(i also changed error correction level to the minimum) The current script uses kazuhikoarase/qrcode-generator - from this it seems if you change (Line56ff) # Build Qrcode

It uses segno (Python QR Code and Micro QR Code encoder)

there is a alternative plugin for inkscape i found (did not try).

The QC on silkscreen is a secondary consideration, so you may not have a perfect image every time.

Silkscreen will be interrupted by vias and skewed by any copper planes.

Even with good minimum width spec, the resolution may not be perfect for a larger pattern.

The contrast between soldermask and silkscreen may not be sufficient for code reading, remember you can only apply single color printing (typically white) and the negative is whatever your soldermask color is.

If you ask, the PCB often will be able to print and apply the sticker for you.Ī few things to note that may make a sticker more appropriate However, typically, I have usually seen a sticker used for this instead. My rule of thumb for silkscreen is smallest feature of 1mm or so which eaves you a 10x10 qr code “pixel” grid which is not much. It is hard to say from here without seeing the silkscreen pattern. They should be able to give you their thoughts based on the gerbers.

Best option is to clear with the manufacturer.
