Method for preparing proof for plate printing, and recording medium

Abstract

A method for preparing a proof for plate printing, which comprises applying inkjet printing to an ink receiving layer of a recording medium having the ink receiving layer formed on the surface of a support made of plate printing paper for regular printing or made of paper having substantially the same brightness and glossiness as such plate printing paper, to obtain a printing proof.

What is claimed is:  
     
         1 . A method for preparing a proof for plate printing, which comprises applying inkjet printing to an ink receiving layer of a recording medium having the ink receiving layer formed on the surface of a support made of plate printing paper for regular printing or made of paper having substantially the same brightness and glossiness as such plate printing paper, to obtain a printing proof.  
     
     
         2 . The method for preparing a proof for plate printing according to    claim 1   , wherein the ink receiving layer comprises a pigment and a binder.  
     
     
         3 . The method for preparing a proof for plate printing according to    claim 1   , wherein the ink receiving layer contains a water-soluble resin in an amount of at least 80 mass %.  
     
     
         4 . The method for preparing a proof for plate printing according to    claim 1   , wherein the ink receiving layer has a haze of at most 40% and a thickness of from 5 to 100 μm.  
     
     
         5 . The method for preparing a proof for plate printing according to    claim 2   , wherein the ink receiving layer has a haze of at most 40% and a thickness of from 5 to 100 μm.  
     
     
         6 . The method for preparing a proof for plate printing according to    claim 3   , wherein the ink receiving layer has a haze of at most 40% and a thickness of from 5 to 100 μm.  
     
     
         7 . The method for preparing a proof for plate printing according to    claim 2   , wherein the ink receiving layer has an average pore radius of from 3 to 25 nm and a pore volume of from 0.3 to 2.0 cm 3 /g.  
     
     
         8 . A recording medium for a plate printing proof, which comprises a support made of plate printing paper for regular printing or made of paper having substantially the same brightness and glossiness as such plate printing paper, and an ink receiving layer formed on the surface of the support.  
     
     
         9 . The recording medium for a plate printing proof according to    claim 8   , wherein the ink receiving layer comprises a pigment and a binder.  
     
     
         10 . The recording medium for a plate printing proof according to    claim 8   , wherein the ink receiving layer contains a water-soluble resin in an amount of at least 80 mass %.  
     
     
         11 . The recording medium for a plate printing proof according to    claim 8   , wherein the ink receiving layer has a haze of at most 40% and a thickness of from 5 to 100 μm.  
     
     
         12 . The recording medium for a plate printing proof according to    claim 9   , wherein the ink receiving layer has a haze of at most 40% and a thickness of from 5 to 100 μm.  
     
     
         13 . The recording medium for a plate printing proof according to    claim 10   , wherein the ink receiving layer has a haze of at most 40% and a thickness of from 5 to 100 μm.
