A printer according to the present invention includes a transfer roll and a plurality of the printing rolls. At least one printing roll of the plurality of the printing rolls transfers ink containing a conductive material to the transfer roll. Preferably, the at least one printing roll includes a printing roll configured to transfer ink containing a conductive material to the transfer roll and a printing roll configured to transfer ink containing a conductive material to the transfer roll.

A method of printing on a web of paper includes the steps of providing the web, adjusting a tension on the web and sequentially printing each of a plurality of different indicia on defined sequential longitudinally spaced printing fields of the web. Information is then printed in each of the defined printing fields on the web. Preferably, the method is used for printing bingo game booklets in which each sheet of the booklet is identified by a different color or border than is each other sheet in the booklet. The apparatus includes a roll stand from which the web is fed and an indicia printing unit. The indicia printing unit includes a plurality of indicium rolls supported by and spaced around a frame and an endless printing belt supported by the rolls, the printing belt having a plurality of sequentially longitudinally spaced print areas. The endless printing belt is looped around a register cylinder and an impression cylinder is provided around which a paper web is looped as the web is brought into contact with the endless printing belt to print a sequence of different printing fields, each designated by a different indicium from each adjacent printing field on the paper web. A first control system automatically regulates which portions of the belt contact which of the indicium rolls and in what sequence.
摘要:
A method of printing a color image on a medium, the method comprising the following steps: separating the image to be reproduced into a composition of colored unit areas, said unit areas being disposed in a predetermined distribution, the color of each unit area being selected from a predetermined set of base colors and a predetermined set of tones of said base colors, the number of tones for at least one of the base colors being greater than or equal to three, the base color and the tone allocated to each of said unit areas being selected so that said composition of colored unit areas visually reconstitutes the image to be reproduced; and printing said composition of colored unit areas on said medium by means of inks whose hues are selected, taking into account the color of said support, so as to be capable of reproducing said base colors and the tones thereof during printing, the tone of a base color allocated to a given unit area being obtained during printing by acting on the proportion of each ink within the corresponding unit area on the medium.

A method and apparatus for multicolor printing of paper webs. The method provides a means for printing creped paper webs while maintaining precise control of color register in spite of any stretching of the web during the printing process. Apparatus is disclosed which comprises a plurality of rotary printing plates, each inked with an ink of an independent color, and a single blanket cylinder for transferring the colored inks in proper register from the plates to the blanket and from the blanket to the web. The blanket cylinder or the impression cylinder or both may be segmented which permits printing selected portions of the web without ironing out embossments in other areas of the web by the printing rolls.

A second color print head attachment for an offset duplicator including a plate cylinder carrier 20 and an inker carrier 70 arranged to be pivotally secured to a side frame 11 of an offset duplicator press 10. A first pair of register pins 100 and 102 mounted on the inker carrier 70 are received in openings 21 and 23 formed in the plate cylinder carrier 20 for detachably securing inker form rollers 75, 76, and 77 in engagement with the printing plate 35. A pair of rollers 64 and 66 on the plate cylinder carrier 20 extend into guide slots 54 and 56 in a mounting bracket 50 secured to the duplicator press frame 12. The lock-up mounting bracket 50 and the hinge mounting bracket 40 are pivotally secured to the duplicator press frames for rotation by an eccentric actuator 110, 115 for moving the printing plate 35 into engagement with the blanket cylinder 16 in the duplicator press 10. The inker carriage 70 and the plate cylinder carriage 20 can be swung away from the blanket 16 of the duplicator press either separately or in combination.

A collect-printing unit for security printing in offset printing for use in a rotary printing press, provided with a blanket cylinder to which a plurality of cut-out offset rollers are coordinated, is disclosed. Two ink transfer cylinders and one forme cylinder, on whose periphery a plurality of offset printing formes are fixed, are coordinated to this blanket cylinder. Another blanket cylinder is coordinated to the forme cylinder, this blanket cylinder taking the multi-color motif to be printed from the forme cylinder and transferring it onto the support to be printed. A counter pressure cylinder may cooperate with this blanket cylinder. A sheet-shaped or web-shaped support to be printed is interposed between the blanket cylinder and the counter pressure cylinder and is printed in offset collect-printing.

To match the width of zone adjustment of doctor blade elements or zones of a continuous doctor blade of a printing machine inking system to pick up units of photoelectric transducers scanning patterns, in columnar zones, so that the degree of inking of the ductor roller can be matched to the degree of printing density of the pattern in the respective zones by control of the doctor blade elements or zones, the transducer arrangement includes a plurality of transducer elements of selectively different transducing widths, associated with the zones of information coverage of selectively different widths to match the width of the transducing means to the zones and for transmission of thus matched transduced signals to the printing apparatus and derive an output of utilization signals with respect to the zones of selectively different widths. Transducing elements of respectively different widths may be used (FIG. 3); or much narrower transducing elements, the outputs of which are then combined in a summing circuit and in which the number of the transducing elements, transverse to the transport direction of the pattern, is equal to the common divisor of the zone width (e.g. for zone widths of 30, 35, 40 mm, a transducer width of 5 mm); or transducers of fixed widths can be located on parallel arms of a scissor grid, the relative inclination of which with respect to the transducing direction can be changed, to provide for infinitely variable overlap, and coverage of the width of the pattern, in zones of infinitely variable dimension.
摘要:
A two-color offset printing press having two plate cylinders simultaneously engageable with a single blanket cylinder is disclosed. The plate cylinders and the blanket cylinder are rotatably mounted on a printer head fixed to the mainframe of the press. A first set of dampening and inking rollers is mounted on the printer head and engageable with one of the plate cylinders. A second set of dampening and inking rollers, engageable with the other plate cylinder, is mounted on a ball bushing supported carriage linearly movable to and from the printer head along a pair of parallel rails fixed to the mainframe. Image registry between the two plate cylinders is established by an operator-accessible adjustment mechanism for shifting one of the plate cylinders back and forth along its axis of rotation. An electrical safety interlock system precludes operator access to the carriage-associated plate cylinder during predetermined operating modes of the press.
