Specifying the reference image quality
To stabilize the image quality of this machine, specify the reference values (targets) of the entire printing system in
advance.
If you change the setting value in [Custom Screen], hue variations may be drastically changed. If you change the
screen, specify the standard image quality following the procedure to avoid hue variations.
Tips
If the image quality has not been appropriately adjusted only through daily calibration, you may improve the situation
by carrying out the following tasks.
Carry out the adjustment continuously in sequence. If you have interrupted the adjustment, select "Step 2. Gamma
Automatic Adj." each time before restarting calibration. For example, if the adjustment is interrupted at the end of "Step
3. Density Balance Adjustment", execute "Step 2. Gamma Automatic Adj." at the time of restart, then execute "Step
4. Calibration (without
Relay Unit RU-509
)" or "Step 4. Color Density Control (with
Relay Unit RU-509
installed)" in
sequence.
If sufficient adjustment results are not obtained via daily maintenance, also carry out the adjustment in this order.
For details about the setting procedure, refer to the
HTML User's Guide
