Enhance QR Readability With a Marker Pen
Improve the readability of QR codes hammered into steel by applying a solid marker.
Apply a Solid Marker
Some cameras have a hard time scanning QR codes off steel - which can be due to low resolution, unsuitable focal length of the camera, or simply bad lighting conditions.
By applying a solid marker like the one we offer here the readability can be improved to same level as a paper QR.
About Our Solid Marker
The marker we offer is a Sakura Solid Marker which contains solidified paint in a marker form. It marks through dust, rust, water – inside or outside on smooth or rough surfaces. Dries within minutes and is permanent once dry. The resulting markings won't fade or wash off easily.
How to Apply The Marker
Simply apply the marker on the desired area.
Wipe the excess marker off leaving only paint in the dimples of the QR. Let it dry up.
