Soy ink is used by the New York Times. Any ink it uses today will be obsolete when something better becomes available. At one time, though, it was the only game in town for black ink on paper.
The New York Times began as a newspaper published by Adolph Ochs that was based in New York City. It has since become one of the most trusted sources for news in the world. Today, it is known for its liberal politics and its extensive coverage of national affairs.
Ochs bought his first printing press for $10,000 and started publishing four days after the end of the Civil War in 1866. He had no college education, but he did have a good business sense and became one of the richest men in America. His son Charles took over the company, and in 1971 it was sold to Thomson Newspapers for $40 million. In 1998, Rupert Murdoch bought a majority share holding, and now runs the company through his News Corporation.
When you read The New York Times, you are reading an article written using soy-based ink. This means that any article printed between the beginning of 2010 and the end of 2012 used soy-based ink.
Color soy ink is used to print more than 90% of the nation's daily newspapers. As an alternative to soy ink, rice ink, which employs rice bran oil as a solvent, can be utilized. However, due to its higher cost, it is rarely used.
Soy ink is made from fermented soy beans and coal tar dyes. It is known for its bright colors and wide range of hues. The ink is durable when exposed to heat or sunlight and it doesn't fade when printed on paper products such as newsprint or ledger sheets.
Soybean oil is the main ingredient in most soy-based inks. Other additives include rosin (a resin extracted from pine trees), which gives the ink its drying effect, and benzene, trichloroethylene, and perchloroethylene, which are non-toxic cleaning agents that preserve the color quality of the ink.
The printing process requires several steps including setting up the press, applying the ink, transferring the image onto the paper, and finally, drying the ink so that it does not spread when applied to the paper.
Newspapers are printed in large runs on offset lithographic presses using soy ink. These presses use water to transfer the ink from the plate to the paper.
Soy ink has been proven to spread around 15% farther, lowering ink use and printer cleaning costs. Newspapers frequently utilize soy ink, particularly for color, since it produces a crisper and brighter picture. Color newspaper inks are also more cost effective than petroleum-based inks. Soybeans are converted into oil or protein products such as tofu, milk, and meat.
Newspaper printers use soybean oil for its quality and durability. The oil is mixed with water and solid particles of calcium sulfate. This mixture flows through the print head where tiny drops of oil break away from the larger mass and are deposited on the paper. As the ink dries, each drop solidifies into a hard ball that provides clear printing on a white background.
Newspaper editors prefer soy ink because it produces a less yellowed print and is easier to recycle. Soy beans are processed into oil or protein products such as tofu and milk. Thus, using soy ink results in fewer garbage disposal problems than other types of ink.
The main ingredient in most vegetable dyes is carotene. This natural pigment comes from plants and can vary depending on how the dye was produced. For example, beta-carotene is found in yellow vegetables like carrots and pumpkins, while alpha-carotene is present in red peppers and tomatoes.
In most cases, soybean oil is the primary ingredient in newspaper ink. A variety of chemicals are employed in the production of newspaper ink, with soybean oil being the most important. This is known as the "vehicle" in the ink and was originally created mostly using petroleum oil, while it is now primarily made with soybean oil. The printing process requires large amounts of oil, so much that over 50% of the volume of a newspaper is made up of oil. Soybean oil is the main component in newspaper ink because it is inexpensive and there is enough demand for it into which to export other products.
In addition to being an economical alternative to traditional fossil fuels, soybean oil is also renewable and biodegradable. It is estimated that this amount of oil would take about five years to degrade if left untreated in the environment. However, since this oil is mixed with wood pulp when printed, it will eventually decompose into carbon dioxide and water if exposed to sunlight or other forms of air pollution.
The quality of paper produced with soybean oil depends on how the oil is processed after extraction from the bean. If not done properly, the oil can contain levels of unsaturated fatty acids too high for making good ink. However, soybean oil is suitable for making printing ink because it does not go rancid like other oils do at higher temperatures. In fact, the melting point of soybean oil is around 76 degrees Fahrenheit, which makes it ideal for use in hot-press machines during printing processes.
Soybean ink is used for its black-ink printing capabilities. The paper's print mode can be set to produce black ink on white paper or white ink on black paper.
New York Times newsprint is sized between minus number 2 and plus number 4, with 4 being the most common size. Smaller sizes are called broadsheet, while larger ones are referred to as ledger.
The New York Times uses a mixture of soybean oil and linseed oil for its inks. These oils yield prints that are light weight and have good resistance to water and heat. Soybean ink was first used by the New York Times in 1851. Today, it is still used for some of its publications including Sunday Magazine and Book Review.
Linseed oil was originally used by the New York Sun newspaper from 1770 to 1800. It was then replaced by sperm oil which was eventually replaced by petroleum oil as fuel improved and the use of printed media increased. The New York Sun is now known as the New York Post.
Petroleum oil was first used by the New York Tribune in 1846.
