Definitions

  • ABSTRACT A process and device are provided for non-impact printing with liquid ink, in which ink dots of controlled size are printed at high speed on paper sheet or strip in accordance with desired printing patterns corresponding to printing control signals delivered by a data source. Electrically conductive ink is retained by capillary action in a plurality of uniform perforations in an electrically conductive ink-carrier provided with an ink-repelling layer.
  • the ink-carrier is maintained at a given constant potential and the paper sheet is placed between said ink-repelling layer and an array of electrodes which are selectively aligned with perforations of the ink-carrier and receive said printing control signals in the form of voltage pulses of given amplitude and short duration.
  • a localized electric field of controlled intensity and duration is thereby momentarily created between each selected electrode and the ink contained in the perforation in alignment therewith, so
  • the amount of ink transferred onto the paper during contact may be controlled to provide ink dots of given size by suitable adjustment of the amplitude and duration of the voltage pulses, as well as adjustment of the distance between the paper and the ink at rest in each perforation.
  • This invention relates to non-impact printing with liquid ink and in particular to producing printing patterns by selectively attracting ink onto a conventional sheetlike printing medium of ordinary paper or the like, whereby to form ink dots thereon in accordance with these patterns.
  • the invention may be used for the transcription, in printed form, of information received in the form of electric signals from any external data source, whereby to provide, for example, printed texts or curves corresponding to the information output of computers, electronic table calculators, measuring instruments, telegraph or teletype receivers, and of apparatus for the transmission of images, for facsimile printing or the like.
  • a printing device has also been proposed wherein an electrically insulating printing ink is retained in an electrically insulating, cylindrical screen.
  • the device further comprises means for negatively charging the ink according to an electrostatic pattern and a positively charged drum for bringing a printing medium into contact with the screen to allow ink transfer onto the medium in accordance with the electrostatic pattern,
  • said dielectric supporting medium for the latent image consists of a porous band on which the-latent image is produced on one side and ink is deposited on the opposite side, whereby to cause attraction of the ink through the pores of the band by means of the electrostatic charges of the image.
  • An ink pattern is thus formed for subsequent transfer onto a paper sheet or the like by contact thereof with said ink image.
  • the dielectric supporting medium thus simultaneously constituts a latent image support and an inking member.
  • printing involves three consecutive steps, namely image formation, ink attraction to the surface, and ink transfer to the paper by contact printing.
  • Such a process has several limitations, in particular with regard to the control of selective ink transfer at high speed.
  • the ink retained in the insulating screen is uniformly positively charged and the device comprises means for negatively charging the printing medium according to an electrostatic pattern, as well as means for moving the medium into contact with the screen to transfer the positively charged ink onto the medium in accordance with the electrostatic pattern, by the electrostatic force between the ink and the medium.
  • the abovementioned problems of ensuring precise control of ink transfer and of preventing arbitrary ink transfer nevertheless remain the same in this variant.
  • a principal object of the invention is to allow highspeed non-impact printing with liquid ink while largely obviating the above-mentioned drawbacks and limitations.
  • Another object of the invention is to allow controlled attraction of the ink so as to provide high speed ink transfer for printing ink dots of predetermined size.
  • a further object of the invention is to rapidly produce printed patterns having high-resolution by printing ink dots with high definition, the size whereof may be varied within certain limits, while using the same printing system.
  • Another object of the invention is to provide highquality facsimile printing in such a manner as to print dots of different size, whereby to provide a progressive tonal range in the printed image.
  • Still another object of the invention is to provide means for completely eliminating any uncontrolled ink transfer during printing.
