In more detail, when the printing paper passes through a specific drum, the printing paper can be printed in multiple colors at the same time as printing a plurality of printing surfaces on both sides of the drum. By passing through the printing apparatus in order to be able to perform a multi-color printing.

Typically, the rotary press is used to print on printing paper while rotating the hydraulic drum and the printing drum, and the multi-color rotary press installs the hydraulic drum and the printing drum in multiple stages so that the printing paper sequentially presses each hydraulic drum and the printing drum. It is designed to perform color printing while passing through.

The printing press performs printing by attaching a printing plate to the outer circumferential surface of the printing drum, and the printing standard is limited according to the size of the printing drum and the printing plate is attached to one printing drum to print. At that time, printing was performed by alternately attaching and detaching each printing plate to the printing drum.

Such a rotary press must replace the printing plate every time the printing state is changed. In other words, when printing calendars, there is a troublesome problem of printing while replacing or removing 12 printing plates from January to December, and workability is not smooth due to waste of time and manpower when replacing printing plates every time. there was.
