One Kittl Prompt = A Print-Ready POD Design… But Everyone's Picking the Wrong AI Mode

About this video

He demonstrates making a print-ready print-on-demand design in Kittl (the video’s sponsor) from a single prompt, arguing the common failure is picking the wrong AI model, not writing a bad prompt. Because, he says, selling POD designs on Amazon Merch and Etsy are usually text-led, he uses a prompt for a retro distressed design reading “World’s Okayest Fisherman” with the exact text in quotes, a style description, and ‘isolated on a plain background.’ He deliberately chooses Ideogram 3, which he says is built for typography and layout, over photorealism models, then in the same window removes the background, vectorizes the result, optionally upscales it, places it on a built-in mockup, and exports a transparent PNG for upload.

Key takeaways

• For text-led POD designs, he recommends Ideogram 3 as the default model because he says it is built for typography and layout and spells text correctly.
• Put the exact shirt text in quotes in the prompt, describe the style, and add ‘isolated on a plain background’ to save a cleanup step.
• He reserves Flux or image models for photorealistic art and scenery, and context/Nano Banana models for editing, restyling, or fast concepting.
• Inside Kittl he removes the background, vectorizes (choosing the number of colors, up to 16 in his demo), and can upscale — all without downloading and switching tools.
• Finish by dropping the design onto a built-in mockup, then export the transparent PNG to upload to Amazon Merch, Etsy, or his own site.
