I recently uploaded a book to Amazon with a cover carefully created with Latex.
I tried to make the cover as simple as possible so that whatever process Amazon was using would not interfere. I was horrified to see the effect pictured above.
You can see a clear "crinkling" effect that is an artifact of the image optimization process. Is this because certain colors are more susceptible to this? Should I have some kind of texture in the back to avoid this?
I had the same kind of problems with another cover, and I tried to correct them with this one. I don't know how to make my cover any simpler than white text on a maroon field.
Any advice would be appreciated.
