1. An ink jet recording apparatus performing recording by discharging an ink composition onto a recording medium, the apparatus comprising:
an ink jet head including a pressure-generating chamber containing an ink composition and applying a discharge pressure to the ink composition, a discharge port from which the ink composition is discharged, and a communicating path for communicating between the pressure-generating chamber and the discharge port, wherein
the ink composition is discharged from the discharge port at a discharge rate of 5 msec or more and 15 msec or less;
the communicating path has a length of 40 \u03bcm or more and 600 \u03bcm or less; and
the ink composition contains a self-dispersible pigment and an organic solvent having a Hansen solubility parameter of 14 (calcm3)12 or more and 16 (calcm3)12 or less.
2. The ink jet recording apparatus according to claim 1, wherein the apparatus has a discharge port resolution per unit length of the recording head of 200 dpi or more.
3. An ink jet recording method using an ink jet recording apparatus according to claim 2.
4. The ink jet recording apparatus according to claim 1, wherein the pigment is a self-dispersible pigment having a carboxyl group on the surface.
5. An ink jet recording method using an ink jet recording apparatus according to claim 4.
6. The ink jet recording apparatus according to claim 1, wherein
the apparatus includes a scanning mechanism for moving the ink jet head and a transporting mechanism for moving the recording medium;
the scanning mechanism moves the ink jet head so as to perform scanning and thereby forms a recording discharge region onto which the ink composition is discharged and moves the ink jet head to a region outside the recording discharge region and thereby forms a non-recording discharge region onto which the ink composition is discharged;
the transporting mechanism transports the recording medium to the recording discharge region and moves the recording medium in a direction crossing the extending direction of the recording discharge region; and
a recorded image has a recording resolution of 200 dpi or more in the direction of movement of the recording medium by the transporting mechanism.
7. The ink jet recording apparatus according to claim 6, wherein the recording discharge region has a length of 60 cm or more.
8. An ink jet recording method using an ink jet recording apparatus according to claim 7.
9. The ink jet recording apparatus according to claim 6, wherein
the ink jet head includes a piezoelectric element that fluctuates the capacity of the pressure-generating chamber; and
the piezoelectric element is driven with a driving potential difference of 10 V or more and 30 V or less.
10. An ink jet recording method using an ink jet recording apparatus according to claim 9.
11. The ink jet recording apparatus according to claim 6, wherein the ink composition contains the pigment in a content of 2% by mass or more and 8% by mass or less.
12. An ink jet recording method using an ink jet recording apparatus according to claim 11.
13. The ink jet recording apparatus according to claim 6, wherein the ink jet head discharges the ink composition from the discharge ports onto the non-recording discharge region and discharges the ink composition from the same discharge ports onto the non-recording discharge region again within a time interval of 1.5 seconds or more and 6.0 seconds or less.
14. An ink jet recording method using an ink jet recording apparatus according to claim 13.
15. The ink jet recording apparatus according to claim 6, wherein the piezoelectric element during the time in which the ink is not discharged is driven with a voltage having a potential difference that does not allow the ink composition to be discharged.
16. An ink jet recording method using an ink jet recording apparatus according to claim 15.
17. The ink jet recording apparatus according to claim 6, wherein the organic solvent is a lactam or a polyhydric alcohol.
18. An ink jet recording method using an ink jet recording apparatus according to claim 17.
19. An ink jet recording method using an ink jet recording apparatus according to claim 6.
20. An ink jet recording method using an ink jet recording apparatus according to claim 1.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for creating a textured surface on a breast implant, the method comprising:
providing a breast implant shell;
applying a tacky layer on the shell;
using a computer-controlled deposit mechanism to deposit a texturing material in a predetermined manner onto the tacky layer;
removing the texturing material from the tacky layer to obtain a textured surface.
2. The method of claim 1 wherein the step of using a computer-controlled deposit mechanism comprises
depositing onto the tacky layer a predetermined number of successive layers of the texturing material; and
applying to one or more predetermined regions of each successive layer of texturing material a binder that will cause the texturing material to become bonded at said one or more predetermined regions.
3. The method of claim 1 wherein the texturing material is a sugar.
4. The method of claim 1 wherein the texturing material is a sugar and the binder is an aqueous solution or alcohol.
5. The method of claim 1 further comprising applying an additional layer to the deposited layers of texturing material.
6. The method of claim 5 further comprising using a computer-controlled deposit mechanism to deposit another layer of texturing material in a predetermined manner onto the additional layer.
7. A method for creating a textured surface on a breast implant, the method comprising:
providing a breast implant shell;
applying a tacky silicone layer on the shell;
using a computer-controlled deposit mechanism to deposit a texturing material in a predetermined manner and in a predetermined pattern onto the tacky silicone layer, the predetermined pattern being a model pattern stored in a CAD format; and
removing the texturing material from the tacky silicone layer to obtain a textured surface.
