Dimensional Scaling of Aqueous Ink Imbibition and Inkjet Printability on Porous Pigment Coated Paper–A Revisit

Abstract

A recently published dimensional scaling of infiltration of water-based inkjet fluids was used to revisit published inkjet printability data on mineral-pigment-based, inkjet-receptive coated papers. The dimensional scaling was developed using simple fluids on homogeneous isotropic media and applied on uncoated papers using complex inkjet fluids but so far has not been related to printability. It is shown that the scaling can also work for coated papers using commercial dye- and pigment-based inks with a suggested relation to printability as given by the color gamut area, in which the primary factor is the product of permeability and capillary pressure. A successful scaling suggests that inkjet printability can be predicted from flow and materials parameters, namely, porosity, viscosity, imbibed volume, permeability, and capillary pressure, and would be of general applicability in other areas of inkjet printing. The results further imply the usefulness of the approach in other functional surface modification using waterborne procedures on hard or soft porous materials.

Simulation & modelling of dilute solutions in drop-on-demand inkjet printing: a review

“…The ink vaporizes through the heat and consequently creating a bubble which with high pressure (more than one Mega Pascal) causes a wave force inside the fluid of reservoir to exit a droplet via the nozzle. The advantage of this system is the comparatively low cost, as it includes only a resistor and a reservoir, easily fabricated via existing methods with low-cost goods [32,33]. So, thermal inkjet printers are generally used as household systems, where cost and simple print head replacement are important.…”
