Method and apparatus for printing |
| abstract |
We describe a method and a printer for printing on thermochromic re-writable surfaces, for example on cards such as Identity Cards. Data relating to an image to be printed onto the surface (which may already have an image printed thereon) is received and processed to identify dark and light pixels in the image. From this processing, a sequence of drive signals are produced to drive a thermal print head to produce the image on the re-writable surface. The thermal print head is driven to print the identified dark pixels in the image as dark pixels. For pixels of the image identified as being light pixels, the thermal print head is driven to erase those corresponding pixels on the surface |
