Abstract
A method for enhancing the color density of printed paper comprising a print enhancing fluid. The print enhancing fluid is applied to the paper prior to ink application in order to enhance the color density of the image printed on the paper. Utilization of the print enhancing fluid of this invention also provides improved printing press hygiene and printing process efficiency especially when printing paper products having high color density images.
Claims23
The method for printing indicia said method comprising the steps of:
- (a) providing a printing press;
- (b) applying a substrate to said printing press, said substrate having a first outer surface and a second outer surface opposed thereto;
- (c) applying from about 1 g/m2 to 50 g/m2 of a print enhancing fluid to at least one of said first outer surface and said second outer surface of said substrate;
- (d) applying indicia to at least one of said first outer surface and said second outer surface of said substrate wherein said indicia is comprised of ink and wherein said ink contacts said print enhancing fluid on at least one of said first outer surface or one of said second outer surface of said substrate said indicia including a color density whereby said color density of said indicia is enhanced.
The method of claim 2 wherein said printing press is a flexographic printing press having at least one print station.
The method for printing indicia, said method comprising the steps of:
- (a) providing a substrate having a first outer surface and a second outer surface opposed thereto;
- (b) applying from about 1 g/m2 to 50 g/m2 of a print enhancing fluid to at least one of said first outer surface and said second outer surface of said substrate;
- (c) applying indicia to at least one of said first outer surface and said second outer surface of said substrate wherein said indicia is comprised of ink and wherein said ink contacts said print enhancing fluid on at least one of said first outer surface or one of said second outer surface of said substrate said indicia including a color density whereby said color density of said indicia is enhanced.
The method for printing indicia, said method comprising the steps of:
- (a) providing a substrate having a first outer surface and a second outer surface opposed thereto;
- (b) applying a print enhancing fluid comprising water, alcohol, oil, or mixtures thereof to at least one of said first outer surface and said second outer surface of said substrate;
- (c) printing an image on at least one of said first outer surface and said second outer surface of said substrate wherein said image is comprised of ink and wherein said ink contacts said print enhancing fluid on at least one of said first outer surface or said second outer surface of said substrate said image including a color density whereby said color density of said image is enhanced.
