Definitions

  • This invention relates to printing apparatus and has to do with means for obviating smearing and transfer of ink when in the passage of sheets through a printing press the printing on the sheets is contacted by a surface of an element of the press before the ink is completely dry.
  • An example of printing apparatus to which my invention is applicable is a perfecting press in which sheets are printed on opposite sides in separating printing couples, the sheets being advanced through the press from the first printing couple to the second printing couple.
  • the time which elapses between the printing on one side of a sheet in the first printing couple and the printing on the opposite side of the sheet in the second printing couple is very short so that even with the use of quick drying ink the ink constituting the printing of the first printing couple is not completely dry when the sheet reaches the second printing couple.
  • the impression cylinder has been covered with an aluminum sheet which has been grained or anodized or sand-blasted or otherwise treated but that did notobviate smearing and ink transfer.
  • the impression cylinder has been covered with a sheet consisting of a paper backing covering with an adhesive in which minute glass beads or spheres are embedded but completely satisfactory results have not been obtained.
  • a chromiumsurfaced element for contact with the not completely dry ink constituting the printing of the first printing couple as the sheet is advanced to and through the second printing couple.
  • the impression cylinder of the second printing couple may have a chromium surface; also, a transfer cylinder between the printing couples inay be provided with a chromium surface.
  • transfer cylinders have been employed consisting of parallel partial disc-like elements positioned to engage the side of sheets which has been printed on but on which the ink is not completely dry, such elements contacting the sheets at spaces or gaps in the printing, as, for example, page borders in a sheet on which several pages are printed at the same time.
  • a chromiumsurfaced sheet can be disposed at the periphery of the partial disc-like elements of sucha transfer cylinder so as to span the spaces between such elements with the chromium surface of the sheet disposed outwardly.
  • the chromium surface should have a roughness of at least microinches (R.M.S.) but not to exceed 300 microinches (R.M.S.). I find that an ideal chromium surface is produced by chromium plating. A very thin plating of chromium serves the purpose, al-
  • the plating may be of any thickness. Excellent results are obtained with a chromium plating having a thickness in the range .0003"-.0005".
  • the impression cylinder of the second printing couple may not have the chromium-plated sheet applied to it but such sheet may be applied when the press is used for perfecting.
  • Application of the sheet increases the effective diameter of the impression cylinder which in turn affects the printing. Consequently it i desirable that the sheet be of minimum thickness consistent with obtaining of the results sought. sheet in place on the impression cylinder for two-color printing or to replace it with a plain sheet of equal thickness so that the effective diameter of the impression cylinder of the second printing couple will be the same in straight two-color printing as in perfecting.
  • FlGURE 1 is a diagram of an oifset printing press which may be used selectively for straight two-color printing or for perfecting, such press being of the type disclosed in said Patent No. 2,757,610;
  • FIGURE 2 is a cross-sectional view through the impression cylinder of the second printing couple
  • FIGURE 3 is a cross-sectional view through the first transfer cylinder.
  • FIGURE 4 is a fragmentary View taken at right angles to the axis of the transfer cylinder of FIGURE 3 showing one of the parallel partial disc-like elements of the transfer cylinder before the chromium-surfaced sheet is appiied to the transfer cylinder.
  • the press shown in FIGURE 1 has a first plate cylinder 2 to which the first printing plate is applied and to which ink and Water are applied by means not shown well known to those skilled in the art.
  • the first blanket cylinder is designated 3. It offsets the ink from the first plate cylinder 2 onto the first side of sheets fed to the press on a feed board 4.
  • the sheets are taken by grippers of the first impression cylinder 5 and are printed upon by the first blanket cylinder 3 as they pass between the first blanket cylinder 3 and the first impression cylinder 5 constituting the first printing couple.
  • the sheets are taken from the first impression cylinder 5 by grippers on the first transfer cylinder 6 and are delivered to grippers on the second transfer cylinder 7. From the second transfer cylinder 7 the sheets are delivered to grippers of the third transfer cylinder 8 whence they are delivered to grippers of the second impression cylinder 9 coacting with the second blanket cylinder 10 to form the second printing couple.
  • the second blanket cylinder 10 offsets ink from the second plate cylinder 11 which carries the second printing plate to which ink and water are applied by means not shown well known to those skilled in the art.
