NOTE: The base material includes foil paper, i.e. aluminium foil laminated paper.

Products are shaped either as roll-type film wound on a specified winding core (hereafter referred to as "roll product") and sheet cut to make a flat-sheet type (hereafter referred to as "flat-sheet product").

NOTE: Metalized sheet or composite materials (laminated) can be used as the base material of the film.

Products are shaped either as roll-type film wound on a specified winding core (hereafter referred to as "roll product") and sheet cut to make a flat-sheet type (hereafter referred to as "flatsheet product").

This method describes testing with an amount of ink simulating either single colour or multi-colour printing. The print and the set-off print (counter print) are made with interval times, between print and set-off, common for the target process.

This method evaluates a particular ink and substrate combination.
