Abstract
A printing method includes determining the upper limit of the amount of the ink to be discharged based on a color saturation suppression upper limit, and at least one of an overflowing suppression upper limit, a bleeding suppression upper limit, and an aggregation suppression upper limit. The determining of the upper limit of the amount of the ink to be discharged includes setting in advance priorities among the suppressing of the color saturation of the ink and at least one of the overflowing of the ink, the bleeding of the ink, and the aggregation of the ink, and determining the upper limit of the amount of the ink to be discharged based on the priorities.
Claims13
A printing method for discharging ink onto a printing medium to print an image on the printing medium, the printing method comprising:
- printing on a medium a test pattern for determining an upper limit of an amount of ink to be discharged;
- capturing an image of the medium on which the test pattern has been printed;
- executing color measurement on the medium on which the test pattern has been printed;
- and
- determining the upper limit of the amount of the ink to be discharged based on
- a color saturation suppression upper limit calculated based on color measurement information of the medium obtained by the color measurement, the color saturation suppression upper limit being an upper limit of the amount of the ink to be discharged for suppressing color saturation of the ink, and
- at least one of
- an overflowing suppression upper limit calculated based on imaging information of the medium obtained from the image captured, the overflowing suppression upper limit being an upper limit of the amount of the ink to be discharged for suppressing overflowing of the ink,
- a bleeding suppression upper limit calculated based on the imaging information, the bleeding suppression upper limit being an upper limit of the amount of the ink to be discharged for suppressing bleeding of the ink, and
- an aggregation suppression upper limit calculated based on the imaging information, the aggregation suppression upper limit being an upper limit of the amount of the ink to be discharged for suppressing aggregation of the ink, wherein
- the determining of the upper limit of the amount of the ink to be discharged includes setting in advance priorities among the suppressing of the color saturation of the ink and at least one of the overflowing of the ink, the bleeding of the ink, and the aggregation of the ink, and determining the upper limit of the amount of the ink to be discharged based on the priorities.
An ink discharge amount upper limit determining method for determining an upper limit of an amount of ink to be discharged from a printing apparatus, the ink discharge amount upper limit determining method comprising:
- performing a first suppression upper limit calculation to calculate a color saturation suppression upper limit for suppressing color saturation of the ink based on color measurement information of a test pattern printed by the printing apparatus on a medium;
- performing a second suppression upper limit calculation to calculate at least one of an overflowing suppression upper limit for suppressing overflowing of the ink, a bleeding suppression upper limit for suppressing bleeding of the ink, and an aggregation suppression upper limit for suppressing aggregation of the ink, based on imaging information of the test pattern printed by the printing apparatus on the medium;
- and
- determining the upper limit of the amount of the ink to be discharged from the printing apparatus based on at least one of calculation results from the first suppression upper limit calculation and the second suppression upper limit calculation, wherein
- the determining of the upper limit of the amount of the ink to be discharged from the printing apparatus includes setting in advance priorities among the suppressing of the color saturation of the ink and at least one of the overflowing of the ink, the bleeding of the ink, and the aggregation of the ink, and to determine the upper limit of the amount of the ink to be discharged based on the priorities.
