Have you ever stopped to consider what printer ink is made from? Or why it is so expensive? Below is an overview of printer ink, what it is made from, and the manner in which it is manufactured.
What Materials are used to Make Printer Ink?
The ink comes in the form of paste or liquid which has dyes or pigments. The pigments are responsible for giving the ink its coloration. They are derived from multiple sources which are rich in nitrogen compounds. Within printers, ink is utilized to create digital images or text copies.
The majority of the ink which is produced today is designed for printing work, where the color is provided by the pigments instead of the dyes which are used for writing ink.
How Printer Ink is manufactured
The ink consists of multiple ingredients such as resin, solvents, pigments, varnish, and additives like lubricants and wax. Black ink uses carbonized black pigments, while white pigments such as titanium dioxide are used for lighter ink colors.
Varnish is the clear liquid that serves as the ink base. Different varnishes will be applied towards different inks, but all are designed through the mixing of additives, solvents, and resins at elevated temperatures which results in a mixture that is homogenous.
Resin is designed to bind each ink component together. They will react with one another while giving the varnish greater viscosity. The pigments will then be mixed with the varnish until they are ground down and the clumps are removed so the colors will spread evenly within the ink.
The Making of Ink Colors
Inkjet-style printers will spray miniature ink droplets through small nozzles onto the paper to produce a digital copy of images or documents. Toner is different and consists of a powder that is very fine and comprised of polyester, which is a form of plastic.
Toner is used primarily in laser printers where the laser will produce a template that is electrostatic for the image in a metallic drum that rotates and that can carry the electrical charge. The cartridge will dispense the toner on the drum, and will only stick in specific areas where its laser alters the electric drum charge.
Distinct color pigments will be applied to produce specific ink colors. While most white and black inks are derived from titanium dioxide or carbon black, they might be combined with various pigments to change their color.
Classical printers utilize four primary ink colors, which are magenta, black, yellow, and cyan. When these colors are combined in various proportions, the end result is a broad color spectrum that can be used to print fully colored documents. Newer printers such as LED and laser models will use extra inks like grey, light magenta, or light cyan to enhance accuracy and image quality further.
Why Does Printer Ink Cost so Much?
Anyone who has ever owned a printer knows how expensive the ink can be. Many users try to get around this by purchasing low-cost cartridges in an attempt to save money. However, the wiser course of action is to purchase the official toner or ink cartridges for your model, because they will last longer.
What is the Difference between Toner and Ink?
While both toner and ink are utilized for business and home printing, they are different in the manner that they’re placed on paper. Ink is liquid that has been tinted using dyes and pigments and is utilized by older inkjet printers. It comes in two forms, which are colorants which are dye-based and dissolved inside the liquid, and fine powder which is pigment-based and liquid suspended.
Ink cartridges are usually found in inkjet printers and are the container that holds the ink which is placed on the paper while printing. Every cartridge contains at least a single ink reservoir and some have multiple; manufacturers might also install chips or electronic contacts with which the printer communicates.
Dispersants and Resins
Dispersants are substances designed to aid ink flow. They slow pigment particles down which allow ink to surface transfer with greater ease during printing.
They are comprised of solvents which consist of surfactants and polymers. They will draw the particles in to produce a coating. The size of the pigments will vary, which influences the color level which is used.
Resins are responsible for helping all the ink components stick together along with the print surface. It can be found in most cartridges and includes acrylics or formaldehyde which aids in the creation of surfaces that are glossy and resilient against damage and high temperatures. They play a key role in the creation of printer ink.
Humectants and Defoamers
Humectants extend the ink aging process and allow it to last longer, while the primary purpose of defoamers is to minimize bubbles. Wetting agents aid with different surface types and precautions must be taken to stop fungi or bacteria from growing within the cartridge.
Color Pigments and Carbon Black
Contemporary printer ink is comprised primarily of a special pigment called carbon black. It will be mixed with a solvent, additives, and binders like drying agents. The resulting mixture might vary based on the cartridge brand, along with the process used for printing.
Pigments play a key role in print ink since they are responsible for providing its color, and will protect it against extreme heat and multiple solvents. Sometimes the pigments will be mixed with opacifiers, which causes the ink to become opaque, or extenders that provide balance for the appearance of the pigment. The pigment might also be pulverized so it will displace in a more even manner within the fluids.
The Varnish Base
In the last stage, pigments will be mixed with the varnish base. This base might be derived from distillate or oil to produce ink that will dry. Black ink will be made from varnish and carbon black, while the colored ink is comprised of numerous dyes and compounds which assist in the creation of color pigments.
Dyes come in many forms, including inorganic and organic materials, which are responsible for the creation of colors that are viewable today in print images and documents. White pigments can be utilized for modifying them as needed.
The printer ink made today is non-toxic when used in miniature quantities. Additionally, most print manufacturers are heavily regulated with strict safety guidelines and rules that they must follow. That being said, printer ink should never be ingested and ink cartridges should be kept away from small children. The packaging should contain detailed information regarding the chemicals used within.
