1. A method for calibrating an image capture system arranged to capture images from a ribbon of a thermal transfer printer, comprising:
determining a first characteristic of an image capture system, the first characteristic comprising a spatial distribution of radiation intensity with a first part and a second part corresponding to respective first and second regions of an imaging location of the image capture system, wherein the ribbon is not positioned in the first and second regions when determining the first characteristic;
obtaining a second characteristic of the image capture system, the second characteristic comprising a modified spatial distribution of radiation intensity with a first part and a second part corresponding to the respective first and second regions of the imaging location, wherein the ribbon is positioned in the first region when obtaining the second characteristic; and
adjusting the second part of the second characteristic based upon the second part of the first characteristic and a relationship between the first part of the second characteristic and the first part of the first characteristic.
