PROBLEM TO BE SOLVED: To judge the quality of ink characteristics such as ink storage stability and issue stability by filtering ink using a membrane filter of specific pore size to determine filtration pressure and filtration rate and then based on a specific relationship between the above two parameters. SOLUTION: The quality of ink characteristics is judged by filtering a specified amount of ink using a membrane filter with a filtration pore size of 3.0 μm to determine filtration pressure (x) mmHg and filtration rate V g/s and based on the relationship: V>8×10-5Ln(x)-0.0002. |
