Key points of flexo plate making process
1 Try not to put a large area on the same plate with small characters, dots and other details. Even if it is of the same color, try to divide it into two plates. If it is impossible to separate, you can consider partial pad
2. Try to avoid large-area solid block multicolor overprint
3. The text specification should not be too small, especially the Yin text. Otherwise, when the pressure of the printed matter changes, the printed graphics and text will show a large amount of deformation, making the Yang graphics and text thicker can make our foundation evergreen, and the Yin graphics and text thin or paste
4. The width of independent thin lines should be greater than 0.2 mm
5. In flexographic printing, the engraving angle of the inking hole on the grain transfer ink roller is generally 45 °. When using the ordinary grain transfer ink roller for printing, the printing plate should avoid using a 45 ° line angle to avoid the appearance of moire
6. Avoid designing wide and long bars and fields along the horizontal direction of the printing drum. Ideally, slashes, curves, wavy lines and other irregular curves are preferred
7. Avoid designing large circular patterns on the layout. Because when the printing plate is elastically stretched or elastically compressed, the regular geometric pattern will become irregular, and the circle will become an ellipse
8. Avoid the precise overprint requirements of tight fitting
9. The color setting of the original should take into account the non Newtonian fluid characteristics of the printing display; 5. How many colors can the two-time processing machine print at most. When using the ink stacking depth to meet the entrepreneurial needs, it is not suitable to use two color blocks of equal size to overprint. You can use local overprint words or patterns and local color blocks on a large area of field color blocks
