Setting the Quality factor

What it is

The Quality Factor determines the number of electronic samples taken for each line of the

screen ruling. It is typically set to between 1.4 and (max) 2.0. ColorQuartet remembers the last

value you entered and uses it as a default until you change it.

• A higher Quality Factor means that the scan contains more information. The printed image

will be better, but the file size and scanning time will increase.

• Using a high Quality Factor is not meaningful if the output device and/or printing process is

not able to reproduce all the information contained in the scan. If you’re not sure how high to

set the Quality Factor, make test scans of the same image at (for example) Q = 1.4, 1.6, 1.8 and

2.0 and evaluate the results after printing.

How to set it

In the Size & Resolution section of the Magic Touch window or the Enlargement & Ruling or Res

section of the Scan Setup

window, type in the desired Quality Factor and press the tab key to con-

firm.

NOTE: Since the

Scan Resolution is based on Enlargement x Screen Rul-

ing x Quality Factor, changing the Quality Factorwill also automatically

change the Scan Resolution. This keeps the Screen Ruling and Enlarge-

ment at the desired settings.
