Inkjet Head "CE4"

Inkjet Head "CE4"
A wide range of drop volume control with 1 to 15 drop mode.

A wide range of drop volume control with 1 to 15 drop mode

  1. Higher nozzle density with 636 channels
  2. Wide range of drop volume
  3. Higher driving frequency(especially at small drops)
  4. Excellent dot placement accuracy
  5. UV curable and Oil based pigment ink compatible
  6. Stable jetting with water circulation thermal control

Features

1. Higher nozzle density with 636 channels

CE4 is designed and more suitable for single pass application with its 300dpi resolution.
Compared with conventional binary inkjet heads, it is more suitable to express smooth density gradation from light to dark for various industrial printing.

Example of single pass applications

2. Wider range of grayscale up to 16 levels

Unique technology of jetting multiple drops onto a single dot creates wide range of grayscale with minimum 6 pl to maximum 90 pl (15 drops) per dot. (equal CA4)
Compared with conventional binary inkjet heads, it is more suitable to express smooth density gradation from light to dark for various industrial printing.

3. Higher driving frequency(especially at small drops)

CA4 realizes 28KHz at 1drop (6pL) mode, which is twice as fast as the existing CA3 using the same interface.
Even in 7-drop mode (standard 8 gradations), it achieves a speed of 6.2KHz (approximately 1.3 tiems faster compared to our previous model). The linear speed is 35m/min in (6pl, 1200dpi) mode and 31m/min in (42pl, 300dpi) mode, making it suitable for highly productive industrial applications.

Higher driving frequency(especially at small drops)

  • Data transfer mode is different in 15KHz or more.
  • Driving frequency in CA3's 1-6drop is a reference value.
  • Above data is based upon RISO TECHNOLOGIES' internal test result. Optimized driving frequency may vary depending on the ink to be used.

4. Excellent dot placement accuracy

Accurate dot placement

Excellent dot placement accuracy is achievable with excellent piezo process and jetting control technology.

(1) For a single pass type application

  • realize higher print speed.
  • realize wider swath by assembling multiple heads into a wider array.

(2) For a scanning type application

  • improved throughput by reducing the number of scanning.
  • further improvement in printing speed by adding more printheads per color.
