For a specific substrate and a specific ink,the ink concentration is relatively fixed,the transfer rate depends on the viscosity of the ink, dryness , the layout of the net hole conditions and other factors.It is also affected by printing speed, printing pressure, scraper pressure, scraper position, scraper Angle,environmental conditions and other factors.It needs to be pointed out that the changes of these conditions will have varying degrees of influence on printing highlights, dark and middle tone.
Compared with the common easy-open lid, aluminum foil easy peel film in production has the advantages of simple process, easy to assemble, save materials and so on.
