  • Printed substrate and printing method
    Patent number: 7435473
    Abstract: The invention refers to a printed substrate comprising a substrate with an oleophilic surface having a Gurley-Hill permeance value bigger than 5000 s/100 ml, the ink printed on the substrate having an IGT ink set-off value bigger than 0.60 print density units at 30 s delay time. The invention also refers to a printing method performed in at least one printing unit under use of following substrate/ink combination: the substrate has an oleophilic surface and is non-porous, i.e. has a Gurley-Hill permenace value bigger than 5000 s/100 ml, the pigment carrier/ink has an IGT ink set-off value larger than 0.60 print density units at 30 s delay time.
