Inks are chemical solutions used to colour textiles, paper, plastic or other surfaces; the different substances that produce inks are called pigments. Examples of inorganic pigments include carbon black and iron oxide, while organic pigments consist of dyes and lakes. The process by which manufacturers make pigments can vary depending on their source materials and the quality they require them to be. As such, there are several ways to produce pigment inks.
What Are Inks Made Of?
Inks are made of a variety of different materials and chemicals, but most inks contain pigment, water, and preservative. When you get an ink spill on your clothes or hands, some of the dye from the pigment will leave a mark. Plastic pigments inks are made from solid particles that can be dispersed into liquid. The most common type of pigment is carbon black, which is made by burning hydrocarbons like coal and tar until they’re reduced to soot. Other types include titanium dioxide for white ink, red iron oxide for red ink, and copper oxide for blue-green ink. Pigmentation also comes from dyes that are dissolved in the water phase before being mixed with the other ingredients. For example, black ink has traditionally been made from an Indian ink tree (Butea monosperma), a plant native to India and Southeast Asia. Dye would be extracted from the bark of this tree, and then filtered out with cheesecloth before adding it to the mixture. To make red pigment (pink), iodine is often used as it oxidizes when exposed to air producing a vivid red hue (think blood).
The most modern way to produce these substances is through chemical synthesis where all the steps are done in one place under controlled conditions rather than harvesting natural substances that can have variability based on environmental factors.
How Are Inks Made?
Inks are a liquid or paste that contains dyes and pigment. The most common inks contain either oil-based paint or water-soluble dye. The pigment is the colourant of ink, while the dye is the material that causes the color change. Dyes are used in conjunction with a carrier, usually an oily substance such as linseed oil. Pigments can be natural or synthetic and usually come from oxides of metals like iron (rust), cobalt (cobalt blue), chromium (chrome yellow), manganese (manganese violet) and copper (copper red).
The ink was first documented as being used as a painting medium in China during the Eastern Han dynasty around 200 AD.
What Are Some Other Ways To Produce Pigment Inks?
There are several different ways that you can use to produce pigment inks. One way is to use a cold process method, which involves combining pigment and resin with water in a container, and then letting the mixture stand for about 24 hours before filtering off the pigment. Another way that’s popular today is the hot process, which involves melting or dissolving pigment in a solvent, adding binders such as gum arabic or polyvinyl acetate and allowing it all to cool. This method is often used for painting because the paint will dry more quickly than from a cold process mixture. If you want even greater control over the drying time of your paints, try using an immersion blender to combine your pigments with binders. The pigment particles are more evenly distributed this way, meaning that your finished products should be less likely to crack during drying.
To develop a well-rounded understanding of the different types of inks and why they are used, it is important to first understand the types of pigment inks. There are three primary categories for pigment inks: organic, mineral and water-soluble. Organic pigments are derived from natural materials like plants, insects or minerals. Mineral pigments are naturally occurring substances that do not break down easily with exposure to light or heat. The third type is water-soluble, which is made from synthetic dyes that dissolve when it comes into contact with water. A few examples of popular organic pigment inks include umber, sienna, ochre and burnt sienna. These four colours are often found in skin tones as well as backgrounds, shadows and textures. They are typically blended with white ink so they can be lighter or darker depending on the project requirements. One example of mineral pigments is ultramarine blue, which has many uses including creating ocean waves and sky colour gradations. Ultramarine blue may also be mixed with black to create night scenes. Lastly, water-soluble dye inks are comprised of synthesized molecules created by chemical reactions between various substances such as ammonia gas and coal tar.
