1. A method of multi-station flexographic printing comprising:
printing a first image on a substrate using a first flexographic printing station, wherein the first flexographic printing station includes a first fountain roll, a first flexographic plate, and a first anilox roll for transferring ink from the first fountain roll to the first flexographic plate; and printing a second image on the substrate using a second flexographic printing station, wherein the second flexographic printing station includes a second fountain roll, a second flexographic plate, and a second anilox roll for transferring ink from the second fountain roll to portions of the second flexographic plate, the second anilox roll including:
an ink transfer zone formed on a first portion of a curved contact surface of the second anilox roll; anda low surface energy zone formed on a second portion of the curved contact surface of the second anilox roll, the second portion of the curved contact surface being separate from the first portion of the curved contact surface;wherein the ink transfer zone includes a plurality of cells configured to transfer ink from the second fountain roller to a corresponding portion of the second flexographic plate, andwherein the low surface energy zone comprises a hydrophobic surface with a contact angle of at least 75 degrees and a surface roughness of less than 100 micrometers to inhibit transfer of ink from the fountain roller to a corresponding portion of the second flexographic plate. |
