Definitions

  • the invention relates to the color printing of a support sheet. thermal transfer, thermal sublimation or other printing thermal printing modes.
  • Color thermal printers use as printing consumable a support tape for a succession of sets of coloring ranges.
  • Each set of ranges usually includes three ranges successive colors of cyan, magenta and yellow, each range having the dimensions of a sheet to print.
  • Printing a page therefore systematically consumes three color areas regardless of the size of the image to be printed, this which results in a waste of ribbon, for example when you do not print only a few lines of the page.
  • the invention aims to regulate the consumption of coloring tape depending on the size of the image to be printed while avoiding defects printing.
  • the invention relates to a printing ribbon printer for office machine printer supporting succession of coloring areas intended to print an image in au minus one print area on a print media sheet of determined format, characterized in that the formats of the tracks coloring are substantially sub-multiples of the sheet format print medium but significantly different from each other.
  • the formats of the successive coloring ranges intended for printing a printing area are decreasing.
  • the printing ribbon 1 which will now be described is intended to be used as a printing consumable in a color thermal transfer printer for office.
  • the tape 1 here comprises a polyethylene film 2 supporting a succession of coloring areas 3 - 7 of different colors consisting of resin layers containing pigments of coloring.
  • Ribbon 1 is subdivided into a plurality of sets of tracks 4 - 6 each intended for printing a printing area of a support sheet and comprising a plurality of successive ranges of different colors, in the species three respective color ranges cyan, magenta and yellow.
  • the ribbon being intended for printing support sheets printing format, in this case standard A4 format (21 cm x 29.7 cm), the coloring areas here have a format substantially equal to half of standard A4 format, i.e. A5 format (21 x 14.85 cm), the short sides of the coloring areas extending parallel to the edges of the ribbon.
  • the widths of the coloring areas 4 - 6 of each set of ranges, intended to print a printing area of a print media sheet are noticeably different from each others and here decreasing.
  • the formats of the tracks successive dyes of each set of ranges are substantially submultiples of the format of the sheet to be printed, but substantially different from each other and decreasing. Thanks to this, we can smooth the connections between the printing areas as will be explained by the after.
  • Each printing strip 9 (9 ') is then submitted, one after another, in a succession of printing passes 10, 11, 12 (10 ', 11 ', 12'). For each printing pass, we train the band 9 (9 ') in a round trip and we print a color during the movement go by applying a coloring area on the strip and activating heating elements of a print head.
