This method is used to measure the absorbency rate of paper for printing inks having an oil vehicle. It is normally used only for easily permeable papers such as news, book, and mimeograph (1,2); however, it can be helpful for any paper where the absorbency of an oil based vehicle is important.A correlation has been established between the results of this test and the printing quality of uncoated papers. The oil absorbency of paper is related to the porosity and internal structure of the paper.
