Therefore, the development of low\u2010cost, irreversible, and tamper\u2011proof temperature indicators is of great practical significance. Based on the acid\u2010catalyzed irreversible ring\u2010opening coloration of crystal violet lactone (CVL) under acidic conditions, a bilayer temperature monitoring label was prepared in this study, and the label structure was further optimized by introducing three\u2010dimensional (3D) printing technology. Upon temperature excursions, the acidic components in the upper layer diffused into the lower layer, triggering an irreversible color change that remained stable after re\u2010cooling. Quantitative color analysis using a smartphone application showed that at 15\u00b0C the hue angle increased linearly with exposure time (correlation coefficient\n                      <jats:italic>r<\/jats:italic>\n                      = 0.9854), demonstrating the feasibility of real\u2010time digital temperature monitoring. To broaden the practical temperature range, an integrated label mold was fabricated via 3D printing, and the monitoring threshold was tuned by adjusting the outer\u2010ring solvent, achieving activation from ambient conditions to ultra\u2010low temperatures. Finally, based on the discolored area of the 3D\u2010printed labels under temperature\u2010excursion conditions, intuitive visual warning levels were established, providing a reliable and tamper\u2010proof indication of temperature abuse.\n                    <\/jats:p>\n
