Latest Patents

David H. Knapp holds a patent for a "Selectively Absorbent Mask Printing Process." This innovative printing technique provides a remarkable color tone print characterized by muted contrasts, achieved through the sequential operation of two flexographic print stations. The process utilizes an uncoated white paper substrate, suitable for stationery or envelope grading. In the first print station, an image is printed using a colorless solution of polyol, such as glycerine, in a glycol ether solvent. The second print station applies a uniform color coating of compatible pigment or solvent dye-based ink across the entire web surface. The distinctive printed product emerges due to the variance in ink absorption related to the glycerine solution image areas, resulting in unique shade and tone differences.
