further, the step (7) winds the elastic transition layer, and the surface of the wound elastic transition layer is coated with the prepared resin formula.
The invention has the beneficial effects that:
1. the standardization of the flexographic printing is realized, and the user does not need to select any adhesive tape or liner combination to stick the printing plate, which causes headache.
2. The requirements of screen mesh plate adjustment and solid plate printing can be met simultaneously, namely highlight small screen dots and solid color blocks can be printed on the same printing plate simultaneously.
3. Can effectively control the dot enlargement and obviously improve the printing quality.
4. The wear to the printing plate can be reduced, and the service life of the printing plate can be prolonged.
