  • This sheet 01 is in an industrial printing process with a printing machine 06 ( Fig.2 ) e.g. in a steel engraving process, preferably in an intaglio printing process, printed on at least one side, preferably on both sides, with at least one printed image 02.
  • the respective print motifs of printed images 02 printed on the front and back of the same sheet 01 are usually different from one another.
  • the sheet 01 shown has several panels.
  • the term panel refers to the number of copies of a printed product 03 arranged on the sheet 01, whereby the individual printed product 03 is, for example, a banknote to be produced or another document having at least one characteristic feature 04, in particular a security feature.
  • a security feature is to be understood as a characteristic property that proves the authenticity of this document and at least makes it considerably more difficult to forge this document.
  • the panels are arranged in the printed image 02 on the sheet 01 in several, e.g. two to eleven, in particular six columns a; b; c; d; e; f and in several, e.g.

All printed products 03 printed together on the sheet 01 should, within the permissible preset tolerances, have the same width b03 in the transport direction T of the sheet 01 and the same length l03 transverse to the transport direction T of the sheet 01.
  • the print image 02 printed on the originally rectangular sheet 01 has a width B in the transport direction T of the sheet 01 and initially a first length L1 perpendicular to the transport direction T, whereby this initial length L1 can change to a different second length L2 during the printing process.
  • the sheet 01 is subjected to very high mechanical pressure during the printing process as it passes through the printing machine 06, so that the sheet 01, which is rectangular in the unprinted state, and thus also its printed print image 02, are deformed in a particular trapezoidal shape.
  • This deformation of the sheet 01 can make the print image 02, which is actually supposed to be rectangular, symmetrical to an isosceles trapezoid, or unequal-sided.
  • the trailing end of the sheet 01 in the transport direction T forms the base of this trapezoid.
  • the second length L2 of the print image 02 corresponding to this base of the trapezoid is thus in practice somewhat larger after execution of the printing process than the actually intended length L1 of the print image 02, which is in the transport direction T of the sheet 01 at the leading end of sheet 01.

  • These margin regions R2; R3 are also each referred to as a side margin R2; R3.
  • the respective width r2: r3 of the relevant side margin R2; R3 lies in a range, for example, between 5 mm and 30 mm, whereby the widths r2; r3 of these margin regions R2; R3 can be the same or different in terms of amount.
  • the gripper edge R1 and the two side margins R2; R3 enclose the print image 02 having multiple copies printed on the sheet 01 on three sides.
  • a border area extending longitudinally to the second length L2 of the print image 02 is also provided on the rear edge of the sheet 01 in the transport direction T, which again forms a boundary line, whereby the width of the border at the trailing end of the Sheet 01 is in a range e.g. between 5 mm and 40 mm.

  • the reference point P i.e. the coordinate origin for coordinates x; y for identifying the position of a characteristic feature 04 in at least one of the printed products 03 generated by the printed image 02, is located, for example, in the right-hand corner on the front side of this printed image 02 in the transport direction T of the sheet 01.
  • a deformation of the sheet 01 and the printed image 02 applied to it due to the printing process changes the respective length l03 and/or the respective width b03 of individual printed products 03, whereby such a change must not exceed a deviation from corresponding target values of, for example, ⁇ 1 mm, particularly in the case of printed products 03 each designed as a banknote.
  • the position of the relevant characteristic feature 04 also changes relative to the specified boundary lines of the relevant printed product 03.
  • Such a change in the position of the relevant characteristic feature 04 must not exceed a deviation from the target position of, for example, ⁇ 1 mm, particularly in the case of printed products 03 each designed as a banknote. If these permissible preset tolerances are exceeded, the relevant printed products 03, particularly if they each form a banknote, must be removed from the ongoing production process as waste and/or destroyed.
  • the printed products 03 printed using the multi-sheet technology can be clearly identified with regard to their respective position on the respective sheet 01 because each of these printed products 03 has an identification feature 09.
  • each of these printed products 03 is provided with a serial number that runs consecutively in the production process.

  • the "best fit" adjustment is carried out by applying a mathematical optimization method.
  • a compensation calculation or a computationally performed approximation procedure can also be used as a mathematical optimization method.
  • the production process can focus more on the quality of the print products 03 produced or on the quantity of the print products 03 to be produced.
  • the "best fit" adjustment can therefore be made as needed in the sense that in a certain production process either as many printed products 03 as possible are produced with a quality that is just good enough or a high-quality production is carried out with a comparatively smaller number of printed products 03. This decision can be made individually before or at the start of production by choosing the appropriate optimization method.
