Latest Patents
Among his latest patents are methods for applying ink and washing up after printing. In a printing system where ink from an applicator roller is applied to a form roller in rotational contact with a plate cylinder, these methods involve disengaging the form roller from the plate cylinder. A subtractive roller system is utilized to remove a mixture of residual ink and ink solvent from both the form roller and applicator roller. In preferred embodiments, the press drive is stopped during wash-up, allowing the form roller to be independently driven. Another significant patent involves inking systems for printing presses. This system includes a single form roller for applying ink to a printing cylinder, where ink is applied by an applicator roller featuring an array of interconnected wells and a variable speed drive. The form roller and plate cylinder rotate at the same RPM, while the speed of the applicator roller is varied to control the amount of ink applied to the plate. A variable speed subtractive roller system is also included to remove excess ink and return it to a common reservoir. For wash-up, the press drive and form roller are disengaged, and the inking system is rotated by an inker roller drive while wash-up fluid is applied.
