3. Because the ink is more thin, so in choosing the use of the screen should choose high mesh, and the rubber hardness should be partial hard, can be more than 80 °.


4. The tension of the screen is slightly lower, the spacing of the net is also adjusted, and the scraping pressure of the scraper should be reduced properly so as to make the mirror effect happen.
