Abstract
A method is described in which a first color is detected at a user-selected arbitrary position of a first print; a second color is detected at a user-selected arbitrary position of a second print printed by a printer; a color difference between the first color and the second color is determined; and settings of the printer are changed to reduce the color difference in further prints printed by the printer.

Method comprising:
- detecting (102;
- 206) a first color (26a, 26b) at a user-selected arbitrary position (22;
- 22a, 22b) of a first print (12);
- defecting;
- (104;
- 208) a second color (26a′, 26b′) at a user-selected arbitrary position (18;
- 18a, 18b) of a second print (16) printed by a printer (50);
- determining (106;
- 212) a color difference (28a, 28b) between the first color (26a, 26b) and the second color (28a′, 26b′);
- and
- changing (108;
- 214) a setting of the printer (50) to reduce the color difference (28a, 28b) in further prints (16′) printed by the printer (50).

Printer (50) comprising:
- a sensor arrangement (48) to detect a color (26a, 26b, 26a′, 26b′) of a print (12, 16), wherein a position of the sensor arrangement (48) relative to the print (12, 16) is adjustable;
- a user interface (62, 62′) enabling a user to adjust a relative position between the sensor arrangement (48) and the print (12, 16) and to select this relative position as a user-selected arbitrary position (18, 22;
- 22a, 22b;
- 18a, 18b) and
- a controller to;
- determine a color difference (28a, 28b) between a first color (26a, 26b) detected at a user-selected arbitrary position (22;
- 22a, 22b) of a first print (12) and a second color (26a′, 26b′) detected at a user-selected arbitrary position (18;
- 18a, 18b) of a second print (16);
- and to
- change settings of the printer (50) to reduce the color difference (28a, 28b) in further prints (16′) printed by the printer (50).
