The present invention relates to a laser positioning system for an aperture-processing machine and is an accessory of an aperture-processing machine. A plurality of the LCD source driving circuits are typically disposed along a side of an LCD panel and drives the LCD panel in response to digital image signals, such as color signals R, G, B, and control signals received from a control circuit. The cameras can be forward or side mounted to the submersible platform and can include optical cameras, acoustical cameras or both. Otherwise, after the partition valve is opened, a carrier carries a heat body through the inside opening, thereby contacting the substrate onto the heat body in the second area. Furthermore, when the power is in the OFF position, the thumbnail images stored in the buffer memory can be deleted. Also disclosed herein is a method for forming a printed article and an inkjet printing system using said photo-curable ink composition.
