Manufactures of board products need a way to ensure that the overall colour of their products are the same from lot to lot.

Production changes can alter the base colour and appearance and the consumer predominately perceives: 

·         Different shades to be off and wrong colour

·         Dull colours can suggest the item is not new or dirty

·         An off colour product may perceive that the product is defect.

The company needs to produce the board products to a certain target as colour & appearance perception influences the customers buying decision.
