The hardness of squeegee material is measured with a durometer and the results are given in a specific durometer. Differing durometers will produce a difference in ink deposit, with lower durometer (softer) blades generally producing more deposit. The durometer of the squeegee should be noted on the Print Data Sheet for each job, as you will want to assure that you use the same durometer on repeat orders. The manufacturers stated durometer of a urethane squeegee can be off by as much as ±5° of the stated hardness. Measure before using!
