Es scheinen wohl mehrere Leute Probleme zu haben. Wenn Du im Partnerbereich US unten den Newsletter über die Masken anschaust, steht da folgendes:
We support SVG, AI and CDR file formats.
Your design must not exceed 15 x 15 inches. We recommend 11 x 11 inches as the ideal size.
Lines and other parts of the design must have a diameter of at least 0.06 inches.
Maximum 3 colors: we can print up to three colors when plotter printing.
Please create each color in your design as a separate layer.
All objects and text to be printed must be converted into paths.
Make sure that all curves are completely closed and do not overlap each other.
Vielleicht hilft Dir das?
