Title: The Innovations of Ernst-Christian Maschler

Introduction

Ernst-Christian Maschler is a notable inventor based in Heidelberg, Germany. He has made significant contributions to the field of inkjet printing technology, holding a total of five patents. His work focuses on improving the efficiency and quality of inkjet printing processes.

Latest Patents

One of Maschler's latest patents is a method for feedback control of the temperature of ink in inkjet printing. This innovative method involves pumping ink through supply and return lines of an ink distributor and between these lines through print heads supplied in parallel with the ink. The process includes comparing a temperature actual value with a predefined temperature setpoint value and calculating a manipulated variable for a setpoint value of an ink heater based on the deviation between the setpoint and actual values. A flow sensor measures the flow of the ink, generating a measurement signal that is converted into a temperature auxiliary value for feedback control. This advancement enables continuous unimpaired production in industrial inkjet printing, particularly during changes in ink viscosity.

Another significant patent involves a printing machine equipped with an inkjet printing head, a radiation drier, and at least one light trap. This printing machine features separately controllable nozzles for applying ink to transported printing material. The radiation drier generates electromagnetic radiation to dry and cure the applied ink. The light trap serves as a barrier against reflected and scattered radiation, protecting the inkjet printing head from contamination. It includes a channel connected to an aspiration device that helps reduce or prevent contamination of the radiation drier.
