FX-Viewer showing an empty room environment
16/10/23 15:24 Filed in: FX-Viewer
If after installing FX-Viewer and Ghostscript you are getting an empty room after dragging a Color-Logic PDF into FX-Viewer:
1. First of all make sure your PDF has a Color-Logic separation – if the PDF does not contain the "CL 4713 SILVER" spot color it will not be able to do the rendering.
2. If your PDF does contain the Color-Logic spot color, it could be a problem related to the version of Ghostscript that is installed. We would recommend using v9.55 from our Ghostscript download page – Just download, run the installer to update to the latest version. An empty room environment is usually related to the version of Ghostscript and the Mac OS.
