Adjustable diameter heated is a very precise mechanical component and it is also a core component of flexographic printing machines. Therefore, during use, one must be very careful to avoid bumps or damage.
Tips for choosing the appropriate adjustable diameter heated
1. Select based on the mesh line count of the printing plate
Then each dot on the printing plate must be accurately inked. To achieve this, it is necessary to ensure that the dots of each color level on the printing plate are accurately reproduced. The opening area of adjustable diameter heated should be smaller than the dot area, so that one or several ink injection holes can ink without allowing the dots to get stuck in the mesh holes, preventing the ink dots from expanding on the printed product.
2. Select based on the graphic structure
The higher the mesh line count, the less the ink transfer. For the same screen engraving process. It is more suitable for printing dots and fine text; while the lower the mesh line count, the more ink is transferred, and it is more suitable for printing large areas of color blocks and bold characters.
3. Select based on the substrate
When the ink transfer amount is large and the surface of the substrate is rough, a adjustable diameter heated with a lower mesh line count should be used; conversely, when printing on a substrate with a smooth surface, a adjustable diameter heated with a higher mesh line count and a smaller ink transfer amount should be used.
4. Select adjustable diameter heated based on different wear levels: When the ink injection hole volume of adjustable diameter heated reduces by half, it should be replaced with a new one.
5. Select adjustable diameter heated based on different ink delivery devices
