Print preview
Click to add pieces to the selection one after another. Shift starts a fresh selection. Then choose Move, Copy, or Erase (Delete key erases, Esc deselects). Hand edits are a finishing pass: changing inks or re-separating rebuilds the plates and clears them.
Channels
Each card is one screen. Change its ink color (the base too), hide or solo it in the preview, push its density, choke it, and set how much base goes under it. Click a film to open it full size.
No channels yet. Upload art to rip the seps.
How it works
Upload art, pick the shirt color (or none), and rip it into individual color plates: spot seps for logo art, simulated process for photoreal art on darks. View every plate as its ink color or as the 100% black film, then export at 300 DPI.
Spot seps and simulated process, demystified
A screen print is built one ink at a time: each color in the design gets its own plate, output as 100% black on clear film, burned to its own screen. Spot separation snaps clean logo art to its exact ink colors. Simulated process goes further: it blends a small standard set of inks with halftone dots so photorealistic art prints on dark garments, white underbase first, colors over it, highlight white on top.
Separation Engine does both. It reads your art, picks the ink palette (or you set it), and rips one plate per ink. Flip any plate between its ink color and the black film view, then export press-ready 300 DPI films with the same dot rules as the Halftone Engine.
Your art stays yours
The preview, plates, films and exports are all built in your browser. To pick inks and solve sim seps, a downsized copy of the art goes to the Separation Engine server for that one rip and is never stored or kept.
