摘要
it has been a new tool and method for determination drucktechnischer parameters is developed. the invention relates to a pattern of aufzeichnungspunkten which is so reduced that the observer is almost invisible. this testtarget is microscopically enlarged and preferably via ccd camera.the signal to noise ratio of the measurement is increased by vorteilhafterweise, averaged over several consecutive print design. by means of advanced bildanalayse it is possible, due to printing technical parameters directly from the miniaturised patterns to determine. the measures to reduce the testtargets are described.the model application to the type of process control are outlined, which is mainly based on the geometrical characteristics of a certain punktmusters is based.
