As a consultant, I can confirm that rescaled charts are one of the
typical user errors one gets when having a client print a target.
Sure, I've certainly come across it myself.
I'll add the idea of a scale gauge to the wish list, but I'd prefer not to
to meddle with the code to that degree when I'm trying to finalize a release.
The workaround is to create a .TIFF with a slightly smaller size
than the page, and then add a gauge manually with your favorite
pixel editor.
Typically what you want to do is generate a standard target and then
overlay an annotation template and alignment marks in Photoshop,
redimension the whole thing to something like 360 dpi so that a
printer driver like CUPS doesn't apply some weird sharpening or
antialiasing routines to it, and resave the whole thing as a
compressed TIFF which you use forever.
Some profilers work that way. One of the features of Argyll is
tailoring the chart to suite the situation, particularly in regard
to preconditioning with a previous profile.
It might make sense to provide some standard letter and A4 sized
templates of inkjet charts as above for the most used instrument(s).
You can generate a fixed chart if you want, but I'm not convinced many
would use a set of charts that I create. You can always use something
standard like the ECI2002R (see ref/ECI2002R.ti2).
