[origin: WO2022174958A1] The invention relates to an ink supply system for providing a supply of printing ink (21) to an inking unit (07) of an intaglio printing unit (06). The system comprises an inking device (16) which is provided in the inking unit (07) and inks in particular a first inking unit cylinder (17), and a supply apparatus (26) having a reservoir (38) in which an ink supply (25) of printing ink (21) can be held and can be supplied to the inking device (16) via an outlet (46) and a line (34). To improve the metering possibilities, a reservoir (38) wall comprising the outlet (46) can be heated and/or, in addition to a conveying device (37) which supports and/or causes the conveyance of the printing ink (21) out of the reservoir (38), a metering device (27) is provided in the line path. The invention also relates to a method for supplying printing ink (21) to an inking unit (07) of an intaglio printing unit (06) and to an intaglio printing unit (06) and to a method for operating an ink supply system.
