Definitions

  • Multicolor plate printing machines are already known which comprise a printing cylinder on which sheets of paper to be printed are applied and a plate-holder cylinder. On the periphery of this cylinder are the inking roller or rollers that ink the plates.
  • the inking in the case of polychrome printing, is obtained by means of several inking rollers which each deposit ink--and thus a color--on a specific part of the plates.
  • the inking rollers assembly used for a given printing, therefore requires ink to be applied to the total surface of the plates.
  • the aim of the present invention is to avoid the above inconveniences and to provide an assisted inking device for a multicolor plate printing machine which enables a suitable inking of the plates and hence good quality prints.
  • Another object of the invention is to Wipe the surface of the plates without producing the slightest mixture of the various colors placed on the plate and in the engravings of this plate.
  • Another object of the invention is to compact the ink into the bottom of the grooves to regulate the quantity of ink found in these engravings so as to prevent the ink from spreading out during printing.
  • Another object of the invention is to clean the regulating roller applied to the inked plate so as to prevent a mixture of inks on the regulating roller and thus avoid traces of mixed inks which might appear on this regulating roller and so be carried on the inked plate.
  • FIGURE 1 shows in a diagrammatic manner, a multicolor plate printing machine according to the invention
  • FIGURES 2, 3, 4 and 5 show modifications of inking plates as wiping progresses.
  • the machine consists of a printing cylinder 1 on whch several sectors are arranged for receiving sheets to be printed.
  • the printing cylinder 1 thus comprises two sectors 2 diametrically opposed receiving the sheets to be printed.
  • This printing cylinder is in contact by its periphery with the plate-holder cylinder 3 comprising two intaglio plates or dies 4.
  • the position of the plate-holder cylinder 3 is determined in relation to the printing cylinder 1 so that the plates 4 come into exact correspondence with the sheets to be printed placed on the sectors 2 during the rotation of the cylinders 1 and 3.
  • two sets of rollers are applied, the first of these sets comprising the rollers 6, 7, 8 and 9 intended for inking the plates, each for one color of ink, the second set comprising the rollers 10, 11 and 12 are more particularly intended to remove the surplus ink from the engravings and on the surface of the plates without mixing the colors and to perfectly wipe said surface.
  • This inking is, for example, obtained for each of the rollers, 6, 7, 8 and 9 by means of secondary rollers 6 6 6 6 and 6 of which one 6 is in contact with an ink fountain 6 Some of the rollers have an axial movement.
  • this inking is not yet suitable for printing, for, on the one hand, the surface of the plate 4 is covered With ink, and on the other, the ink is not placed into the bottom of the grooves 14 of the plate.
  • the set of rollers 10, 11 and 12 is therefore intended to compact the ink in the bottom of the grooves, to remove the ink from the surface of the plate, and to adjust the quantity of ink deposited in the grooves: to a necessary optimum volume.
  • roller 10 On the periphery of the plate-holder cylinder 3 and after the inking rollers, in the rotation direction of this plate-holder cylinder 3, there is first of all provided a roller 10, which is intended to compact the ink in the bottom of the grooves and to remove a part of the ink from the grooves and from the surface of the plate without mixing the colors.
  • the roller 10 revolves at a circumferential speed which is the same as that of the plateholder cylinder 3 and its diameter is furthermore so designed as to take into account the sinking in pressure in such a way that the length of its circumference strictly corresponds to the length of the plates 4, so that during the rotation of this roller 10 in relation to the plate-holder cylinder, each generatrix of the roller 10 always comes into contact with the same generatrix of the plate-holder cylinder.
  • the last roller 17 of the cleaning rollers is, moreover,
  • roller 10 Following the roller 10 there is a prewiping roller 11 which revolves in the same direction as this roller 10, but at a slightly higher rotation speed than that of the plateholder cylinder 3. There is thus produced a slight slipping of the periphery of this roller against the plates 4.
  • this roller is calculated so as to prevent any mixture of colors on the surface of the plates, which is, furthermore, facilitated by the fact that the ink on the surface of the plates 4 has already been partially removed by the roller 10.
  • This roller 11 can also and eventually be accomplished by a lateral reciprocating movement having the object of increasing the wiping action, on condition that only one color is printed.
  • This roller 11 combined with the action of the roller 10, is intended to assist in the wiping of the upper surface of the plates '4, and to remove a certain additional quantity of ink from the grooves 14 (see FIGURE 4), in order to bring it to the required volume and thus prevent the spreading of the ink which would not fail to occur under the action of the paper, which, because of the printing pressure, penetrates more or less deeply into the grooves, accordinging to its nature and the characteristics of the packing material of the printing cylinder 1.
  • the roller 12 revolves in the opposite direction as the cylinder 3 and is applied so as to produce considerable friction on the upper surface of the plates.
  • the cleaning of the rollers 11 and 12 is obtained as in the case of the cleaning roller 17 by brushes 19 and doctor blades 18.
  • the printing machine may be a sheet fed machine or web machine fed from reels.
  • An inking device for a multi-color plate printing machine comprising a printing cylinder, a plate-holder cylinder equipped with at least one engraved intaglio plate adapted to be consecutively inked with several inks of different color, a plurality of inking rollers in contact with said plate-holder cylinder, at first compacting roller located in sequence after said inking rollers in engagement without slippage with said plate-holder cylinder, for compacting the ink into the bottom of grooves engraved in said plate and for removing a portion of ink from said grooves as well as a portion from the upper face of said plates without mixing the colors, said first compacting roller having a diameter arranged so that each generatrix thereof always comes in contact with the same generatrix of said plate-holder cylinder, a second roller located in sequence after said first roller in the same rotational direction as said plate-holder cylinder and revolving in the same rotational direction as said first roller at a very slightly higher circumferential speed than that of said plate-holder cylinder for removing surplus ink from
  • An inking device for a multi-color plate printing machine as set forth in claim 1 wherein said means for cleaning said first roller includes a fourth roller in contact with said first roller, and a fifth roller in contact with said fourth roller for removing the ink from said first roller, each of said first, fourth and fifth rollers revolving on each other without slippage.
