RAL make products in a range of prices which are suitable for different end uses.
The cheaper RAL fan decks are produced by printing in four colour digital printing, these are not official colour standards. Suitable for client colour selection and for constructors to use when out and about RAL fan decks are colour guides. Printing is a lower cost production method than the coated process which produces the higher priced fan decks and the individual standard cards. The coated process produces a higher accuracy of colour reproduction from one product to another and these products are colour standards for quality control.
The RAL colour standards are supplied with the relevant XYZ colour space data and reflectance curve.
