Every tool a separator needs,
in one desktop app
Four separation engines and a full production toolkit — designed around the way real screen-printing shops work.
Spot Color
Detect every color in your design and separate it into individual print-ready channels — with a live proof preview, dedicated black layer and automatic white underbase for dark garments.
- Automatic color detection
- Live proof on any garment color
- White underbase generation
- Merge & refine channels
CMYK Halftone
Convert full-color photography into crisp four-color halftone plates. Correct cyan, magenta, yellow and black screen angles keep your print moiré-free, with control over LPI, dot gain and ICC profiles.
- True 4-color separation
- Moiré-safe screen angles
- Adjustable LPI & dot gain
- ICC color management
Monotone Halftone
Generate a single-color halftone screen with full control over angle, frequency and tonal gamma. Output positive or negative — ideal for one-color jobs and simulated-process underlays.
- Positive or negative output
- Custom screen angle & LPI
- Tonal gamma control
- Perfect for 1-color jobs
Vector & Flat Art
Separate SVG, vector PDF and flat raster artwork by color. A built-in preflight grades how print-ready your file is before you commit, then renders clean per-color layers.
- SVG & vector PDF support
- Flat-art raster workflow
- Preflight quality grading
- Clean per-color layers
Print-shop features, baked in
The details that turn a separation into a clean, repeatable print.
White Underbase
Automatically build a choke-adjusted underbase so colors stay vivid on black and dark garments.
Registration Marks
Drop in precise registration targets on export or print so every screen aligns on the press.
Screen Angles & LPI
Standard moiré-safe CMYK angles with adjustable lines-per-inch to match your mesh count.
Custom Spot Colors
Match each channel to your exact target ink — define spot colors by RGB, CMYK or hex from a built-in swatch library.
Live Proof Preview
See a composited proof on any garment color before you commit a single screen to film.
Film & Direct Print
Print film positives straight from the app, or export press-ready PDF, TIFF and PNG.
Custom Print Sizing
Lay out separations for A4, A3 and A3+ — or set any custom size — with accurate scaling and print bounds.
Vector Preflight
A built-in grader scores how print-ready your vector or flat artwork is before separating.
Real-Time Progress
A responsive progress bar with cancel support — the window never freezes mid-job.
Fast, native and fully offline
Color Sep Pro is a real desktop application — not a browser tool.
Native engine
Image processing runs on a fast, compiled native engine with in-memory layer merging for second-scale results.
Offline by design
Your artwork is processed locally and never uploaded. A connection is only used to validate your license.
Automatic updates
New separation improvements and fixes arrive through a built-in updater while your license is active.
