The core equipment for achieving this goal is a wood grain printing machine (also often referred to as a wood grain roller printer, wood grain gravure printer, or wood grain transfer printer), which is coordinated with upstream units such as dust removal, primer coating, and pre-baking, and downstream units such as curing, varnishing, and embossing.

A furniture wood grain printing machine, also known as wood grain decorative printing equipment, is a specialized printing device specifically designed to transfer wood grain patterns onto artificial boards or wooden components on furniture surfaces using ink or paint.

Wood Grain Printing Machines primarily utilize gravure roller printing, although flexographic/anilox roller metering transfer and digital inkjet direct printing are also available. The corresponding ink categories are as follows: 1. Solvent-based gravure decorative inks 2. Water-based gravure decorative inks 3. UV-curable gravure/flexographic inks (free radical/cationic) 4. Digital UV inkjet inks 5. Screen-assisted inks 6. Thermal transfer/transfer inks

• Single-color wood grain printing machine: Equipped with one printing unit (a set of gravure cylinder + inking doctor blade + embossing roller), it produces one layer of pattern in a single pass. • Two-color wood grain printing machine: Equipped with two printing units, arranged in series. Typically, after the first color, an intermediate curing or short-wave/UV emergency curing period is provided before applying the second color.
