A gravure printing unit, which is usable for printing on a substrate, according to a gravure printing method, includes a forme cylinder which comprises, on its circumference, an image-forming pattern of recesses, and an inking unit, by the use of which the pattern of recesses provided on the forme cylinder is inked. The forme cylinder can be partially inked from an inking device via a first inking unit cylinder which has recesses in the region of its outer cylindrical surface that correspond to recesses on the forme cylinder, and via a second inking unit cylinder, which cooperates with the first inking unit cylinder and which comprises ink-transferring elements or raised areas on its circumference. For controlling the transfer of ink, the first inking unit cylinder having the recesses, is configured as being temperature controllable or has a temperature control device in the ink unit supply. Alternatively, a printing pressure between inking units cylinders can be varied during operation. The invention also relates to a method for adjusting or modifying a transfer of ink and for operating the gravure printing unit.
