Classification: CPC B  C | IPC B

Claim 0:
1. A printing method comprising:
discharging ink to a substrate;
heating a non-ink-discharged side of the substrate at a temperature of T1; and
heating an ink-discharged side of the substrate at a temperature of T2,
wherein the following relationship (1) is satisfied:

0 degrees C.≤T2−T1≤90 degrees C.  Relationship (1),

wherein the ink comprises:
an organic solvent A having a boiling point of lower than 250 degrees C.;
an organic solvent B having a boiling point of 250 degrees C. or higher; and
a resin,

wherein a proportion of the organic solvent A to the ink is 30 percent by mass or less,
wherein a proportion of the organic solvent B to the ink is from 1 to 3 percent by mass,
wherein a proportion of the resin to the ink is from 5 to 15 percent by mass,
wherein the ink has a viscosity of from 8.0 to 11.0 mPa·s at 25 degrees C. and from 5.5 to 11.0 mPa·s at 36 degrees C.,
wherein a droplet of the ink having a volume of 2.5 μL discharged to the substrate shrinks to 0.1 μL or less in 10.0 seconds or less at 25 degrees C.
