Elemaints - A Serif Family with Optical Sizes

in Type Design Critiques
A long time ago (2010) I have started a new typeface written in METAFONT (see http://www.typophile.com/node/73827). I interrupted the work because I had to investigate further in METAFONT and parametric type design (e.g. https//www.tug.org/TUGboat/tb37-3/tb117romer.pdf or https://tug.org/TUGboat/tb35-1/tb109romer.pdf or http://typedrawers.com/discussion/2342/funtauna-rectangular-slab-serif).
But I have never abandoned the original project and have always been working from time to time for this typeface. Taking the updated METAFONT sources, I have produced some master fonts. At the moment, work is concentrated on 2 of them: The display face and the tiny face.


I have refined both faces in Fontforge and have interpolated the optical axis Tiny-Caption-Regular-Subhead-Display:








      

The intended use of the typeface (which I call Elemaints) is the use in scientific texts. The glyph forms are mainly based on french renaissance antiquas like Sabon or Albertina. The x-height is equal to the x-height of Times New Roman. The proportions are very similar to Minion. Therefore, the look of Elemaints may resemble Minion, altough every single glyph was constructed freshly. One intended difference to other french renaissance antiquas may be the serifs, which always end rectangular:


Elemaints is not meant to be a revolution but a free antiqua with optical sizes for scientific texts.

Any suggestions (except kerning, which is not done yet) are welcome (glyph shapes, proportions, rhythm, details, spacing, ...).

    Your “tiny” size currently seems to me to be optimized for regular text, like maybe 10 pt in print. I would not call that tiny, and more importantly, you might use/need quite a lot more optical adjustment if you wanted to go down to 6-7 pt, or handle super-/sub-scripts, or the like.

    Looks promising so far.

    I'm getting the impression that the spacing is still a bit uneven, especially in the «Heavy boxes» Display text. Perhaps a touch too tight for small text in general?

    As for letter shapes, the /a strikes me as a bit pinched/pointy on top, and I'm not too fond of /a terminals that curve into the counter space, but that may just be me.

    @Thomas Phinney Upon your suggestion I have made the lower optical sizes more extreme. The following picture shows the old and the new version in comparison with Computer Modern and AMS Euler:



    Do the new optical sizes go in the right direction?
    What optical adjustment need to be improved? Width? Darkness? Contrast? Serifs? Joints? Ink Traps?
  • Linus RomerLinus Romer Posts: 43
    @Christian Thalmann I have changed the shape of the a (terminal is now a tear drop, the top is less pointy):




    I have increased spacing for the Display face (whitout any manual adjustments yet):
    (upper image = old, lower image = new)


    Would you give it even more space between the glyphs?
    I did not understand the expression «Heavy boxes», did you mean counters?

    I think it was the smaller optical sizes, not the Display cut, that needed more breathing room. 
    "Heavy boxes" referred to the text settings in the examples you posted. 
  • Linus RomerLinus Romer Posts: 43
    @Craig Eliason @Christian Thalmann Stupid me, now I understand the "Heavy boxes perform..." :)
    I will have a look on it again...

    I much prefer the new terminal on /a. The top of /a still looks rather pointy to me, but on further thought, it might be a symptom of the glyph's rather narrow width in general, especially compared to /e. Maybe try out a slightly wider version to see how it feels?

    (Garamond gets away with a super-narrow /a design, but it is helped by the extra space opened by the rather generous outstroke.)

    As for the spacing, I was actually referring to the «Heavy boxes» sample text in the Display cut, especially the /e/a combination:
    But maybe the problem just lies in my judging a Display cut at text sizes.  :grimace:
  • Linus RomerLinus Romer Posts: 43
    @Christian Thalmann I have completely renewed the spacing of the display face. I have also made a wider variant of the a, but than I went back to the narrower variant and made again a bit less pointy:



    What do you think about the spacing? What about the narrow/wide a?
  • Thomas PhinneyThomas Phinney Posts: 1,771
    The spacing seems too loose overall for a display face. It is spaced more like a text face, now.

    The "ea" combo seems tighter than most everything else. The "new" spacing of "ea" is a decent match for the "old" spacing of the rest of the font. But because you make the "ea" combination the centerpiece of much of your spacing demos, it is hard to judge overall spacing.


  • Linus RomerLinus Romer Posts: 43
    Okay, I have again renewed the spacing of the display face and changed the shape of the "a":






  • Linus RomerLinus Romer Posts: 69
    For the caption face I now have filled the empty encoding slots such that all the LaTeX letters, symbols and extenders are covered now. The first thing of the mathematical glyphs I want to ask here is about the digits (tabular figures):



    The image above shows 4 (probably still suboptimal variants) for the digit one. The digit one and the letter "l" should be distinguishable at first sight (also in small sizes):



    And the digit one should be relatively wide in order to fill the gaps in tabular figures. I aesthetically like the 3rd variant, which unfortunately is the least distinct variant compared to "l".
    Which variant would you prefer?
    (And of course any other suggestion related to the digits presented here is welcome.)
  • Craig EliasonCraig Eliason Posts: 937
    Baseline serif on those 1s could be wider
  • Linus RomerLinus Romer Posts: 69
    @Craig Eliason I have increased the baseline serifs for the 3rd variant and I quite like it now:

  • Christian ThalmannChristian Thalmann Posts: 1,480
    Yeah, that /one fits best for some reason.
  • Ori Ben-DorOri Ben-Dor Posts: 286
    I think the top of /1 needs more stress. At small sizes it fades away.
  • Linus RomerLinus Romer Posts: 69
    @Ori Ben-Dor Like this? (The width of the smallest part of the head was increased by 11%.)

