德国采购需求：印章和纸胶带，和纸胶带

We're a small company in Germany looking to produce custom washi tape with a stamp-style design. Each stamp motif will be around 2.5 x 3.5 cm, featuring a white perforation-style border. We're interested in getting some details from you to move forward. Could you give us a pricing estimate for different quantities (10, 25, 50, and 100 rolls)? Also, we need to know the technical specs for the artwork—like preferred file formats, DPI, and any color profile requirements. How many different stamp images can fit in one repeating loop on a single roll? Lastly, let us know what tape widths and roll lengths you offer, along with any size limitations for the stamp-style washi tape. Any extra info would be super helpful!
