The jet stability and break-off behavior with respect to the fluid properties are stated in well-known theories such as Navier-Stokes equations and the Rayleigh theory. During recent years many computer simulations have aimed at predicting the jetting process in specific print heads and, more importantly, for establishing a methodology for selection of ink additives. ... 

A generic inkjet ink formula is shown in Table 1 below. Though the principal ingredient is water, the "other stuff" — the co-solvents, surfactants, colorants, and other additives — lend the ink many useful properties. Hundreds of distinct ink formulations have been sold by numerous manufacturers, each tuned for a slightly different set of applications. Even if such formulations were readily disclosed to the public, it would be impractical to attempt to relate each ink additive to a particular property or performance attribute, simply... 

We end this chapter with an example that illustrates some of the aforementioned concepts. The inks described here are completely fictitious — physical properties are estimated and not measured — however, attempts are made to include ink additives from actual patent examples. 

In conclusion, there are many performance attributes to consider when formulating water-based inkjet inks, and multitudes of ink additives that can be employed. To achieve effective formulations, it is useful to first consider the relationship between ink physical properties and desired performance targets. Taking such an enlightened approach helps narrow the list of ink additives to be tried, expedites ink development, and ultimately increases a product s chances for commercial success.

The most important rosin derivatives used in printing ink formulations are rosin oligomers and their esters, metal resinates, modified phenolic and alkyd resins, ester gums, maleic and fumaric acid adducts and their esters. Practically all types of printing inks can be manufactured with rosin-based components, because they provide good miscibility and compatibility with most film formers and other ink additives. 

Poly(acrylates) and poly(methacrylates) are commercially important polymers with a myriad of uses, including paper and textile coatings, adhesives, caulks and sealants, plasticizers, paint and ink additives, and optical components for computer displays. Since they are derived from monosubsti-tuted and unsymmetrical 1,1-disubstituted vinyl monomers, poly(acrylate) and poly(methacrylate) products with a spectrum of tacticities and thereby mechanical properties are potentially accessible. To date, however, industrially produced materials are generated using free-radical polymerization technology, which offers limited scope for tacticity control. Therefore, there has been much interest in the development of metal-catalyzed routes to these polymers where the coordination environment of the metal offers the potential to influence tacticity.
