  • the ink furnishing devices should be of the same form.
  • the constitution of the ink furnishing means can be changed by the color of ink or by the position of installation on the rotary printing machine.
  • the ratio of mixing or/and size of the minute hollow bodies 12 used on the inking roller 1 is usually changed with a consideration given to the fluidity of ink and the relation between the ink film thickness and reflective color richness (hereinafter called color richness by film thickness). Only the size of the minute hollow body 12 or only the ratio of mixing of the minute hollow body 12 or both the size and ratio of mixing of the minute hollow bodies can be changed. In most cases the fluidity and color richness by film thickness of ink are different by ink. With the ink of a low fluidity with difficulty in flowing as far as fluidity is concerned, the ratio of mixing of minute hollow bodies 12 has to be increased or/and the size of the minute hollow body 12 has to be made larger.
  • the fluidity of ink is, however, different with the ink according to the measurement by the applicant of the invention which shows that the fluidity (glass palte, 10 minutes, temperature 25°C, flow extension mm) of yellow was 194, that of magenda 256, that of cyanide 246, and that of black 29s.

If a number of inks of different colors are used for printing, the print should have a balance in the richnesses of color by film thickness for the colors on the print, and in order to achieve the balance, the thickness of film should be defferent by the ink, that is, the quantity of furnished ink should be varied. This means that the volumes of minute cells, etc. should be different.
  • the ink for printing is a mixture of a pigment and liquid.
  • the fluidity and richness of color by film thickness change independently by the difference in the pigment or liquid or/and the difference in the ratios of their mixing. It is, therefore, necessary to select an inking roller to be used for each ink.
  • a multicolor rotary printing machine which is capable of furnishing a proper quantity of ink according to its physical property and method of multicolor printing which is used in the multicolor printing machine of the invention can be provided.
  • the ink furnishing device used in multicolor rotary printing machines of present invention can be effectively used for multicolor rotary printing machines of satellite type, B-B stacking type, B-B laterally arranged type or other types.
  • the inking roller with which an ink removal member is in contact and to which the ink removal member works wears, the outer circumferential surface of the inking roller develops no significant change and the inking roller can be used for a long term, making the frequency of replacing the inking roller small and raising the efficiency of the printing work. Furthermore, when the powder of a hard material is dispersed and mixed in the ink receiving layer, the powder which is exposed on the surface of the receiving layer carries the load from a doctor blade so that the wear in the ink receiving layer is suppressed to give a longer life of the inking roller.
  • the inking roller is less expensive than the anilox roller which is conventionally used and the frequency of replacing the inking roller is less, the running cost of multicolor rotary printing machines according to the present invention is much reduced.
