The quality of a proofing paper is defined by three key factors: optical neutrality, stability under different lighting conditions, and ink handling capacity.

A suitable proofing paper must have a clean, high white point (typically L* ≥ 95 with a* and b* close to zero), ensuring accurate color reproduction. Equally important is the absence of optical brightening agents (OBAs), which can introduce unwanted color shifts under UV-containing light sources and reduce measurement consistency.

Finally, the paper must be capable of handling high ink loads — typically in the range of 300–350% on EPSON-based systems — without bleeding, mottling or loss of detail.

StudioRIP proofing paper is designed to meet all of these requirements. In combination with StudioRIP proofing workflows and properly calibrated EPSON printers, it reliably delivers results suitable for Fogra-compliant proofing.
