To make an image sharper or less sharp
Unsharp masking (USM) adds visual sharpness to an image by increasing the contrast at the
edges of details in the image. ColorQuartet lets you apply USM automatically or semi-automati-
cally.
For general information about unsharp masking – see page 190.
Sharpening images automatically
EITHER: activate Sharpening in the Auto Functions section of the Magic Touch window.
OR: Set Unsharp Masking in the top section of the Scan Setup window to one of the Auto settings.
Sharpening an image by using a stored USM profile
Choose an existing desired profile from the Unsharp Masking menu in the top section of the
Scan Setup window.
Sharpening an image manually / Getting feedback on the USM setting
The USM parameters can be manually customized, but this is not usually necessary. Use this
option only if you are not satisfied with the results of the automatic USM function.
1 • First apply automatic USM to the image as explained above.
2 • Choose Custom... from the Unsharp Masking menu in the top section of the Scan Setup win-
dow to open the Unsharp Masking window.
3 • You can now view the settings made automatically by ColorQuartet, change them, and/or
save the new settings for future use. You can also interactively view the image with and
without sharpening, in a special split-screen feedback field.
• As long as one of these funtions is activated, ColorQuartet will intelligently
calculate an appropriate USM setting for each individual scan.
• Using automatic Sharpening in Magic Touch corresponds to using Normal
(Auto) in Scan Setup.
• For less sharpening, use Light (Auto) .
• For more sharpening, use Heavy (Auto) .
• For no sharpening, deactivate Sharpening in Magic Touch or set Unsharp
Masking in the Scan Setup window to None.
The menu lists any profiles that you have created and saved as
explained below under “Sharpening an image manually.”
