First, step S451 is executed, and the material state monitor 60 obtains the temperature change amount and the first appearance information (or the first hardness information). After step S452 is executed, the material state monitor 60 finds out the temperature change amount and the first appearance information (or the first appearance information). Hardness information) corresponding to the label code 80. After that, step S453 is executed, and the material state monitor 60 determines whether the material 20 is in a normal state or an abnormal state according to the label code 80 .

FIG. 7(B) is a schematic diagram of a detailed flow of step S45 in another embodiment of the present invention, and please refer to FIGS. 1 to 7(A) at the same time. First, step S451 is executed, and the material state monitor 60 obtains the temperature change amount, the first appearance information and the second appearance information (or the temperature change amount, the first hardness information and the second hardness information). After step S452 is executed, the material state monitor 60 finds out the label code 80 corresponding to the temperature change amount, the first appearance information and the second appearance information (or the temperature change amount, the first hardness information and the second hardness information). After that, step S453 is executed, and the material state monitor 60 determines whether the material 20 is in a normal state or an abnormal state according to the label code 80 .

In this way, when the material 20 is in an abnormal state, the material state monitor 60 can immediately notify the user, thereby preventing pirated or wrong-standard materials from being used. In addition, the present invention can also ensure the correctness of the materials of the printing task. For example, when the wrong materials are used, the material detection device 1 can also detect immediately, so as to avoid the failure of the printing task. In addition, this creation is also convenient to use, and users can test materials at any time.
