HP inkjet cartridges
Are you in need of HP inkjet cartridges for your printer? Inkjet inks have has certain problems associated with them, one of which is the opposing requirements for a colouring agent that not only allows for rapid dispersement of the fluid but also stays on the surface.
HP inkjet cartridges and desktop printers use aqueous inks which are a combination of water, glycol and dyes. Often the solution to the ink staying on the surface is to ensure that the media is specially coated. Thermal inkjet heads require water to work effectively and therefore aqueous inks are the most compatible. They also provide the most vivid colour with the broadest range. HP inkjet cartridges offer you the best quality for your HP inkjet printer.
Aqueous inks can either be dye-based or pigment-based. The former are usually less expensive but can fade more easily whereas the latter, while being more durable is more costly. If an ink states that it is “Archival Quality’ it usually means that it is pigment-based.
Many of the latest inkjet printers also use a much wider range of inks including the aqueous version. These printers not only require a higher level of maintenance but also piezo inkjet heads. The other kinds of inks that can be used are solvent, UV-curable and dye sublimation.
The main ingredient in solvent inks are Volatile Organic Compounds (VOCs) which have high vapor pressures. They use pigments rather than dyes and therefore are less subject to fading. The main advantage of these is their cost and the flexibility when printing on uncoated vinyl substrates such as banners, vehicle graphics and billboards. The print speed for these inks is very good but they demand special drying equipment like blowers or heaters. The other main disadvantages are environmental as the solvent produces a vapour and the solvent itself needs to be disposed of. You can now get mild or ‘Eco’ versions of solvent inks that, although still not as safe as the aqueous inks, can be used in enclosed spaces without specialised ventilation. The colour quality of these ‘Eco’ inks increases each year and therefore so does their market share.
UV-curable inks are cured by exposure to UV-light. Their main advantage is that they dry incredibly quickly and can be applied to a range of uncoated substrates. This curing requires special modules for the printer that can increase the cost. Dye sublimation inks print directly onto fabrics. When heated the dyes sublimate into the fibres and create a very durable image with strong colour.
