摘要： Described is a method for calibrating a position of a first register line in a register mark for a multi-color printing machine, said first register line consisting of a first color that does not offer sufficient contrast with respect to a printing material in order to allow a detection above a determined threshold value on a register sensor. In this method, first a plurality of register marks, each consisting of at least one starting line, a background line and a first register line, is printed, said background line consisting of a second color which offers sufficient contrast with respect to the first color for a detection above the specified threshold value on the register sensor if the first register line is printed on the background line, and said background line having a width that is by X mm greater than the first register line, and said starting line, said background line and said first register line being printed with the use of the pre-determined control parameters, which, in the normal case, cause the first register line to be printed on the background line. Subsequently, it is detected whether the first register line has been recognized by the register sensor above the pre-determined threshold value as being completely positioned on the background line. If this is not the case, then, in accordance with the method, at least one pre-determined control parameter for printing the first register line is changed and printing of the register marks and the detection are repeated. Changing of the at least one control parameter may be repeated one or more times, with the first register line being shifted each time with respect to its width with different algebraic signs. The above method is also particularly suitable as a pre-calibration of the first register line for a calibration pass for all colors of the multi-color printing machine.

摘要： A method for detecting errors in individual color separation images of a multi-color printing machine, in particular an electrophotographic printing machine, comprising a plurality of printing units, is described. Using this method, first a plurality of first register lines is printed with a first printing unit, and a plurality of second register lines is printed with a second printing unit in such a manner that each of the first register lines, together with one of said second register lines, is positioned inside a respective registration frame. Then the plurality of the first and second register lines in the respective registration frame are detected with a register sensor, and an output signal of the register sensor relating to the respective second register line is compared with an intensity threshold value in order to determine whether the second register lines can be recognized. In an alternative embodiment of the method, a plurality of the first register lines is printed with a first printing unit in such a manner that each of the first register lines is printed within a respective registration frame. Subsequently, the plurality of the first register lines in the respective registration frames is detected with a register sensor, and an output signal of the register sensor relating to the respective first register lines is compared with a pre-specified intensity threshold value in order to determine whether the first register lines are recognizable.