  • the grippers of the various cylinders are not shown in FIGURE 1 as their structure and function are well known to those skilled in the art; moreover, the grippers are shown in Patent No. 2,757,610.
  • the third transfer cy inder 8 may take the sheets from the second transfer cylinder 7 by either their leading edges or their trailing edges depending upon whether the press is being used for straight two-color printing or for perfecting. When the press is being used for straight two-color printing the grippers of the third transfer cylinder 8 take the sheets from the second transfer cylinder 7 by their leading edges with the result that the second printing couple prints upon the same side of the sheets as the first printing couple.
  • FIGURE 1 The direction of rotation of the cylinder is indicated in FIGURE 1 by arrows.
  • the second impression cylinder 9 is shown in FIGURE 2. It includes grippers 12 coacting with a gripper pad 13 and operated in well known manner. Since the operation of the grippers is not involved in the present invention such operation will not be described but will be understood by those skilled in the art.
  • a sheet 14 is applied to the surface of the cylinder 9, the ends 15 and 16 of the sheet being held by suitable clamping means.
  • the sheet 14 is a chromium-plated aluminum sheet with the chromiurn-plated surface disposed outwardly.
  • the aluminum sheet per se is .009" thick and the chromium plating has a flash thickness of .0004 making the total thickness of the chromium-plated sheet .0094".
  • the outer or chromium-plated surface of the sheet 14 has a roughness of 190 microinches (R.M.S.).
  • sheets which have been printed in the first printing couple are delivered to the second printing couple they are taken by the grippers 12 of the second impression cylinder 9 with the side of the sheet which was printed in the first printing couple disposed against the outer chromium-plated face of the sheet 14 which is resistant to the not completely dry ink and obviates smearing of the ink and transfer of ink to succeeding sheets.
  • the sheets are printed on the side opposite the side on which they were printed in the first printing couple and are taken from the second impression cylinder 9 by grippers of a delivery cylinder 17 whence they pass to a delivery mechanism as well known to those skilled in the art.
  • the sheet 14 When the press is used for straight two-color printing the sheet 14 may be left in place on the second impression cylinder 9 or it may be removed. By reason of its extreme thinness the sheet 14 does not materially alter the diameter of the cylinder 9, although of course it does alter such diameter to a slight extent. If desired the sheet 14 may be replaced by a plain sheet of the same thickness i as the sheet 14 when the press is used for straight two-color printing whereby the effective diameter of the cylinder 9 is precisely the same for straight two-color printing and for perfecting.
  • FIGURES 3 and 4 show the first transfer cylinder 6. That cylinder consists of parallel partial disc-like elements one of which is shown at 18 in FIGURE 4. When no sheet as presently to be described is applied to the first transfer cylinder the sheets passing thereabout are engaged by the elements 18 in unprinted areas. I apply to the cylinder 6 a sheet 19 which may be identical with the sheet 14 above described and applied to the cylinder 6 so that it is disposed at the periphery of the elements 18 and spanning the spaces therebetween. The sheet 15) may be fastened in place by any suitable fastening or clamping means indicated diagrammatically at 20.
  • the application of the sheet 19 transforms the first transfer cylinder 6 from a cylinder consisting of parallel partial disc-like elements adapted to engage the paper in unprinted areas into a cylinder having a continuous surface engaging the side of the sheet printed in the first printing couple.
  • the advantage is a more positive handling of the sheet while at the same time obviating smearing of the ink and transfer of ink to succeeding sheets.
  • a chromium-plated aluminum sheet used for the purpose above described receives a slight imprint of the printing but the imprint is negligible and the ink constituting the imprint dries in a single revolution so that it is not transferred to succeeding sheets. If desired, the sheet can be washed at intervals.
  • a printing press comprising a printing couple for printing on one side of a sheet and means for advancing the sheet after the sheet passes through said printing couple, said means including a surface against which the side of the sheet printed in said printing couple is adapted to lie before the ink is completely dry, said surface consisting of a thin layer of chromium having a roughness of at least microinches (R.M.S.) but not to exceed 300 microinches (R.M.S.) which is resistant to the ink whereby smearing of the ink and transfer of ink to succeeding sheets are obviated.
