Ink is defined as a colored liquid used for writing and reading. Ink is the basis for daily functionality, and communication. Ink makes up homework, literature, business transactions. The issue however is, that ink oftentimes goes unnoticed. Often, people don’t realize that many important things to them consist of ink. This is because ink is not large, and it does not stand out, it just appears. Ink is simply something that is there and costly to replace.The history of ink dates back considerably, evolving over the ages into what it today
Ink manufactured for writing originated in Egypt and China originally dating back to around 2500 BC. This ink was composed of soot bound together with gums. This paste was formed into rods and dried before being mixed with water immediately before use. Ink of this time was only used for handwriting. Printing would then be created by the Chinese in 3000 BC. The invention of the writing brush made from hair is attributed to General Meng Tien of China. This allowed writing to be done on silk rather than with bamboo pens on strips of bamboo. Bamboo is heavy, bulky and awkward, but for all its virtues, silk is expensive. They used a mixture of coloured earth, soot and plant matter for pigments, again mixed with gums for a binder. Actual printing consisted of ink being drawn onto moveable slabs outlined with letters and signs. Then in 1440, when Johannes Gutenberg invented the first printing press with moveable type, was beginning to be made of soot bound with either linseed oil or varnish, materials extremely similar to those that are used in ink today. Following this in 1772 colored ink was introduced, however, the drying agents for colored ink would not be introduced until the nineteenth century....

Once the varnish is created, pigment dispersal occurs.This is when the pigment particles clump together. These clumps must be broken up and the pigment dispersed evenly through the resin. There are three main types of equipment used to do this. Shortly after dispersal, ink is then created.
The last step is the printing process. Printing is usually done using four different colours of ink: cyan, magenta, yellow and black. Theses subtractive colours are chosen because by 'overprinting' these inks, all other colors imaginable can be formed. For example, red is produced by overprinting yellow and magenta, as the yellow absorbs the blue light and magenta absorbs the green light, leaving behind pure red light. Black ink is used because although in theory cyan, magenta and yellow should add together to give black, they actually produce brown.
This invention was a change to the Chinese because paper was invented in China around 105 CE. So the Chinese have paper and now it allowed an easy way for people to communicate. It caused a change in their culture because with paper they can now pass down culture easier than before. Before its invention the writing surfaces that were used were, bones, tortoise shells, and bamboo slips. But as the Chinese civilization started to grow they proved to themselves that these writing surfaces won’t work because of the bulk and weight.
“Fiction is the truth inside the lie” (Stephen King). Figment of imagination helps improve brain connectivity and responsibilities which enables the brain to escape to a world of illusion. In a world of imagination students explore conflicts within the book. Anecdotes play a significant role in building the strategies used to deal with real world events. Ink and Ashes by Valynne E. Maetani, discusses how mistakes from the past has an impact on your life and may alter your future. Books intended to be read so that we as people can have a different mindset and perspective on things rather than just our own.
Tattoo ink is made up of pigments and carrier molecules. Ink is formed of water, alcohol, and glycerin. The pigments that are in the tattoo ink are mineral pigment, organic pigment, vegetable-based pigment, and plastic-based pigment. The pigments contain organic and metallic elemental composition. The plastic-based pigments are very intense colors. There are also pigments that glow in the dark. The reason they have
The first printing press was created to make books (Mostly bibles in the day) cheaper and more accessible. At this time only nobles and scribes new how to read and write. In result of this press, written pieces became commonplace making the common people needing to know how to read and write. This literacy spread and spread as the printing press became more common and caused the majority of the world’s people to be as literate as it is today which helped to revolutionize the work
The cutouts were then placed into large test tubes containing 4ml of isopropyl alcohol for each pigment band, total pigment sample 1, and total pigment sample 2. They were then sealed, until the pigments from the paper transferred onto the isopropyl alcohol. The same amounts of smaller test tubes were obtained, plus an additional small test tube, which was filled with isopropyl alcohol and acted as a blank. The eluted pigment solution lacking the paper was transferred into the rest of their respective smaller test tubes.
Organic inks, which are my personal professional preference, are the safest on the market. These types of inks are typically derived from plant matter. Vegan inks are also in the same class as the organic inks as well and are also ranked just as safe as organic inks.Organic inks are also safe to digest. I personally have no plans on digesting tattoo ink, but if I planned on doing so at least I know that it is safe.
