摘要： A platemaking apparatus (100) using laser engraving, a control system, a platemaking method, and a storage medium, which belong to the field of laser beam machining. The platemaking apparatus (100) using laser engraving comprises: a base (10); an XY motion platform (20), which is arranged on the base (10) so as to move transversely and is used for bearing a printing plate; a support platform (30), which is disposed on the base (10), a movement space being provided between the support platform (30) and the base (10) and allowing for transverse movement of the XY motion platform (20); a plurality of laser machining assemblies (40), the laser machining assemblies (40) being connected to the support platform (30), and at least a portion of the laser machining assemblies (40) being adapted to move relative to the support platform (30) and being used to perform laser engraving on the printing plate. The plurality of laser machining assemblies (40) are provided, such that laser engraving operations can be performed simultaneously so as to increase the platemaking speed. At the same time, the laser machining assemblies (40) are configured as movable structures, so that each laser machining assembly (40) can work independently, and different image or text content may be engraved on the printing plate in respective corresponding areas, thus allowing for completion of engraving of the entire printing plate.
