A distance measurement method for use in a laser range finding device to measure a distance between the laser range finding device and a target is disclosed. Moreover, a method for manufacturing a pipe based on the method for determining the strain hardening property of the pipe, a pipe manufactured by means of the method for manufacturing the pipe, and a pipeline are proposed. Four pre-established LUT databases and an interactive four-matrix lookup table process are implemented to determine actual coordinates of the object on in the planar area. The second plate cylinder 26 is individually driven by a second drive motor 46, and is engageable and disengageable from the associated second blanket cylinder 30 while the printing press is in operation, in order to perform flying edition changes or changes of a spot color.
