1. A method of performing screen printing on a substrate used for the manufacture of a solar cell, comprising:
moving a print head over a screen by a first drive actuator to perform a printing stroke in a first direction; and
moving a material processing head in the first direction by a second drive actuator to perform a material processing stroke behind the print head,
the print head being moved away from the material processing head by the first drive actuator during a distance increasing phase of the printing stroke to increase a separation distance between the print head and the material processing head, an average stroke speed of the material processing head during the material processing stroke being higher than an average stroke speed of the print head during the printing stroke so that a duration of the material processing stroke is shorter than a duration of the printing stroke.
