Saturday I got the proof copies of the Zombie Mall rules that I made through CreateSpace. One of the reasons you order proofs is to check the lightness/darkness of images. I had always heard that you want to adjust when making graphics for printing, as looking at things on a (lit) monitor will make images lighter than they will appear in print.
On the back cover of my rule books, I've got a faded/semi-transparent image on the top for decoration/to take up what would otherwise be white space. I set the transparency to 35% when making it.
What I received is pretty close, but when actually printed out on a glossy cover it looks more like the printer was just running out of ink. Now I've gone back and changed the transparency to 75%, which should offest it enough from the pseudo-wrap-around picture that's on the front and back covers.
While I was at it, I noticed I entered the wrong web address on both back covers. My lesson there is to not go surfing to similar web addresses when typing things up!
I haven't committed the changes yet, as I think there are a couple of little things I might tweak. Change a little spacing here and there.
If I read everything right, these should be showing up on Amazon by the end of the week - unless my tweaking with the covers starts the process over.
