Adjusting Image Quality
The Xerox Nuvera user interface contains a set of Image Quality adjustment tools for
Copy, Scan to File
and
jobs. Using these
controls, you can make adjustments to images containing text, photographic images, halftoned images, as well as documents with
mixed image types. This is useful if the original document is less than perfect; i.e., text/images are too light or too dark.
To learn more about these capabilities, explore the links at the left.
To adjust image quality on copy and scanned jobs
To adjust image quality on print jobs
1. At the Xerox Nuvera user interface, click on
Copy
(or
Scan to File
), then click on the
Image Quality
tab.
2. Choose the
Original Type
of the image to be copied. Click on the
Original Type
button, then click on the
Rendering
Options Setup
button. Choose any options according to the condition and type of the original document.
3. Click on the
Basic
tab, then use the
Darken/Lighten
control to make small corrective adjustments.
4. Click on the
Image Quality
tab, then click on the
Image Adjustments
button. Use the
Contrast, Sharpness
and
Background Suppression
controls to make small corrective adjustments.
5. Set
Print Quality
. The Toner Saver selection uses less toner and is more economical than the full quality setting of Normal. It
is useful for scatter removal without causing a light solid image on the page. You may want to use the Normal setting when
printing proof documents.
1. Select
Print From File
on the Service menu and use the Files tab to locate and select the job.
2. Select the
Image Quality
tab.
3. From the
Mode
pull-down menu, select the printer emulation setting. The DocuTech 135 setting prints output that is similar in
appearance to that of the DT135 printer.
4. Use the
Print Darkness
control to make small corrective adjustments in increasing or decreasing darkness. All pixels in the
image are moved either towards black or white. The values closest to 0 are intended for small adjustments to the darkness of
text and pictures. The da/-3 settings will make a noticeable difference on text but not recommended for most pictorials.
5. Select a
Resolution
. Since resolutions vary from printer to printer, use this option to achieve better performance for jobs that
were saved at 300 dpi.
6. Set
Print Quality
. The Toner Saver selection uses less toner and is more economical than the full quality setting of Normal. It
is useful for scatter removal without causing a light solid image on the page. You may want to use the Normal setting when
printing proof documents.
7. To select a halftone, open the job. From either the Print Properties window or the Job Properties window, select a
Halftone.
This allows you to adjust the pattern of dots or lines of varying sizes applied to an image of varying tones, or same sized dots
applied to a tint of color.
Stroke Thickening (increasing the weight or width of a character)
1. Open the
Job Manager
and select and open the job.
2. Select the
Image Quality
tab.
3. From the Job Properties window and the
Stroke Thickening
field, adjust this setting to control the thickness of fine lines
created by the PostScript stroke command.

NOTE
: The Copy and Scan functionality is only available if your system includes the integrated Document Scanner module. If
the Enhanced Line Screen license is enabled, the system supports jobs with 85, 106, 125, 134 and 156 lpi halftone screens. If
this license is not enabled, only 125 lpi is supported.
TIP
: If you copy/scan a great number of the same type of original documents, you can set custom image quality defaults. For
example, if the majority of your copying/scanning is of dark photographic content, the system defaults can be set to
accommodate this, saving you job programming time. To set up your system defaults to match your original input, contact your
System Administrator.
NOTE
: If the Enhanced Line Screen license is not enabled, the Halftone selection is not available since there is only one
halftone (125 lpi) offered.
