Exporting duotone images to other applications
To export a duotone image to a page-layout application, you must first save the image in EPS or PDF format.
(However, if the image contains spot channels, convert it to Multichannel mode and save it in DCS 2.0 format.)
Remember to name custom colors using the appropriate suffix so that the importing application can recognize them.
Otherwise, the application may not print the colors correctly, or it may not print the image at all.
