The print head consists of a ceramic plate with a large number of heated points positioned in a line perpendicular to the feed direction of the paper. When a point is heated, it warms the heat-sensitive top layer of the paper to a temperature above 70 °C which develops a black or blue dot (depends on the type of paper used).
Print speed, number of burn pulses and burn time can be adjusted for optimal print result. See CWT Software Configuration Handbook.
