Abstract
A printer selectively ejects ink droplets or jets out ink mists depending upon input data of an image to be recorded. The printer has a drive signal generating section and a recording head. The drive signal generating section generates two drive signals, first one for causing the recording head to eject ink droplets to record edge portions of a solid tone level of gradation in the image and the second one for causing the recording head to jet out ink mists to record portions in the image other than the edge portions. The first signal has lower frequency than the second signal. The recording head has liquid ink chambers, each of which has an ink nozzle. A liquid level of ink in each liquid ink chamber is controlled when the first signal or the second signal is applied to the recording head.
Claims10
An image recording method for recording an image having edge portions of a solid tone level of gradation therein, having steps of;
- recording the edge portions with dots to form a solid tone;
- recording portions in the image other than the edge portions using ink mists that are generated by converging ultrasonic waves in ink.
A printer comprising:
- a recording head which ejects ink droplets or jets out ink mists selectively, depending upon input data of an image;
- and
- a selector receiving the input data and supplying the recording head with a signal to jet out one of the ink droplets and the ink mists.
A printer having at least two recording heads,
- a first being a recording head which records edge portions of a solid tone level of gradation in an image to be recorded with dots to form a solid tone, and
- a second being a recording head which records portions in the image other than the edge portions using ink mists that are generated by converging ultrasonic waves in ink.
