Definitions

  • the present invention relates to electronic printing systems and, more particularly, to the architecture of high speed web presses for electronic printing.
  • Electronic printing includes all ink jet printing, such as continuous ink jet printing, and all other systems wherein images are dried to fix the image on the substrate, as well as ionography, electrophotography, and all other systems wherein toner is fused to fix the image on the substrate.
  • Current large scale electronic printing presses typified by the Scitex 3500/3600 family, manufactured by Scitex Digital Printing, Inc., of Dayton, Ohio, are configured with a standard fuser/fixer or fixer/dryer system and are capable of drying at high speed, and full width.
  • the design of a typical fixer/dryer is very much related to the designs of fixers in general use in the printing industry.
  • dryers are purchased as standard configurations, which are available with few options. They can be used at lower power if they are to be used at low speed, but standard products are generally not modular in the sense to be described below.
  • Conventional printing presses arrange all the apparatus for printing in a tower. Paper is fed to the tower by appropriate paper feeding apparatus using either sheets of paper, or a continuous web of paper. Typical color printing presses utilize multiple “towers". The paper is fed sequentially from one tower to the next, each tower printing a particular color (or sometimes a transparent coating). For printing processes which require fixing of one color ink before the next color ink is printed, a standard fixer/dryer is used between towers.
  • Another common web configuration is called a "perfecting" press.
  • print stations are positioned on each side of the web, so that both sides of the substrate are printed essentially simultaneously. This helps the floor space requirements, but the press setup is complicated by the dense packing of the equipment.
  • GB-A-2159770 disclosed a thermal element print unit comprising a print head embodying a plurality of heat elements arranged in linear formation and adapted to be selectively energised, means for feeding a web of thermo-reactive paper past the print head, an electrical connection for the print head and a series of control circuits for controlling the selective energisation of the print heads wherein the print heads are mounted in a pivoted cover so that the thermal elements may be readily moved away from the web of paper for cleaning and other purposes.
  • the present invention provides modular ink jet printer architecture wherein printers are allowed to be constructed from modules which can be upgraded for increased number of colors, increased capability in speed, simplex/duplex and print width, and which enables compact, cost effective systems.
  • an electronic printing system comprising:
  • the substrate is controllably transported through the printing system past a plurality of print stations in sequence.
  • Each of the print stations are capable of printing on one side of the substrate.
  • a preferred system further comprises means for fixing the printed image between image stations without contacting the printed side until it is dry, and means for collecting the completed print work by rewinding the work on a roll, cutting the work into pages and stacking it, or any other suitable finishing operations.
  • Print heads are mounted on a swing arm mechanism to allow rotation from a print-ready position into a service position.
  • the system is created from simplex print modules and is capable of multi-color duplex printing without turnbars between print stations or print modules.
  • the system is configured so that additional print stations can be added to the printing system without adding substantially to the length of the system.
  • the present invention can improve the architecture of an electronic printer so that modular solutions to various printing problems can be obtained. Further the present invention can provide a duplex color printing system which does not grow in length as more printing colors are required.
  • the present invention can provide a modular system which can be field upgraded from one color to multiple colors, and from simplex to duplex printing without adding proportional length to the printing system.
  • the invention can enable a modular upgrade path from page wide printing to two-up printing.
  • This invention can provide an architecture in which the fixer/dryer is in a position separated from, and specifically not under, the electronic printing system. This has the advantage of insuring that the electronic print system is not affected by heat from the fixer/dryer.
  • This invention can enable modular growth in drying capability as process speed increases. This provides the advantage of consolidating the dryers into a single modular unit to lower cost and enable improved management of the heat.
  • the present invention can provide the further advantage of enabling use of a single exhaust for air flow and a single insulated cabinet.
  • a paper path for a proposed printer architecture 10 is illustrated in Fig. 1.
  • the paper input and output features applicable to this invention are readily available standard components. The available options for paper input and output are quite broad.
  • the illustration depicts a system which uses a roll feed input and a sheeter/stacker output 11. Paper proceeds generally from the left to the right in the press illustrated. Paper from the roll proceeds through the region where duplex printing and drying are accomplished. The details of the print head fixer/dryer region vary, depending on the desired capability of the particular press.
  • a print engine comprises two towers 14, 16 of print modules 12 with a fixer/dryer region 20 situated between the towers 14 and 16.
  • a print module 12 typically comprises adjustable print head mounts, rollers, and cue sensors.
  • print heads 18 are accessible to the system operator.
  • the print head mounts in the print module 12 could be rotated 90° about a vertical axis pivot on one side of the module 12, to provide the system operator print head access.
  • the arrangement according to the present invention enables multi-color duplex printing in a very compact architecture, without requiring turnbars between print stations.
  • finishing comprises various tasks, including but not limited to collecting the completed print work by rewinding it on a roll, cutting it into sheets or pages, stacking, folding, collating, etc.
  • Fig. 2 there is illustrated a side view of an embodiment of an electronic print station having eight print modules 12.
  • the print engine of Fig. 2 is comprised of eight print modules 12, it will be obvious to those skilled in the art that the number and arrangement of print modules may vary without departing from the scope of the present invention.
  • the right hand stack of print modules is not needed if only one side of the substrate is being printed.
  • the print stations comprise ink jet print stations in an ink jet system.
  • the ink jet system may comprise a continuous ink jet system or a drop-on-demand ink jet system.
  • the system could further comprise a continuous binary ink jet system having either a variable or a fixed number of drops per spot printed.
  • the number of pixels per inch is preferably at least eighty.
  • the maximum number of drops printed per spot is typically between one and sixty-four.
