Abstract

PURPOSE:To make it possible to determine a necessary ink amount efficiently, in a printing apparatus for supplying an ink in accordance with the image element ratio of black and white in a printing image, by obtaining said ratio by sampling and extracting the image data of image memory. CONSTITUTION:The part of original data contained in a disc D is taken into buffer memory B and plural sets of data are extracted in a unit amount and contained in a register R while a number of black dots are calibrated by a counter K to be inputted in an adder A and this operation is carried out predetermined times to store calibrated value by external memory M. When rotary press printing is carried out, a number of black dots of the column stored by the external memory M is put in a rotary press control apparatus S and ink amount regulating valves I1-In are controlled corresponding to a number of black dots to adjust the supply amount of an ink in proper quantities. Therefore, an optimum amount of an ink can be supplied by a simple apparatus.

とする印刷方式を提供することにより達成される。It is an object of the present invention to provide a printing method that efficiently discharges the amount of ink required for printing in one go. For each divided area of the printing area, the ink of FC Hashi is supplied from the ink tank according to the ratio of printing 1 Ao's Shima Yuki and Shiro. The ratio is obtained by extracting the own data, and the ratio is stored in a storage unit, and the output of the storage unit is outputted to control the amount of ink supplied from the ink tank to the printing area of the spinning printing rotary press. thing**
This is achieved by providing a printing method that does this.
