Without going too much into technical details, many providers of T-shirt shops distinguish genuine designs (often called vector designs) and "simple" text when it comes to printing on shirts and stuff. For example, it depends is a genuine design drawn by hand and then converted to a digital vector design suitable for printing. Whereas don't! provoke me! is simply text printed in Arial font.
Unfortunately, text designs do not show up in the list of designs (Motive) of the shop itself, and the text on the thumbnails of the shirts is often too small to get an idea of what it might look like. Therefore, we include sort of previews of text designs in our postings of all designs by contradicTshirts.
