The most useful thing a sock supplier can tell you is that your logo, as sent, will not knit. Here is what happens instead of pretending.
The grid is the medium
A knitting machine builds the design from a fixed grid of stitches, and the needle count sets how fine that grid is.
Everything on the sock — letters, lines, icons — is made of those squares.
The stitch floor is real
Below a certain size, letterforms lose their counters and thin rules break into dashes.
No machine setting fixes it; only redrawing at the gauge does.
What redrawing looks like
Thickened strokes, opened spacing, simplified marks — the same brand, restated in stitches.
Done well, the knitted version looks intentional rather than degraded.
Approve the chart
The knit chart is the true proof: what you see is literally what the machine will make.
A supplier proofing from a smooth mockup is showing you a picture, not a sock.
