5.14. Positioning marker for cutters

The marker can consist of one or two elements. An element is a vertical or horizontal line in black. The marker can be drawn as "linked" to the selected paper edges or centrally. It can change its location (or not) together with the image of the imposition.

Applies only to the assembly of leaflets.

Panel with marker definition

  • [1] The name of the marker. It can be your own.
  • [2] A group of switches regulating the spacing between the longitudinal and transverse knives.
  • [3] The switch that enables drawing a marker on an odd or odd and even pages.
  • [4] The key saving marker’s definition.
  • [5] A drop-down panel containing elements defining the appearance of one or two elements that make up the marker.

A panel with elements regulating the appearance of marker elements

  • [1] Element’s number switch.
  • [2] A switch that draws or stops drawing an element.
  • [3] The switch to adjust the position of the element (on the left or right edge or centrally).
  • [4] A group of switches that adjust the horizontal sizes and position of the element. One of the switches from each group (one of three) must have the VARIABLE status.
  • [5] A group of switches that adjust the horizontal sizes and position of the element. One of the switches from each group (one of three) must have the VARIABLE status.

At the time of installation, three mark definitions are available for the most popular machines (Marker's definition 1, Marker's definition 2 and Marker's definition 3). Marker’s names can be freely changed. Turning on marker drawing automatically switches the type of print to Digital print (in the side panel DIGITAL PRINT/OFFSET PRINT). The number of the selected marker is stored in the imposition file (*.impozycjoner).


Positioning marker for cutters – example 1

An example of a marker definition from the cutter documentation. The marker consists of two elements.

After separating each element, the definition of the first element is as follows:1

  • defining horizontal dimensions of the first element:

  • defining vertical dimensions of the first element:

Definition of the second element is following:


Positioning marker for cutters – example 2

Sample definition of the marker from the cutter documentation:

The marker consists of one element. It’s definition in the program is as follows.

Drawing of the second element is turned off:

The location of the marker is closely related to the edge feeding the sheet to the printing machine.

The correctness of the positioning markers is easy to check by placing the whole imposition on the mock-up in the form of a millimeter grid. An additional element drawn by the program (in addition to the marker elements) is a white rectangle between the feeding edge of the sheet and the marker, “cleaning” the surface for reading optical elements of the cutter.

Adjusting the spaces between the knives

Adjusting the spaces between the knives of the cutter (parallel and transversal) takes place by temporarily changing the bleeds of the use. The bleeds with the drawing of the positioning marker on the cutters may be different than those defined during the design/filling of the sheet.

The spaces between columns or rows (i.e. spaces between the cutter knives) is the sum of the values of the respective bleeds, e.g. left and right, lower and upper.

Changing the page orientation does not change the spacing between the knives. The change in the definition of transverse and longitudinal knives may take place with the change of the feeding edge.

Longitudinal knives are knives cutting the sheet in the direction of sliding the sheet in the cutter (perpendicular to the feed edge). Transverse knives - are knives perpendicular to the direction of the sheet moving in the cutter (parallel to the feed edge).
