Description

REFERENCE TO RELATED APPLICATIONS This application claims priority from Japanese Patent Application No. 2022-081931 filed May 18, 2022. The entire content of the priority application is incorporated herein by reference. BACKGROUND ART The present disclosure relates to a print device. A print device of known art judges whether or not the print quality of an identification code is acceptable or unacceptable, after the identification code is printed on a label adhered to a long label base sheet. On a label for which the print quality is judged to be unacceptable, the print device prints a shaded image over substantially the whole region of the label, and information indicating a judgment reason. DESCRIPTION The print device of the known art prints the shaded image and the information indicating the judgment reason using a thermal transfer ribbon that is an ink supply source. Thus, in the print device of the known art, due to the printing of the shaded image and the information indicating the judgment reason, a period of time from a start of using the ink supply source to the consumption of the ink supply source becomes shorter, and replacement of the ink supply source becomes more frequent. Embodiments of the broad principles derived herein provide a print device that, compared to known art, suppresses an increase in a replacement frequency of an ink supply source, when printing an image indicating that a print quality is unacceptable. Embodiments provide a print device that includes a print head, a conveyer, a reader, a processor, and a memory. The print head is configured to perform color printing of an image on a predetermined print region of a medium, using inks supplied from a plurality of ink supply sources having mutually different colors of ink. The conveyer is configured to convey the medium in a conveyance direction and in a return direction opposite to the conveyance direction. The reader is provided downstream of the print head in the conveyance direction, and configured to read the image printed in the print region. The processor is configured to control the print head, the conveyer, and the reader. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include print processing of controlling the conveyer and the print head and printing an identification code in the print region, reading processing of, after the print processing, controlling the conveyer and the reader to acquire a read image obtained as a result of the reader reading the identification code printed in the print region, and judgment processing of judging, based on the read image, whether or not a print quality of the identification code satisfies a predetermined standard. The processes include result print processing of, when it is judged in the judgment processing that the print quality does not satisfy the predetermined standard, controlling the conveyer and the print head, to print, in the print region, a VOID image indicating that the predetermined standard is not satisfied, using a color different to a color of the identification code, and at a position at which at least a part of the VOID image overlaps the identification code. When it is judged that the print quality does not satisfy the predetermined standard, compared to a case in which the VOID image is printed using the same color as the color of the identification code, the result print processing of the print device contributes to suppressing an increase in a replacement frequency of an ink supply source supplying the ink used for printing the identification code. Embodiments also provide a print device that includes a print head, a conveyer, a reader, a processor, and a memory. The print head is configured to perform color printing of an image on a predetermined print region of a medium, using inks supplied from a plurality of ink supply sources having mutually different colors of ink. The conveyer is configured to convey the medium in a conveyance direction and in a return direction opposite to the conveyance direction. The reader is provided downstream of the print head in the conveyance direction, and configured to read the image printed in the print region. The processor is configured to control the print head, the conveyer, and the reader. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include print processing of controlling the conveyer and the print head and printing an identification code in the print region, reading processing of, after the print processing, controlling the conveyer and the reader to acquire a read image obtained as a result of the reader reading the identification code printed in the print region, and judgment processing of judging, based on the read image, whether or not a print quality of the identification code satisfie
