Abstract
Protrusions are positioned on the inner surfaces of a channel within a printhead body or member to control the size and location of bubble formation. An inkjet printhead includes a member having a first opening and a second opening to enable melted ink to enter the channel at the first opening and flow through the channel to the second opening. At least one protrusion extends from the member into the channel to position a portion of the protrusion into melted ink in the channel to form a dominant stress concentration in the melted ink.
