Redesign T-Shirt Mockups to Print-Ready Files with GPT-4 Vision & Imagen 4

This n8n workflow automates the redesign of T-shirt mockups into professional, print-ready files. Starting with a user-provided image link, it leverages OpenAI's GPT-4 Vision to analyze key elements like characters, text, layout, style, and composition. An AI agent then crafts an enhanced, JSON-safe prompt that preserves the original intent while improving visuals, typography, and removing mockup artifacts like collars or shadows, ensuring output on a pure black background.

The process includes text escaping via JavaScript for API compatibility, followed by image generation using OpenAI's gpt-image-1 model or Google Imagen 4. This results in high-quality graphics optimized for direct printing on black T-shirts, saving designers hours of manual refinement.

Ideal for print-on-demand businesses, e-commerce sellers, and graphic artists, it boosts efficiency, ensures consistency, and scales production. Benefits include cost-effective AI automation, reduced errors, and rapid iteration from concept to print-ready files, with potential integration into chat interfaces for seamless workflows.
