Abstract

A method for manufacturing a dye-attached substrate provided with a dye section that includes a sublimable dye to be deposited on a resin body includes a printing step of printing a plurality of units of the dye sections, the dye section for dyeing one resin body or one set of resin bodies constituting one unit, lined up in a longitudinal direction of a long thin substrate, by discharging ink that includes the sublimable dye on the substrate using a printing device, a piece creating step of creating a piece of the substrate that includes the plurality of units of the dye sections, by cutting the substrate on which the dye section is printed, and a drying step of drying the ink of the plurality of units of the dye sections included in the piece of the substrate.

First claim

What is claimed is:

1. A method for manufacturing a dyed resin body using a dye-attached substrate provided with a dye section that includes a sublimable dye to be deposited on a resin body, the method comprising:
printing a plurality of units of the dye sections, each dye section for dyeing one resin body or one set of resin bodies constituting one unit, lined up in a longitudinal direction of a long thin substrate, by discharging ink that includes the sublimable dye on the substrate using a printing device, wherein the resin body is a lens,
creating a piece of the substrate that includes the plurality of units of the dye sections, by cutting the substrate on which the dye section is printed;
drying the ink of the plurality of units of the dye sections included in the piece of the substrate;
heating the sublimable dye, the sublimable dye subliming toward the resin body and being deposited on the resin body after the sublimable dye is heated; and
heating the resin body on which the sublimable dye has been deposited, the sublimable dye being fixed to the resin body after the resin body is heated.

2. The method according to claim 1 , wherein
the substrate is cut by a cutter included in the printing device.

3. The method according to claim 2 , wherein
the printing of the plurality of units of the dye sections and the creating of the piece of the substrate are alternately executed by the printing device.

4. The method according to claim 1 , further comprising:
creating the substrate that includes one of the units of the dye sections, by further cutting the piece of the substrate on which the ink is dried.

5. The method according to claim 1 , further comprising:
inputting a command for selecting the number of units of the dye sections to be included in one piece of the substrate, within a range equal to or less than a predetermined upper limit; and
printing the selected number of units of the dye sections on the substrate by the printing device.
