Poster Upscale AI is not a partner of Printful, Gelato or any print-on-demand brand. We have independently tested and validated our exports against their quality checks. Final acceptance also depends on your source image: files that have been heavily compressed, watermark-stripped, or already degraded may not reach print quality. Our tests are performed on clean AI outputs (e.g. Gemini, Midjourney, DALL·E).