  • the present invention provides a method of nonimpact printing with a liquid ink on a sheet-like dielectric printing medium consisting of ordinary paper or the like, by producing ink dots thereon in accordance with printing signals corresponding to a desired printing pattern, said method comprising the steps of:

  • the invention further provides a device for printing with liquid ink on a sheet-like dielectric printing medium, by producing ink dots thereon in accordance with printing signals corresponding to a desired printing pattern, said device comprising:
  • a perforated, electrically conductive ink-carrying member having a correspondingly perforated inkrepelling layer arranged on one side thereof, with a plurality of capillaryperforations of same size traversing said member, said perforations having an electrically conductive ink retained therein by capillary action;
  • a printing head comprising at least one electrode having a size such as to allow selective arrangement and in alignment with one of said perforations;
  • means for delivering said printing signals to the printing head in the form of brief voltage pulses of predetermined amplitude and duration, so as to momentarily create a localized electric field of predetermined intensity extending between said electrode receiving said pulse and said ink-carrying member, to thereby provide selective ink transfer from the said selected perforation and to thereby print an ink dot of predetermined size due to said ink transfer onto said medium.

  • the drive system 10 may comprise any suitable drive means, such as an electric motor equipped with transmission means for example a toothed belt and gear system.
  • This motor may be either a constant-speed motor for providing continuous movement of the inking ribbon 1 and the paper strip 6, both at the same speed, or else a stepping motor for providing synchronized step-bystep movement wherein the inking ribbon l and the paper strip are stationary between consecutive steps thereof to allow ink transfer.
  • the pulse generating means 18 may likewise comprise any circuit of conventional design capable of selectively delivering to each of the electrodes 17 of the printing head a series of printing signals S in the form of voltage pulses of controlled amplitude and duration,
  • signals being delivered in accordance with data corresponding to a desired printing program.
  • This data may be received from any outside programming means,
  • the pulse generating means 18 may have any conventional design and need not constitute a part of the printing apparatus proper but may readily be a part of the printer programming means, it has been illustrated by the block 18 and will not be described in detail.
  • the structure of the inking ribbon 1 and its relative arrangement with respect to the paper strip 6 and to the printing head 5 are shown in enlarged cross-section in which is maintained therein by capillary action as is indicated very schematically in FIG. 4a by the liquid column 20.
  • The'ink-carrying ribbon 1A must be electrically conductive and may be made, for example, of stainless steel, nickel, copper or aluminium, which is rendered more wettable (hydrophilic) by physical or chemical treatments such as are well known in the printing art.
  • the layer 1B must be ink-repelling and any suitable known hydrophobic coating material such as tetrafluoroethylene (Teflon) or certain silicone compounds may be used for forming this layer, for example, by spraying onto the perforated metallic ribbon 1A.
  • Teflon tetrafluoroethylene
  • the conductive ribbon 1A may also envisage subjecting the conductive ribbon 1A to a surface treatment, such as electrolytic polishing, so as to provide its surface with hydrophobic properties.
  • a surface treatment such as electrolytic polishing
  • the ink-repelling layer 1B lies between the conductive ink-carrying ribbon 1A and the strip 6 of printing paper and it has been found in practice that this provides a significant result with regard to the obtention of faultless printing at high speed.
  • experimental results have consistently shown that ink transfer can be precisely controlled to provide printing of ink dots of given size at high speed.
  • the exact action of the inkrepelling layer 18, in this regard cannot be fully explained.
  • FIG. 4a shows various system parameters related to the dimensions of the composite inking ribbon l and to its relative arrangement with respect to the printing medium (paper). These parameters are:
  • FIG. 4b shows three consecutive perforations of a longitudinal row, with the first and third perforations, containing ink at equilibrium under the effect of capillary action, while the ink is being attracted from the second perforation for transfer thereof onto the paper.
  • the inking ribbon 1 is further provided with spacers 21 which are fixed to the conductive ribbon 1A, and project through the layer 1B so as to come into contact with the paper 6 and thus determine the spacing x (see FIG. 4a) between the paper and the layer 1B.
  • Theperforations ll of the inking ribbon 1 all have the same size and may either be cylindrical (constant diameter) or, as is indicated on the left-hand side of FIGS. 4a, 4b, may have a cross-section which increases towards the free (inner) surface of the ribbon 1A, where ink is supplied by the feed means 12 (see FIG. 1).
