I love the idea, although I'm sure my scanner is probably not the best and my upload would be rejected. May I try just the same and see if this is the case? If it gets reworked, would the person that fixed it at least show us what was done to make it better? I would love to learn anything in the process if possible.

Chewy is correct in one thing though, not to say that is her case, just that many scanners are not capable of producing a quality scan, this is due in large part to the "optical resolution" limitations of the hardware, no matter what software you use "physical" limitations cannot be over come.

Many cheaper printer/scanner combos fall in this category due to them adding the cheapest scanning hardware they could find to the print device, just so they can sell it for a little more profit.

To do really high quality scans you have to have a good scanner with good optical resolution.

They fool consumers by printing in big bold on the box huge numbers like 9600dpi "scanning" resolution, yet when you read the actual specs -the real "optical resolution" is only 1200 dpi or less and the "extra" is guesstimated by the software driver and that my friends just never works out.

To do decent scans a scanner must have at minimum 2400dpi Optical Resolution, just saying...

Here is a quick example, the one on the right can never be "made" good with no amount of work or Photoshop expertise - yet the one on the left will need little to no work other than fitting and aligning it to a template for size.

Thanks for the experience! It was fun and educational... :)

I have just a quick question after all of this (it could have been a lot more lol). When you mention "All scans MUST be at 1200 dpi minimum initially then reduced to 600 dpi for upload." How is this accomplished? Is it simply to scan the cover at 12000 dpi and once saved, then crop (resize) it at 50%?

Yes, it's best to scan at the upper optical limit of the scanner then reduce it's size down to 600dpi for processing then the final step is to reduce it to 300dpi before it is uploaded.
