Title: Innovations by Omkar J Natu in Lithographic Printing Technology
Introduction
Omkar J Natu is an accomplished inventor based in Warren, NJ (US). He has made significant contributions to the field of lithographic printing technology, holding 2 patents that showcase his innovative approach to printing surfaces.
Latest Patents
One of his latest patents is for a processless, laser imageable lithographic printing plate. This invention involves a thermal lithographic printing plate that requires no chemical development to remove areas of the imaged plate. The printing plate consists of a sheet substrate, a hydrophilic layer, and a thermally sensitive imaging layer. The hydrophilic layer contains about 30 weight % of an aluminosilicate or clay, and it features a micro-porous exterior surface. The imaging layer is also micro-porous and is exposed imagewise using infrared laser radiation to create an imaged layer. This method allows for digital imaging by infrared laser radiation, making the exposed areas ink receptive while the non-exposed areas repel ink after treatment with a conditioner liquid.
Another notable patent by Natu involves thermal lithographic printing plates that enable direct imaging of a printing surface using infrared radiation. This method eliminates the need for pre- or post-UV-light exposure or heat treatment. The printing plate includes a support with a hydrophilic surface overcoated with an imaging layer that contains various polymers and infrared absorbing compounds. The imaging layer is exposed to infrared radiation to produce exposed image areas, which are then developed with an aqueous alkaline developing solution to form the lithographic printing surface.
