Alwan-Caldera Multicolor Proofing System

What is Alwan-Caldera Multicolor Proofing System?

Multicolor printing – also known as HiFi and ECG (Extended Color Gamut) – has been developed to print spot colors on printing systems by using extended gamut process inks instead of spot inks (Pantone®).

The muticolor separation – usually CMYKOGV – generated by color management software such as Alwan ColorHub is able to simulate more than 85% of Pantone® swatchbook on a multicolor conventional press within a ∆E00 of 2.

In order to print a job, prepress departments and press minders need a hardproof that visually matches the printing process output.

Alwan-Caldera Multicolor Proofing System has been designed by Alwan for the purpose of producing ISO 12647-7:2016 compliant contract proofs.

What makes Alwan-Caldera Multicolor Proofing System unique is the easiness of use and maintenance.

A single Alwan Hydra® profiling chart is used throughout the whole process; that is, to profile both your proofer and your production press.

Therefore, every time that you have a new printing condition – such as a new paper, a new set of inks, etc. – Alwan’s Hydra® Profiling technology provides you with the easiest and fastest way to update your proofer or your press profile.

How does Alwan-Caldera Multicolor Proofing System work?

Alwan-Cadera Multicolor Proofing System requires 4 components:

  • Alwan ColorHub 6.6+
  • Caldera RIP 12+
  • Alwan PrintVerifier 6.1+
  • Any multicolor proofer supported by Caldera RIP 12+
    (Epson SureColor series recommended)

Alwan-Caldera Multicolor Proofing System manual will guide you step-by-step in the installation process:

  • Create a proofing setup in Caldera RIP;
  • Build a Hydra® profile for proofer and substrate using Alwan PrintVerifier and Alwan ColorHub; and
  • Color manage and assess conformance using FOGRA 7-color media wedge using Alwan ColorHub and Alwan PrintVerifier.
