AI Designed My Whole Print on Demand Store (Almost Banned)
About this video
He uses Kittl (the video’s sponsor) to generate not one design but a whole matching print-on-demand collection from a niche pulled from his research vault. The key, he says, is consistency: he sets a style reference in Kittl so every generation shares the same style and vibe, writes simple prompts with bold typography, funny phrases and a clean vintage look, and puts exact text in quotes. He then makes each design print-ready in the same window by removing backgrounds and vectorizing, drops them into built-in mockups, and exports transparent files. He warns of one flaw: AI will happily produce trademarked material, so before listing he says he runs every phrase through the free USPTO trademark search at tmsearch.uspto.gov and kills anything registered, to avoid suspension.
Key takeaways
- Build a collection, not a single shirt: set a style reference in Kittl so all generated designs share the same style and look like one brand.
- Use simple prompts with bold typography, funny phrases and a vintage look, with the exact text in quotes so it is spelled correctly.
- Make each design print-ready in the same window: one-click background removal, then vectorize so it scales crisp from sticker to hoodie.
- Use built-in mockups to see the full store before exporting transparent files and uploading them to a print-on-demand platform.
- Trademark-check before listing: he says he runs every phrase through the free USPTO search at tmsearch.uspto.gov and drops anything registered, because listing a trademarked phrase can get an account suspended.
