The Current Status of Toshiba Tec's Latest Inkjet Printing Technology —Ink Recirculation Inkjet Heads and Compact Ink Recirculation System—

Abstract

We will introduce our ink recirculating inkjet head“CF3”and compact recirculation system“CC1”according to their basic principles.

Based on actual examples of the basic configuration of ink recirculation, we will explain our concept on pressure control of various parts, flow rates of ink recirculation, and the negative pressure of nozzles.

In addition, we will explain the functional effects of ink recirculation, such as self-recovery of jetting failure, stable jetting performance, and support for high viscosity and/or gravity inks.

Next, we will describe the features of CF3, such as compatibility of small characters and wide print gaps, and the capability of micro-adjusting jetting volume, separate from the normal gradation control.

Lastly, we will explain the basic specifications of our compact ink recirculation system CC1, which holds all the elements required for ink recirculation.
