To know how well inks can be applied on particular media, we first need to be familiar with ink compositions. links generally consist of a colorant,a carrier medium and a water-soluble resin.in terms of the colorant,there are dye-,and pigment-based inks.because their raw materials come from natural plants,dye praticles are highly delicate and execllent in color performance. usually,dye-based inks achieve high-quality graphics,but it is known that these types of inks provide low durability.

unlike dye-based inks,pigment-based inks are made of other kinds of materials,like stone dust.

compared with dye-based inks,their outdoor durability is better although their color performance is worse. according to digital printing industry experts,water pigment-based inks achieve 70% of the market share in the home digital printing market. that is why digital printing banner market is huge and massive.even though solvent-based inks with high outdoor durability have been popular in the market for a few years,water-based inks have still shared a great portion of market.but it is expected that there will be big change of market for digital printing inks.
