Rich Black Printing

If user tends to combine other colors to create black instead of using 100% black alone, overexposure of the image may occur.
In addition, if a bright color image is placed in the middle of dark color, inks collation may occur and results in poor quality printing (see image below).

Tip. If user wish to create design with high density black, it is recommended to add 20% Cyan into 100% Black, however, this does not apply to small letters and fine lines.
