AI-Generated Modern T-Shirt Design

I want to harness AI to create a series of modern, minimalist T-shirt graphics. The core goal is to set up an efficient, repeatable workflow—whether through a fine-tuned image-generation model (e.g., Midjourney, Stable Diffusion, DALL-E) or a custom script that feeds design prompts and exports print-ready files.

Here’s what I need from you:
• A lightweight AI pipeline that turns short text ideas into clean vector or high-resolution PNG designs (transparent background, 4500 × 5400 px preferred).
• At least five unique shirt graphics that demonstrate the system’s capabilities, all adhering to a sleek, uncluttered aesthetic.
• Source files and clear instructions so I can continue producing new designs without additional coding.

Acceptance criteria
1. Each design must align with a modern, minimalist style—limited color palette, crisp lines, no vintage textures.
2. Output files pass Merch by Amazon resolution checks and look sharp on both dark and light fabric previews.
3. The workflow is documented step-by-step and can be reproduced on a standard Windows or macOS machine with mainstream AI tools or open-source libraries.

If you have experience blending AI image generation with apparel graphics and can deliver a turnkey process, I’m ready to get started right away.
