with placed ArtPro files and PDF files coming from ArtPro or the ArtPro Action List Editor. Placed
PDF files from other applications work fine, as long as they do not define their own dot gain curve
inside the PDF, as the embedded curve has priority. If a placed PDF file coming from ArtPro or the
ArtPro Action List Editor already contains a dot gain curve, a warning is generated on PDF Output.
Always Generate CMYK Separations
This option includes all CMYK separations to deviceN color spaces as soon as one of the CMYK
separations is used. This option is only useful for customers that use a GMG color manager on
their PDF files.
Flattener
The Flattener is used to translate transparencies and blends. This is necessary when outputting
PDF 1.3 compliant.
The Flattener section, contains all settings to flatten Blend modes and overprints. It can also be run
as a separate action: Flatten Transparencies. The Flattener replace all blend modes by “normal”
objects, maintaining the final result, that is, the blend is calculated to whatever is underneath at
that time, and is adapted in a lineart object (if possible) or an image.
Image Settings
Use Image Downsampling At
All images with a resolution higher that this value, is resampled. This allows you to create smaller
PDF files, example: for a quick soft proof.
For Images Having at Least
If this option is on, only images with a resolution higher than the entered resolution, is downsampled
to the down-sample resolution. In the example above, when switching on the option, images with
a resolution below 450 ppi remain unmodified, while images with a resolution above 450 ppi are
downsampled to 300 ppi.
Use Averaging When Downsampling
This option is the same as in the more print settings. When it is activated, image quality is better,
but the output is slower. The difference with PostScript output is that CCITT images are averaged
too when outputting to PDF.
Image Compression
No Compression, Lossless compression (Flate), Maximum Quality, High Quality, Medium Quality
or High Compression. None means that all compression is taken off. Compressed images are
decompressed in the PDF file. A lossless compression means that the file will still be complete after
decompression. There is no loss of quality. In the three other cases, the files are compressed with
a JPEG compression. A higher compression means smaller files, but worse quality and vice versa.
Include RGB preview of images
This adds a lowres 72ppi preview of the large images inside the PDF. These previews are used by
some Acrobat plug-ins, to speed up previewing files.
Image Clipping
The Image Clipping option allows to force clip images to the smallest size inside the clipping path.
Allows calculation to include the full picture if clipping does not give any benefit, that is, if the sum
of the image parts is close to or bigger than the size of the full image. A full image is only included
once in the PDF file, even if it is placed multiple times.
Links
This option allows to include OPI comments into the PDF file. Choose between None (no links), OPI
links or Esko links. The option Embed Images allows to define if images with OPI comments should
be embedded as well. OPI comments can not be used in, for example, Illustrator, unless the InPDF
plug-in is used. For more information, see the InPDF documentation.
