Three honest concession cases. (1) Amazon main-image slot one — Amazon's Product Image Requirements explicitly mandate pure RGB 255/255/255 background, the product filling ≥85% of the frame, and rejects any patterned backdrop. Any stripe pattern in slot one gets the listing flagged for catalogue-quality suppression. Use the white-background tool at /white-background/ for slot one, then stripes for slots 2–9. (2) Etsy slot one — Etsy's algorithm rewards lifestyle context and stripes read as catalogue-styling rather than artisan-context, so click-through suffers in side-by-side tests against a styled lifestyle photo. Lifestyle wins slot one; stripes work in slots 2–9. (3) Headshots, portraits, and any photo where the human face is the primary subject — stripes behind a face create a moiré / interference visual artefact at thumbnail size, especially at 22°–45° angles, which under-performs against solid backgrounds in LinkedIn and corporate-bio testing. Use the gradient or solid backdrop tools for headshot work.

The 300-DPI 2400×3600 print preset is the format Printful and Printify both accept for direct-to-garment t-shirt prints, all-over-print apparel, and poster artwork; the file ships as a PNG-24 with full alpha channel at approximately 2.5–8 MB depending on stripe width and source-image complexity (wider bands compress more aggressively because the PNG palette finds longer flat runs). The 2000×2000 sRGB JPEG preset for marketplace catalogue work lands in the 0.4–1.4 MB range, well below the Etsy 5 MB and Amazon 10 MB caps. The 1080×1080 Instagram-square preset at JPEG quality 0.92 lands in the 250–650 KB range, well below the Instagram in-app compression threshold that triggers visible quality loss. The 1000×1500 Pinterest 2:3 portrait preset is sized to Pinterest's published organic-distribution sweet spot. Across these four presets the same stripe pattern recalculates phase to align with each canvas aspect ratio so a campaign deployed across marketplace, Instagram, Pinterest, and print stays visually coherent without per-asset re-tuning.
