Title:
活性化可能でないレーザダイオードも有しているレーザダイオード集合体による版の画像付け
Document Type and Number:
Japanese Patent JP4246527
Kind Code:
B2
Abstract:
The method involves increasing a relative speed between an imaging device and a printing form by a real factor. An exposure time per printing dot is shortened by another factor that is reciprocal to the former factor. The printing form is imaged using activatable laser diodes (16) for inputting an amount of energy per printing dot on the form with an imaging intensity that is a function of exposure time. The relative speed is increased by a factor f, where f is greater than 1 and f is at most n and f is a real number and n is the number of laser diodes. The exposure time is shortened by the factor 1dividef. Independent claims are also included for the following: (a) an imaging device for a printing form (b) a printing press.
