Claim 17:
18. A method for applying a first printing fluid and a second printing fluid onto at least one substrate (10) by use of at least one intaglio gravure printing press comprising at least one gravure printing unit, the at least one gravure printing unit comprising at least one forme cylinder (03) and at least one impression cylinder (01), the at least one forme cylinder (03) comprising at least one printing plate (02) including at least one engraving, the at least one intaglio gravure printing press further comprising at least one inking unit (18), wherein:
the at least one inking unit (18) applies the first printing fluid into the at least one engraving of the at least one forme cylinder (03), or
at least one ink collecting cylinder (12) having the at least one inking unit (18) arranged thereat, applies the first printing fluid into the at least one engraving of the at least one forme cylinder (03),
the intaglio gravure printing press further comprising at least one print head (04) that is positioned to apply the second printing fluid into the at least one engraving on the at least one forme cylinder (03), the method comprising:
applying, by the at least one print head (04), the second printing fluid into the at least one engraving prior to applying the first printing fluid into the at least one engraving,
applying, by the at least one ink collecting cylinder (12) or the at least one inking unit (18), the first printing fluid into the at least one engraving having the second printing fluid therein,
during printing, depositing concurrently the first printing fluid and the second printing fluid from the at least one engraving onto the at least one substrate (10), the second printing fluid forming, at least in part, at least one layer and/or at least one film on the first printing fluid deposited on the at least one substrate (10), the second printing fluid having a drying and/or curing behavior that is different from a drying and/or curing behavior of the first printing fluid.
