Selecting Image Resample Methods
Use Image Resample to select an interpolation method. This
option provides the you with the ability to select an interpolation, or
image resample, method in order to achieve maximum Image
Quality at the desired RIP performance. Interpolation is defined as
the process of estimating a value of a function between two known
values. In the Image Interpolation context, the function of known
values is the input image, and the estimated values are the values
calculated for the output image. 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: The printer determines the image
scaling of the given job. A job entering the queue that does
not contain a value, is assigned the Default value.

Bi-Linear: 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.

Nearest Neighbor: 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.
