Using the design tool

How do I check text, logos and QR codes?

A final check for readability, contrast, spelling and reliable scanning.

Last reviewed: October 20, 2026

Visual check of file type, logo, text, QR code, colour and transparency

Text

Check spelling, dates, prices, phone numbers and web addresses at 100% view. Use sufficient size and contrast; very thin or pale detail may weaken on textured or absorbent material.

Logos

Prefer a vector PDF or large transparent PNG. A JPG has no true transparency and may include an unwanted white box.

QR codes

Keep a clear quiet zone, never distort the code, use high contrast and scan it from the final preview with several phones. Test the destination as well.

For important business print, have a second person inspect the final preview.
