1 Sure. Father's Day is a holiday honoring fathers and celebrating fatherhood, paternal bonds, and the influence of fathers in society. It is celebrated on the third Sunday of June in the United States, Canada, the United Kingdom, Ireland, Australia, New Zealand, and several other countries around the world.

After the ink is dried and solidified on the substrate to form an ink layer or ink film, due to friction, ink layer not fully cured, poor adhesion, etc., it is transferred to other places through contact or scratching, causing pollution, which is called "Ink Migration".

Optical variable ink (OVI) and solar photosensitive ink (SPI) are both types of security inks that are used to prevent counterfeiting. OVI inks change appearance when viewed from different angles, while SPI inks change appearance when exposed to ultraviolet (UV) light.

Label printing is the process of creating labels with text, images, and other graphics. Labels are used to identify, track, and market products and services. They can be found on a wide variety of items, including food, clothing, electronics, and medical supplies.

Print Area taken part in the South China Printing Exibition and 5th International Printing Exhibition in Dongguan.So we decided to hold a meeting to discuss and summarize the work in March and April.

Optically variable inks were first used in the anti-counterfeiting printing of banknotes, checks, bonds and other securities. With the continuous development of science and technology, optically variable inks are not only used for anti-counterfeiting printing of trademarks, but also for surface decoration of special products. The reason why the optically variable ink has the corner-changing color characteristic is that a pigment with a very special structure is used, and its particles are very thin flakes with a good particle size distribution. The production process of the pigment is as follows: under high vacuum conditions, according to the design requirements of a specific film structure, a variety of materials with different refractive indices are sequentially deposited on the same carrier to form an optically variable film, and then undergo crushing, grading, surface treatment, etc. . When the thickness of the film layer meets the interference conditions of light, the film layer will show a photochromic effect, that is, its color will change as the viewing angle of the human eye changes.

Ultraviolet-excited fluorescent anti-counterfeiting ink is an ink made of inorganic pigments or organic dyes that can be excited by ultraviolet light to display colors, called fluorescent inks (or invisible inks). Its manufacturing method is to add the pigment (dye) to a certain proportion of resin oil linking material, filler, stabilizer and desiccant, and process it with an ink-making three-roller mill.

Flexographic printing is a type of letterpress printing that uses a flexographic printing plate and transfers ink through an anilox roller.
