Definitions

  • the invention relates to an apparatus for applying an ink image to a receiving material.
  • the invention relates to copiers or printers, more particular to photocopiers or inkjet printers, wherein the receiving material is retained against a carrier plate.
  • the invention further relates to a method for applying an ink image to a receiving material.
  • the carrier plate is, for example, provided with V-shaped channels, which extend in the direction in which the receiving material is movable stepwise over the carrier plate.
  • Ribs which separate the channels from one another are provided with suction openings in order to draw bubbles, which are formed by moisture absorption in the receiving material, into the channels by vacuum pressure, in order to prevent said bubbles from coming into contact there with ink application means which are flatly movable over the carrier plate.
  • the receiving material is pulled against the carrier plate with considerable force so that it is possible to ensure with a great degree of certainty that parts of the receiving material, particularly bubbles projecting in the direction of the ink application means, remain out of contact with the ink application means.
  • a disadvantage of the known apparatus is that the ink images on some receiving materials are distorted due to, for example, locally occurring line broadening and density variations in area-fills.
  • An object of the invention is to improve on this.
  • a further object of the invention is to provide an apparatus having an improved control over the process of the application of an ink image onto the receiving material in order to, at least, reduce the distortions mentioned above.
  • the invention provides an apparatus for applying an ink image to a receiving material adapted to be advanced in a direction of advance, comprising:
  • Some receiving materials are pulled into the recesses to some extent due to the vacuum pressure. On the one hand this is favourable since it reduces the extent to which bubbles project in the direction of the ink application means. On the other hand the sagging of the receiving material into the recesses may result in positioning errors in the ink image.
  • the ink image of these dots is distorted when the line crosses a part of the receiving material that has sagged into a recess.
  • the distance between the dots on the receiving material will increase when the ink application means move over a downward slope of the sagged receiving material. This distance will decrease when the ink application means move over an upward slope of the sagged receiving material. Since this distortion of the ink image is repeated in each strip of receiving material, these distortions add up to form a pattern in the direction of advance of the receiving material.
  • the carrier plate can be provided with a series of regularly spaced recesses or channels as known in the art.
  • the above-mentioned distortions appear around the position of each recess, so that these distortions add up to form a longitudinal wave pattern in a direction perpendicular to the direction of advance of the receiving material.
  • Providing the apparatus for applying an ink image to a receiving material with correction means for, at least partially, correcting local variations in the distance between the receiving material and the ink application means, may result in a substantial improvement of the ink image due to the reduction of the misalignment of the ink dots which make up the ink image.
  • the correction means comprise timing means for adjusting the moment of ink release by the ink application means.
  • Local distance variations cause variations in flight time of the ink droplets from the ink application means to the receiving material.
  • Said variations in flight time of the ink droplets can be compensated by adjusting the moment of ink release. For example, when the receiving material has sagged into a recess, the distance between the receiving material and the ink application means is locally enlarged and the flight time of the ink droplet will increase. Advancing the moment of ink release by the ink application means can compensate this increased flight time and can correct the misalignment of the position of the ink droplet due to the sagging of the receiving material into the recess.
  • the timing means are arranged for advancing the moment of ink release when the ink application means is near a downward slope of a recess, and for delaying the moment of ink release when the ink application means is near an upward slope of a recess.
  • the advance and delay are defined by an undulatory electronic signal, wherein the leading and tailing edges of the undulatory signal correspond to the downward and upward slopes of the recesses, respectively. The differences in flight time can thus be corrected using a simple electronic correction of the signal that controls the moment of ink release by the ink application means.
  • the application means are arranged for moving with uniform velocity over the carrier plate.
  • the undulatory electronic signal is also regular, and a simple regular electronic wave signal can be used.
  • the correction means comprise speed adjustment means for adjusting a relative velocity between the ink application means and the carrier plate.
  • the speed adjustment means are arranged for reducing the relative velocity when the ink application means is near a downward slope of a recess, and for increasing the relative velocity when the ink application means is near an upward slope of a recess. Due to this variation in relative velocity between the ink application means and the carrier plate, the trajectories of the ink droplets can be adjusted to compensate for said local distance variations between the ink application means and the receiving material.
  • This adjustment of the relative velocity between the ink application means and the carrier plate can be carried out with the speed adjustment means which comprise translation means for moving the carrier plate in the direction substantially parallel to the direction of the strip of receiving material.
