Sizing and printing
How big to print, how much clear space to leave, and how files become physical prints.
Colors and design
Brand colors, gradients and logos, and how far you can push them before scanning suffers.
Reliability
Making sure a code works on the day it's printed, and years later.
Guides by use
The same principles applied to specific places codes end up.
Put it into practice
The generator applies all of this as you design: a four-module quiet zone, contrast and density checks, error correction sized to your logo, and a scan check on the real artwork.