  • the ink jet system comprises a duplex full process color printing system. Although the process speed is typically at least fifty feet per minute, the speed could be slower, such as for a drop-on-demand system.
  • Fig. 3 is an illustration of two print modules 12 printing on opposite sides of substrate 22.
  • the substrate 22 enters from the top left of Fig. 3, as indicated by arrow 30, and is wrapped around rollers 32 which provide a positive wrap around roller 34.
  • the positive wrap provides a fixed position for printing.
  • an eighteen inch print swath is to be created with the use of two nine inch print heads.
  • This approach provides modularity in width. If the required print width is only, for example, nine inches, only one print head is required at each print station.
  • the print head over roller 34 is spatially closer to the viewer than the print head over roller 36, which is further from the viewer. Print heads which are physically wider than their print swaths are staggered so that their print swaths butt (stitch), allowing the desired eighteen inch total print swath.
  • roller 38 touches the opposite side of the web from the unfixed image.
  • the bottom, or print side, of the web is heated, and the image is fixed.
  • the web now proceeds to rollers 42 and 44, where an image is placed on the opposite side of the web from the image placed at the earlier print stations at rollers 34 and 36. The result is a duplex image created without a turnbar.
  • the web now passes through the dryer area 20 again, and the unfixed image on the bottom of the web is fixed.
  • FIG. 3 there is right side module 12 comprising two print heads 18 over rollers 34 and 36.
  • the right side module 12 is identical to or the mirror image of left side module 12, comprising two print heads 18 over rollers 42 and 44.
  • the dryers 40 are the same as dryers 50.
  • the dryers 40 and 50 are themselves modular. The means for drying is positioned so that heat from the dryer does not affect print mechanisms. In the configuration illustrated, there are two dryers.
  • the lower throughput device could use one module in its dryer, while the higher throughput device could use two modules, side by side.
  • the dryers could be modular in width, so that, for example, a nine inch print width could use a single dryer, while the comparable eighteen inch print width would use two dryer modules, each drying half the print width.
  • FIG. 3 Another level of modularity comprises the entire single color print system illustrated in Fig. 3. This system occurs at four positions in Fig. 2, to make up a four color duplex printer. In that context, it should be observed in Fig. 3 that the web enters the dryer area at the top left at the same angle as the web exits at the lower right.
  • print modules such as printing two colors on a front side of the substrate and one color on a back side, or three colors on a front side and two on a back side, or one color on a front side and three colors on a back side, etc.
  • a further feature of the print system illustrated in Fig. 3 is that opposite pairs of print heads 18 are at the same vertical height. This enables simpler maintenance and also allows for a stackable module. If a fifth print station is required for a particular system, it can be added to the system in a straightforward manner, without lengthening the digital printer. It is also possible, with the present invention, to add a second tower to provide fifth and/or sixth color capability, although this, of course, would lengthen the system.
  • Fig. 4 there is illustrated a top view of the mounting of the print heads 18, showing how multiple print heads, specifically two print heads, are used to cover the total printed width.
  • print heads 18 are accessible to the system operator.
  • the print head mounts in the print module 12 can be rotated by 90° about vertical axis pivot points 51 and 53 on one side of the module 12, to provide the system operator print head access.
  • the print head which prints on the left side of the web is placed over roller 36, and is attached to swing arm 50.
  • the right side of swing arm 50 is detachably fixed to a stop 55, typically located on the right side of the printing system.
  • swing arm 50 In the detached position, swing arm 50 assumes a position 50a at which the print head is serviceable by an operator. Similarly, swing arm 52 can swing about the pivot point 53 to assume the position 52a illustrated. This enables print head service by approaching the print head from the perspective 58.
  • 55 illustrates an exploded view of the attachment point of either swing arm 50 or 52.
  • a knurled screw 60 is shown as the means of attachment, but it is clear to one skilled in the art, that other quick detachment means could be used.
  • the attachment means attaches the bar 50 (or 52) to a stop 54 which is slidably attached to a member 56 which is fixed to the frame of the electronic printing system. Movement of the stop 54 relative to the fixed member 56 by suitable adjusting means (not shown) creates a small change in the angle of the swing arm 50 (or 52).
  • the system which mounts the print head 18 to the swing arm also allows significant adjustment in the "y" axis illustrated in Fig. 4 so that the print swaths of the print heads on rollers 34 and 36 can be perfectly aligned with one another.
  • the mounting means also allows some degree of motion in the "x" direction, so that the print heads can be positioned properly with relation to the rollers 34 and 36. This latter adjustment is especially important because adjustment of the swing arm attachment point 54 also causes some motion of the print head in the "x" direction as a result of the alignment of the print head and roller axes.
  • the entire print system comprising module 12, fixer/dryer region 20, and tower 16, can optionally be rotated 90° by means of one turnbar at the top of unit 20 and one turnbar at the bottom of unit 20.
  • the print modules 12 can face aisles on either side of the web flow, enabling viewing and print head access, as well as shortening the length of the overall system.
  • the present invention is useful in the field of electronic printing, and has the advantages of improving the architecture of an electronic printer so that modular solutions to various printing problems can be obtained. It is another advantage of the present invention that it provides a duplex color printing system which does not grow in length as more printing colors are required. It is a further advantage of the present invention that the modular system can be field upgraded from one color to multiple colors, and from simplex to duplex printing without adding proportional length to the printing system. It is a further advantage of the invention that it enables a modular upgrade path from page wide printing to two-up printing. It is another advantage of this invention that it provides an architecture which positions the fixer/dryers such that they are consolidated in a single cabinet and separated from, and specifically not under, the electronic printing system.
