Inkjet printable flexography substrate and method of using |
摘要 |
A flexography substrate for making I-plates with liquid photopolymers has, in addition to the tie-coat applied to one side to hold the photopolymers in place on the substrate, a micro-porous coating applied to the other side, enabling a masking image to be applied to it using an inkjet printer. In this way, one single sheet of film performs the dual role of substrate and I-plate masking film. By eliminating a sheet of film, the invention provides cost, quality, and environmental benefits. |

1. A method of making a flexographic I-plate from a layer of liquid photopolymer, comprising the steps of:
a. applying a tie-coat to one side of a flexible backing layer of photo-transmissive material; b. applying an inkjet-receptive coating to the other side of the flexible backing layer; c. printing a masking image on the inkjet-receptive coating; d. establishing a layer of liquid photopolymer by casting liquid photopolymer over a relief image negative film, the layer having a lower surface and an upper surface; e. placing the tie-coat side of the flexible backing layer in contact with the upper surface of the liquid photopolymer layer forming a laminate; f. shining polymerizing light through the laminate for a first amount of time to form polymerized island floor areas in the liquid photopolymer in contact with the tie-coat; and g. shining polymerizing light through the relief image negative for a second amount of time to form a polymerized relief image in the liquid photopolymer between the polymerized island floor areas and the relief image negative. |
