Correct format

Sometimes SVG files can be used to feed artwork into industry specific production hardware, such as embroidery machines, laser engravers, vinyl cutters, etc. However, I think it's better for the shops doing the production work to export the SVG files on their end. There are multiple flavors of SVG and they don't all get along with various kinds of industry specific software and hardware. A customer could supply an art file in SVG format and it might fail to load. It's usually safer for the customer to supply a more general purpose vector format like Adobe Illustrator AI. The production shop can export SVG files in the specific version needed. Customers still need to follow some artwork submission guidelines to avoid problems when sending art in a format like Illustrator AI. Requirements are going to vary based on what kind of work is being produced.
