Abstract: A printing system and a printing method, in which precision of a printing process may be enhanced, the printing system may include a controller configured to generate printing data, a user device configured to generate a first control command, generate modulation data based on a user input, and generate a second control command based on the user input, an additional controller configured to receive the printing data and the second control command and generate a driving signal based on the second control command, and including a memory storing waveform information received from the user device, and a printing device configured to perform a printing operation based on the driving signal.

Abstract: A method of inkjet printing includes applying a driving signal to a head through a controller, the head including nozzles, driving the head in response to the driving signal, and applying a first control signal that changes a driving waveform of the driving signal to the head through the controller.

Abstract: An apparatus for laser machining is provided including a stage for supporting a substrate and a controller for generating an error compensation table, a motor driver for moving the stage, and an error compensation unit for generating a table to compensate for an error. The error compensation unit includes a grid plate disposed on the stage and an imaging unit for imaging the grid plate. The motor driver outputs a position synchronization signal to the imaging unit according to a position of the stage. The imaging unit receives the position synchronization signal from the motor driver and images the grid plate while moving the stage.

Abstract: An apparatus includes a plurality of head portions which supplies droplets on a processing substrate, and a controller which applies a signal to each of the head portions, where the controller controls each of the head portions to supply the droplets on the processing substrate, where the signal includes a difference between a preset location of a pixel and an actual location of a pixel.
