– When using solvent and UV inks with strong destructive power, the harder the printing knife, the higher its resistance to solvents, thus limiting the swelling of the knife due to the impact of solvents.

– Hard printing knives are suitable for using automatic printers with high printing speed and printing force, soft knives are suitable for hand printing or semi-automatic printers where printing speed and printing pressure are smaller.
