Print-on-demand wall art, without the file chores
Printify, Printful and Gelato are the manufacturers. Etsy and Shopify are the shops. The bit in between — masters, bleed, ratios, SKU naming — is where most sellers lose their evening. That's the bit DecoDrop automates.
One master, every size a provider asks for
Each design is upscaled once into a true 300 DPI master, then every listing size is cropped from that same file — so a 16×20 and a 24×36 of the same piece look like siblings, not accidents.

Packs built to each provider's spec
Printify
Canvas and poster providers vary in bleed requirements. DecoDrop exports with the bleed applied and the trim line marked, so you are not guessing per provider.
Printful
Trim-to-size posters and framed prints. Files come out at the exact pixel dimensions for each size at 300 DPI, named so bulk upload maps cleanly.
Gelato
ISO A-series and US sizes side by side. A-series crops come from the same master, so an A2 and a 24×36 stay visually consistent.
The five jobs you stop doing
- Upscaling a 1024 px image to something a printer will accept
- Re-cropping every ratio by hand and hoping nothing important falls outside the trim
- Adding bleed per provider, then remembering which provider needed what
- Renaming forty files so a bulk upload doesn't scramble your SKUs
- Rebuilding mockups every time you tweak the artwork
Why not generate the art in ChatGPT and upload it?
You can — right up until the provider rejects the resolution, or the crop cuts the horizon in half at 11×14.
Generic AI hands you a square
ChatGPT, Midjourney and Canva's generator return a screen-sized image — often 1:1 or 16:9.
DecoDrop treats the ratio as the starting point: 2:3, 3:4, 4:5, 5:7, 11×14 and A-series, each cropped from one 300 DPI master so nothing important gets cut off.
Generic AI gives you one image
Prompt again and you get a different palette, a different light, a different world.
DecoDrop generates a coordinated collection in a single run — same palette, same treatment — because buyers shop sets, not singles.
Generic AI stops at the file
You still have to upscale, resize, mock up and rename before anything can be listed.
DecoDrop continues into room mockups, vendor-ready print packs with bleed, and SKU-named files you can upload straight to Printify, Printful or Gelato.
Common questions
Can you use AI art for print on demand?
Yes, and it is one of the most common uses. The practical constraints are resolution and disclosure: your file must meet the provider's DPI and bleed spec at the size you list, and marketplaces like Etsy require you to disclose AI involvement and list as designer rather than manufacturer.
What DPI do Printify and Printful need for wall art?
Both target 300 DPI at the final print size, with some providers accepting 150 DPI on very large canvas. Multiply inches by 300 to get the pixel requirement: a 24x36 inch poster needs 7200 x 10800 pixels.
Is print-on-demand wall art still profitable?
Margins depend on the product and provider, but the cost side is mostly your time per listing. The economics improve sharply when one brief produces a whole coordinated set with all sizes and mockups, instead of one design at a time.
