A highlighter is a type of water-based ink marker used to mark text. Most markers use liquid ink and work in a similar way to markers or markers. Highlighter is a highlighter filled with transparent fluorescent ink, not black or opaque. The first precursor to the marker was invented by Japanese inventor Yukio Horie of the Tokyo Stationery Company, who in 1962 developed the first marker to use water-based ink.
Highlighter ink is made of fluorescein and dyes that give the ink its color. Moreover, highlighter tips are made of plastics such as polyethylene and polyester. The dyes used to color highlighter ink are nearly always organic compounds, and the ink may contain water and oil as well.
The first marker was invented by Dr. Frank Honn in 1962 and manufactured by the Carters Ink Company under the brand name HI-LITER. It was not created for highlighting text, but inspired Carters Ink in 1963 to manufacture similar water-based markers with translucent ink.
The following year, in 1963, Massachusetts printing giant Carters Ink developed a similar water-based marker that emitted attractive translucent ink, attractive translucent ink. In 1978, Dennison, now Avery Dennison Corporation, bought Carters Ink and began manufacturing fluorescent markers.
Some Chemistry Knowledge Regarding Dyes
Fluorescent dyes may include dyes, pigments, and the like, which impart such visible colors to the composition. In addition, fluorescent dyes can be used alone or in mixtures to produce a wide range of colors or to achieve marker ink compositional properties such as pH. Pigment inks generally use solid dyes, i.e. disperse dyes, to achieve color. In dye-based inkjet inks, a water-based liquid dye is typically used to apply a particular color to a substrate.
Depending on the required color of the ink, different dyes are used in the markers. A highlighter is a bright ink pen that is used to highlight parts of a document. These are distinct from “dry mark markers”, which are sometimes advertised as useful for highlighting books with thin pages.
Fluorescent markers are so bright because they are actually fluorescent. When used to describe markers, the word “fluorescent” is not a vague term that means “very bright.” The fluorescent marker is exceptionally bright because it converts some incoming ultraviolet light that is invisible to humans into visible light.
Why Highlighter Ink Often Appears Fluorescent
The emission isn’t very noticeable in normal daylight, but it’s quite noticeable under UV light, making the highlighter ink look fluorescent. This interaction of light and chemicals is interpreted by the eye as fluorescence. As well as absorbing visible light, the chemical structure of the dyes used in marker inks also absorb light in the ultraviolet portion of the spectrum, the ultraviolet portion of the spectrum.
When visible and UV light hits plain white paper (such as from the sun or a light bulb), fluorescent marker ink is always brighter in the visible spectrum than plain yellow marker. For example, take a normal yellow marker and a yellow marker with a yellow fluorescent substance mixed with the ink.
Making color copies of documents that contain highlighted marks is an amazing and easy way to see the effect of fluorescent chemicals on the appearance of ink. Contained means that when you make a color copy of a document that contains a marker marker, the marker in the duplicate document in the duplicate document will not contain any fluorescent chemicals.
Highlighter Dye Is Sometimes Used in Printing
The invention improves smear resistance when marking a printed image using a highlight ink composition. In one aspect of the present invention, the marker paint composition may include an acid pad having a pKa of about 2 to about 6, a marker dye, and a carrier liquid. Any suitable highlighting dye may be used in the highlighting ink compositions and can be of almost any color, fluorescent or non-fluorescent. More specifically, the present invention relates to components used in markers to reduce blurring of inkjet text or images during highlighting.
While the above lists of color pigments and dyes are provided, they are not intended to limit the present invention in any way, and it should be understood that other known pigments and/or dyes may be used in inkjet inks for use in combination. with the marker ink compositions of the present invention. When using highlighting inks in accordance with embodiments of the present invention, the acid pad can be specifically adapted to prevent dissolution or otherwise displacement of the ink jet inks from their original printed positions.
Due to the diffusion of the components in the solvent and the physical movement of the marker, inkjet dyes can be displaced from the position in which they were originally printed.
Both are usually made as ink carriers containing dyes and/or pigments. Each is in water-based ink and is rated for up to four hours without a cap. The six markers have large ink tanks in a large body, making them durable and comfortable to use.
Markers Use Nearly Identical Dye
Many markers come in bright, often fluorescent and bright colors. Since markers contain fluorescent chemicals, markings made by markers will look eerily lit by themselves when placed in a dark room with ultraviolet light (such as a dark room).
Fluorescent inks are brighter in the visible spectrum than the visible light that originally existed. Fluorescent inks contain fluorescent pigments that absorb and reflect more light than normal inks.
In addition, although some of the marker inks may be acidic dyes, the addition of an acidic buffering agent in accordance with the present invention may further reduce image smearing during extraction. Although the dye is a vital ingredient, it makes up no more than 5% of the ink.
As with Horis’ invention, the ink was drawn by capillaries through a cigarette-like filter onto the surface of the paper as the writer pressed the marker against the paper. The marker comes with fast-drying, odorless ink to mark important information on notes, text, and documents. A highlighter is a type of writing device used to draw attention to sections of text by highlighting them with a bright translucent color.
