Definitions

  • FIG 2 A solution to this problem, of which a possible solution is illustrated in Fig 2 is that instead of a single vacuum chamber 8, the plate surface is divided into several fields each having their own vacuum chamber 8. Especially when the dimensions of these fields are chosen and designed in relation to common paper widths it is always possible to obtain a good vacuum to rigidly hold the receiving sheet in place. Vacuum chambers 8 outside the width of the receiving sheet may lose vacuum or may be switched of from the vacuum source, but have no influence on the holding power of those chambers 8 underneath the receiving sheet.
  • Vacuum is created and maintained by an air evacuation system.
  • the operation of the media transport system is a step-wise incremental transport .
  • the working area 4 of the receiving medium 15 is held on the base plate of the static table 1 it is possible to reliably print a swath of the image by shuttling the inkjet printhead 2.
  • the distance between the printhead 2 and the receiving material 15 is at the desired value as the base plate of the static table 1 is present over the whole length and width of the working area 4.
  • the invention can be used for the step-wise transport of a web material to be printed on, but likewise is would be possible to transport sheet material using the system.
  • An improvement shown in Figure 5 that could be used in sheet feeding is that the upstream edges of one or more vacuum tables 1,5,6 is bevelled to avoid that the leading edge of a sheet hits the upstream edge of the table and a deviation would occur in feeding the sheet.
  • the step distance can be variable as this can be necessary in certain recording methods .
  • the present transport system is capable to transport a web as shown directly from the feeding roll, although, dependent upon the type of medium to be fed, it may be advantageous to avoid tension on the receiving medium at the print location by providing a separate web feed module unrolling the feeding roll and buffering a lot of the feeding roll tension. This can provide even more accurate feeding. It has been found a significant advantage that the operation of the static/dynamic table media transport generates no shear forces in the receiving medium and that the receiving medium is in a "tensionless state" during printing.
  • An even more preferred embodiment of the removable static table sections 19 allows maximum support of the receiving medium 15 by not removing the whole of the static vacuum table section 19 but limiting the area that is removable from the static vacuum table section to the working area 4 of the printhead 2 or the shuttle, i.e. the area where ink or other marking material may be deposited. If the static table 1 is wider, along the direction perpendicular to the fast scan direction, than the width of a print swath, then only the area of the static table sections 19 corresponding with the area 4 of a print swath are removed or replaced with buckets 20.

Abstract

Cette invention concerne un procédé d'impression numérique selon lequel une table d'impression segmentée supporte normalement la zone de travail pendant l'impression. Pour qu'une impression sans bord ou un impression sur un matériau en treillis soit possible, on reconfigure la table d'impression statique en retirant ou en remplaçant certains de ses segments par des segments à godet ou par une gouttière destinés à recevoir les jets d'encre qui passent au travers ou à côté du support d'impression. Cette solution évite de contaminer la table d'impression statique, avec pour corollaire des taches et des tirages de mauvaise qualité.
