created with Adobe Photoshop 5 or later. Duotones from older
versions of Photoshop are extracted as CMYK images when im-
ported, so these should be placed instead.
DCS: A DCS image is in fact a preseparated EPS. So the same
rules apply. Importing will make it a TIFF, which allows us to map,
preview, trap,...But a DCS cannot be imported directly (e.g.
dropped in a hot folder to be imported), it has to be used in a PS
or PDF file. In other words, if the DCS image is placed in a (Illus-
trator, XPress,...) document that is saved out as a PS or PDF it
can be imported and mapped correctly.
OPI images (Open Prepress Interface): When OPI low resolution
EPS sample images are used in a document that needs to be im-
ported in Nexus, the images always have to be placed, if they are
not automatically replaced by their high resolution version upon
import (see the OPI section). If they would be imported, Nexus
would create complete new (low resolution) TIFF images that will
not be recognized and replaced by the OPI server, resulting in a
low resolution output. If low resolution TIFF images are used, they
can typically (for most OPI servers) mapped and further worked
with (e.g. for trapping).
There are three ways to put an image in a PS or PDF file.
•‘OPI’: The image is omitted (TIFF, EPS, DCS,...). This means
the original picture is not included in the PS file, only the link is
available. The link is a path, indicating the place where the im-
age can be found on the hard disk, or anywhere else in the net-
work (e.g. on the file server). These PS/PDF files are obviously
very small. They are quick to write and copy.
In the links dialog of PS/PDF Import, they will respond to the
settings under Omit. In the picture list, under display links,
these images will have ‘OPI:’ in front of the name.
•‘EPS’: The image is embedded. The complete original picture
as well as the link is included in the PS file. This means in ArtPro
we can choose which we will use. These are usually EPS’. They
will respond to the settings under Embed. These images can
be recognized in the picture list, by the ‘EPS:’ in front of the
name. Obviously these PS/PDF files will be larger than in the
•The image can be completely embedded without the link. This
is usually with TIFF images. (Freehand is an exception. All TIFFs
are always embedded in the PS files, with the link)
Because no link or name is available, ArtPro can not display
these images in the picture list. No link settings can be defined.
These images are extracted to TIFFs on disk during import.
