Title: Registering control apparatus for multicolor printing press
Inventor: MASUDA TOSHIAKI
IPC: B41F33/04
Filed: 1986-09-12
Abstract: PURPOSE:To control the color registering in a multicolor printing press with high accuracy, by mounting a means for inputting a crisscross register mark as image data, a means for calculating the registering shift quantity between colors from the crisscross register mark and a means for performing the adjustment of registering corresponding to the registering shift quantity being calculated. CONSTITUTION:When a positional shift is generated in crisscross register marks 65-68, registering inferiority is considered to be generated. By emphasizing the gradation difference of black, blue, red and yellow by using a monochromatic sensor in a line camera and utilizing a color correction filter, the signal levels of image signals of black, blue, red and yellow are adjusted so that a white paper part becomes a value of about 200, a black part becomes a value of about 20, a blue part becomes a value of about 75, a red part becomes a value of about 110 and a yellow part becomes a value of about 150 and stored in buffers at every picture element. At first, the data of one line is read from one buffer and the change point of a signal level is detected at every pixel, and the number of times of falling, the signal level of the first falling pixel and the number of a falling pixel are stored. When registering shift is generated, the numbers of two falling pixels being stored are read and the operation is applied to calculate registering correcting quantity. Next, a correcting direction moving a plate cylinder is specified from the first falling signal level.

Filed: 1989-08-23
Abstract: PURPOSE:To suppress the change in display colors and to make stable display by constituting the element so as to allow the selective transmission of light of a green wavelength and mixing a yellow dichromatic dyestuff with a liquid crystal. CONSTITUTION:Colors change from green to blue in a clockwise direction with an increase in driving voltage in an L*a*b* color specification system. Color is determined by three elements; lightness L*, hue H* and saturation C*; the hue H<0> is expressed by a central angle and the saturation C* by the length of segments. The value of the hue H<0> increases with an increase in the driving voltage and enters a 3rd quadrant from a 2nd quadrant in the case of making of green display. The yellow dichromatic dyestuff is, thereupon, previously mixed in the liquid crystal, by which the increase of the value of the hue H<0> to enter the 3rd quadrant is prevented.
