  • Crack while scoring the sheet

    We printed shopping bag using Komori HUV Machine. We used Metallized sheet for the job. We did tape test to test the ink drying during the printing. But after printing during creasing crack appeared in fold areas. How to over come this problems as we are specially brought HUV machine to print packaging jobs

      Probably not the ink, probably the substrate. It can be alleviated, once you are 99.44% sure and confident that it is not the ink.

        Scoring the printed sheets dependably helps, and ought to be made arrangements for all stocks that are thicker. Will it dispose of all splitting? The genuine answer is NO, yet scoring will limit the potential. By changing the width of the score govern and channel, the odds for a perfect overlay are moved forward.

          Tape test only tests for ink adhesion to a substrate not ink cure. you need to perform other tests.
