Title: The Innovations of Karl Lang

Introduction

Karl Lang is an accomplished inventor based in Madison, WI (US). He holds 2 patents that showcase his expertise in the field of printing performance and color calibration systems. His work has significantly contributed to advancements in technology, particularly in the areas of diagnostic imaging and color accuracy.

Latest Patents

One of Lang's latest patents is focused on diagnostic targets for evaluating printing performance. This innovation involves printing a diagnostic image that comprises color patches. The colorant usage in the printed image is measured by scanning each patch, and the measured color values are compared to target color values. This process allows for the identification of groups of patches whose color values vary significantly from expectations. Additionally, it analyzes variant groups to identify color quality control problems and spatial issues that may affect localized areas of a printed page. A heat map can be generated to help operators visualize these spatial problems.

Another significant patent by Lang is a color reference system for display monitors. This system includes a visual display terminal (VDT), a color calibration sensor, and a computer processing unit (CPU). The VDT produces images on the display screen based on intensity inputs, while the color calibration sensor provides values responsive to the chromaticity and luminance of a test patch. The CPU performs calibration of the VDT, ensuring that the bias of each color channel is set to reduce differences between target black points and test patches.
