A method and an apparatus for measuring the tack of pastelike substances, in particular printing inks, includes a drive roller ( 2 ) and a contact-pressure roller ( 3 ), between which the substance ( 5 ) to be measured can be introduced and uniformly distributed. To enable replicable measurement of the tack of pastelike substances ( 5 ), the invention proposes measuring the force exerted by the substance ( 5 ) on at least one predetermined surface region ( 6 ) of the drive roller ( 2 ) or of the contact-pressure roller ( 3 ), for instance by means of a highly dynamic miniature force sensor ( 7 ), directly in this surface region ( 6 ) as a function of the respective rotary angle (alpha) of the corresponding roller ( 2, 3 ), and then using this force course for determining the tack of the substance ( 5 ).
