Small offset presses usually refer to offset presses with printing formats of A3, B3 and below (generally the format is equal to or less than 520mm × 360mm).
In addition to being classified according to the paper size, small offset presses are usually classified according to their uses, which mainly include the following categories.
Business card (desktop) small offset printing machine: usually placed on the table, so it is called desktop small offset printing machine. Originally designed for office document printing, it is now mainly used for business card printing. Its structure is simple, its performance is single, and its printing quality is average.

There is usually only one row of suction nozzles to feed the paper directly to the paper. The paper belt and the center line of the machine have an angle, and the side of the paper is positioned by the side of the cardboard. Paper collection is also very simple. Generally, there is only one inclined paper collection hopper, which is mainly used for office document printing. It can also be used for single-color or two-color rapid commercial printing. Most of the two-color machines add a plate cylinder and ink system on the basis of the single-color machine.
General office small monochrome offset presses do not have overprinting function, but in order to adapt to the development trend of higher and higher requirements for document printing quality and the increase of some multi-color documents and multi-color commercial prints, some office small offset presses Bridges and pull gauges have been added to the cardboard to become single-color or two-color offset presses that can be overprinted.
