Gimmick expresion medium producing method and data processing method for gimmick expression medium

2:

• The gimmick expression medium producing method according to claim 1, wherein the light-transmission layer of the printing medium is a layer which black-reflects under reflection light.

3:

• The gimmick expression medium producing method according to claim 1, further comprising a step of forming, between the reflection picture and the gimmick print layer, a spoiler-preventing zone which black-reflects under reflection light.

4:

• The gimmick expression medium producing method according to claim 1, wherein the light which passes though the light-transmission layer is obtained by any one of ultraviolet light-emitting body, phosphorescence body, solvatochromic fluorescent dye, stress luminous body, retroreflective medium and natural solar light.

6:

• The gimmick expression medium producing method according to claim 5, wherein the light-transmission layer of the printing medium is a layer which black-reflects under reflection light.

7:

• The gimmick expression medium producing method according to claim 5, further comprising a step of forming, between the reflection picture and the gimmick print layer, a spoiler-preventing zone which black-reflects under reflection light.

8:

• The gimmick expression medium producing method according to claim 5, wherein the luminous ink includes any one of ultraviolet light-emitting body, phosphorescence body, solvatochromic fluorescent dye and stress luminous body.

9:

• A data processing method for printing a gimmick expression medium to print a printing layer which produces a gimmick effect for a printing medium, wherein
• when print data for reflection picture print to form a reflection picture on a light-blocking layer which partially covers the printing medium, and gimmick print data for gimmick print to produce the gimmick effect are formed,
• the print data for the reflection picture print and the gimmick print data for the gimmick print are combined in adjacent to each other into one common image data using a stripe-shaped or dot-shaped lattice pattern to form print data, and the reflection picture print and the gimmick print are carried out by one step (one-pass) using a same printer.

10:

• The data processing method for the gimmick expression medium according to claim 9, wherein print data is formed, and in the print data, a spoiler-preventing zone which black-reflects under reflection light is provided between the reflection picture and the gimmick print.

11:

• The data processing method for the gimmick expression medium according to claim 9, wherein a gimmick print step and a reflection picture print step are print data for a same inkjet printing step.
