Exporting Layouts
‘Images’ Tab
• If this option is enabled, the image resolution will be reduced to the
output RESOLUTION specified on the PAGE tab (see page 3-31). This
may reduce file size, but the images have to be resampled.
Note that the resolution is not increased if it is lower than the output
resolution. Use the ADJUST IMAGES TO OUTPUT RESOLUTION parameter
for this purpose.
Note:
Resampling an image usually results in a loss of quality. This can be
compensated by means of interpolation and sharpening (see below).
When positioning an image in ORIS PDF Tuner, you can automatically
set the image resolution to the expected output resolution. For more
details refer to Scaling Images to Original Size (page 19-9).
PDF, EPS,
PS only
Note:
Adjust images to output resolution
Enable this option to set the resolution of all images to the output RESO-
LUTION specified on the PAGE tab.
This option is similar to the REDUCE IMAGE RESOLUTION option, but also
allows the image resolution to be increased if it is lower than the output
resolution. Note that this also increases the size of the output documents
and reduces image quality.
Interpolate images
Use interpolation to improve the quality of images that are resampled to
a different resolution. Select the interpolation method to be used:
• NO – No interpolation, lowest image quality. There may be artefacts
such as jagged edges (stairstepping) or missing lines.
• LINEAR – Better image quality, but conversion times are longer.
• CUBIC – Best image quality, but considerably longer conversion
times (up to 16 times longer than with linear interpolation).
When creating PDF, EPS or PS documents, this parameter is only available
if the REDUCE IMAGE RESOLUTION or ADJUST IMAGES TO OUTPUT RES-
OLUTION option is enabled.
