REGISTER MARK READING METHOD

摘要

A head (30) of a cutting plotter is rapidly moved to a position above or near a portion where a register mark is printed on a medium (50) mounted on a platen (20) relatively in a X-Y direction above the medium (50) without taking a waste time by effectively using data on the position of the register mark stored in data storage means (80) for register mark printing. Then the head (30) is moved slowly above the medium (50) relatively in a X-Y direction to reliably read the register mark printed on the medium (50) by means of an optical read sensor mounted on the head (30) without failing to read it. Thus, the time required to read the position of the register mark printed on the medium (50) can be greatly reduced.
