Accurate graphic size calibration
CTP with external drum has many advantages. However, multichannel scanning may cause the parallelograms distortion in the graphics. Amsky's unique technology of graphic calibration enables graphics to present perfect rectangles and eliminates dimensional deviation caused by different thickness of plates.
The registration accuracy of one Amsky CTP is 5 microns. Between two CTPs, it can be within 15 microns after being calibrated.
