  • PRINTING 2796 Variable Delay for Ink Jet Printer. 75 Inventor: Donald A. M n Lockpon [BM Tech. DlSCl. Bul1., V01. 11, NO. 12, May, 1969, NY pp. 1736-1737, Electrostatic Ink Deflection Bar Code Printer.” [73] Assignee: Moore Business Forms, Inc.,
  • variable alpha/numeric data is printed by a non impact printing system in registered and aligned relationship with fixed data printed by a master plate cylinder on a moving web at press speeds.
  • a programmed computer provides coded data representative of the variable data in a selected multiple line message format.
  • Character timing signals are generated in response to the coded data and command signals from the computer represent the sequential position of the alpha/numeric data in the multiple line message format.
  • the timing signals are automatically adjusted to accommodate different web speeds and variable form depths by an electrical top of form pulse occurring prior to the mechanical top of form of the master cylinder for each revolution thereof corrected by pulses, the rate of which is dependent on the speed of the web.
  • the variable alpha/numeric data is printed by using the character timing signals to independently control the projection of ink droplet streams from a plurality of ink jet nozzles onto the moving web.
  • variable message data can be imprinted on paper along with the printing of fixed data at press speeds.
  • the COMPURITE printing system disclosed herein represents a combining of business forms printing press equipment and computer outputs for the simultaneous printing of a form (or direct mail advertising piece) and the imprinting of variable data.
  • the variable data may be an address or other variable information available on the magnetic tape.
  • the COMPURITE system disclosed herein represents apparatus and method introducing a capability of printing at a maximum speed of 1,375 characters per second. At such speed variable information composed of 5 X 7 dot matrix characters may be printed on a web of paper moving at maximum press speeds.
  • the COM- PURITE apparatus disclosed herein is capable of being installed on printing presses without significantly reducing the efficiency of the existing production equipment.
  • the COMPURITE system provides significant advantages because of its modular characteristics which enhances its portability. it may be installed on multiprinter flexographic printing presses for producing a wide variety of products and sizes.
  • Flexography is a rotary, relief printing process employing fast drying, evaporating, solvent inks and usually flexible rubber printing plates. It is this ink distribution and transfer system made mandatory by such inks, the comparatively inexpensive printing plates, and the great advantage of quick and simple roller cleanup and press setup in changing from one job to the next, which sets flexography apart from the run-of-the-mill letterpress printing and makes it especially adaptable to high speed, low cost, in-line printing with converting machinery. Within reasonable limits, changes in size of the printing repeat can be accomplished economically and with insignificant waste. By mounting plates on printing cylinders of different circumferences and changing the spacing across the cylinders, size variations can be made in both the length and width. This interchangeability of plate cylinders (as well as their size) is the basic difference between flexography and conventional rotary letterpress. It allows the printer to make-ready off press while running other work; downtime is minimized.
  • FIG. 1 illustrates in block diagram form the basic components of the COMPURITE l ink jet printing system.
  • Variable data information to be printed by the ink jet nozzles in registration with fixed form data printed by a plate cylinder are stored in magnetic tape unit 30 on two magnetic tapes identified as unit 0 and unit 1.
  • the variable data is formatted so that the data therein can be read into, and under the control of, computer 31.
  • Computer 3] assembles the variable data into an alpha/numeric character message format for distribution to computer interface 33.
  • Computer 3] has the capability of reading the magnetic tapes, storing the data thereon and providing the basic data control and program sequencing functions for formulating the variable data input to computer interface 33.
  • Computer 31 includes the necessary input/output system and data bus lines for communication between computer interface 33 and CRT operator control and display 32.
  • CRT operator control and display 32 comprise at least a CRT display unit for visually displaying information to a system operator and an associated keyboard by which the operator may establish a dialog with the computer for the insertion of necessary data and information to establish various system parameters necessary for the operation of the COMPURITE I system.
  • the CRT display also provides the operator with information generated by the computer concerning the operation of the system.
  • Forms position and web speed 34 includes the necessary transducers, such as optical encoders, for providing data relating to the desired form depth, web speed, and rate of rotation of a master printing cylinder.
  • the web speed and rate of revolution of the master cylinder provide necessary timing pulse inputs to computer interface 33 so that the interface can provide the necessary timing and control signals for coordinating the operation of computer 31 and nozzle electronics 35 for printing the alpha/numeric characters in aligned and registered relationship on the moving web.
  • Computer interface 33 includes the necessary circuitry for receiving transducer signals from forms position and web speed 34, data control and sequencing information from computer 31, and status signals from nozzle electronics 35 and nozzles 36 to synchronize and aid in controlling the operation of the entire COM- PURITE l system.
  • Computer interface 33 essentially comprises five basic sub-components which respectively generate various control and synchronization signals for internal utilization within the interface itself and for the operation of the nozzle electronics. For reasons which will become more apparent with the subsequent discussion of the ink droplet formation and projection of the ink droplets in registered position on a moving web, the speed of which is variable as desired, it is necessary to control the time of ink droplet release as a function of web speed.
  • Computer interface 33 includes Top of Form Controller circuitry for precisely controlling the ink droplet release as a function of the web speed and the top of form of the master plate cylinder.
  • a corrected top of form pulse represents a basic control signal within the interface which is used as a reference from which all the character strobe and timing signals within the Interface are generated for the subsequent control of the nozzles within a print unit or print units.

