channels, so after a single color is intercepted, you need to print an ink test diagram to see
the ink volume of other channels.
2.Generally 2color channel need not intercept ink.
3.3color channel will intercept ink according to 4color channel. To ensure that the colors are
richer, try to reduce the interception. But ensure that a certain transition of colors is achieved
from 3color channel to 4color channel. It’s suggested to get the value of 3color channel by
the value of 4color channel minus 40.
1.The 4color channel is the key to control the ink deposit. To ensure richer colors, try to
reduce the interception while ensuring that there is no ink deposit.
2.The single-color ink volume can be adjusted as needed. 2color ink generally needs not be
intercepted. 3color ink should intercepted less, and 4color should be intercepted as needed to
ensure that there is no accumulation or deposit of ink.
3.The ink interception mainly depends on the ink volume of single color and 4color and the
color cast of 3color mixed ink.
Interception Experience Value of Color Curve
1.If the printed image is black, properly reduce the ink output below single black 50%, and
the CMY 3color 50% can also be reduced properly.
2.If the figure image printed is yellowish, properly reduce the yellow ink volume by below
40%.
3.If the image printed is grayish as a whole, properly increase the black ink output by above
60%.
4.If the image printed is not saturated enough, properly increase the CMY 3color ink output
by above 60%.
5.Do not adjust too many points at a time or make a significant adjustment if you are not
certain.
7.5 Linear Calibration
Print a calibration diagram. After the image gets dry, cut the calibration diagram. If the
instrument calibration fails, click the button “Calibration Device”. After it’s calibrated by the
device, scan the color blocks.
