There are three points to note before silk screen processing:
- Clean the printing place of silk screen processing on plastic bottles. Try to ensure that there is no dust in the air in the printing workshop and plate making workshop, otherwise it will affect the printing quality. For workshops that require high printing accuracy, air purification equipment should be installed if necessary to keep the printing and platemaking workshops clean.
- The temperature and humidity requirements, the temperature and humidity of the four seasons vary greatly, and the impact on printing accuracy is relatively large, especially the multi-color overprint, the effect is more obvious, so the indoor humidity and temperature must be relatively stable, and according to the season Properly adjust the temperature and humidity in the room to ensure printing dimensional accuracy.
- Understand the nature of substrates. At present, with the development of science and technology, there are many types of substrates and different shapes. Before printing, select appropriate inks, solvents, and scrapers according to different requirements.
