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 with 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.
