Brown IEC 60350-1 Ed. 3.0 shade prints

The CIELAB defined colours are printed on EFI 9120 XF matt proofing paper according ISO 12647-7:2016 simulating PS5 (print substrate 5 according ISO 12647-2) as spot colours and are within the tolerances for printed spot colours ΔE00 ≤ 2,5 under D50 M1 (0°:45°) measurment condition.

Proof GmbH is a listed supplier for reference colours as proof prints according to ISO 12567-7

You can order the prints either with or without a protective laminate on the reverse. 
The side with the colour fields is always without laminate. The laminate is only applied to the back of the prints. This makes the colour swatches more resistant to moisture and steam on the reverse side. 

The laminate is PVC-free and has a water-based adhesive. It is characterised by high dimensional stability and almost no shrinkage.