  • the use of such perforations with increasing crosssection has been found to be advantageous with regard to the introduction of the ink and the retention thereof in the perforations by capillary action, the meniscus of the ink being formed and held at that part of the perforations having minimum diameter. It is understood that FIGS. 4a and 4b merely show a conceptual model, but experimental results indicate that the ink meniscus is deformed and behaves in the general manner illustrated very schematically in these figures.
  • the degree of deformation of the ink meniscus will evidently depend on various parameters such as: the attracting trajectory (V), the perforation diameter (b, the distance across which the meniscus must be displaced for contact with the paper (h,, and x possibly tending to zero), the duration of attraction, the surface tension and the viscosity (;1.) of the ink.
  • the curve of FIG. 5 shows (for (I): 0.2 mm) the variation of the maximum air gap at (see FIG. 4a) allowing ink transfer onto the paper, as a function of the inkattracting potential V,,, i.e. the amplitude of the voltage pulse applied to the electrode, the duration i of the pulse being constant at 9.5 m/s.

  • the ink used, as well as the materials and thicknesses h, and [1,, of the hiking ribbon are the same as indicated above with reference to FIG. 5.
  • the curves of FIGS. 7 and 8 respectively show the influence of the viscosity [1. and of the surface tension 0' of the ink on the minimum potential V necessary to provide ink transfer.
  • a composite copperteflon inking ribbon was used with (b 0.2 mm, h, 0.1 mm and k 0.05 mm.
  • the surface tension 0' is constant at 68 dynes/cm in the ink used for the curve of FIG. 7, while the viscosity p. of the ink is constant at 1 cp in the ink used for the curve of FIG. 8.
  • the duration 1,, of the voltage pulses was also 9.5 ms, as before.
  • the conductive ribbon 1A is highly wettable by the ink, as compared to the inkrepelling layer (1B).
  • the use of a gap of small height of up to about 0.1 mm seems advisable for various practical reasons, in particular when the inking member and the printing medium are displaced at high speed during printing.
  • the voltage pulse duration t was found to be much higher than the minimum response time necessary for ink transfer.
  • the minimum pulse duration necessary for printing depends on various dimensional and operational parameters, as well as on the properties of the ink, and is thus difficult to determine for all cases.
  • the pulse duration t may be reduced to 4.5 ms without substantially modifying the relationships shown in FIGS. 5 to 8.
  • FIGS. 9, l0 and 11 respectively show the variation of the size (1),, of the printed ink dots, as a function of V t and x, when using the same ink with 0' 39 dynes/cm and p. 1 cp.
  • FIG. 9 shows three curves giving dot size as a function of V,, and corresponding respectively to t 9.5, 4.6 and 0.4 ms (for 0.2 and x 0.04 mm).
  • the curves of FIGS. 9 and 10 (same ribbon and ink) thus show that the influence of pulse duration t on dot size (1),, is appreciable in the considered range.
  • FIG. 11 moreover shows the influence of the gap size x on the dot'size (1),, for t,, 9.5 and 0.4 ms respectively (for d) 0.3 mm, h,, 0.1 mm, k 0.04 mm and V 1,750 volts).
  • This figure thus shows that the gap size is also a significant parameter with regard to (lot size which varies between 0.2 and 1.4 mm in the curve of FIG. 11.
  • the ink used for printing according to the present invention must be electrically conductive, although the conductivity thereof is not critical and may vary over a broad range.
  • any ink based on a polar solvent for example a water-based ink, may be used for the purposes of the invention.
  • the above described structure of the inking ribbon, the arrangement of the conductive ink-carrying ribbon at a-short predetermined distance from the surface of the printing paper, and the described association thereof with electrodes adapted to receive the printing signals from a data source, in the form of well determined high-voltage pulses of short duration, for attracting ink from the ribbon onto the paper, provide a par-- keep the ink within the inking ribbon whereby to prevent uncontrolled ink transfer in the absence of an electric field acting thereon, while allowing instantaneous deformation of the meniscus for contact thereof with and ink transfer to the paper, when a voltage pulse is applied to an electrode situated on the opposite side of the paper, in alignment with the meniscus.
