I also believe that Chester Jenkins at Village is very keen on this feature.

All the faces of Font Bureau's Readability Series have grades, e.g. Quiosco, which can double for bolder weights. Same for Greta Text.

I'm keen on this feature as well. Grades make color so much easier.

Ohhhhh...

So grades = weight duplex?

Here is Galaxie Polaris Book and Bold:

Are these duplexed?

When I have a bunch of numbers they look pretty good. But if I zoom in I see it’s not exactly lined up, then again we’re not even sure if Galaxie is duplexed.

Are grades/duplex text/numerals more difficult to make?

Mike Diaz :-)

Well, grades are designed, according to H&FJ, "using the same set of character widths, so designers prototyping with one font can switch grades later without affecting copyfit." So, yes, typefaces with grades have weight duplexing, albeit in smaller increments than a typical roman and bold, for example.

If I understand your question, I don't think you'll find many typefaces that are duplexed between weights (rather than grades), since that would really mess-up the spacing in many cases. Some monospaced faces are duplexed between weights, and if you look for unaltered digital versions of Linotype faces you'll find duplexed italics, e.g. in Sabon. Another type family that's duplexed is the delightful Klimax.

Different concepts. Grades, at least as defined as H&FJ, are slight weight variations on a single weight, usually used for optimizing the quality of text on different papers or presses. Poynter is another example.

H&FJ is defining a family with duplexed weights as one that shares the same width among all its weights. Other families like this:

Maya Samuels
Delicato
Alwyn
Faricy
Hedley
Mic 32

sorry for messing up the order... I should have made another post :-(

Okay, I’m really confused now. I think I’ll sleep on this and approach this topic in the morning.

Coles, this is a good candidate for a new FontShop FontList.

Delicious (exljbris) has that feature with every character, not just numerals. Change the weight, line length is unchanged. Don't recall if it has tabular digits or not though.

I was under the impression that keeping the same width for tabular figures across weights was standard practice.

Just found one more: Excelsior (aka News 702 in the Bitstream nomenclature).
And given its proportions, it turns out to be very good for web body text.

Else.
