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 then add the TIFF file containing the desired spot color channels into an OPI search path location in the Prinergy software.
- Using the Channels palette in Photoshop, create the images as TIFF files.
- 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.
- In the Image Attributes area, select the Include Spot Colors in Photoshop TIFFs check box.
- In the Spot Color Handling section of the refine process template, select the Lookup Recipe in Color Database check box to provide an accurate color definition for proper color matching and trapping. You need to look up the recipe because Photoshop includes only the name of the spot color channel, not the color definition.
The Prinergy software merges the CMYK color channels with all spot color channels to produce a single, multi-channel (DeviceN) image.
