In 1938, the American Chester F. Carson used cotton cloth to rub a zinc plate coated with sulfur on the surface in a dark room to charge it, and covered a transparent manuscript with an image on the plate to expose the non-image area of the plate. The charge disappears due to light, and the image area remains at the original potential without light, forming an invisible electrostatic latent image....
First, General requirements for pigment selection 1. Alkaline Most of the resin binders of water-based inks are alkali-soluble, and the selected pigments must be alkali-resistant. If the pigment molecules contain genes such as sulfonic acid groups and carboxylic acid groups that react with alkali, reactive condensation will occur. 2. Hiding power High-grade water-based inks require high hiding pow...
Structure: Polyurethane associative thickener is a new type of non-ionic waterborne polyurethane polymer. Its molecular structure is characterized by an amphiphilic polymer. The middle segment of the molecule is a hydrophilic segment and both ends are lipophilic segments. Thickening mechanism: In the water-based system, when the polyurethane associative thickener reaches a certain concentration, t...

Road safety. Pre 1920’s One of the earliest known applications of road markings can be traced back to ancient Mexico on a road near Mexico City sometime about 1600 A.D. The centerline was placed to separate opposing traffic and was created using lighter-colored stones in the pavement. In more modern times the first painted stop lines were in Portsmouth,Virginia in 1907. The first markings for cros...
There are many types of printed matter, and different printed matter often requires the use of different types of paper. The varieties and specifications of some commonly used printing papers are now introduced as follows: 1. Letterpress paper Letterpress paper is the main paper used for printing books and magazines on letterpress. Letterpress paper can be divided into four levels: No. 1, No. 2, N...
Acrylic resin is one of the most widely used resins in the world. Because of the different raw materials and preparation methods, thousands of products with different properties and different uses can be synthesized. Adhesives, coatings, and films synthesized by acrylic resins , Elastomers, medical materials, transparent materials, photosensitive materials, water-absorbent ...
Do you want to know what kind of resin is suiable for scerrn printing ink? After reading this artilce, I think you will know it clearly. Ther are many brands , many series of Solvent ink, but no matter which series are made up of resin, solvent, pigment, filler (or additives). At first we should know the solvent ink composition. Below resin are commonly used in screen printing ink: Vi...
Flexographic Print, also known as "Aniline Ink", it’s a direct letterpress rotary printing method, using a flexible raised image printing plate to provide a more flexible item Macromolecule synthetic rubber or new photosensitive resin is the plate material. The printing plate can be glued to the printing plate cylinder of variable repeating length. The printing plate is applied by a metal ink...
What are the white pigments commonly used in ink production? Titanium dioxide and lithopone are mainly used. Lithopone is a mixture of barium sulfate and zinc sulfide, containing a small amount of Zn0 impurities, and its molecular formula can be expressed as BaSO4.2Ns. In fact, there is no chemical combination between the constituent compounds in lithopone, and each of them exists independently in...
