Font, line width & font size:
In general, you can upload graphics with any font as a motif. So you can stay true to your corporate design in the typography.
However, for good readability and mountability, simple and clear fonts are preferable. This means that fonts with pronounced serifs or delicate line widths should be avoided at all costs.
Due to assembly requirements, the minimum line widths are limited, even for materials that are generally suitable. The approximate minimum font sizes that can be achieved result from this. (see graphic attached)
