It seems that there is some confusion here between Pixels Per Inch (PPI) and Dots Per Inch (DPI) Photos from digital cameras use PPI while printers use DPI. The general rule of thumb is to use a resolution of PPI that's twice that of DPI. So, if they are using a 300 DPI screening for printing the cover, you need to have a 600PPI image that MATCHES their physical measurements. So, if the cover is 12.5X9, you have to have an image that is the same dimensions (12.5X9 inches) at 600 PPI. The rest, as someone said earlier, is the weight of the paper (Which incidentally, is literally how many pounds a standard ream of that paper weighs...) and the amount of sheen they finish the cover with. Good luck with this and congrats to you for getting a cover shot. Hope all of you have a very Merry Christmas/Holiday season.

Hello James, They are asking for 300 dpi, digital. I wasn't sure about the, "110 minimum /133 maximum line >>>screen, 80# cover, 45# gloss," which is apparently for the printer only. Marilyn
