Stop wrestling with complex Photoshop channels and expensive trade separation bureaus. Generate true perceptual CIEDE2000 spot separations, choked white underbases, and ready-to-burn halftone film positives directly in your browser.
Engineered for Production Compatibility with Automatic Textile Presses & CTS Systems
Free unlimited channel preflight in browser. Credits only deducted on final high-resolution film positive export.
CIEDE2000 Perceptual Color Delta-E & Spot Indexing
Calculates true optical color difference using the CIEDE2000 formula to extract simulated process spot color separations and white base plates. Generates halftone frequency angles and film positive PDFs with registration targets and gray balance strips.
Human vision perceives color differences non-linearly. OptiPercept uses international CIEDE2000 mathematics to prevent muddy press midtones.
Standard software calculates RGB channel Euclidean distances, resulting in muddy transitions and inaccurate flesh tones. CIEDE2000 calculates color shifts according to true human retinal perception.
Automatically isolates a solid, choked base plate (preventing white flashing on high-speed automatic carousels) plus a separate top highlight white plate for brilliant optical pop.
Rasters each spot channel into 45–65 LPI elliptical dots with pre-calculated screen angles (22.5° offset rosette) and embeds 3-point registration targets and step wedges.
Choose the monthly separation allowance that fits your shop. Unlimited free browser preflight, multi-channel preview, and volume discounts on extra credits.

• 100% Free Unlimited Channel Preflight: Loading simulated process artwork, inspecting individual spot color separations on garment colors, and testing CIEDE2000 clustering thresholds in your browser is completely free.
• Credits Deducted on Export: Credits are only consumed when you download the final production-ready separation files (high-res layered TIFF or screened halftone film positive PDFs). Credit consumption varies depending on separation complexity and channel count.
• High-Value Screen Printing Credits: Each separation credit delivers multi-channel spot color separations with underbase white, highlight white, and halftone angles replacing €30-€60 external manual trade separation fees.
• Dedicated Studio: ScreenSeparations.com subscriptions and credits apply exclusively to ScreenSeparations tools. Printasy UV Studio and DTF Studio require separate subscriptions.
Loading customer artwork, simulating color channels on dark/light garment substrates, adjusting CIEDE2000 Delta-E clustering thresholds, and previewing on-screen simulated separations in your browser is 100% free and unlimited. Credits are only deducted when you perform a final production export (e.g. downloading the high-res layered separation TIFF or screened halftone film positive PDFs). Credit consumption varies depending on separation parameters and complexity.
The human eye perceives color shifts non-linearly, especially in delicate flesh tones, soft sky gradients, and deep earth tones. Standard Adobe channel splitting produces muddy midtones and harsh color jumps on press. OptiPercept CIEDE2000 calculates color difference according to international CIE standards, matching biological human perception to extract clean, vibrant spot colors with smoother press transitions and minimal ink buildup.
Yes. You can output both continuous-tone grayscale separation channels (for your existing RIP) and pre-screened halftone film positives (45 to 65 LPI, elliptical dot geometry, with industry-standard moiré-prevention angle offsets).
No. Subscriptions and credits are dedicated to ScreenSeparations.com tools. To use Printasy UV Studio or DTF Studio, a separate subscription is required.
Yes. Image processing and color delta math run client-side in your browser using high-performance WebAssembly. High-resolution graphics never leave your computer.
Discover why human optical perception models eliminate muddy spot blends and guarantee cleaner underbase chokes in textile screen printing.
