Specifying The Reference Image Quality (Image Controller Ic-417/Image Controller Ic-313) - Konica Minolta AccurioPress C2070 Quick Manual

6.2 Image Quality Adjustment
6.2.7 Specifying the reference image quality (Image Controller IC-417/Image Con-
troller IC-313)
To stabilize the image quality of this machine, specify the reference values (targets) of the entire printing sys-
tem 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.
Order
STEP1
STEP2
STEP3
STEP4
STEP5
STEP6
Carry out the adjustment continuously in sequence. If you have interrupted the adjustment during processing,
execute "STEP2. Gamma Automatic Adj." before restarting the adjustment. For example, if you have inter-
rupted the adjustment at the end of "STEP3. Density Balance Adjustment (with the Relay Unit RU-509 in-
stalled)", execute "STEP2. Gamma Automatic Adj." when restarting the adjustment, then execute "STEP4.
Color Density Control".
If sufficient adjustment results are not obtained via daily maintenance, also carry out the adjustment in this
order.
