Abstract
Provided is a lithographic ink having superior surface staining resistance and fluidity. Also provided is a method for manufacturing a printed material using the lithographic ink. The lithographic ink has all of a viscosity (A) at a rotational speed of 0.5 rpm, a viscosity (B) at a rotational speed of 20 rpm, and a viscosity (C) at a rotational speed of 50 rpm of 5 Pa·s or more and 100 Pa·s or less, the viscosities (A), (B), and (C) being measured by using a cone-plate rotating viscometer at 25° C., and has a viscosity ratio (C)/(B) of 0.8 or more and 1.0 or less.
