I assume then that you're not printing on inkjet or that you interpolate the 
file up before printing.. A 15 meg file would yield only about 90 dpi on 13 x 
19. Ideal dpi for most inkjet printers is around 300 dpi. If I print a 13 x19 
from a 15 meg file on my Epson 2200, I can count almost count dots.
