Abstract:
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.
