Times font sizes are different on screen and on eps files

I have 4 different GUI window sizes (XL,L,M,S).
In addition the user is given the ability to swith between 1:1 and 16:9
canvas aspect ratio.
When the current canvas image includes a color_bar then its
marks/labels, which are powers of ten (for instance: 10^2, 10^3, ..,
10^-4) are all displayed using the Times font family but the font used
for the base (10) is on purpose slighly bigger than the font used for
the exponent.
The choice of the base and exponent font sizes vary with the GUI window
(XL,L,M,S).
In addition, both the base and the exponent font sizes get rescaled
proportionally upon switching between 1:1 and 16:9 aspect ratio.
The above works fine on the screen. But when the 16:9 view is saved to
an eps file then, especially in the M and S GUI windows, the exponents
are not readable, even if on the screen they are. In the printout they
look like shapless blobs.
A Tcl/Tk expert, namely Ralf Fassel, made me notice that the subset of
sizes available for the Times font family is platform dependent. For
example on heimdall, a Linux cluster that I use for development, I get
the following:
[mauede@heimdall dat]$ ./Wish
% for {set size 6} {$size <=64} {incr size} {
puts "Times $size is rendered [font actual [list Times $size] -size]"
}
Times 6 is rendered 7
Times 7 is rendered 7
Times 8 is rendered 7
Times 9 is rendered 9
Times 10 is rendered 10
Times 11 is rendered 10
Times 12 is rendered 12
Times 13 is rendered 12
Times 14 is rendered 14
Times 15 is rendered 15
Times 16 is rendered 15
Times 17 is rendered 17
Times 18 is rendered 17
Times 19 is rendered 17
Times 20 is rendered 20
Times 21 is rendered 21
Times 22 is rendered 21
Times 23 is rendered 21
Times 24 is rendered 21
Times 25 is rendered 21
Times 26 is rendered 21
Times 27 is rendered 29
Times 28 is rendered 29
Times 29 is rendered 29
Times 30 is rendered 29
Times 31 is rendered 29
Times 32 is rendered 29
Times 33 is rendered 29
Times 34 is rendered 29
Times 35 is rendered 29
Times 36 is rendered 29
Times 37 is rendered 29
Times 38 is rendered 29
Times 39 is rendered 29
Times 40 is rendered 29
Times 41 is rendered 29
Times 42 is rendered 29
Times 43 is rendered 29
Times 44 is rendered 29
Times 45 is rendered 29
Times 46 is rendered 29
Times 47 is rendered 29
Times 48 is rendered 29
Times 49 is rendered 29
Times 50 is rendered 29
Times 51 is rendered 29
Times 52 is rendered 29
Times 53 is rendered 29
Times 54 is rendered 29
Times 55 is rendered 29
Times 56 is rendered 29
Times 57 is rendered 29
Times 58 is rendered 29
Times 59 is rendered 29
Times 60 is rendered 29
Times 61 is rendered 29
Times 62 is rendered 29
Times 63 is rendered 29
Times 64 is rendered 29
Is there any way to get the displayed screen fonts consistent with the
printed eps fonts ?
By the way, Ralf found the following report about displayed and printed
fonts: http://wiki.tcl.tk/8483
Thank you all in advance,
Maura
