1. A method for producing a digitally printed decorative coating on a solid surface, comprising the steps of:
applying solid pigment dye to the surface and treating the coating such that the treatment results in the settinghardening of the coating,
wherein
first, the dry surface is evenly coated la applying solid pigment dye at least over the surface portion where the coating is to be applied,
in a subsequent printing operation liquid is applied to the surface coated with dry pigment dye, thereby temporarily fixing the solid pigment dye to the printed-on surface portions, and
before performing the treatment resulting in the settinghardening of the coating, the non-fixed portion of the solid pigment dye is removed from the surface.
2. The method according to claim 1, wherein a liquid free from solid materials is utilized for the printing operation.
3. The method according to claim 1, wherein distilled water is utilized as a liquid for the printing operation.
4. The method according to claim 1, wherein the resulting color intensity is adjusted by adjusting the thickness of the pigment dye coating applied to the surface.
5. The method according to claim 1, wherein the dry pigment dye coating is applied to the surface by electrostatic powder spraying.
6. The method according to claim 1, wherein for the electrostatic powder spraying operation, the dry pigment dye is conveyed to the vicinity of the target surface applying compressed air.
7. The method according to claim 1, wherein a digitally prepared image is printed on the surface applying the liquid.
8. The method according to claim 1, wherein a layer soluble by the liquid is formed on the surface of the dry pigment dye particles, and the solid pigment is temporarily fixed to the surface portions utilizing a solution made from the soluble layer during the liquid printing operation.
9. The method according to claim 1, wherein the surface is subjected to drying before the treatment resulting in the settinghardening thereof.
10. The method according to claim 1, wherein the liquid is conveyed to the surface utilizing an inkjet printer.
11. The method according to claim 1, wherein dry pigment dye powder particles that have not been fixed to the surface are removed by air blowing, the removed excess powder being returned to the feeder container.
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 jig for aligning a door hinge into a position at a predetermined mounting angle, in an automatic system that automatically mounts door hinges to upper and lower seats on pillars of a vehicle body conveyed by a conveying unit, the jig comprising:

a pair of second support parts movably disposed at both sides of the first support part for respectively supporting both sides of a door bracket of the door hinge;
actuating cylinders fixed to the support frame and connected with the second support parts; and
a clamper fixed to the support frame for clamping the hinge bracket by operation of a clamping cylinder.
2. The jig of claim 1, wherein a pair of guide members for guiding both sides of the hinge bracket is included in the first support part.
3. The jig of claim 2, wherein at least one tooling pin for aligning the hinge bracket is formed at the first support part.
4. The jig of claim 3, wherein an approach sensor configured to sense whether the hinge bracket is seated is included in the first support part.
5. The jig of claim 1, wherein each of the second support parts includes:
a mounting bracket fixed to an actuating rod of the actuating cylinder; and
a pair of guide plates facing each other at a predetermined distance and fixed to the mounting bracket, wherein the pair of guide plates is configured for fixing the respective side of the door bracket and for arranging the door hinge into the position at the predetermined mounting angle.
6. The jig of claim 5, wherein upper portions of the pair of guide plates are smoothly curved away from each other.
7. A jig for aligning a door hinge into a position, in an automatic system that automatically mounts door hinges to upper and lower seats on pillars of a vehicle body conveyed by a conveying unit, the jig comprising:
a support frame;
a base member fixed to the support frame for supporting a hinge bracket of the door hinge;
a pair of supporting members disposed on the support frame to be movable toward or away from each other at both sides of the door hinge, and respectively supporting both sides of a door bracket of the door hinge;
actuating cylinders fixed to the base member and for connected with the supporting members; and for
a clamper fixed to the support frame for clamping the hinge bracket.
8. The jig of claim 7, wherein a seating groove where to seat the hinge bracket of the door hinge is formed on the base member.
9. The jig of claim 7, wherein fixing for grooves fixing the both sides of the door bracket are formed at the supporting members, respectively.
