Latest Patents

Xiang Jun Liu holds a patent titled "Wet-trapping of energy curable flexographic inks and coatings." This patent presents methods and apparatus for flexographic color printing, focusing on implementing 'wet trapping' in flexographic printing using energy curable liquid inks. The invention allows for the formulation of radiation curable inks that can wet trap over each other without back-trapping onto the plates and anilox units of down-line printing units. By controlling the storage modulus of the ink coating, the highest G' ink is printed first, with successive colors trapped in the order of their declining G' values. This innovative approach enables an image in wet ink to be trapped over a different image in wet ink of a different color without redepositing the first ink onto subsequent plates and rollers in the printing press.
