Image Sharpening
Note:
Sharpening factor for all images
This parameter defines the base sharpening applied to all images in a
document – including those that were scaled down.
Although there is no maximum limit for this value, only values of up to
approximately 2.0 are likely to produce acceptable results. Enter 0 to disable
this type of sharpening.
Images that were scaled down may be sharpened by a higher degree,
depending on how the FACTOR FOR SCALED IMAGES ONLY has been set.
Factor for scaled images only
This factor controls the intensity of sharpening automatically applied to
images scaled down to less than 95%.
The intensity of sharpening increases automatically with higher scaling
factors. Images reduced to a smaller size will be sharpened more than
images that have been scaled less. The degree of sharpening is calculated
automatically from the scaling factor of an image and multiplied
with the factor specified here.
The greater the FACTOR FOR SCALED IMAGES ONLY, the higher the level of
sharpening applied to images scaled down by the same degree (see
Fig. 3-13). Usually the default of 1.0 provides the best results. With this
setting the sharpness of a scaled image visually corresponds to that of
the original image. Enter 0 to disable this type of sharpening.
There is no maximum limit for this factor, but internally the sharpening
value calculated from this factor is limited to 3.5.
