Printer and medium
View Patent ↗According to one embodiment, a printer includes a conveying mechanism, a first image forming unit, and a second image forming unit. The conveying mechanism conveys a medium. The first image forming unit forms an image with a non-temperature-sensitive ink whose color is not changed depending on a temperature, on the medium. The second image forming unit forms an image with a temperature-sensitive ink whose color is changed depending on a temperature, on the medium having the image with the non-temperature-sensitive ink formed thereon.
1. A printer, comprising:
a conveying mechanism configured to convey a medium;
a first image forming unit configured to form an image with a non-temperature-sensitive ink whose color is not changed depending on a temperature, on the medium; and
a second image forming unit configured to form an image with a temperature-sensitive ink whose color is changed depending on a temperature, on the medium having the image with the non-temperature-sensitive ink formed thereon.
2. The printer of claim 1 , wherein the second image forming unit is configured to form the image with the temperature-sensitive ink in such a state as to cover at least a portion of the image with the non-temperature-sensitive ink.
3. The printer of claim 2 , wherein the image with the temperature-sensitive ink has a property of transmitting visible rays.
4. The printer of claim 1 , wherein the second image forming unit is configured to form, as the image with the temperature-sensitive ink, an image which is visualized when a specified temperature condition is not satisfied.
5. The printer of claim 1 , further comprising:
a coloring conversion mechanism configured to convert a coloring state of the image with the temperature-sensitive ink by heating or cooling the image with the temperature-sensitive ink.
6. A printer, comprising:
a first ink ribbon holding unit configured to hold an ink ribbon applied with a non-temperature-sensitive ink whose color is not changed depending on a temperature;
a first conveying unit configured to convey the ink ribbon held by the first ink ribbon holding unit;
a first thermal head configured to heat the non-temperature-sensitive ink and form an image with the non-temperature-sensitive ink on a medium;
a second ink ribbon holding unit configured to hold an ink ribbon applied with a temperature-sensitive ink whose color is changed depending on a temperature;
a second conveying unit configured to convey the ink ribbon held by the second ink ribbon holding unit; and
a second thermal head configured to heat the temperature-sensitive ink and form an image with the temperature-sensitive ink on the medium having the image with the non-temperature-sensitive ink formed thereon.
7. A printing method, comprising:
conveying a medium through a conveyance path by a conveying mechanism;
forming an image with a non-temperature sensitive ink whose color is not changed depending on a temperature, on the medium; and
forming an image with a temperature-sensitive ink whose color is changed depending on a temperature, on the medium having the image with the non-temperature-sensitive ink formed thereon.
8. The method of claim 7 , wherein the image with the temperature-sensitive ink is formed in such a state as to cover at least a portion of the image with the non-temperature-sensitive ink.
9. The method of claim 7 , wherein the image with the temperature-sensitive ink is formed to be visualized when a specified temperature condition is not satisfied.
10. The method of claim 7 , further comprising:
converting a coloring state of the image with the temperature-sensitive ink by heating or cooling the image with the temperature-sensitive ink.
