Abstract
In a colorimetric apparatus including a support base configured to support a colorimetric object, a carriage including a detection unit configured to detect a detection target portion formed at the colorimetric object, the carriage supporting a colorimeter, and a movement unit configured to move the carriage, an adjustment value is calculated based on a detection position of the detection unit where the detection unit is caused to detect a detection target portion and a color measurement position of the colorimeter where the colorimeter is caused to measure a color of the detection target portion, and a position of the carriage at the time when a color of a patch is measured is adjusted based on the adjustment value.
Claims15
A colorimetric apparatus to which a colorimeter configured to measure a color of a patch formed at a colorimetric chart is attachable, the colorimetric apparatus comprising:
- a support base configured to support a colorimetric object, which includes the colorimetric chart;
- a carriage including a detection unit configured to detect a detection target portion formed at the colorimetric object, the carriage supporting the colorimeter;
- a movement unit configured to move the carriage on the support base;
- and
- a control unit, wherein
- the control unit causes the detection unit to detect the detection target portion and specifies a first position, which is a detection position of the detection unit, causes the colorimeter to measure a color of the detection target portion and specifies a second position, which is a color measurement position of the colorimeter, calculates an adjustment value based on the first position and the second position, and adjusts, based on the adjustment value, a position of the carriage at a time when the color of the patch is measured.
An adjustment method for adjusting a color measurement position of a colorimeter with respect to a detection position of a detection unit in a colorimetric apparatus to which the colorimeter configured to measure a color of a patch formed at a colorimetric chart is attachable, the colorimetric apparatus including:
- a support base configured to support a colorimetric object, which includes the colorimetric chart;
- a carriage including a detection unit configured to detect a detection target portion formed at the colorimetric object, the carriage supporting the colorimeter;
- and a movement unit configured to move the carriage on the support base,
- the adjustment method comprising:
- causing the detection unit to detect the detection target portion and specifying a first position, which is a detection position of the detection unit;
- causing the colorimeter to measure a color of the detection target portion and specifying a second position, which is a color measurement position of the colorimeter;
- and
- calculating an adjustment value based on the first position and the second position and adjusting, based on the adjustment value, a position of the carriage at a time when the color of the patch is measured.
