Polyester screen mesh can be printed not only on hard objects but also on soft objects, and it is not limited by materials. In addition, the polyester screen mesh can be printed directly, or indirectly by printing. If necessary, that is printing on gelatin or silicone plates and then transferred to the substrate. Therefore, it can be said that polyester screen mesh printing has strong adaptability and a wide range of applications.
Polyester screen mesh can use a variety of inks and coatings, not only can use slurry, binder, various pigments but also can use thicker pigments. In addition, the ink used in polyester screen mesh is simple to prepare. For example, light-resistant pigments can be placed directly in the ink, which is another major feature of polyester screen mesh printing. Polyester screen mesh printed products have great advantages in light resistance.
In general, the maximum printing size of printing areas such as offset printing and embossing is full size, if it exceeds the full size, it will be limited by mechanical equipment. Polyester screen mesh printing can be used for large-area printing, and the size of the printed product can reach 3 meters × 4 meters or more.
Here are some details to be aware of for polyester screen mesh printing.
1. The printing place should be clean.
2. High-precision printing of printed circuit boards and electrical components. The printing workshop and the plate-making workshop must be clean, and there must be no dust in the air. If necessary, air purification equipment should be installed to maintain air hygiene in the workshop.
3. Temperature and humidity also have a certain effect on printing accuracy. Especially the effect of multi-color overprinting is more obvious. Therefore, the indoor humidity and temperature are required to be relatively stable. And adjust the indoor temperature and humidity according to seasonal changes to ensure the accuracy of printing size.
4. According to the requirements of the product itself and printing, choose a suitable polyester screen mesh that is should be suitable. The exposure time is determined according to the actual situation, and the exposure amount is determined according to the exposure experience.
