You can change where a Onelink leads after the code is printed, so the one thing that has to be right before you print is that the code scans.
- Step 1
Download the right file
For print, download SVG: it is a vector file and stays sharp at any size. PNG L is a large image for print tools that do not take SVG; PNG S is for screens, emails and slides. - Step 2
Print it large enough
Keep the code at least 2 cm (0.8 in) wide for something held in the hand, and larger for anything read from a distance: roughly one tenth of the scanning distance, so 30 cm for a poster read from three metres.Leave an empty margin around the code. Text or artwork touching the code makes it harder to read. - Step 3
Keep the contrast high
Dark dots on a light background scan best. If you style the code or add a logo, keep the dots much darker than the background, never make them lighter than it, and keep the logo small. - Step 4
Test it on paper
Scan a printed copy, not only the file on your screen, with an iPhone and an Android phone, from the distance people will actually be at. If a print shop sends you a sample before the full run, scan that.
