The front side of the carbon paper is coated with an acid developer, and its back is coated with a colorless leuco dye. Therefore, when the carbon paper overlaps, the microcapsules will be ruptured due to the mechanical pressure, and the colorless latent dye overflows. Acid will be emitted and color will develop to form images. Carbon paper can be used for multiple sheets, and carbon paper is usually used as a ticket.
How to use carbon paper
Put carbon paper in the middle of two sheets of paper and write it on a sheet of paper. It can be transferred to the following copy paper by using carbon paper.
How to eliminate carbon writing?
Use a toothpick or other small object to stick with toilet water and follow the traces. The blue traces of the copy are gone. Or wipe very spirits with cotton balls and dilute absolute alcohol. And no traces.
Carbon paper principle
Carbon copy paper and its principle
The principle of carbon copy paper is to apply a material such as wax or stearin that is mixed with carbon or other coloring material. It can be used on pencils, pens, typewriters and the like and it can be written on our regular paper. Thin paper can be sandwiched and can be rewritten several times. The copied paper can be used to make a copy offset copy paper, and can be made into a back-up paper copy, and can also be printed in multiple copies. However, its disadvantage is that it is easy to contaminate clothes and fingers. It is very inconvenient.
Carbonless paper and its principle
Carbonless paper has another name, Limin Paper. Carbonless copy paper can be divided into two kinds of color development and self-development, but we use more often in his daily life colorless carbonless copy paper, which consists of three types of pages: upper, middle, and lower. The appearance of carbonless copy paper is the same as the white paper we use everyday. There is no difference in appearance, but carbonless copy paper is a kind of hidden color reproduction. Writing with a pen can directly develop color. The principle of carbonless paper is actually to rely on a chemical material reaction to achieve the color effect, that is, the reaction of the leuco dye and the color developer. However, in the past, carbonless paper was colored with wax, and today's carbonless paper reacts with chemicals to change color.
The above content is about the analysis of the principle of carbon paper and how to eliminate the writing of carbon paper. I hope that these contents will bring some help to everyone.
