A Redditor wanted a retro CMYK halftone (Ben Day dots) effect for images but only found an $80 Photoshop plugin, so they vibe-coded a free ComfyUI custom node called CMYK Magic with Claude.
- Built on real printing specs, drawing on a detailed blog series about the history of Ben Day dots
- Fully customizable, with 37 presets and 17 dot patterns
- Installable via ComfyUI Manager or manually from GitHub (ComfyUI-CMYK-Magic)
- Author notes it's imperfect, as vibe-coded nodes often are, and invites feedback