The dye transfer process major manufacturers in the 60’s were Kodak and Polaroid. It was the most successful and popular of color photography. The material used for the dye-transfer process was manufactured starting in 1945. After 1993, when it stopped being manufactured, people had to stockpile the materials to keep producing their own dye-transfer prints. Today, after about seventy years, the dye-transfer prints are valued and very highly considered to be stable, but only a handful of people still make prints who use the dye-transfer process remain. After 1991, Kodak discontinued the Pan Matrix Film, which was used for printing from separations, and in 1994, Kodak ceased production completely along with the rest of the dye transfer materials.
The printing press was invented in 1453. The movable printing technology was invented in China in 1040 but Johannes Gutenberg was able to perfect this technology by creating the Gutenberg printer in 1440. The printer was a movable type. A movable type was where individual blocks could be set up in order to print almost anything. Before this, wooden blocks, carved by hand were used to print things. These blocks would have consisted of what the individual wanted to print which would take an incredible amount of time. Gutenberg’s invention of a movable type printer established the ability for mass communication.
A controversial topic today is whether or not body piercings and tattoos should be accepted by professionals working in health care. Currently, tattoos and piercings are allowed in health care as long as they are not visible. According to one of the studies, “Body piercing is defined as a piercing of the body anywhere other than the earlobes” (Westerfield). Therefore, the only visible piercings allowed are small studs in the lobes of the ears for females. The reason body piercings and tattoos are not suggested in health care is that they keep someone from looking professional as well as making them look intimidating. Not everyone sees them that way. The opposing side is that they do not affect
"It's best if the ink originates from a substantial maker that has been doing business quite a while, and far and away superior if the craftsmen have attempted the ink on themselves," .The polluted ink in the late flare-up originated from a little retailer, he called attention to.
The three dyes formed, one in each emulsion layer, are the subtractive primaries yellow, magenta and cyan. All silver is then bleached out and each layer is left with a positive color image.
We took pictures of each other’s data once finished with the lab. For the paper chromatography, students began by grinding 5g of spinach along with 2g of anhydrous magnesium sulfate. Students added hexanes and acetone as specified by the lab protocols. Once, the solvent was a dark green color, we placed it in a centrifuge and transfer the liquid portion of the solution into a test tube. Throughout this portion of the experiment, students used weighting paper as a funnel poring the indicated solution as stated by the protocol, for instance pouring silica gel and sand into the column. After, we poured about 3ml of Hexanes into the column, making sure not to let the column dry. We then added, spinach extract to the column—after, we added about 1ml of hexanes. Adding hexanes caused the solution to gain a yellow colored band. We added hexanes until the yellow band reached the bottom of the column, thus began to collect all the yellow pigment into a test tube. Once the elutant become colorless, we once again placed a waste basket under it. Finally, we collected the green pigment into another test tube by a 70%/ 30% mixture and a bit of acetone. Once the two colored bands were collected, we obtained the wavelengths of each colored band using the
Once a student has developed a little self-confidence in creating a pleasing drawing, he is most anxious to embellish it in some way. That is usually color. To keep things simple and inexpensive, the artist may choose to do pen and ink drawings and illuminate them with watercolor. Artists also use this technique to expand on ideas they have for future, more heroic works. However, a good pen and ink drawing can stand on it is own as a final output with no apologies needed.
The basic process of making paper has not changed in more than 2000 years. It involves two stages: the breaking up of raw materials in water to make a suspension of individual fibbers and the formation of felted sheets by spreading this suspension on a porous surface, to drain excess water. The essential steps of papermaking by machine are identical with those of hand papermaking just much more complex. The first step in machine papermaking is the preparation of the raw material. For centuries, the main raw materials used in papermaking were cotton and linen fibbers obtained from rags. Today more than 95 percent of paper is made from wood cellulose. Wood is used mainly for the cheapest grades of paper, such as newsprint. Cotton and linen fibbers are still used for high quality writing and artist’s papers. Many kinds of wood can be used such as aspen, beach, birch fir, gum, hemlock, oak, pine, and spruce.
Human beings are creative species. They have come up with great ideas and invented some wonderful tools since they have been on earth. From the time that someone threw a rock in the ground to make the first tool, to the introduction of the wheel, to the development of electricity and the Internet. These alterations, and many more have been made to provide us the modern life we are living today. There are many inventions that have changed the world dramatically. Historians suggest that the printing press was one of the most revolutionary inventions in the human history. The printing press was invented over five-hundred years ago and was the first step in transforming societal literacy. Around 1440, the printing press was invented by the German Johannes Gutenberg, who was the first to design a technique that has the ability to transform the ink from the movable type to paper. Basic development of the printing press was, the hand mold which is the process that enabled the production of metal movable types. Printing presses with this movable type mechanism increased the rates at which copies of books
