IPC: B41J2/325
Filed: 1984-10-19
Abstract: PURPOSE:To increase tonal numbers with an adequate level width by controlling the number of matrix elements to transfer ink by using a system to control the number of heating elements for setting the temperature of each heating element to a high or low temperature, correspondingly to matrix elements according to the density of picture elements. CONSTITUTION:Heating elements 2 of a square from having a side length l1 are arranged in a row sideways in a thermal head 1. and an ink sheet 3 is set in the face of the head 1. On the ink sheet 3, a high-melting ink 4 and a low-melting ink 5 are alternately coated with a smaller repeating unit l2 than the side length l1. The state of transference of only the low-melting ink 5 to only one matrix element corresponds with a tonal level 1. The tonal level is increased one by one each time elements to transfer both the inks 4 and 4 are increased by one. When both the inks 4 and 5 are transferred over all the elements of the matrix, the tonal level becomes a maximum state, or a solid print state. The state corresponds with a tonal level 8.
