separation files. DCS files can be single-file or multi-file. When
processed through the normalize function, they become PDF files
(separated) that cannot be color matched or trapped. For information
about creating composite output, see the
Re-combine
check box in the
refine process template.
An alternative workflow is to place partial-page raster DCS files in page
layout software, such as QuarkXPress or Adobe PageMaker, and save
the files as composite thin PostScript. You can then add the PostScript
file to a Prinergy job. When Prinergy fattens the file, it creates a
composite DCS file.
About duotones
If you create duotones with Adobe Photoshop 3.0 or 4.0 or any version
of Corel PhotoPaint, you must save the duotones as separated DCS
files. Saving as composite PostScript (EPS) will not preserve spot
colors (that is, the image will be converted to process colors).
If you create duotones in Adobe Photoshop 5.0, you must save them
using Adobe Photoshop 5.0.2. Photoshop 5.0 prevents duotones from
working correctly on PostScript 3 devices. The free upgrade to
Photoshop 5.0.2 is available for download from
/.
Saving duotones in Photoshop software
To save duotones in Photoshop, select
Image
>
Mode
>
Multichannel
.
Then, save the file as DCS singles. Ensure that the image is not set to
CMYK
mode in Photoshop software. If the image is set to CMYK
mode, spot colors are converted to process colors in Prinergy.
Saving duotones in layout software
You can output duotones (that were created in Adobe Photoshop 5.0.2
and saved as DCS files) from layout software as one of the following
formats:
●
Composite PostScript with OPI comments (composite thin
PostScript). When Prinergy fattens the file, it creates a composite
file.
●
Separated PostScript with images (separated fat PostScript).
Prinergy cannot perform trapping and color-handling functions on
separated input files.
