Friday Tip: QR codes that actually scan (print edition)

Minimum size: 0.8" (20 mm) square for hand-held pieces; 1.2"+ (30 mm+) for posters viewed from a few feet

Quiet zone: leave at least 4 modules of clear space on all sides (no logos or patterns bleeding in)

Contrast: dark code on light background; avoid low-contrast brand colours and busy images behind the code

File prep: supply vector (PDF/SVG/AI) or a 1000×1000 px PNG at 300 dpi; no JPEG compression

Error correction: use level Q or H if you’re overprinting, laminating, or placing on textured stock

Finish choices: matte or soft-touch laminates reduce glare and improve scan reliability vs high-gloss

Placement: keep flat and away from folds, trim, and seams; don’t curve around bottles or mail panel windows

Distance rule of thumb: code size ≈ viewing distance ÷ 10 (e.g., 2" code for ~20" viewing)

Links that earn their keep: use short, branded URLs; add UTM tags; point to mobile-first pages with a single clear CTA

Proofing: test with multiple phones (iOS/Android), native camera apps, and under mixed lighting before press
