Increase Clarity of WMS

[Kyle Mulka]

I have these very detailed floor plans that I'd like to georeference and 
display through mapserver's WMS sever, however, the clarity of the 
images degrades when it goes through. How can I increase the clarity of 
these floorplans through the WMS?

Here's with mapserver:

Here's without (simply chopping up tiles using Imagemagick)

Here's the parts of the map file for just the first floor:
MAP

   FONTSET fontset.txt
   PROJECTION
       "init=epsg:4326"
   END
IMAGETYPE png24

   TYPE raster

       "wms_srs" "EPSG:4326"
   END
   STATUS ON
END
END
