About under- and overshoot:
for under- and overshoot is it better to have the same values (eg. baseline -16, x-height +16)?
for uppercase and lowercase is it better to have the same undershoot values? Because in some fonts I have found for example that the uppercase is 0 / -16 and the lowercase 0 / -12. Could this result in an apparent imperfect horizontal alignment?
For ascenders isn't a tighter overshoot enough?
In general, is there a way to calculate the under- and overshoot in an absolute sense? I mean: how to decide if the most appropriate value for a given font is 12, or 14, or even 16, etc.?
In metal and phototype, one sees more fine tuned optical alignment, notably in some of Adrian Frutiger’s designs in which flat horizontal strokes as in Zz actually sit below the cap/x-height and above the baseline. I usually align the crossbar of f and t below the x-height for the same optical reason.
But, from the image I am attaching, is it possible to understand if your expert eye does not find the overshoot of lowercase letters too narrow?
The placement of ` on è seems a bit off. I'd move it to the left a bit. And the tittles could go up a bit, I think. Okay I'll stop, please excuse my unsolicited advice
I recheck the alignment on the baseline (the case of | o | and | z | reported to me by @cristóbalhenestrosa.
This is intended to be a text face font, like serifs in general, intended to be printed as well, and not only displayed for example as .pdf.
For accents, @jasperdewaard is right, but the bad accent placement comes from the fact that I switched to the anchor method (it'clear I'm not a font designer, I learn progressively as I do things ...) and postponed the retouching until the base glyph has a definite shape.
One last consideration: Garamonds (Premiere, EB, ...) generally turn out quite small in 12pt print. This is already slightly larger. Does it make sense to increase the size a bit more, with printing as a destination?
Thank you so much for the very useful comments
In a few days I will post a more complete specimen of the Roman in the appropriate section of the site
