Abstract

Ink viscosity information of an inkjet printing apparatus can be provided at low cost in small space. The inkjet printing apparatus performs image printing by using a printhead with a plurality of nozzles from which ink is discharged. This inkjet printing apparatus includes a switching unit which switches to a test print mode for providing the ink viscosity information. The inkjet printing apparatus also includes an image printing unit which prints a predetermined image in response to a plurality of driving pulses with different frequencies to obtain a test print pattern, when the switching unit switches to the test print pattern.
