There are three types of matching in specifying panel products.
Each of these must be specified an, shown on the design drawings, whenever possible.
Achieved when one piece of veneer is turned over to join the adjacent piece, much like turning the pages of a book (hence the name). This is the most common match resulting in a balanced grain pattern.
A method of matching veneers for the face of plywood where consecutive sheets of veneer are slipped out, side by side and joined together with a repetition of the same grain appearance.
Indicates veneers, either sliced or rotary, are put together for the face of a piece of plywood at random without matching the grain.
Generally done with a straight grain veneer. If a rectangle is divided into 4 quadrants the veneers match at an angle to the quadrant line, and the grain forms a “V” resulting in a diamond shape formed by the grain directions.
Reversed Diamond Match
Commonly done with a straight grain veneer, a rectangle is again divided into 4 quadrants. The grain directions are from the center point to the outside edge in each quadrant, resulting in a series of “V’s” formed by the grain match at the joint line pointed in at the center point.
Most commonly done with a crotch or other highly figured wood. Generally on a round, oval or octagon shaped panel, leaves of veneer are clipped into pie shaped pieces and then book matched. The result is grain pattern repeats which seem to grow out and expand from a center point.
