Abstract

A printing device includes a liquid composition having a viscosity of from 2 to 15 mPa·s and a static surface tension of from 20 to 50 mN/m. A liquid composition container contains the liquid composition, a liquid composition applying device is configured to apply the liquid composition to a contact-target member, and a contact member is configured to make contact with a region to which the liquid composition has been applied in the contact-target member. The contact member includes a liquid composition holding layer configured to hold the liquid composition, an adhesive layer that fixes the liquid composition holding layer, and a core, in this order from a side that makes contact with the region. The liquid composition holding layer has a thickness of from 200 to 1,300 μm.

First claim

The invention claimed is:

1. A printing device, comprising:
a liquid composition having a viscosity of from 2 to 15 mPa·s and a static surface tension of from 20 to 50 mN/m;
a liquid composition container that contains the liquid composition;
a liquid composition applying device configured to apply the liquid composition to a contact-target member; and
a contact member configured to make contact with a region to which the liquid composition has been applied in the contact-target member,
wherein the contact member comprises a liquid composition holding layer configured to hold the liquid composition, an adhesive layer that fixes the liquid composition holding layer, and a core in this order from a side that makes contact with the region,
wherein the liquid composition holding layer has a thickness of from 200 to 1,300 μm.

2. The printing device according to claim 1 , wherein a contact angle of pure water on the liquid composition holding layer is 120 degrees or more.

3. The printing device according to claim 1 , wherein the liquid composition has a viscosity of from 2 to 10 mPa·s and a static surface tension of from 20 to 35 mN/m.

4. The printing device according to claim 1 , wherein the liquid composition holding layer comprises a fluororesin fiber layer.

5. The printing device according to claim 4 , wherein the fluororesin fiber layer comprises a non-woven fabric.

6. The printing device according to claim 1 , wherein the liquid composition holding layer has a thickness of from 500 to 1,000 μm.

7. The printing device according to claim 1 , wherein a thickness proportion of the adhesive layer to the liquid composition holding layer is from 3 to 50 percent.

8. The printing device according to claim 1 , wherein a thickness proportion of the adhesive layer to the liquid composition holding layer is from 10 to 40 percent.

9. The printing device according to claim 1 , wherein the core has a roller form.

10. The printing device according to claim 9 , wherein the core has a roller form with a diameter of a cross section of the core decreasing from both ends to a center.

11. The printing device according to claim 1 , wherein the contact-target member comprises a recording medium.

12. The printing device according to claim 1 , wherein the printing device conveys the contact-target member at 50 m/minute or more.

13. The printing device according to claim 1 , wherein a length of the contact-target member along a conveying direction is longer than a length of a conveyance path of the contact-target member in the printing device.

14. The printing device according to claim 1 , wherein the contact member is a first member that makes contact with the region.

15. The printing device according to claim 1 , wherein the contact-target member comprises a substrate and an application layer disposed on at least one side of the substrate, wherein transfer amounts of pure water to the contact-target member at a contact time of 100 ms and 400 ms are respectively 2 to 35 mL/m 2 and 3 to 40 mL/m 2 as measured by a dynamic scanning absorptometer.

16. The printing device according to claim 1 , further comprising a liquid composition heating device configured to heat the liquid composition the region that has been applied to the contact-target member from a rear side to a side having the region, wherein the contact member makes contact with the region of the contact-target member after the liquid composition is heated by the liquid composition heating device.

17. A contact member, comprising:
a liquid composition holding layer configured to hold a liquid composition having a viscosity of from 2 to 15 mPa·s and a static surface tension of from 20 to 50 ml m;
an adhesive layer that fixes the liquid composition holding layer; and
a core,
wherein the contact member is configured to make contact with a region to which the liquid composition has been applied in a contact-target member,
wherein the liquid composition holding layer, the adhesive layer, and the core are disposed in this order from a side that makes contact with the region,
wherein the liquid composition holding layer has a thickness of from 200 to 1,300 μm.

18. A drying device, comprising:
a contact member comprising:
a liquid composition holding layer configured to hold a liquid composition having a viscosity of from 2 to 15 mPa·s and a static surface tension of from 20 to 50 mN/m;
an adhesive layer that fixes the liquid composition holding layer; and
a core;

wherein the contact member is configured to make contact with a region to which the liquid composition has been applied in a contact-target member,
wherein the liquid composition holding layer, the adhesive layer, and the core are disposed in this order from a side that makes contact with the region,
wherein the liquid composition holding layer has a thickness of from 200 to 1,300 μm,
wherein the drying device is configured to dry the contact-target member to which the liquid composition has been applied.
