Claims
- 1. An ink jet recording method which performs recording by attaching liquid droplets of a recording liquid onto a recording medium, comprising the steps of:
- providing an ink jet recording device having a liquid flow path leading to ejection means;
- selecting as said recording liquid a recording liquid having a viscosity of 2 centipoise or higher and a surface tension of 40 dyne/cm or higher, each being measured at 25.degree. C., and said recording liquid containing 50 wt. % or more water and at least one water-soluble organic solvent selected from the group consisting of glycerin, diethylene glycol, triethylene glycol, triethylene glycol monomethyl ether, triethylene glycol monoethyl ether and polyethylene glycol;
- heating said recording liquid so as to reduce the viscosity thereof to below 2 centipoise; and
- thereafter introducing the heated recording liquid having a viscosity of less than 2 centipoise into said liquid flow path upstream of said ejection means.
- 2. An ink jet recording method according to claim 1, wherein the recording medium surface is sized and has fibers exposed thereon.
- 3. An ink jet recording method according to claim 1, wherein said recording liquid comprises a water-soluble dye, a water-soluble organic solvent and water as main components.
- 4. An ink jet recording method according to claim 3, wherein the content of said dye is in the range of from 0.5 to 30 wt. %.
- 5. An ink jet recording method according to claim 3, wherein the content of said organic solvent is in the range of from 2 to less than 50 wt. %.
- 6. An ink jet recording method according to claim 1, wherein the content of water in said recording liquid is 60 wt. % or more.
- 7. An ink jet recording method according to claim 1, wherein the content of water in said recording liquid is 70 wt. % or more.
- 8. An ink jet recording method according to claim 1, wherein the recording liquid is maintained at such a temperature that its viscosity becomes 1.8 centipoise or less.
- 9. An ink jet recording method according to claim 1, wherein the recording liquid is maintained at the range of from 30.degree. to 80.degree. C.
- 10. An ink jet recording method according to claim 1, wherein the recording liquid has a viscosity of 15 centipoise or less at 25.degree. C.
- 11. An ink jet recording method according to claim 1, wherein the recording liquid has a viscosity of 10 centipoise or less at 25.degree. C.
- 12. An ink jet recording method according to claim 1, wherein the recording liquid has a viscosity of 5 centipoise or less at 25.degree. C.
- 13. An ink jet recording method which performs recording by imparting heat energy in response to recording signals to a recording liquid to form liquid droplets thereof, and attaching the liquid droplets onto a recording medium, comprising the steps of:
- providing an ink jet recording device having a liquid flow path leading to ejection means;
- selecting as said recording liquid a recording liquid having a viscosity of 2 centipoise or higher and a surface tension of 40 dyne/cm or higher, each being measured at 25.degree. C., and said recording liquid containing 50 wt. % or more of water, and at least one water-soluble organic solvent selected from the group consisting of glycerin, diethylene glycol, triethylene glycol, triethylene glycol monomethyl ether, triethylene glycol monoethyl ether, and polyethylene glycol;
- heating said recording liquid so as to reduce the viscosity thereof to below 2 centipoise; and
- thereafter introducing the heated recording liquid having a viscosity of less than 2 centipoise into said liquid flow path upstream of said ejection means.
- 14. An ink jet recording method according to claim 13, wherein said recording medium is coated paper.
- 15. An ink jet recording method according to claim 13, wherein said recording liquid comprises a water-soluble dye, a water-soluble organic solvent and water as main components.
- 16. An ink jet recording method according to claim 15, wherein the content of said dye is in the range of from 0.5 to 30 wt. %.
- 17. An ink jet recording method according to claim 15, wherein the content of said organic solvent is in the range of from 2 to less than 50 wt. %.
- 18. An ink jet recording method according to claim 13, wherein the recording liquid is maintained at such a temperature that its viscosity becomes 1.8 centipoise or less.
- 19. An ink jet recording method according to claim 13, wherein the recording liquid is maintained at the range of from 30.degree. to 80.degree. C.
- 20. An ink jet recording method according to claim 13, wherein the recording liquid has a viscosity of 15 centipoise or less at 25.degree. C.
- 21. An ink jet recording method according to claim 13, wherein the recording liquid has a viscosity of 10 centipoise or less at 25.degree. C.
- 22. An ink jet recording method according to claim 13, wherein the recording liquid has a viscosity of 5 centipoise or less at 25.degree. C.
- 23. An ink jet recording method according to claim 1, wherein said recording medium is coated paper.
