An UltraSeps alternative that does not sit inside Photoshop

What UltraSeps is, as its vendor describes it

UltraSeps is colour separation software sold by Extreme Sportswear as a one-time purchase. When we checked the vendor site on 28 July 2026 it was listed at $399, discounted from $599, and version 3 requires no unlock code to install. The vendor describes the licence as site-wide across your machines at no extra cost, but qualifies that itself as an honour system — it asks shops with multiple users to buy additional copies — so treat it as a trust-based allowance rather than a licence term you can lean on. It runs as a plug-in and automation set inside Adobe Photoshop — the vendor states Photoshop CS3 or higher, full Photoshop rather than Elements — on Windows or Mac, with an Apple Silicon build. The vendor advertises eight forms of colour separation including three separate simulated process modules, custom spot channels, and underbase and highlight white tools, plus a 15-day free trial that the vendor describes as the full previous version rather than a limited build. Prices and versions change; check the vendor site rather than trusting this page.

Where UltraSeps is likely the better choice

If you already own and use Photoshop daily, a tool that lives inside Photoshop is genuinely convenient — your separation happens where your retouching already happens, in channels you already understand. If you run high volumes of simulated process work, a mature package with years of press-tested routines behind it is worth real money, and buying once rather than subscribing suits a shop that hates recurring bills. And a one-time purchase you own forever has an obvious appeal that a monthly plan does not. None of that is something we are going to argue you out of.

Where this is genuinely different

Four differences that are structural rather than a feature list. It runs in a browser, so there is nothing to install and no Photoshop licence required underneath — which matters most on the older art station a lot of shops actually separate on. It starts genuinely free: spot and index separation, ink editing, per-plate preview, and PNG/ZIP/ORA export cost nothing; downloads require a free account. The separator and file writers are client-side, so no artwork pixels are uploaded. Small account and anonymous outcome requests carry metadata only. The free output includes both PSDs: a real layered PSD, and a multichannel PSD with actual spot channels carrying their ink colours and names. Per-plate high-DPI film and the print maths are the paid half; the local spot-channel writer is not.

The cost comparison, plainly

UltraSeps was $399 one-time when we checked, on top of whatever your Photoshop subscription costs. Here you pay nothing to separate spot and index artwork, and the print-ready render — halftones, choked underbase, highlight white, per-ink choke and spread, dot gain, registration marks, optional SVG tracing, CMYK and simulated process — is 10 credits per image with free re-renders of that image for 24 hours. The multichannel PSD with real spot channels is not in that list because it is a local export after free sign-in. Credits come with a monthly plan, or as a one-off pack whose credits never expire — see the pricing page for current prices in your currency. A render is 10 credits an image. Which model is cheaper depends entirely on your volume, and if you separate constantly the one-time purchase will win eventually.

What we do not have

We are new at this and they are not. We have no decades of accumulated press-tested presets, no Photoshop panel to work inside, and no built-in print driver — we output raster plates and film, local spot/index PSDs and optional SVG traces where a plate is suitable, and your existing RIP or workflow takes it from there. If you first retain a local Spot or Index palette, its whole-channel density sliders can feed a Simulated-process render; a direct render has no editable channels in the workspace, and neither path offers the per-channel tone curves a mature package can provide. Difficult photographs can still need downstream work or a human separator. Exports add no watermark or tier-based downscale; unusually large source art can still be fitted to the current device's memory ceiling before separation.

How to decide with one real file

Take a real job off your queue — not a clean vector logo, an actual customer file. Run it here for free and look at the plates: is every letter of the lettering on one screen, are the edges clean, is the ink count sane. Then download UltraSeps' trial and run the same file. You will learn more from that than from any comparison page, including this one. Both tools being free to try is the point; the time required depends on the file, machine and how much channel work the result needs.
