We have been in communication with the printer of the Thundercats omnibus volumes, and they are working hard to prep the prototypes of the print run.  For the standard softcover volumes, we are using very straightforward printing processes that everyone is used to.  For the oversized hardcover, we always like to have a prototype sample because we want to ensure the quality is unrivaled.  We would also like to know exactly what the materials will look like when they are put together in the final configuration.  Every facet of printing is detailed before they begin (all the materials, finishes, paper types, printing, and binding processes).  

The really great news here for backers is that we are printing in North America.  It's a more expensive process, but it means a faster turnaround time from when they start running the books on press.  Once we have press time reserved and they begin the printing, we will have a solid timeline +/-a week or two at most.

We're talking with the printer weekly about the process.  So we will try to provide regular updates as we advance, even if the update is that things are still being finalized for printing to begin.  Keep an eye out for the next check-in coming soon.
