Note
Halftones refer to color shades between the darkest color and the brightest color.
The printer replaces the color shades with a collection of small dots to express the halftones.
When you select Auto, the data is printed with the optimal halftoning method for the selected
print quality. Dither arranges the dots according to fixed rules to express the halftones.
Diffusion places the dots randomly to express the halftones.
4. Complete the setup
Click OK on the Main tab.
When you execute print, the image data is printed with the selected print quality level and halftoning
method.
Important
Certain quality levels and halftoning methods cannot be selected depending on the settings of
Media Type.
Note
If part of an object is not printed, selecting Diffusion for Halftoning may solve the problem.
