Everything you need to know before uploading artwork to the gang sheet builder — file type, background, and resolution.
Upload PNG or JPG files directly in the builder. There's no separate export or conversion step — whatever format your design software saves, drop it in.
A transparent PNG lets your design sit cleanly on the film with nothing printed around it. Anything opaque — including a plain white background — prints as a solid block behind your design, which is rarely what you want on a DTF transfer. If your file doesn't have transparency, the builder flags it and can remove a white background for you automatically, so you're not stuck reworking the file in another program first.
You don't need to pre-size or re-export your artwork at a specific DPI. Once you arrange your designs on the sheet, the builder exports the finished gang sheet print-ready at 150 DPI — the resolution used for the actual print run. Start with the highest-resolution version of your artwork you have; the sharper the source file, the sharper the finished transfer.
There's no fixed limit — it depends on how large each design is and how tightly they're arranged. Small logos at a few inches each can fit dozens per sheet; full-back prints take up most of a 22"×24" sheet on their own. The builder shows your layout as you go, so you can see exactly how much room is left before checkout. See sizes & pricing for the full list of standard and custom lengths.
