the machine to make fine adjustment as shown above picture (None stop register device)
To save material, the plate cylinder for each color should be installed on approximately
the same position of the corresponding group. If this is done correctly, the position of the
picture to be printed for each color will be very near the register position, which can
minimize the times of register adjustment necessary for the setting and reduce the waste of
the material to be printed. It is recommended that marks be made on the same position of
each plate cylinder or gear, so that the picture on the printing plate adjusted according to
the marks will be very near to the register. When each cylinder is installed on to the printer,
the marks can be used for accurate installation (the accuracy is within a gear). The mark on
the paper belt should be calibrated with the mark on the cylinder and gear of the first group,
and then inch start to move the paper belt to the next color and calibrate with the mark on
the next cylinder. This method can be used for rough peripheral calibration so as to reduce
the waste of trademark belt and the time for setting.
