Main printing methods

Since China invented woodcut movable type printing technology, printing methods have changed with each passing day. The most commonly used industrial printing methods today are:

offset printing/lithography

Offset printing, also known as offset printing in Guangdong and Hong Kong, is a kind of lithography and the main printing method. Offset printing can clearly restore the color, contrast and level of the manuscript with high precision, and it is the most commonly used paper printing method at present. Suitable for posters, brochures, brochures, newspapers, packaging, books, magazines, calendars and other related color printed matter.

Flexographic printing

Flexo printing is a relief printing technology, which used to be called aniline printing. Rubber and soft resin are used as printing plates, and water-soluble or alcohol-soluble inks are used for printing. The pigment used at first was aniline dye, so it used to be called aniline printing. It is usually suitable for printing plastic bags, labels and corrugated paper. The fineness of printing points and lines gradually approaches offset printing.

Flexographic printing is mainly divided into unit flexographic printing and satellite flexographic printing. In the past, unit flexographic printing was mainly used in China. Now the application of satellite flexography is more and more extensive. The main advantage of satellite flexographic printing is that it can accurately control the tension of the substrate.

silk-screen printing

As a widely used printing method, screen printing can be divided into fabric printing, plastic printing, metal printing, ceramic printing, glass printing, electronic product printing, lottery screen printing, electronic decorative billboard screen printing, metal billboard screen printing, stainless steel finished screen printing, reflective screen printing, screen transfer anodizing, screen printing printed matter and lacquer screen printing.

As one of stencil printing technologies, printing ink is particularly thick, which is most suitable for making special-effect printed matter. It is especially suitable for small quantities and ink colors need to be concentrated.

It can also be printed on solid surfaces, such as square boxes, boxes, round bottles and cans. Besides paper, you can also print cloth, plastic fabric, plywood, film, metal sheet, glass and so on. Common new products include banners, pennants, T-shirts, corrugated boxes, soda bottles and circuit boards. The flexibility of screen printing is incomparable to other printing methods.

intaglio printing

It is suitable for printing high-quality and expensive printed matter, whether it is color or black-and-white pictures, and the gravure printing effect can be comparable to that of photographic photos. Because the cost of plate making is expensive and the printing volume must be large, it is generally one of the less used methods. Suitable for printing securities, stocks, gift certificates, commercial credit certificates or stationery.

With the rapid development of science and technology, today we can use some of the above printing methods to output directly on the medium through the computer. The maturity of electrostatic imaging and laser technology makes it possible to print on demand in small batches with high quality requirements.