  • Computer interface 33 includes a Master Head Controller for each print unit.
  • the Master Head Controller receives heading distance information from the computer and generates the necessary timing signals to control the ink droplet release from the first nozzle in each print unit with which the Master Head Controller is associated.

The operation of the Master Head Controller is controlled by the CTOF pulse.
  • the timing signals comprise character strobe pulses (STRl pulses) for providing a reference frame within which are formed five spaced character stroke strobe pulses (STRZ pulses) in which each of the STR2 pulses -times" the release of a respective column of the 5 X 7 matrix from which all of the alpha/numeric charac ters in the COMPURlTE 1 system are generted.
  • the Master Head Controller also generates additional timing signals which provide control functions to Head Controllers 2, 3, 4 and 5 of its associated print unit.
  • the Master Head Controller also generates a print request signal, prior to the actual time of droplet release, for the nozzle electronics so that the No. 1 nozzle of that printing unit can be primed for printing.
  • Computer interface 33 further includes common Head Controller circuitry for receiving a device address signal and control functions for operating the Master Head and Head Controllers 2, 3, 4 and 5 of a print unit.

  • the computer interface 33 further comprises identical circuitry for each of the second. third, fourth and fifth Head Controllers of each print unit to generate timing signals for controlling the respective droplet release from each of the associated nozzles 2, 3, 4 and 5 of that print unit.

  • STRl pulses character strobe pulses
  • STRZ pulses character strobe pulses
  • the character strobe and stroke strobe pulses from the respective Head Controllers 2, 3, 4 and 5 are generated to account for the displacement along the axis of web movement of the nozzle within a print unit. That displacement is fixed during any given printing operation, but may be varied within the mechanical limitations of the nozzle structure and the format which is desired to be printed.
  • each of Head Controllers 2, 3, 4 and 5 includes suitable circuitry for timing the generation of the character strobe and stroke strobe pulses to account for the spacing between the nozzles in the direction of web movement.
  • Each of the head controllers includes circuitry for generating a print request signal which is delivered to its associated nozzle to prime the associated nozzle for printing.
  • Head controller circuitry identical to all the head units is provided within computer interface 33 to count the number of characters printed by each nozzle so that end of message control signals can be generated to terminate the generation of the character strobe and stroke strobe pulses within the Master Head Controller and Head Controllers 2, 3, 4 and 5 of each of the print units as well as to signal the computer that the printing of a particular variable set of data has been completed.

  • the spacing of the lines between the printing nozzles of a given print unit and between the print units themselves, is variable and limited only by the mechanical configuration of the press, the mounting of the mechanical structure of the print units, etc.
  • Nozzle electronics 35 receives the coded alpha/numeric character data output as well as the character STRl and STRZ pulses of computer interface 33, whereby the printing of the alpha/numeric characters from each of the nozzles within a print unit is controlled.
  • a matrix generator for each of the nozzles provides a stream of pulses synchronized with respect to the generation of ink droplets in the nozzles themselves. The pulse stream is timed by the character strobe pulses from the computer interface so that each column of the 5 X 7 matrix is timed to release the droplets in registered and aligned relationship on the moving web regardless of its speed.
  • the pulse stream output from each matrix generator is converted by digital-to-analog conversion circuitry, a separate circuit being responsive to each of the matrix generators, whereby a low level video ramp signal representing seven different voltage levels for each column of the matrix is produced.
  • the low level video signals are amplified and provided as control voltages to a charging tunnel whereby each of the successive drops in the droplet stream projected from each nozzle is charged in accordance with its desired displacement along an axis transverse to the movement of the web.
