Compression
Use this parameter to compress the images used in the document, thus
reducing file size. The following methods are available:
• JPEG (lossy) – Use the QUALITY and FILE SIZE parameters to select
the JPEG compression level.
• JPEG2000 (lossy; for PDF only, not for PDF/X)
The temporary PostScript file will be created with LZW compression
(lossless) and then JPEG2000-compressed by Acrobat Distiller.
• LZW (lossless, not for PDF and PDF/X)
• ZIP (lossless, for PDF and PDF/X only)
Quality
Determine the JPEG image quality by either entering a number or selecting
a quality level from the list:
LOW 0–4
MIDDLE 5–7
HIGH 8–9
MAXIMUM 10–12
The lower the quality, the higher the compression level and the smaller
the file size.
File Size

Note:
Drag the slider to the left to increase the JPEG compression level. This
reduces file size at the expense of quality. Drag the slider to the right to
reduce the compression level. This increases image quality, but also file
size.
Sharpen images
The program is capable of automatically sharpening images. This option
allows you to switch the sharpening function on and off.
Use this function if your images lack sharpness, e.g. because they have
been scaled down. Images which are scaled down become blurred
owing to interpolation. This effect increases with higher scaling factors.
The intensity of sharpening can be controlled by two parameters: SHARP-
ENING FACTOR FOR ALL IMAGES and FACTOR FOR SCALED IMAGES ONLY.
If the sharpening values resulting from the two parameters differ for a
scaled image, the greater of the two values will be applied.
