There are a lot of fonts in the world.
Today I'd like to consider what is a good logo font.
My opinion is simple, good logo fonts are designed for logos initially, not text use.
And it is ideal that the author actually has experience designing logos.
So I think any experienced graphic designer has the ability to create unique logo fonts.
Anyone can create 90% quality logo fonts at least.
From 90%, it becomes exponentially difficult to raise the quality, this theory is not limited to font design work.
And most logo fonts are around 90% quality, customers need the ability to find high quality one.
So my first font name is Qualy, I'd like to express quality typeface with simple naming.
You may think what is the difference between 90% and 100% quality?
I think this is the united quality of curves, so type testing with various words may be useful :)
