Definitions
- the present invention relates to a printer techno ⁇ logy particularly aiming at graphical industries, in which it is actual to operate e.g. with more different printer types for different kinds of work.
- ⁇ •printer is an accepted technical designation for printing units, which, aided by computer controlled electronic control means, can be operated for instant activation/passivation while the medium to be printed is moved past the printer, such that the print picture can be built up with a desired high degree of resolution without the use of physical printing masters as in printing presses, for example.
- printer units Various basic technologies for the operation of the printer units have been developed, based e.g. on elec ⁇ trostatic charging and a following take-up of a toner or on the so-called ink-jet principle, where the printer unit effects a controlled, direct spraying on of the ink. It is possible to make plural colour prints by the use of more printer units arranged in a row.
- the machine construction of the printer apparatuses amounts to some 3/4 of their production price, and in the single enterprises long periods of time may occur, in which a certain type of printer is not used at all, i.e. in which this special printer with its required, relatively high capacity, is just passive.
- this special printer with its required, relatively high capacity, is just passive.
- the common control not only applies to the mechani ⁇ cal control, but largely also to the associated computer control of the movements, i.e. the superior control unit. For the latter it it without significance, in principle, whether the printing unit functions according to one or another technology, and particularly for this reason it is highly relevant that one same control equipment can be used for the practicing of the diffe ⁇ rent techniques.
- the basic equipment should be so adapted that it is able to effect transport at the higher of the velocities of the relevant techniques - and preferably still high ⁇ er, in anticipation of new and still faster techniques. Then, the basic equipment can be used over the entire range, from production jobs with relatively high copy numbers to preparation of printing masters for off-set, flexo and serigraphical printing.
- FIG. 1 is a perspective view of a first embodiment of a printer apparatus or system according to the inven ⁇ tion
- Fig. 2 is a similar view of another embodiment.
- Fig. 1 a printer cabinet 2 which, as a basic device, is without printing units, whilst other ⁇ wise having all equipment required for the transport of the web material 4 to be printed, just as it is prepared with various connector jacks for printing units 6 to be mounted in this device, such that these units can be connected to an associated control computer.
- the mounted units 6 may be electrostatically ope ⁇ rating printing heads capable of working at relatively high speed, e.g. with a capacity of some 800 m 2 /h for a web width of 150 cm.
- the basic device 2 can hold four printing units for making four colour prints, but situations may occur where more or fewer units are needed, and besides it will also be possible to place directly in the device 2 one or more after treating units, e.g. a lacquering unit and a drying unit, so this is the reason for the indicated available space in the device 2.
- the device can be used with but a single printing unit, be it for printing in one colour only or because the unit itself may print in more colours.
- Fig. 2 shows a printer apparatus for large sheets. including serigraphical frames.
- the apparatus has a mounting plane for a possibly frame or plate carried printing sheet 10, which in case of paper or foil will be fixed by suction through the support, and guiding rails 12 for a traverse 14, on which there is displaceably mounted a sledge 16 containing a print ⁇ ing or irradiating head. This head may then be control ⁇ led to sweep over the entire working area by a two di ⁇ mensional movement.
- Fig 2 it is additionally indicated that the basic apparatus can be alternatively used with the tra ⁇ verse 14 carrying a housing 20 for one or more printing units of the type shown in Fig. 1, i.e. units which should only move in one direction relative the working surface.
- the respective parts 14,16 and 14,20 may be mounted in a stationary manner, while the sheet 10 to be printed is moved by suitable moving means.
- the system may be orien ⁇ ted in the space as desired, also horizontally.
- the invention will provide for the marked ad ⁇ vantage that prior to the work being effected by means of an irradiation unit in the box 16 or the housing 20 it will be possible to obtain a transcript of the work ⁇ ing result, viz. by first running the control program with the use of a paper medium and a printing unit suit ⁇ able therefor. Upon examination of the printing result and consequentially needed adjustments, if any, of the control program, the operator may shift to a serigraphi ⁇ cal frame and an exposure unit, respectively. What is obtained is an absolutely reliable proof, being created based on control signals which are the same as will thereafter be used for the exposure, viz. by repetition from the same program source and moving mechanism.
- a provisio ⁇ nal order for 200 copies may have been planned for seri- graphic production, while, if the order is reduced to 50 copies, a suitable printing technique may be more suit ⁇ able, even when associated with a slower production in case of a high degree of resolution.
