PROBLEM TO BE SOLVED: To provide a method for decorating a concrete block, whereby high density, vivid image with exterior durability is well reproducibly formed on the surface of the concrete block, and to provide a concrete block decorated by the same method.SOLUTION: The method for decorating a concrete block includes a process to apply ink on the concrete block using the inkjet method, whereby photo-curable ink of 0% to 7% in cure shrinkage is injected from a nozzle at 5 mPa s to 15 mPa s in viscosity and characteristically, the injected ink is controlled to have the viscosity of 20 mPa s or greater immediately after injected. |
