The ASTM F2498-2005 standard specifies a practice for determining the drying time of inkjet media and inks by fumigation. The standard provides a reliable test method for measuring the drying time of inkjet inks on paper or other media by fumigation method by simulating the drying process in the actual use environment. This process mainly tests the drying time of the ink surface by means of smoke covering after the ink is printed. The standard is applicable to various inkjet printing media, including paper, plastic film, etc., to help manufacturers and users accurately evaluate the drying performance of inks, and to provide technical support for the optimization and quality control of inkjet printing equipment.
