Printing method and printed product

Abstract

The object is to obtain a printed product excellent in fastness to washing. To achieve the object, a printing method is provided. The printing method includes a forming step of forming a solvent UV ink layer ( 2 ) on a printing target object ( 1 ), a drying step of drying the solvent UV ink layer ( 2 ), a decorating step of forming a decorative layer ( 3 ) on the dried solvent UV ink layer ( 2 ), and a curing step of curing the decorated solvent UV ink layer ( 2 ) by irradiating the same with ultraviolet.

1 . A printing method, comprising:
 a forming step of forming a solvent UV ink layer on a printing target object;   a drying step of drying the solvent UV ink layer;   a decorating step of adhering a decorative material to the dried solvent UV ink layer or forming a decorative layer containing the decorative material on the dried solvent UV ink layer; and   a curing step of curing the decorated solvent UV ink layer by ultraviolet irradiation.   
     
     
         2 . The printing method according to  claim 1 , wherein
 in the drying step,   the solvent UV ink layer is preheated at a temperature equal to or higher than 40° C. and equal to or lower than 60° C.,   the preheated solvent UV ink layer is heated at a temperature equal to or higher than 35° C. and equal to or lower than 55° C., and   the heated solvent UV ink layer is post-heated at a temperature equal to or higher than 40° C. and equal to or lower than 60° C.   
     
     
         3 . The printing method according to  claim 1 , wherein
 in the forming step,   the solvent UV ink layer is formed by using a solvent UV ink which contains a resin of UV curing type and an organic solvent selected from a group consisting of ketones, alcohols, ethers, hydrocarbons, glycols, glycol ether acetates, glycol ethers, esters, and pyrrolidones.   
     
     
         4 . The printing method according to  claim 3 , wherein
 the solvent UV ink contains the organic solvent by a weight percent equal to or greater than 50 wt. % and equal to or less than 99 wt. % of a total quantity of an ink composition.   
     
     
         5 . The printing method according to  claim 1 , wherein
 the printing target object is fabric.   
     
     
         6 . A printed product, comprising:
 a solvent UV ink layer formed on a printing target object, wherein   a decorative material is adhered to the solvent UV ink layer or a decorative layer containing the decorative material is formed on the solvent UV ink layer.   
     
     
         7 . The printing method according to  claim 2 , wherein
 in the forming step,   the solvent UV ink layer is formed by using a solvent UV ink which contains a resin of UV curing type and an organic solvent selected from a group consisting of ketones, alcohols, ethers, hydrocarbons, glycols, glycol ether acetates, glycol ethers, esters, and pyrrolidones.   
     
     
         8 . The printing method according to  claim 7 , wherein
 the solvent UV ink contains the organic solvent by a weight percent equal to or greater than 50 wt. % and equal to or less than 99 wt. % of a total quantity of an ink composition.
