Slices of veneer are not usually wide enough to cover the entire surface of a door. Therefore, the veneers are matched together with varying techniques. There are three main types of matching techniques used to make a door’s face look cohesive.
Book Matching: The most traditional method of matching, this look is achieved b y taking successive leaves of veneer and reversing each alternated leaf to bring corresponding opposite edges together in a mirrored effect. This produces a symmetrical balance pattern of grain and figure.
Random Matching: Veneers produced by the same species of wood, but not necessarily the same log are deliberately randomly matched to produce an overall grain effect. The end grain jointing may be introduced in some leaves to add the planking effect.
Slip Matching: Successive leaves are taken from the same stock or log and jointed without turning alternate leaves over as in book matching. This produces a repeat pattern which varies gradually across the panel. This method is usually most effective when straight grain veneers are used.
