HIGH VISCOSITY JETTING METHOD

A high viscosity jetting method wherein a liquid is jetted by a printhead through the nozzle (500) in a nozzle plate (150); and wherein a section of a nozzle (N s ) has a shape (S) comprising an outer edge (O E ) with a minimum covering circle (C); wherein the maximum distance (D) from the outer edg...

Beschreibung
Zusammenfassung:	A high viscosity jetting method wherein a liquid is jetted by a printhead through the nozzle (500) in a nozzle plate (150); and wherein a section of a nozzle (N s ) has a shape (S) comprising an outer edge (O E ) with a minimum covering circle (C); wherein the maximum distance (D) from the outer edge (O E ) to the centre (c) of the minimum covering circle (C) is greater than the minimum distance (d) from the outer edge (O E ) to the centre (c) from the minimum covering circle (C) times 1.2; and wherein the jetting viscosity of the liquid is at least 20 mPa.s. A printhead suitable for jetting a high viscosity liquid is also disclosed.
