Oblique axis Sanserifs
See my comparison in pdf, just follow the link to download a 500 ko file. I don’t have so much humanistic sans in my computer, just Myriad, Lucida Grande and Le Monde Sans. It can be interesting to put there Legato for example, and few others. Please, open the pdf into Illustrator, then save it again, I will put it again on the server without problems!
Sometime, when I refer to oblique axis to students, some of them, who use theses shortcuts, or who can’t see yet counters, use that trick (slanting circles for counters with PS or AI tools). the result is pretty artificial and don’t fit together. Simply because its not just a counter matter, but all the letterform design. The equilibre is done by the interaction between the twos, not just a slanted counter. Try to slant a counter from a o in Frutiger!! and check the result!
Letters are rarely pure circles, more bit round squares, and only true human drawings can achieve that. If these humans see the interaction between the forms and counters. Not always the case, its why its more easy to stick into vertical axis typefaces, there no such problem to resolve.
For writing roots, broad edge pen and so on:
Whatsoever the method used, its purely an intellectual view to say that some typefaces don’t refer directly or not to writing, specially when the result is an oblique axis typeface.
Try to design a human body without any knowledge of the skeleton, you will achieve nothing correct. Latin typefaces rely on the the broad edge pen for many of them. The produced result is another problem, as human body who can take very different appearances, they always rely on same skeleton!
