Doc, it hurts my right eye when I drink my coffee with the spoon in the cup.

Don't use JPEG at all for diagrams. Use a vector format. And only if you
can't use a vector format, then fall back on a high-resolution PNG. In any
case when discussing the output quality of PS or PDF, print the document
first. If it looks good on printer but not on screen, blame the PDF
rendering software. (you won't avoid all on-screen scaling artifacts as 
long as you embed bitmaps anyway).
