This is a texture produced from a digital scan process, made over a real wood veneer. A veneer technically produced in a factory.

Veneer is a thin slice of wood cut out from a real tree, used for covering furniture, car parts, doors, window frames, etc. It is an Birch veneer with a size of A5 (approximately 8x11.5 inches or 210x297 millimeters) scanned at 600 dpi saved as *.jpg file format without any compression.

The image does NOT contain any color tweaks and it looks just as the dyed Birch veneer looks like.
