5.2 Image Quality Adjustment 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.