  • the translation means are arranged for a reciprocating movement of the carrier plate.
  • the speed adjustment means comprise means for adjusting the velocity of the ink application means.
  • This adjustment of the velocity of the application means may be defined by an undulatory electronic signal, wherein the leading and tailing edges of the undulatory signal correspond to the downward and upward slopes of the recesses, respectively.
  • the variation of the velocity can thus be achieved by a simple electronic correction of a signal for controlling the velocity of the ink application means.
  • the above-mentioned means for adjusting the velocity of the ink application means and the translation means for moving the carrier plate in the direction substantially parallel to the direction of the strip of receiving material can also be combined.
  • the required adjustment of the relative velocity between the ink application means and the carrier plate can be divided between said means for adjusting the velocity of the ink application means and said translation means. In this way the amount of adjustment of each of these means can be reduced.
  • the velocity of the translation means for moving the carrier plate can be reduced.
  • a further advantage of the above mentioned first and second embodiments is that the distance between the carrier plate and the ink application means is not affected by the correction means. Thus the risk that the receiving material may come into contact with the ink application means is as low as in the prior art.
  • the correction means comprise adjustment means for locally adjusting the distance between the ink application means and the carrier plate.
  • this adjustment results in essentially a constant distance between the ink application means and the receiving material.
  • This adjustment of the distance may also be defined by an undulatory electronic signal where the leading and tailing edges of the undulatory signal correspond with downward and upward slopes of the recesses.
  • the adjustment means comprise first movement means for moving the carrier plate in a direction for adjusting a distance between the ink application means and the carrier plate.
  • the adjustment means may also, or in addition, comprise second movement means for moving the ink application means in a direction for adjusting the distance between the ink application means and the carrier plate.
  • first and second movement means the extent of adjustment can be divided between these two movement means, thereby reducing the required amount of adjustment of each of these movement means.
  • the apparatus further comprises controlling means for controlling the correction means depending on of at least one of the following characteristics selected from the group comprising: receiving material characteristics, ink characteristics, ink image characteristics, print mode, carrier plate characteristics, distance between the ink application means and the carrier plate, and the velocity of the ink application means with respect to the carrier plate.
  • controlling means for controlling the correction means depending on of at least one of the following characteristics selected from the group comprising: receiving material characteristics, ink characteristics, ink image characteristics, print mode, carrier plate characteristics, distance between the ink application means and the carrier plate, and the velocity of the ink application means with respect to the carrier plate.
  • the controlling means control the correction means for correcting this estimated extent of sagging of the receiving material into the recesses.
  • the use of such a controlling means results in a very flexible apparatus, which can easily adapt to various conditions such as, for example, various different types of receiving materials.
  • controlling means comprise input means for inputting said characteristics.
  • One or more of said characteristics or values defining the state of said characteristics may be inputted or modified via said input means when changing, for example, from one type of receiving material to an other type of receiving material or from one type of printing ink to an other type of printing ink.
  • Said values may be numerical values, but may also comprise other characters, such as alphanumeric characters.
  • the receiving material characteristics may comprise at least one of the characteristics selected from the group comprising: the grade, the type, the thickness, the moisture content, the weight or substance per unit area, and the sizing.

  • best mode the ink image is printed in more than one forward motion or reciprocating motion.

  • the apparatus comprises detection means for detecting the positions of the recesses with respect to a path of the ink application means.
  • the information about the relative position of the recesses with respect to the path of the application means can then be transferred to the controlling means.
  • This information can be used for controlling the correction means as described above.
  • Said detection means can be used for calibration or recalibration of the correction means and may for example be used in a start-up phase of the apparatus according to the invention for detecting the relative positions of the recesses with respect to the actual path of the ink application means.
  • the invention provides a method for applying an ink image to a receiving material using an apparatus adapted to advance the receiving material in a direction of advance, wherein the method comprises the steps of:
  • Said correction can be performed by adjusting the moment of ink release by the ink application means, using timing means as described above.
  • said local variations can also be corrected by adjusting the relative velocity with which the ink application means is moved over the carrier plate for applying the ink image to the strip of receiving material.
