Alwan ColorHub (ACH)

Advanced color management and ink optimization for every print process

Alwan ColorHub (ACH) is a color management and ink optimization server built for images and PDF files, delivering accurate and predictable color no matter which input or output color space and printing process you use — offset, digital, flexo, or gravure.

Dynamic DeviceLinks™ technology

Alwan ColorHub’s award-winning Dynamic DeviceLinks™ technology analyzes each PDF individually, identifying every element’s color description and color space, then evaluates area coverage and ink consumption before building and applying a tailored DeviceLink. The result is more accurate color and more consistent print quality than static, one-size-fits-all color conversions.

Three editions to match your workflow

• Alwan ColorHub PrePress: PreMedia features plus CMYK Dynamic DeviceLink color separation.
• Alwan ColorHub Press: Everything in PrePress, plus GCR (Gray Component Replacement) control.
• Alwan ColorHub ECO: Everything in Press, plus Dynamic Ink Savings for reduced ink consumption.

Every edition can be extended with Hydra Profiling® — Alwan’s patented spectral technology for building accurate ICC profiles from just a handful of printed patches — plus HiFi multicolor separation, Alwan LinkProfiler integration, and other options (see Alwan ColorHub Options).
