HP 510 - Manual (Page 164)

Improving line quality and graphics details
The Set-up menu Optimize for option allows you to select the correct mode for the type of job you are printing.
Two modes are provided: Line drawings/text and Images.
Selecting the Line drawings/text option smooths the fine graduations along the angles and curves of the printed
image to refine overall print quality. This enhancement produces:
•
Crisper lines
• Finer detail
• Line drawings with a ‘sharp’ appearance
The Line drawings/text option affects only prints that have color content.
Selecting Line drawings/text (the default setting) ensures you will always get the best quality color prints, except
when printing the following files:
•
Mixed lines and scanned color images
• Mixed lines and color photographs
For these files it is recommended that you select Optimize for > Images.
