Abstract
Provided is an inkjet printing apparatus, an inkjet printing method, and a storage medium capable of causing less density unevenness. To this end, in a case where an expected pause time is larger than a predetermined threshold T (s), a platen air blowing unit blows air to the surface of a printing medium on a platen at a wind speed lower than that during printing.
Claims18
A printing apparatus comprising:
- a printing unit configured to perform printing operation by ejecting a liquid onto a printing medium;
- a support unit configured to support the printing medium to be printed by the printing unit;
- a roller configured to convey the printing medium in a conveyance direction toward the support unit;
- a blowing unit, provided upstream of the printing unit in the conveyance direction, configured to blow air onto the printing medium supported by the support unit in a state where the printing operation is performed by the printing unit;
- and
- a control unit configured to perform control such that
- the air is blown at a first speed in a case where an interruption time during which the printing operation is interrupted before completion of the printing operation is a first time, and
- the air is blown at a second speed which is faster than the first speed in a case where the interruption time is a second time which is shorter than the first time.
A printing method for controlling a printing apparatus including a printing unit configured to perform printing operation by ejecting a liquid to onto a printing medium, a support unit configured to support the printing medium to be printed by the printing unit, a roller configured to convey the printing medium in a conveyance direction toward the support unit, and a blowing, provided upstream of the printing unit in the conveyance direction, configured to blow air onto the printing medium supported by the support unit, the printing method comprising:
- performing the printing operation;
- blowing the air at a first speed in a case where an interruption time during which the printing operation is interrupted before completion of the printing operation is a first time;
- and
- blowing the air at a second speed which is faster than the first speed in a case where the interruption time is a second time which is shorter than the first time.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a printing method for controlling a printing apparatus including a printing unit configured to perform printing operation by ejecting a liquid onto a printing medium, a support unit configured to support the printing medium to be printed by the printing unit, a roller configured to convey the printing medium in a conveyance direction toward the support unit, and a blowing unit, provided upstream of the printing unit in the conveyance direction, configured to blow air onto the printing medium supported by the support unit, the printing method comprising:
- performing the printing operation;
- blowing the air at a first speed in a case where an interruption time during which the printing operation is interrupted before completion of the printing operation is a first time;
- and
- blowing the air at a second speed which is faster than the first speed in a case where the interruption time is a second time which is shorter than the first time.
