Heat transfer printing ink is a key element in the field of heat transfer printing technology. In order to make the heat transfer printing technology compatible on different fabrics, it is necessary to study the rheological properties and printing adaptability of the ink coated on the paper base surface. It is necessary to transfer the oil which can be transferred to chemical fiber and natural fiber fabrics by digital printing or screen printing and other technical methods The ink is transferred to the transfer paper and then to the corresponding fabric. Through experiments, the rheological properties of heat transfer ink were analyzed, the ink density and transfer paper were measured, and the relationship between ink and printing compatibility was found out.
