That's true generally.  Anything other than actual photographs (continuous tone 
images) should NOT be run through JPEG because JPEG is not intended for, and 
unfit for, anything else.  Printouts, line drawings, and anything else with 
crisp edges between dark and light will be messed up by JPEG.  PNG and TIFF are 
examples of appropriate compression schemes.
