Stop the Scroll: 5 Design Tweaks That Explode T-Shirt Sales

About this video

RJ Martinez, who says he has done print on demand for over eight years, claims over 125,000 products sold and over $500,000 in royalties, with one design he says earned over $30,000. He argues most print-on-demand failures are design failures and gives five rules. First, contrast and readability: simple text designs on dark shirts that can be read while scrolling, illustrated with funny dog, tally-mark and matching sweet-potato examples. Second, clear hierarchy: a big headline, a smaller tagline and the main image, as in custom pet and ‘Mother’ style layouts that can be adapted to dad or auntie. Third, color discipline: limit colors, especially if printing yourself, since one-color white or black text is cheaper and prints more reliably than multi-color work. Fourth, styles that print well: thick outlines, badge and sticker styles, and two-to-three-color animal or retro designs, while watching placement on the chest. Fifth, niche mashups: combining trends or holidays, such as Halloween skeletons worn at Christmas or a trending phrase mixed with Christmas imagery, while checking trademarks and not copying listings. He demos an AI workflow by screenshotting a design into ChatGPT for variations such as salty, tired and spicy potato, then builds versions quickly in Kittle using font identification, a color picker, smart boards and background removal, and promotes a Kittle Black Friday discount.

Key takeaways

• Design for the customer: readable at a distance and while scrolling
• Structure designs with a headline, tagline and clear main element
• Limit colors to cut cost and improve print reliability
• Thick outlines, badge and sticker styles tend to print well
• Mash up a trend with a holiday or second niche, without copying
