If you're 'echoing the lowercase i's design' and putting a tittle on it, then it's lowercase, and I don't understand the question. And considering that a logo is essentially a design and not text, it's up to your aesthetic tastes and the overall look whether the tittle rises above the height of the other letters or not.

Don't think there would be a "rule of thumb" since you're breaking the normal rules. But there certainly are examples of other companies using unusual capitalization in product names and logos to be distinctive, such as Apple's "i" products (iMac, iPhone, etc.). I remember that when the iMac first came out, some news articles wrote it as "Imac".

Can't offer an opinion about which looks better in your logo without seeing layouts of both versions.

Hi Dave, welcome to Typophile. How about showing us a few sketches first? Just use letters as close to the actual ones as possible, without breaching confidentiality. You’ll find you get better a better response if you show people what you have already tried before asking for help. In addition, it is considered polite to use your full name in your profile. It has also been my experience that if you use your real name as your screen name, you tend to get more and better feedback. Good luck out there, and remember, may the fonts be with you™.

might there be a Turkish connection?

Almost certainly not, since the dot on the I seems to be a discretionary, stylistic decision: ...I suspect that the logotype will be friendlier to read if I dot it. [OP]

Hi typophiles,

Whoa, thanks for the replies! Great, I'll post an image ... Here are two of about a dozen options we're brainstorming for the client. Each also includes an pictograph and a few descriptive words, which I'm leaving out for now.

(The upper typeface is Signika Semibold, the lower is Titillium 25L. On each of them I copied in the "i" dot.)

Dave

The dot might make sense. If the company has to do with people* then the dot being prominent is good; otherwise you can still use a lc structure, just keep the dot within the "rectangle".

The dot on the "m" should go though.

BTW is anybody else getting an uncomfortably strong Meta/Officina vibe from Signika Semibold? Has Anna Giedryś made any other typefaces?

On her website she writes the following, "Being a typical signage typeface it is inspired by typefaces such as Ronnia, Meta, and Tahoma".

Personally I do not see a significant enough resemblance to make me uncomfortable and the competence of her work in general and specific academic background suggest that she is a promising designer rather than an opportunist.

BTW one thing I'd point out here is that the naming of specific inspirations/"inspirations" does not preclude outline theft.

Agreed. I guess I am in a hopeful mood today.

Whatever the method, Signika is clearly conceived as a finessed Meta, not an original design.

In order to distance from the source, some letter proportions have been altered, some terminal constructions changed and overall “softening” applied. It’s all a bit much, no matter how pleasing or effective the finished result, because the design does not establish its own identity—the modifications being piecemeal and unrelated, unable to escape the fundamental presence of Meta asserting itself.

The reason that types such as Gotham and Avenir are successful developments of obvious sources is that, first, they are not informed by so idiosyncratic a design as Meta, and secondly, they restrict themselves to one primary thematic counterpoint to the original.

I think we should start a “Doppelgänger” board.

Thank you for doing that, R.; it seems pretty conclusive to me. :-/

Somebody should ask Giedryś to come clean, and pull the font.

BTW, what is Font Squirrel's policy on things like this?

Thanks ... You're right, aluminum — having the logo read as an acronym is very important to the client.

Karl, interesting thought about ligatured IT: I've uploaded here. Are these like what you had in mind, or something else?

(Re typeface selection, the client is liking Titillium best. Yay.)

Are these like what you had in mind, or something else?

Along those lines but possibly retaining the idea of the lc /i but using the /T to form the dot, which would necessitate some manual adjustment.

Possible inspiration: Dotted I in all-caps.
