As we know, ink is one of the most critical input materials in printing processes, affecting the quality of printed products. Besides the quality of paper and other factors, uniformity and color reproduction depend on ink performance. As a result, the experiments test and verify the input ink quality based on the ISO 2846-1 international standard. Five sets of CMYK offset printing inks from five manufacturers were collected and tested. The names of the ink manufacturers will not be mentioned in this study, and the ink sets will be identified as ink set 1 to ink set 5. The results show that the ink set 1 conforms to ISO 2846-1, and the remaining ink sets have some satisfactory parameters and some unsatisfactory parameters. The results also show that the ink sets conformed with the ISO 2846-1 standard, which satisfies ISO 12647-2. This research result is very useful for evaluating and comparing the quality of various printing inks.
