Image interpolation attempts to produce a smooth transition
between adjacent samples rather than simply replicating pixels
(which would result in “blocky” images).
The interpolation methods that may be selected (in addition to the
system specified setting) include:
•
System Specified: Use this default method if you are unsure
which of the other methods to use.
•
Nearest Neighbor Interpolation: A method used to scale
image data (pixels) from one resolution to another. The output
pixel value is simply the value of the input pixel closest to the
output location. Nearest neighbor interpolation is the highest
speed interpolation on DocuSP.
•
Bi-Linear Interpolation: A method used to scale image data
(pixels) from one resolution to another. The replacement pixel
in the scaled image is calculated using a weighted sum of the
four nearest pixel values in the source image. This method
offers higher quality than Nearest Neighbor Interpolation.
•
Smart Interpolation: A method used to scale image data
(pixels) from one resolution to another. This interpolation
method automatically chooses between bi-linear interpolation
and filtered interpolation based on the input image
characteristics. Smart interpolation is the highest quality
interpolation available on DocuSP.
To select an interpolation method, perform the following steps:
1. Open Job Manager.
2. Double-click a job in the Active or Inactive Jobs list. You can
access Completed jobs if Retain PDL Files is enabled. For
additional information about Retain PDL Files see Setting the
Job Policy.
3. Select the Image Quality tab.
4. Select the Image Resample FAB.
5. Select the radio button next to the Interpolation method you
wish to employ.
6. Select [OK] to commit changes and exit the job properties
tabset, or select [Apply] to save current changes and continue
making changes.
