The INK is most important part of Digital Printing machine?

The core of any inkjet printing system is the ink, which is essentially pigment base in a carrier liquid. The job of the ink is to deliver the pigment to the media called vehicle and to bind it to the media’s surface called resign. The range of substrates that the ink will work with, ultimately determines the applications.

How its work?

The solvent used in solvent ink serves a dual purpose in that it’s both a carrier to deliver the colored pigment to the media, and it helps to melt the surface of the media. The ink colorants can penetrate beneath the softened surface to bite into the media itself.

Additive formula;

When the solvent evaporates, the colorants are left etched into the media which produces a very robust image able to withstand scratching and weathering. This also allows solvent inks to work with a tremendous range of media, including very cheap uncoated media. The solvent content in this type of ink can account for up to 90 percent of its volume.

Inks for uncoated media;

Today most manufacturers offer a choice of eco-solvent or light solvent inks, with the latter using a more aggressive type of solvent. This should work with a wider range of uncoated media as well as having better colour gamut.

Solvent should be evaporate completely before lamination;

It’s widely used in vehicle graphics, where the inks have to be heated up and stretched to fit around difficult shapes such as door handles. However, the major disadvantage of solvent ink is that although the prints are touch dry as they come off the printer, they still need to be left for up to 24 hours to allow the solvent to evaporates completely from the media. This delays any finishing, such as lamination.

Hybrid inks Available

Several manufacturers are working on hybrid inks, which attempt to combine the best features of different inks. The most obvious example is Solvent UV which combines mild solvent with UV-curable ink.
