what format are you saving it in ?
8.5 " x 11" = 93.5 sq inches
200 x 200 dots = 40,000 dots per sq inch
3.7 million 'dots' each 'dot' is 24 bits (3 x 8 bit colours)
= 89.8 bits = 11 Megs per page x 4 pages = 44 Megs
some how i'm a bit over ... don't have my glasses with me
try dropping the number of bits per colour.
the two tools i use are ImageMagick and xv
imagemagick is not for the light at heart :)
you should see the file size's for just one strip of a billboard !!
