Abstract: A system and method upwards ink deposit onto a substrate in existing printing systems. The system provides for multiple orientations of the print head including jetting in the vertical (or generally upwards) direction to mark a substrate. The system allows the ink jetting to be easily integrated into existing converting or printing processes without the need to add auxiliary web transporting devices such as a turn bar since the print head is jetting the pigment-based ink sets vertically as illustrated in the document provided. To jet vertically the ink viscosity needs to be closely controlled utilizing in line ink heating systems that are deployed throughout the ink supply circuit. The system measures the difference between meniscus and pressure with a predetermined amount of heat applied to the system using in line/integrated heating devices in order to accomplish a vertical jet at speed.
