Including clipping paths during OPI
With OPI, you can use the spot color channels created in TIFF images.
Notes: If the images are not Photoshop TIFF files, Prinergy ignores clipping paths.
To use the spot color channels, you can use alternative methods. In software other
than InDesign, save the images as DCS files, and replace them in the original
layout. With InDesign, which does not omit TIFF files for OPI-containing spot
colors even when OPI is selected in the Print dialog box, do either of the following
actions:
●
Create a plain alternate CMYK image for use as a proxy. Print the PostScript
including the OPI comments but omitting the images. Add the TIFF file
containing the desired spot color channels to an image search path.
●
Use proxy images created by an OPI solution, such as ColorCentral or Asset
Library, for low-resolution image placement into InDesign. These images will
be replaced by their high-resolution counterparts during the OPI step of the
refine process.
1. Create the image as TIFF files in the Photoshop software.
2. In the
Image Replacement
area of the
Fonts and Images
section of
the refine process template, select the
Search for High-Resolution
Images in Image Search Paths
check box to enable OPI.
3. In the
Image Attributes
area, select the
Apply Clipping Path in
Photoshop TIFFs
check box.
4. Refine the files.
Including spot color channels during OPI
With Prinergy OPI, you can include the spot color information
contained in the channels of TIFF images.
Note: If the images are not Photoshop TIFF files, Prinergy ignores spot color
channels during OPI. Save the images as DCS files and replace them in the original
layout.
The InDesign software does not omit TIFF files for OPI-containing spot colors,
even when OPI is selected in the Print dialog box. Create a plain CMYK image as a
proxy, print the PostScript, including the OPI comments but omitting images, and
