Mac

Turn any artwork into press-ready color separations — spot inks, simulated process, underbase and halftone films, all from your Mac. SepForge turns your artwork into press-ready color separations for screen printing — right on your Mac. Load a design, choose how to separate it, fine-tune every channel, and export the film positives your shop needs to burn screens. From bold spot-color graphics to photographic, painted, and selective-color artwork, SepForge gives you the control professional separations demand. SEPARATION METHODS • Spot Color — map your artwork to a named ink library with automatic matching, per-ink overrides, and custom colors • Simulated Process — reproduce photographic and painted art with smooth, blended tones • Spot Separation — for selective-color art, like a red subject over a black-and-white scene: each ink prints only where its own color appears, keeping every channel clean with no cross-contamination PER-CHANNEL CONTROL • Channel Levels — adjust Black Point, White Point, Gamma, and Ink Limit on any channel to deepen shadows, recover detail, or reduce ink • Non-destructive, with a live preview BUILT FOR THE PRESS • Automatic white underbase for dark garments • Highlight and neutral-black channels • Halftone dot control — LPI, dot size, and dot-gain compensation • Soft-edge control and ink-density tuning PROOF BEFORE YOU PRINT • Live color proof showing exactly how your separation will print • Per-channel preview in real ink colors • See your full ink list before you commit PROJECTS & EXPORT • Save your work as a .sepforge project — the image and all settings, reopenable anytime • Export print-ready films as PNG (one per channel) or a single multi-page PDF, sized to your press DPI with registration marks and channel labels SepForge is free to explore — separate, preview, and proof at no cost. A SepForge Pro subscription unlocks film export (PNG and PDF). Perfect for screen printers, print shops, and anyone producing separations for silkscreen. --- Privacy Policy: https://splashroad.com/privacy-policy/ Terms of Service: https://splashroad.com/terms-of-service/

  • This app hasn’t received enough ratings or reviews to display an overview.

New in this version: • Spot Separation — a new separation mode for selective-color artwork (like a red bus on a black-and-white scene, or a spot-color logo over a photo). Each ink prints only where its own color actually appears, so channels stay clean with no color bleeding between them. • Channel Levels — per-channel tone control. Fine-tune Black Point, White Point, Gamma, and Ink Limit on any individual channel to deepen shadows, recover detail, or reduce ink — non-destructive, with live preview. • Projects — save your work as a .sepforge file (image and all settings included) and reopen it later exactly as you left it. • Ink Density control for Simulated Process, to tune overall ink weight and shadow depth. • Deeper blacks in the built-in ink library for richer shadow detail, plus clearer separation between preview-only and film-export controls. • Stability and usability improvements.
