ABSTRACT:
Printed images having a half tone are realized in a printing system using a temperature sensitive paper. A thermal-head which is positioned close to the temperature sensitive paper is heated by an input electrical signal and the heated thermal-head changes the darkness of the temperature sensitive paper. The period of time that the thermal-head is heated is controlled by the input electrical signal and, thus, the temperature of the thermal-head is a function of the input electrical signal. The darkness or the concentration of images on the temperature sensitive paper can be changed according to the input electrical signal. Thus an image having a half tone is obtained on a temperature sensitive paper.
