The printed diagrams are printed on high quality 230gsm heavy duty paper (rolled posters), or 150gsm paper (folded posters). The posters can be printed on other substrates, i.e. vinyl, on special request.
The digital downloads are in Adobe PDF format using vector graphics. Vector graphics mean that they can be zoomed and printed into to real life size without loss of resolution.
When you purchase a printed poster you also get free access to the digital download so you can keep it on your digital device. The digital file is available as soon as the purchase clears.
