Claims
- 1. A recording apparatus comprising:
- depositing means for depositing a recording agent on a medium; and
- control means for controlling said depositing means such that said recording agent is deposited at substantially the same position on said medium a plurality of times and a time interval between each deposition of said recording agent at the same position is changed to control a concentration of said recording agent deposited at said same position a plurality of times.
- 2. An apparatus according to claim 1, wherein said depositing means includes means for depositing ink onto paper.
- 3. An apparatus according to claim 1, further comprising supply means for supplying image data to said depositing means.
- 4. An apparatus according to claim 3, further comprising discriminating means for discriminating characteristics of said image data, wherein said control means controls the interval between depositions of said recording agent in accordance with the result of said discrimination of said discriminating means.
- 5. An apparatus according to claim 1, wherein said control means has a first control mode in which said interval between depositions of said recording agent causes a change in size of a dot formed on said medium by said recording agent when said recording agent is deposited at substantially the same position on said medium a plurality of times, and a second control mode in which said interval between depositions of said recording agent does not cause a change in the size of said dot.
- 6. An apparatus according to claim 5, wherein in said second control mode, said interval between depositions of said recording agent is sufficient to permit said recording agent to permeate said medium after each said deposition prior to the subsequent said deposition.
- 7. A recording method comprising:
- a first step of depositing a recording agent at a predetermined position on a medium; and
- a second step of depositing said recording agent at said predetermined position at a predetermined time interval after said first step such that a dot formed at said predetermined position by succeeding depositions in said first and said second steps has the same size as a dot formed at said predetermined position by deposition in said first step.
- 8. A method according to claim 7, wherein the recording agent which is deposited in said first step and the recording agent which is deposited in said second step are the same kind of recording agents.
- 9. A method according to claim 7, further comprising repeating said first and second steps.
- 10. A method according to claim 7, wherein said recording agent is a liquid having a predetermined concentration.
- 11. An apparatus according to claim 10, wherein said medium is a medium into which said liquid permeates.
- 12. A method according to claim 11, wherein said medium is paper.
- 13. A recording method according to claim 7, wherein a dot of an image is reproducible in different colors without changing the size of the dot formed in said first step.
- 14. An apparatus comprising:
- supply means for supplying multi-value image data;
- developing means for developing into binary data said multi-value image data supplied by said supply means;
- depositing means for depositing a recording agent on a medium in accordance with said binary data developed by said developing means; and
- control means for controlling said developing means to develop the same multi-value image data supplied by said supply means into binary data a plurality of times and controlling said depositing means to deposit said recording agent on said medium a plurality of times such that said recording agent is deposited a plurality of times at a predetermined interval in accordance with each binary data developed from the same multi-value image data by said developing means a plurality of times, wherein said developing means includes:
- storing means for storing a plurality of threshold value matrices; and
- comparing means for sequentially comparing the plurality of threshold value matrices store din said storing means with the multi-value image data supplied by said supply means.
- 15. An apparatus according to claim 14, wherein said control means develops said multi-value image data into binary data a plurality of times by using different threshold values.
- 16. An apparatus according to claim 14, wherein said depositing means superposes and deposits the recording agent at the same position on the medium when depositing the recording agent onto the medium in accordance with the binary data developed by said developing means a plurality of times.
- 17. An apparatus according to claim 14, wherein said recording agent is a liquid having a predetermined concentration.
- 18. An apparatus according to claim 17, wherein said medium is a medium into which said liquid permeates.
- 19. An apparatus according to claim 18, wherein said medium is paper.
- 20. A recording method comprising:
- a first step of depositing a recording agent on a medium; and
- a second step of depositing on the medium the same kind of recording agent as said recording agent deposited in said first step after a sufficient time to allow said agent deposited in said first step to permeate into said medium so that a dot formed by succeeding depositions in said first and second steps has the same size as a dot formed by deposition in said first step.
- 21. A method according to claim 20, wherein in said second step said recording agent is deposited at substantially the same position as that on which said recording agent is deposited in said first step.
- 22. A method according to claim 20, further comprising repeating said first and second steps.
- 23. A method according to claim 20, wherein said recording agent is a liquid having a predetermined concentration.
- 24. A method according to claim 23, wherein said medium is a medium into which said liquid permeates.
- 25. A method according to claim 24, wherein said medium is paper.
- 26. A recording method according to claim 20, wherein an image is reproducible in different colors without changing the size of the dot formed in said first step.
