The novel pyrograph printing inks prepared in the above examples 1-1 to 1-5 are applied to a domestic Epson4720 nozzle digital printing machine respectively, and the test results are shown in table 1 as follows:
1. and (3) fluency evaluation: continuously printing 30 square meters of pure color blocks, judging that the broken line is less than or equal to 3 holes and the color blocks are good
2. And (3) evaluating standby performance: printing test strips in 24 hours of standby, judging that the test strips are good when the broken line is less than or equal to 3 holes
3. After a pure color block is printed on a PET film by a printer and pressed to cotton cloth at 130 ℃, the dry and wet rubbing fastness of a printed finished product is tested according to the AATCC 8 method.
