Color Rules 11: RGB Camera versus Spectral Scanner Featuring Jack Frank

RGB vs Spectral Scanning: A Pressroom Perspective

What’s the best way to maintain color consistency in print production—an RGB camera or a spectral scanner?

In this quick but insightful video, Jack Frank from WestRock shares why they rely on the LithoFlash RGB camera, which reads color density in real-time, to keep color consistent throughout every run.

Jack breaks down:

• Why spectral scanners aren’t always ideal in a live press environment

• The importance of measurement conditions like M0 vs M3

• How RGB data supports efficiency and consistency from job to job

• The hybrid approach that gives WestRock the best of both worlds
