Free sample sep for print shops
Send us one job. Get film-ready seps back.
For screen printers, artists, and merch brands with a press to run. Upload your own artwork — the original file, not a photo or screenshot — and you get separations back within 24 hours, free: one film per ink, halftoned, with a choked underbase and plate labels, ready for your RIP or film printer. No card, no account. Judge us by the films.
We don't print shirts. You'll need screens and a press to use what we send back.
How it works
Three steps to the exposure unit
STEP 01
Upload your art
Drop in a PNG, JPEG, or PDF. PrintSeps reads the artwork, detects the best ink set, and matches each color to the closest Pantone solid — before you've mixed a drop of ink.
STEP 02
Dial in the channels
Review each plate on screen: reorder inks, merge channels, set halftone LPI and angles, adjust dot gain, and choke the underbase for dark garments.
STEP 03
Download film-ready files
Export one PDF per channel — or a layered PDF — with registration marks and plate labels. Send it straight to your RIP, inkjet film printer, or CTS unit.
Features
Everything between artwork and mesh
Simulated process separations
Photorealistic art rebuilt from halftones of 4–8 standard inks plus underbase — full-color results on black shirts without CMYK guesswork.
Spot color separations
Clean vector-sharp plates for logos, lettering, and flat-color designs, with automatic trapping where colors butt.
Pantone matching
Every extracted ink is matched to the nearest PMS solid coated color, so your quote and your ink room agree.
Underbase & choke
Auto-generated underbase white with adjustable choke, plus a highlight white plate when the art calls for it.
Halftone & dot gain control
Set LPI, angle, and dot shape per plate, with dot gain compensation tuned for your mesh counts and press.
Instant color count for quoting
See the ink count seconds after upload — quote the job while the customer is still on the phone.

FAQ
Questions from the shop floor
Can I try PrintSeps before paying?
Yes, two ways: send one artwork file and get finished separations back free within 24 hours (no card, no account) — or start the 30-day free trial. The free sample is real production output, made from your art.
Do you print shirts?
No. PrintSeps makes the films: one halftoned positive per ink, ready to burn onto screens. You need a screen printing setup — or a shop that has one — to turn them into shirts. We also only separate artwork you own or have the rights to print, from the original file, not a photo or screenshot of a finished product.
What's the difference between spot color and simulated process separations?
Spot color separations split artwork into a small number of solid ink colors — ideal for logos and text. Simulated process rebuilds photorealistic art from halftones of 4–8 standard inks plus an underbase, so full-color-looking designs print on dark garments with plastisol or water-based ink.
Do I need Photoshop or a plugin?
No. PrintSeps runs entirely in the browser. Nothing to install, no actions to run, no plugin that dies with the next OS update.
What files can I upload?
PNG, JPEG, and PDF at launch, with AI and PSD support planned. High-resolution raster art — 200 dpi or more at print size — gives the best simulated process results.
What do I actually download?
Film-ready output: one PDF per channel or a layered PDF, with halftones at your chosen LPI and angle, registration marks, and plate labels. Send it straight to your RIP or film printer.
Does it handle underbase and dot gain?
Yes. PrintSeps generates a choked underbase automatically and lets you set dot gain compensation per channel, so seps hit the mesh the way they left the screen.
How does the free trial work?
Card required, $0 due today. We onboard shops in waves to keep separation turnaround fast — your 30-day trial clock and billing start when your workspace opens, not before. Cancel anytime with one click from your Stripe confirmation email.
