When it is necessary to use two or more pieces (leaves) of veneer on the same surface, the leaves are aligned at the cut edge. Using different alignments almost limitless and unique visual effects can be attained.
An advantage to using Flat Sliced Veneers, is that the layers are
piled consecutively as they come off the machinery. This allows the
manufacturer to sell the veneer in matched panels, which are
matched together like bookends. This type of veneer matching is called "book match." The resulting veneer joints match in a symmetrical pattern, allowing maximum continuity of the grain across the panel.
Here, the adjoining leaves are slipped out in sequence, but with all
the same-face sides being exposed. The Slip Match produces a
uniform color because all faces have a similar light reflection.
The figure (pattern) in the wood repeats, but the grain does not match at joints. If the grain is not exactly vertical, a vertical slant may appear. If the grain is straight, the joint may not be noticeable
Veneer leaves are placed next to each other in a random order
and orientation, producing a "board-by-board" effect in many
types of wood. Degrees of contrast and variation may change from
panel to panel, and no attempt is made to make the panels match at the joints. Random matching is often done when a rustic look is desired.
Each veneer panel face is assembled from leaves of uniform width
before edge trimming. Panels may contain an even or odd number
of leaves. To duplicate the look in adjacent panels, each leaf is
sequenced and numbered for use in adjacent panels, although the individual leaf distribution may change from panel to panel.
The panel face contains however many veneer leaves it takes to
cover the panel. This is often the most economical way to match
veneer, although it comes at the expense of aesthetics.
Usually, this results in unequal widths and a non-symmetrical appearance. Horizontal grain match cannot be expected. Veneer leaves in a running match are seldom matched in adjacent panels.
