Abstract
Sleeves with different circumferences (and hence print repeat lengths) are removably mountable on a roll core, making use of radial compressibility of the radially inner region of each sleeve. The radially outer regions are incompressible, to ensure good print quality. A sleeve may have inner and outer regions of different foam materials. Alternatively it may employ spaced discs having resilient arcuate tongues engaging an inner sleeve. An outer sleeve may be defined by slats engaging the discs, or peripheral flanges of the discs.
