PURPOSE: To measure the printing pressure over the entire length of a platen by laminating a first color coupler-filled microcapsule layer, a second color coupler-filled microcapsule layer and a third color coupler-filled microcapsule layer on a white polyester film. CONSTITUTION: A first layer 1a, a second layer 1 and a third layer 3c are sequentially laminated on a white polyester film 1 to form a printing pressure measuring sheet 7. More particularly, the layer 1 is obtained by laminating a transparent polyethylene film 4a on the dispersed layer of blue color coupler- filled microcapsules 2a on developer 3a. The layer 1 is obtained by laminating a transparent polyethylene film 4b on the dispersed layer of red color coupler- filled microcapsules 2b on developer 3b. The layer 1 is obtained by laminating a transparent polyethylene film 4c on the dispersed layer of yellow color coupler-filled microcapsules 1c on developer 3c. |