  • Ori Ben-DorOri Ben-Dor Posts: 286
    Yeah, that's better.
  • Linus RomerLinus Romer Posts: 69
    The design of the greek letters is based on the shapes of Hermann Zapf's Euler typeface. Do they look coherent?

    I am no expert, but here are my thoughts.
    I think the alpha could be maybe a little tighter, by which I mean the crossing could be just a tad more upright. Just a touch.
    I think the knots on zeta and xi are not convincing. Also, the entry could be a bit more pronounced, and the bottom could be a bit more relaxed, a little more akin to final sigma (although still probably a bit flatter).
    To me, the head serifs on eta and kappa seem a little contrived in this context. I wonder if these entries shouldn’t just be more natural like gamma, nu, upsilon, psi, et al.
    The bottom of left leg of pi could be just a tad heavier.
    I’m not sure about the alternate pi (ϖ). I’m not familiar with how Zapf handled it, but I would be inclined to end the stroke with a return to the right to make more of a top stroke.
    The descender of alternate rho seems congested to me. I would extend the left stroke a little further before entering the turn, perhaps cheating the bowl up a touch.
    The cursive phi could be more open. I’d round out the lower left a bit more and widen the right.
    I feel like the omega needs more curl to the arms. And the left bowl looks too narrow to me.
    The stem of the capital Phi could extend a bit below the baseline and above the cap line. Right now it looks short and cramped.
    Others may see things differently.
  • Linus RomerLinus Romer Posts: 69
    @Kent Lew Thank you for your detailed advise! Here are the improvements:



    About zeta and xi: I have made 3 variants. The middle variant has a different pen angle. I would prefer the middle variants but I fear they do not fit with the rest because of the different pen angle.

    About pi-variant: There are not too many existing examples of pi-variant. After reconsidering the shape, I have found it would be better to use a flat top.

    About Phi: Instead of moving the terminals of the stem, I have squeezed the mid circle.

    Now the Greek alphabet looks like this:



    What do you think about these improvements?

  • Christian ThalmannChristian Thalmann Posts: 1,480
    Very pretty, all in all!

    I find the tiny gap at the bottom of /beta a bit irritating.  What would it look like if you closed it?

    I'm also getting the impression that some small pieces of some letters are too rigid to fit into the lively overall rhythm of the Greek lowercase. For instance, the baseline diagonals of /zeta and related letters, the downstroke of /xi, the middle stem of the /omega-like /pi, and the downstroke of chirographic /theta. Allowing them a bit of a curvature might improve that.

    Are the fonts available online?

     I'm curious to read the MetaFont sources too :)
  • Linus RomerLinus Romer Posts: 69
    • the closed /beta looks better to me (and also now seems a bit wider, but this is okay), thanks for the tip! Is the joint too dark now?
    • the curves for /zeta /xi, /sigma-final, /pi-variant-like-omega, /theta-script are a bit more relaxed now (for the theta-script the change is now quite small, did you really mean the left stem?)
    • pi is a bit wider now in order to fit the rest of the Greek letters 

    @Dave Crossland The fonts are not available online yet but I might post an alpha of the Caption face in this forum as soon as the shapes are fixed. When the whole family is ready, I will probably publish the family on CTAN.
    The METAFONT sources will not go public, because I have now made many additional adjustments by hand.

    Yes, /beta is better now.
    I wonder if the recurved mini-descenders and the tops of /zeta and /xi are now a bit too flamboyant. Maybe setting them in text would help figure that out. I'm sure they'd fit great into the italics, though.
    The curves of /varpi are still a bit strained, like a pair of clenched buttocks, if you'll excuse the simile. I'd lower the left and right extrema and try to reduce the rigidity of the /T-shaped structure in there.
    Yes, I mean the left stem of /vartheta. As far as I can tell, the glyph is supposed to mimick the overall shape of the geometric /theta, so the top and bottom extrema should be more or less centered with the glyph's center of gravity.
  • Dave CrosslandDave Crossland Posts: 1,051
    Aha, ok... Isn't a pity to not publish them as a learning resource, since there are so few MetaFonts? :)

    Will you use the SIL Open Font License?
  • Linus RomerLinus Romer Posts: 69
    @Christian Thalmann I tried to follow your advise. For /varpi I disconnected additionally the mid stem from the top bar. (And still I just cannot unsee the buttocks since you mentioned them ...)



    I think the new /zeta and /xi fit better with the rest but the top curl still needs refinement. What do you think?

    @Dave Crossland  The sources would have little value without any documentation. I will consider writing a TUGboat article about the evolution of Elemaints (including some METAFONT techniques) when the faces are ready.

    Hmmm, the new top of /zeta and /xi looks very unfinished indeed. I actually like how the old version confidently marks the ascender line, whereas the new version just begins in the middle of nowhere. (Then again, I've been told that Greek lowercase extenders not aligning with each other is a feature, not a bug...)
    The /vartheta is a step in the right direction, but it still looks oddly /D-shaped to me when I'd expect something /O-shaped. It might also stand to be a bit wider.
    The new /varpi are much better.
    The top of /delta strikes me as puny.
    (Disclaimer: I am not at all an expert on Greek.)
  • Dave CrosslandDave Crossland Posts: 1,051
    BdullBril!! Really looking forward to seeing it :))
  • Linus RomerLinus Romer Posts: 69
    @Christian Thalmann I will return to /zeta and /xi a bit later. So here are new versions of /vartheta and /delta (in the rhythm old new old new):



    What do you think? Is the head of the delta now less puny?
  • Kent LewKent Lew Posts: 896
    δ definitely looks better to me.
