RYOBI RP 740-425 Auto


The RYOBI RP740-425AUTO high-precision CCD camera detects plate register marks exposed during plate making. It then measures the plate's overall image skew, and after its internal motors correct plate positioning laterally, vertically and diagonally, it finally punches the plate.


Punching requires no special skill and drastic reduction of plate register adjustment work on the press shortens make-ready time and realize high quality printing with low cost. The plate punching which used to be done before plate making can now be done automatically and precisely after plate making by using image detection technology. This was highly evaluated in the examination. Furthermore, as it only takes about 30 seconds to punch one plate, four separations can be completed in as little as two minutes.

Furthermore, it was designed to match the color and design of the pre-press equipments. And, the simple design placing the wiring and positioning the panel display inside the cover enables operators to operate it safely. Symbols which are understood worldwide were adopted for the indication on the color display. All these were also highly evaluated.
