There are two types of printers that are well-known and inexpensive for print jobs. They are the inkjet and laser printers used frequently in homes and offices. Inkjet printers make use of liquid ink, while laser printers utilize toner in a powdered format to print an image on the substrate. In this article we’ll go over the way the printer’s ink performs its function.
Let’s get started with the basics.
What is Printer Ink made of?
Printer ink is composed of many components such as pigment varnish, resin solvents, waxes, fluids, and more. Inks that are black are typically made using charcoal-black pigments. Titanium dioxide, on its own, however, is commonly used as a white pigment.
Printing companies as well as third-party producers of cartridges that are compatible with printers are not able to divulge the composition of their inks for printers. This is a trade secret in the end.
The two most well-known inks used by printers are:
- Dye-Based
This kind of ink contains a colorant that is totally dissolving into a liquid like a glycol or water. The ink is able to flow effortlessly through the print head and onto the substrate and dry in just a few minutes. Dye-based inks tend to be more affordable. Inkjets that use dye-based inks produce razor-sharp text and good-looking images with vibrant colors. However, dye-based inks are much more likely to stain, and prints tend to fade after five years.
- Ink Based Upon Pigments
It’s made of pigments in solid form, which is suspended in a liquid. The ink that’s made up of pigments is more durable due to the fact that it’s resistant to fade for a longer period of time. The colors that are produced through pigmented inks might not be as vivid, however, they’re a great option to print on surfaces that are slippery like transparent or stickers.
The difference in quality between the inks’ output that is based on dye and pigment is difficult to determine for those who aren’t used to it.
Whatever type of ink is utilized by an inkjet printer, there are methods to make sure that the ink used by printers lasts for longer.
Where is the Location in which Ink for Printers is Stored?
The ink of the printer is stored in cartridges. It’s identified by a specific cartridge number. Different printer models make use of different cartridges.
Ink cartridges are classified as standard yield or high yield’ according to the quantity of ink they will hold.
The high-yielding Epson or Canon Printer ink cartridges, for example, print faster since they can retain more ink. Printing enthusiasts often purchase ink cartridges with high yields to reduce printing costs.
A typical inkjet printer made for professional use has three colors, including black ink. Three primary colors are cyan, magenta, and yellow. The primary colors produce the other colors printed using mixing. Photographers, graphic designers, and others who require high-quality prints, select inkjets that have at minimum four, five, and six different colors.
Inkjet printers are typically equipped with black cartridges of ink. Inkjet printers may use a single cartridge that houses all colors or separate cartridges for ink that can be used for every shade.
Inkjet cartridges also have microchips and other electronic components that assist in controlling the flow of ink as well as determining the amount of ink left.
The Print Head
Inkjet cartridges may be equipped with a print head that is integrated.
- Fixed Print Heads
Some printers are equipped with built-in print heads that differ in color from cartridges that are part of the printer. Epson together with Canon are two firms recognized to provide the greatest amount of printers that come with print heads that are fixed. The latest models produced by HP such as those of OfficeJet Pro 8620 have fixed print heads.
- The Disposable Printhead
In this scenario, the print head is included in the cartridge of the printer which is reusable. Hewlett-Packard generally supports making use of disposable (separate) printing heads. Canon also adopted these same principles of design when first introducing printers.
There’s a third option and companies such as Kodak offer printers with refillable cartridges for ink and separate printer heads that can be disposed of. HP’s high-volume inkjets as many of the newest models produced by Canon are currently using this type of design. Print heads are built to last the life of the machine, but the user can exchange them if they require to.
How does the Print Head Work? What does it do?
The print head comprises many microscopic nozzles that are closely arranged to spray ink on the substrate like cardboard or plastic film canvas fabric in small, precise drops.
Most modern printers that are used in offices as well as home use technology referred to by the name Drop-on-Demand (DOD) technology.
DOD technology can further be divided into two distinct types.
- Models produced by Canon, HP, as well as Lexmark, utilize technologies like thermal printing. The cartridge used for printing is made up of small chambers, each with an electric heating element of tiny size. In the event that electricity flows to the element which heats the chamber, the ink is evaporated and forms the shape of bubbles. The droplet of ink is transported through the nozzles on the printer heads placed on the substrate because of increased pressure inside the chamber. Since the ink has to evaporate, the process demands that the ink contains some volatile components.
- Printing devices made by Brother and Epson use the technology of piezoelectrics. A large number of industrial inkjets are based on this printing technique. Instead of heating the component, piezoelectric materials like lead zirconium titanate are put behind a nozzle on that head. When the energy source is applied to the piezoelectric material, it changes its shape and then pushes the droplet of ink into the chamber that has ink on the paper. The print head for an inkjet that is piezoelectric costs more but it is also less prone to blockage.
In both instances, it’s the computer program that directs the printer to release a specified amount of ink droplets for each dot.
