How to convert Midjourney images to 300dpi printable files
I generate poster art in Midjourney but need a reliable pipeline to get true 300dpi CMYK-ready files without artifacts. Looking for upscalers, color conversion steps, and file export tips.

Decide final print size and calculate pixels (inches × 300). From Midjourney, render at the largest output available, then upscale to your pixel target with a high-quality tool (Topaz Gigapixel AI or Real-ESRGAN). Denoise and fix artifacts, open in Photoshop/Affinity as 16‑bit, set 300 ppi, soft-proof and Convert to Profile using your printer’s CMYK ICC, apply final sharpening, then export as TIFF (LZW) or PDF/X with embedded ICC and bleed. Always request a contract proof.
