A while back I wrote a two-part article (Part 1, Part 2) about a recommended workflow for publishing with MagCloud which has received favorable feedback from both MagCloud and other readers. In those posts I mentioned that MagCloud used two different profiles for saddle-stitched and perfect-bound magazines and suggested that I would most likely stick with the perfect-bound option. I have been recently informed that MagCloud now uses a unified profile for both binding options which should make life a lot easier for all the publishers using their services.
The new soft-proofing profile is available for download (no longer available, contact MagCloud). After downloading it, you should go back to the original articles and replace the references to the profiles with this one. The earlier articles did not include links to any profile but MagCloud had allowed me to share them with anyone who wanted to use them. This should make the series of articles on this subject more complete and useful.
