Abstract
A method of printing a document using a fluid-ejection printing device includes receiving gray scale image data for the document, and identifying at least one area fill feature of the image data. It is determined whether the at least one area fill feature will be printed with a combination of different black inks and is likely to produce a visible image defect if printed in an N-pass bidirectional print mode, where N is an integer. Non-fill regions of the image data are printed using the N-pass bidirectional print mode. The method further includes automatically switching to an M-pass bidirectional print mode for printing the at least one area fill feature when it is determined that the at least one area fill feature will be printed with a combination of different black inks and is likely to produce a visible image defect, where M is an integer greater than N.
