Title: Innovations by Roger Vinas
Introduction
Roger Vinas is a notable inventor based in Barcelona, Spain. He has made significant contributions to the field of printing technology, holding 2 patents that enhance the performance and efficiency of printers. His work primarily focuses on compensating for sensor drift and controlling printer temperature.
Latest Patents
One of Roger Vinas's latest patents is aimed at compensating for drift and sensor proximity in scanning sensors used in color calibrating incremental printers. This invention involves taking a measurement of the bare print medium's tonal value in immediate juxtaposition to each color test pattern. The measured bare-medium tone is then utilized to correct color-patch readings. The system employs a line sensor on the scanning printhead carriage to perform these readings, ideally taking two readings at each end of the test pattern. This method also includes separate scans of the bare medium to develop long-term and short-term drift profiles for refining corrections.
Another significant patent by Vinas is a system and method for controlling printer temperature. This invention provides thermal protection to printheads in large format inkjet printers. The adaptive thermal print swath servo (ATPSS) module divides a print operation swath into individual cells, allowing for precise temperature management. If any printhead is predicted to exceed a maximum allowed temperature, the ATPSS module can divide the upcoming pass into a series of sub-passes. This innovative approach helps preserve the life of printheads by preventing excessive heat generation.
