    Abstract: A printing plate (50) is provided with a plurality of positioning holes (50d) at the head portion (50a) on the basis of at least two cross sides (51a, 51b) of the printing plate (50). The printing plate (50) is delivered towards the plate cylinder (3) by the predetermined distance on the basis of two cross sides (51a, 51b) in relation to the rotation of the plate cylinder (3) so that each positioning holes (50d) can be engaged with the corresponding positioning pins (315) of the plate cylinder (3). This allows the printing plate (50) to be automatically and accurately mounted onto the designated position of the plate cylinder (3).

    Abstract: An ultraviolet ray measuring, apparatus is provided which comprises first and second photodiodes having substantially the same spectral sensitivity at least in an ultraviolet band, and a first optical filter arranged in front of a light-receiving face of the second photodiode, for shielding only light of at least a part of the ultraviolet band , and measures the light intensity and its accumulated value in accordance with the difference between electric signals output from the first and second photodiodes. It is preferable that a second optical filter, which has a main transmitting band in the ultraviolet band and a sub-transmitting band in the visible light range, be arranged in front of the light-receiving faces of the first and second photodiode. A multi-step bar graph display device displays indexes, such as an MED multiple value and an SPF value, which represent the measured light intensity and accumulated value in association with a reference MEL) value, so that this apparatus can suitably serve as a sunburn monitor.

    Abstract: A multicolor printing press incorporating a plurality of plate cylinders (3,4) capable of winding dampening-waterless plates (50) onto themselves at the predetermined positions of the printing press body (1). The multicolor printing press is provided with a plurality of inking devices (7, 8) and plate feeding/discharging devices (5, 6) which are commonly made available for these plate cylinders (3, 4) so that these devices can individually be mounted onto and removed from the positions of printing press body (1) oposite the plate cylinders (3, 4), thus allowing the printing plate (50) to be automatically fed to and discharged from the plate cylinders (3,4) and the printing operation to be quickly and easily changed as required.
