One of two primary types of gravure cylinder in which the shafts (which are used to hold the cylinder in the press, engraving device, or elsewhere) are not manufactured as part of the cylinder base. The shafts for a sleeve cylinder must be inserted into bores located on either end of the cylinder. A sleeve cylinder is less expensive than a shaft cylinder, but due to the fact that different shafts are used for different stages of cylinder engraving, preparation, and printing, small inaccuracies inherent in each different set of shafts may not be compatible with those in another set of shafts, producing somewhat lower quality images. A sleeve cylinder is also called a mandrel. (See also Shaft Cylinder.) See Gravure Cylinder.
