the substrate because of the screen printing application range is very wide, a wide variety of printing materials, and the shape of the substrate is also different, before printing according to different requirements to choose the appropriate ink and solvent and scraper.
