Uploading & Organizing Designs

Your design library is the asset. Stores and listings are how you monetize it — the library itself is the thing you're building. Treat it that way from design #1 and you'll thank yourself at design #200.

File requirements that actually matter

• Format: PNG with a transparent background for anything printed on a product surface (apparel, mugs). JPG is fine only for full-bleed prints like posters where the image covers everything.
• Resolution: aim for 300 DPI at print size. For a typical full-front shirt print (roughly 12×16 inches), that means around 3600×4800 pixels. Bigger is safe; PODMACH and providers scale down cleanly. Upscaling a small file is where prints get blurry.
• Color: design in sRGB. Know that printed colors are always a touch more muted than your screen — neon-vivid on screen prints merely bright.
• Content: original work only. No characters, brands, logos, celebrity names or likenesses you don't have rights to. This is the #1 way shops get shut down.

Uploading

Designs → Upload, then drag and drop. Upload the master file — highest resolution you have. One upload serves unlimited products and listings, so there's never a reason to upload a downsized copy.

Naming: the system that scales

At 10 designs, anything works. At 100, "final-final-v3.png" is a catastrophe. A pattern that holds up:

niche - concept - variant → camping - sunset pines - white text, nurse - coffee IV - distressed

You'll be searching your own library constantly from the listing wizard — name for your future self who's typing into a search box.

Portfolio organization

Use the portfolio views under Designs to group work the way your business thinks — by niche, by collection, by season. Two habits worth adopting:

1. Prune ruthlessly. Designs that shame you can be archived; a tight library is faster to work in.
2. Batch by niche. When one camping design sells, you'll want to publish five more — having the niche's designs grouped makes that a ten-minute job.

One design, many products

The library is deliberately decoupled from products: a single design flows onto a tee, a mug, a poster, and a tote as four listings. When you find a design that sells on one product, putting it on four more is the cheapest revenue you'll ever add. The listing wizard makes this nearly mechanical — see The Listing Wizard, End to End.
