In the process of silk-screen silicone printing on textiles, choosing the right mesh printing is crucial, which directly affects the printing effect and the fineness of the pattern. Here are some suggestions on how to choose the right mesh printing:
1. Understand the concept of mesh number
The mesh number refers to the number of mesh holes per inch (2.54 cm) in length, which determines the fineness of the screen. The higher the mesh number, the smaller the mesh hole, and the finer the printed pattern; conversely, the lower the mesh number, the larger the mesh hole, and the coarser the printed pattern.
2. Choose the mesh number according to the fineness of the pattern
Fine pattern: If you need to print fine patterns or texts on textiles, such as trademarks, logos, etc., you should choose a high mesh screen, such as 200 mesh or higher. This ensures that the lines of the pattern are clear and the details are complete.
Simple pattern: For large areas, simple patterns or background colors, you can choose a low mesh screen, such as 60 mesh or 80 mesh. This can improve printing efficiency while ensuring the uniformity and consistency of the pattern.
3. Consider the fluidity of silicone
The fluidity of silicone is also an important factor in choosing the mesh number. Silicone with better fluidity is suitable for using a high-mesh screen, because a high-mesh screen can better control the flow of silicone, avoid overflow and leveling, and thus maintain the three-dimensional sense and clarity of the pattern. On the contrary, silicone with poor fluidity is more suitable for using a low-mesh screen.
4. Combined with printing process and equipment
When choosing the mesh number, the requirements of the printing process and equipment should also be considered. For example, manual screen printing may require more flexible screen selection to adapt to different operating methods and strengths; while mechanical screen printing may require a more stable screen to ensure the consistency and accuracy of printing.
5. Precautions
Measurement accuracy: When selecting a screen, ensure that the mesh number is measured accurately. Tools such as microscopes and mesh densitometers can be used for measurement.
Compatibility test: Before actual printing, it is recommended to conduct a compatibility test to verify the compatibility of the selected screen with materials such as silicone and textiles.
Experience accumulation: Through long-term practice and experience accumulation, the impact of different mesh numbers on printing effects can be more accurately judged, so as to make a more appropriate choice.
In summary, choosing the right mesh count is crucial for silk-screen silicone for textiles. It needs to be considered comprehensively based on many factors, such as the fineness of the pattern, the fluidity of the silicone, the printing process and equipment requirements, and precautions.
