OK, got it.
All seems to be good.
DPI is 300 and cover dimensions are what I think PSV cover is (about 20 by 12 CM).
I can think few problem causes:
- You have fit to page option on. -> Turn it off.
- Scaling is not 100%. -> Set it to 100%
- The program you print from some how screws the DPI. -> Try other program. MS Paint should work fine.
Great looking cover by the way.
