摘要： A cylinder (10) comprising a cylindrical body (11) is provided. A first proportion of the circumferential face (48) of the cylindrical body (11) is of porous and gas-permeable configuration and a second proportion of the circumferential face (48) of the cylindrical body (11) is of gas-impermeable configuration, wherein the porous, gas-permeable first proportion of the circumferential face (48) is in communication with at least one gas supply line and wherein the first proportion of the circumferential face (48) amounts to at least 0.1% and at most 50%. Further, a corresponding adapter sleeve and a corresponding printing forme cylinder are provided.
