摘要：PURPOSE: To reduce an erroneous regulation and to easily handle by sending a light having light waves of two types capable of being visually identified by a light emitting means, and switching to a first wavelength for displaying an ink amount and to a second wavelength for displaying a dampening water amount. CONSTITUTION: A controller 1 has a light pen 7, and a plurality of columns 8 made of several dichroic LEDs 9 disposed in one row so that number of the columns 8 corresponds to numbers of zones of an adjustable ink and dampening water equivalently arranged in an entire width of a printed image, and the ink amount and the water amount according to the zones are displayed by red and green colors. For example, to adjust the water amount, when an ink/dampening water select switch 16 is set to a second position, two boards 17, 19 are excited by a logic calculator in the controller 1. The red light board 17 is excited during a time tLG and the pen 7 senses it, but cannot be seen with naked eyes. During next times tFAG and tGAZ, green light board 19 is excited to be visually sensed to roughly display an adjusted value. Accordingly, the pen 7 may sense only dichroic or monochromatic color.
