5-43Reference: The Settings Window

Unit Selection

The unit of measurement for resolution is in dpi (dots per

inch) or lpi (lines per inch). Lpi settings are dimmed if the

ruler unit is in pixels.

To select your option:

• Choose dpi if you know precisely the resolution you need

for your image. For more details on resolution, see the

Basic Concepts chapter.

• Choose lpi Draft to produce resolution that is one times

the screen frequency. Draft quality may result in output

images that look a little blurred or indistinct at edges.

• Choose lpi Medium to produce resolution that is one and

one-half times the screen frequency.

• Choose lpi Final to produce resolution that is two times

the screen frequency.
