Publication number: 20140292843Abstract: The present disclosure is related to deposition of print treatments. In an example, treatment is to be deposited on substrate dot locations to receive ink according to selected treatment-to-ink regimes. The selected treatment-to-ink regimes include a variable treatment-to-ink regime and a constant treatment-to-ink regime. The variable treatment-to-ink regime is for depositing a variable amount of treatment dependent on the amount of ink to be deposited in a substrate dot location when the ink amount in the substrate dot location is below a threshold. The constant treatment-to-ink regime is for depositing a selected constant amount of treatment in a substrate dot location and an area surrounding the substrate dot location when the ink amount in the substrate dot location is above the threshold. Other examples are illustrated herein.Type: ApplicationFiled: March 28, 2013Publication date: October 2, 2014Applicant: Hewlett-Packard Development Company, L.P.Inventors: Jaime Fernandez del Rio, Eduardo Amela Conesa, Jacint Humet Pous, Marc Serra Vall
