Problem/Question
You wish to overlay two images but the Overlay button is grayed out.
Probably you're using a PrintEnvironment containing spot colors. The combination of spot channels and overlay can lead to faulty prints. This is why the function is disabled by default in such cases.
Solution/Work-Around
Not recommended, and on the user's own responsibility, there are two ways to enable overprinting.
- Press the Alt key while moving one image over another.
- Application Defaults > User Preferences > Job > activate Always allow Overlay Mode.
