Abstract:
1. Method for manufacturing multi-laminar patterned wood sheets having patterns of defined shapes and dispositions on their side faces, in which said patterned wood sheets are cut from a multi-layered flitch of superimposed and glued base wood sheets, comprising the steps of: printing a basic pattern on a side surface of the base wood sheets using a printing solution comprising a colouring agent; controlling a depth of penetration and a spread of diffusion of the colouring agent into the base wood sheets during said printing step by maintaining the temperature of a printing bath containing the printing solution, drying the wood to a specific moisture content and using a printing solution having a pH value; composing the flitch comprising said printed wood sheet; and slicing laminar wood sheets from said flitch, wherein increasing the moisture content of the wood increases the spread of diffusion of the coloring agent, wherein increasing the temperature of the printing bath increases the depth of penetration into the wood, and wherein increasing the pH to an alkaline value increases the depth of penetration into the wood, while decreasing the pH value to an acid value decreases the depth of penetration into the wood.
