Here at Nutron OSM we can work with most file types, even a scanned sketch.
If you are planning on designing yourself or have something by a third party, follow the artwork submission guidelines below.
If you already have something designed and you have questions contact firstname.lastname@example.org to see if we can work with what you have.
Nutron OSM can also provide templates for producing correct size art files. Contact Hannah to receive the template for your product.
