Hurray, I just received my new proof prints.
So far they are looking great, so sale might possibly be starting this weekend!
The top book is from the previous batch of proof prints, see that grey-ish line? That's a little bit of the image on the back that managed to bleed onto the spine, also having the name and title turned this way looks a lot better, initiative of the designer, and a good call!
I'm happy with the result, now to make sure I didn't make the same stupid mistake as I did the first time, I have to check it's content as well. If all is as it should be, we are good to go live!
