Abstract: A viscosity measuring method includes: immersing a plunger into a sample contained in a cylindrical container by an initial depth L0; further immersing the plunger at a velocity vp1 by a distance ?L1, and measuring a force applied to the plunger; obtaining first peak value FT1 and a first convergent value FTe1 of the force; returning the plunger to the initial depth L0; further immersing the plunger at a velocity vp2 by a distance ?L2, and measuring a force applied to the plunger; obtaining a second peak value FT2 and a second convergent value FTe2 of the force; obtaining a flow behavior index n; and calculating an apparent viscosity ?a of the sample based on Expression (1).

Abstract: A solid pharmaceutical preparation printing method in which printing is performed on successively-supplied solid pharmaceutical preparations by discharging ink from a nozzle of a printing device based on printing data, the printing data including standard printing data and rotated printing data created by rotating the standard printing data at a selected rotation angle, and the printing based on the rotated printing data being performed in addition to the printing based on the standard printing data.
