Being able to upload multiple products is a great feature, but the scaling on the new products is not.
One purpose of a DTG printer, is to get the maximum size print on your substrate / garment.
As a 25 year graphic design and apparel veteran (and DTG owner), I can tell you that having this much variance in your design scaling is not a good idea, at all. In branding we need consistency. With the current method, I now have to make two different designs... my larger, more detailed designs will not work at all.
Hope this gets resolved to where we can actually print as big as the printer allows.
