Title: Innovations by Hans Koehler in Inkjet Printing Technology
Introduction
Hans Koehler is a notable inventor based in Edingen-Neckarhausen, Germany. He has made significant contributions to the field of inkjet printing technology, holding a total of eight patents. His work focuses on improving the quality and efficiency of printing processes, particularly through innovative methods that enhance the performance of print nozzles.
Latest Patents
Koehler's latest patents include a method for assessing the condition and improving the printing quality of printing nozzles in printheads of an inkjet printing machine. This method involves printing a nozzle test chart with a specific number of horizontal rows of equidistant vertical lines. Only every n printing nozzle contributes to the test chart in each row, with n corresponding to a different number. The test chart is recorded and digitized for analysis regarding the condition of the contributing nozzles. The analysis is performed using a computer, which also implements measures to improve the printing quality based on the condition of the nozzles.
Another significant patent addresses density fluctuation compensation during print head replacement. This method compensates for position-dependent density fluctuations of print nozzles in an inkjet printing machine. A computer generates compensation profiles for these fluctuations across all print heads and substrates. When print heads are replaced, the computer calculates a new compensation profile for the specific substrate, ensuring consistent print quality.
