Definitions

  • the present invention relates to printing of bar codes. More particularly, the present invention relates to an apparatus and process for sequential printing of solid areas or lines of different widths on continuous webs of absorbent material, such as paper, which may be in roll form or in collated pack, folded form.
  • bar codes for identifying data and/or information is increasing in volume and in various applications throughout the media industry.
  • Printing of the bar codes can be accomplished using standard letterpress inks which are formulated to remain "open” (undried or not set) in the ink train and to be machine processed with minimum, if any, solvents or like drying agents. The result is that such inks remain "open” after being applied to paper or like record media.
  • inks remain "open” after being applied to paper or like record media.
  • an apparatus for printing bar codes on a continuous web of absorbent material characterized by printing means including a supply of ultraviolet- curable ink; transport means for continuously moving said web past said printing means; driving means for operating said printing means for sequentially printing bar code arrays on said web during advancement thereof; and drying means for drying the printed bar code arrays with ultraviolet radiation immediately after the printing operation.
  • a process for printing bar codes on continuous web of absorbent material characterized by the steps of providing printing means containing a supply of ultraviolet-curable ink, advancing the substrate along a path past the printing means, driving the printing means for sequential printing of bar code arrays on said web during advancement thereof, and drying the printed bar code arrays with ultraviolet radiation immediately after the printing operation.
  • the ultraviolet-curable ink is letterpress black and is especially suitable for use in printing bar codes to ensure complete bar or area printing with minimum voids in the printed format.
  • the use of the ultraviolet radiation drying apparatus provides for rapid drying of the ink to enable rewinding of the continuous form or the repacking or refolding of the forms immediately after printing without extraneous ink offsetting to non-print areas of the form.
  • Fig. 1 is a side elevational view in diagrammatic form of a printing apparatus according to the invention for roll media;
  • Fig. 2 is a similar view of another embodiment of the printing apparatus according to the invention for pack or folded media;

  • the web 36 then passes into and through an ultraviolet radiation dryer 62 which provides for rapid drying of the ultraviolet-curable ink that is used to print and form the bar code arrays in sequential printing manner.
  • the web 36 turns the corner around and past a pull roller or like member 64 which may be journaled on a suitably supported shaft 66.
  • a cooperating pressure or guide roll 68 (also called an over roll) journaled on a shaft 70 is positioned above the pull roller 64 to provide a passageway for the web 36.
  • the supply roll 38 and the rewind roll 42 may be supported for rotation in the cradles 41 and 45, respectively, or by other suitable means.
  • Fig. 2 illustrates another arrangement of apparatus, generally indicated as 80, and utilizing some of the same structure and members of the apparatus, as shown in Fig. 1.
  • the drive motor 32 and apparatus control means 34 may be similar in function, but different in operation from the arrangement of Fig. 1, such control means 34 including a programmable variable length draw in the direction of movement of the web 82.
  • the web 82 in Fig. 2 is formed in a collated pack or folded configuration, as shown in the pack or stack 84 at the left side of the apparatus 80, and unfolds upwardly and around the corner member 46 and along the table 50.
  • the web 82 continues along the table 50 and under an printing or numbering unit 86 which is supported in suitable manner for reciprocating motion in the indicated up-and-down direction.
  • the reciprocating numbering unit 86 prints a column of bars across the width of the web 82 by means of printing elements 88 spaced across the width of the numbering unit 86, and prints successive columns of bars as such web 82 continues along the table 50.
  • a reservoir or container 89 of ultraviolet-curable ink may be provided in the unit 86 to supply ink to the printing elements 88.
  • a fixed position platen member 90 is provided under the printing elements 88 of the numbering unit 86 and opposed thereto for impacting thereagainst by the printing elements in the printing operation.
  • the web 82 then passes into and through the ultraviolet dryer 62 which provides for rapid drying of the ultraviolet-curable ink that is used to print and form the bar code arrays in sequential printing manner.
  • the web 82 then turns the corner around a sprocketed pin pull roller 64 and the web is then delivered in refolded manner in a receding stacker 92 (movable in the direction as indicated by the arrow) at the right side of the apparatus 80.

  • the McAdams VC 100 machine readily accommodates a web (36 or 82) width of 40 centimeters.
  • the reciprocating unit 86 prints ten complete bar code arrays in a web length of 20 centimeters.
  • the wheel assembly 52 (Fig. 1), having a circumference of 56 centimeters and carrying four print elements 56, prints a complete bar code array at 14 centimeters spacings, in one embodiment of the invention.
  • the spacing of the printed bar code arrays is different for wheels that are provided and spaced for two or three print elements 56 around the circumference.
  • the Fig. 2 arrangement is preferred by reason of the compact spacing and the improved quality of the bar code printing.
