Embodiment Construction

[0021] The exemplary embodiments are intended to cover all alternatives, modifications and equivalents that may be included within the spirit and scope of the devices and systems described herein.

[0022] The modifier "about" used in conjunction with a quantity is inclusive of the stated value and has the meaning dictated by the context (eg, it includes at least the degree of error associated with measurement of the particular quantity). When used for a specific value, it should also be considered disclosing that value.

[0023] Reference is made to the drawings for a suitable understanding of the inks, methods and systems of the embodiments. In the drawings, like reference numerals are used throughout to designate like or identical elements.

[0024] Aqueous inks according to embodiments are suitable for ink-based digital printing using anilox rolls and inkjet ink delivery subsystems, and are also advantageously suitable for inkjet printing in general. Aqueous inks accordi...

Abstract

The present invention discloses ink compositions or ink concentrates for variable data lithography or inkjet printing, comprising a nanoparticle polymer or a blend of nanoparticle polymers, wherein the polymer or the polymer of the blend is The substance is water dispersible at temperatures below 100°C; and the solids content is an amount greater than 25% by total weight.

Description

technical field [0001] The present disclosure relates to inks for printing images on substrates such as paper, plastic, metal or other printable materials. In particular, the present disclosure relates to aqueous dispersible polymer inks that are particularly suitable for imaging or jetting onto intermediate substrates. Background technique [0002] Conventional aqueous thermal inkjet or piezoelectric aqueous inks have been found to cause wrinkling, bending and / or show-through, which can be easily seen when printing on plain paper, especially if the amount of water in the ink exceeds 50% by weight. Also, printing on non-porous substrates requires specialized ink formulations with incorporated binders and drying systems, which often limits printing speed and increases the cost per print. [0003] A number of approaches have been used to extend the printing range of aqueous inks, including the use of hydrophobic and / or coagulating primers on substrates. The use of basecoats ...
