1. High quality frequency modulated halftoning
Abstract : The fact that most printing devices, such as laser printers, are restricted to very few colors has led to an increased interest in finding efficient techniques that transform a continuoustone image into a binary one. Such techniques are referred to as halftoning methods. READ MORE

2. 2D and 3D Halftoning for Appearance Reproduction
Abstract : The appearance of an object is determined by its chromatic and geometric qualities in its surrounding environment using four optical parameters: color, gloss, translucency, and surface texture. Reconstructing the appearance of objects is of great importance in many applications, including creative industries, packaging, fine-art reproduction, medical simulation, and prosthesis-making.

3. Automated CtP Calibration for Offset Printing : Dot gain compensation, register variation and trapping evaluation
Abstract : Although offset printing has been and still is the most common printing technology for color print productions, its print productions are subject to variations due to environmental and process parameters. Therefore, it is very important to frequently control the print production quality criteria in order to make the process predictable, reproducible and stable. READ MORE

5. Characterization of Halftone Prints based on Microscale Image Analysis
Abstract : Ink spreading and lateral light scattering in the substrate affect the color of a halftone print. One of the most important phenomena which affects the print result is dot gain, meaning that printed dots appear larger than the dots in the digital bitmap. READ MORE
