Intaglio gravure printing press and method for applying at least one printing fluid onto at least one substrate

A method for applying at ink and a protective 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 ink 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 ink 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 protective 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 protective fluid into the at least one engraving prior to applying the ink 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 ink into the at least one engraving having the protective fluid therein,
• during printing, depositing concurrently the ink and the protective fluid from the at least one engraving onto the at least one substrate (10), the protective fluid forming at least one protective layer and/or at least one protective film on the ink deposited on the at least one substrate (10), and
• subsequent to the printing, drying and/or curing, by at least one dryer (07), the protective fluid at least in part, the protective fluid configured to at least one of dry, be dried, cure, or be cured more quickly than the ink.

An 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), at least one impression cylinder (01), and at least one inking unit (18), wherein:

• the at least one inking unit (18) is arranged at the at least one forme cylinder (03) and provides a first printing fluid to the at least one forme cylinder (03), or
• at least one ink collecting cylinder (12) is arranged at the at least one forme cylinder (03) and the at least one inking unit (18) is arranged at the at least one ink collecting cylinder (12), the at least one ink collecting cylinder (12) providing the first printing fluid from the inking unit (18) to the at least one forme cylinder (03),
• the intaglio gravure printing press further comprising at least one print head (04), which is arranged at the at least one forme cylinder (03), and which is positioned with respect to the at least one forme cylinder (03) to apply a second printing fluid into at least one engraving on the at least one forme cylinder (03) prior to the first printing fluid being applied into the at least one engraving on the at least one forme cylinder (03) to enable the at least one forme cylinder (03) to deposit concurrently both the first printing fluid and the second printing fluid during printing onto at least one substrate (10), the second printing fluid forming, at least in part, a layer and/or film on the first printing fluid deposited onto 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.

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.
