the calibration chart. If there are no lines that overlap completely, you can also
estimate the decimal number according to the relationship between the best-overlap
line group and the side line group. Click on "Standard" and pop up the dialog box. Fill
in the read data into the "Measure Value" and then "Apply".
Print Stand Step Calibration Chart again and observe whether it is aligned at the
zero-scale position. If aligned, it has been calibrated. After standard step is
calibrated, check the accuracy of other Pass steps in turn. If not, each Pass needs to
be calibrated independently with the above methods.

X-direction calibration of Print-head
In order to make the printing contents of each print-head cover together, it is
necessary to adjust the color offset value of each print-head. The offset value is often
different in different printing directions and different head carriage moving speeds.
Calibrate low, normal and high speeds separately, and the two directions need to be
calibrated separately.
Read out the corresponding direction offset value of the print-head from the
correction unit in the printout. The method of reading is to find out the value of the
line or color that best coincides reference color with the horizontal direction of the
calibrated color.
