Generally, any press smaller than 11 x 17in. (279 x 432mm) without bearers (hardened metal tings attached to the ends of the cylinder or to the cylinder's journal) is called a small offset press or, more often, a duplicator, Figure 3-6. Duplicators started out as office machines using the offset principle. The original duplicators were extremely simple, but they have developed into sophisticated offset presses that fill many printing needs. Many are being used for multicolor work.
The gap between "duplicators" and the more heavily built offset presses is being filled by some new presses. These have the simplicity of the duplicator plus many of the quality features of the larger presses.
