Hi,
I don't seem to be able to reproduce this. I get
the same numbers as 1.6.3 for releases back to 1.5.0 and before,
given the same .ti1 file - ie. nothing seems to have changed
with printtarg.
Note that the effect of targen -p has been made more uniform (it wasn't
being applied very consistently), so you will get slightly different .ti1
files out of 1.6.2 and 1.6.3, so maybe this is what is changing
the contrast numbers.
