How Platemaking and Printing is Performed
The machine performs two processes: platemaking and printing.
Platemaking
In the “platemaking” process, the old master on the drum is removed while the thermal head creates the
scanned image on the new master and transfers it onto the drum.
Printing
In the “printing” process, paper separated from the stack by the feeder roller and paper separator unit is
pressed against the drum unit by the press roller. There are small holes over only the image area of the master
that is attached to the drum, and ink that seeps from these holes is transferred to the paper. The paper is then
peeled from the master by the paper stripper finger. The paper is directed onto the paper ejection belt by a fan
unit and discharged from the machine.
