The printer just checked back in with us about the corrections that were needed on the print file.  The first pass consisted of a few dozen minor problems with the files that we worked to get fixed.  Now the second file pass has come back and we are down to just 8 problems which are being adjusted to meet the specifications of the printing process.  Our production team is working on getting those changes made and uploaded to the printer for another pre-press pass review.  We expect to hear back on that shortly.

The printer is also working on the prep to have the different cover editions printed.  We received a few notes on the covers where certain details and bleeds need to be revised.  We're working on those changes right now alongside the interior adjustments to get us to a point where the covers and interiors are ready for press.  Based on our progress we're expecting these issues to be resolved in the same timeline.  

We are also waiting for photography of the metal slipcase prototypes.  We know the printing process for these real metal slipcases is complicated but the printer is keeping us updated on their progress with the factory and the prototypes.  

As soon as more information is available we will post it up to keep you in the loop on the progress.  At the completion of the print ready process we should have the timeline for the manufacturing of the books to share.
