The main types of ink used in today's printers

Offset printing inks (or news inks) are the main inks used in newspapers, telephone directories, etc. They consist of carbon black and adhesives, unless color pigments are required. They are ideal for publications.

Liquid inks, mainly flexographic and gravure printing inks, are the leading technology in packaging. Flexographic printing is the leading process. Flexographic and gravure printing machines are roll to roll printing machines. Depending on the substrate and application, inks cover all fields of water-based, solvent based, and UV technology.

As for the composition of liquid ink, the main difference between paste ink and liquid ink is the type of resin and additives. Paste inks will use hydrocarbon resins, while liquid inks will use acrylic, nitrocellulose, polyamide, and other types of resins.

Digital printing is the fastest-growing field in printing. It has occupied the market previously dominated by screens (billboards, tiles) and offset printing (direct mail). It is also growing in markets such as textiles and folding cartons, and digital ink has also expanded to the corrugated paper printing market.

In the past twenty years, energy curable inks have made great progress in packaging and digital printing. These are broken down into ultraviolet (UV), electron beam (EB), and more recently ultraviolet LEDs, whose use is growing rapidly because they do not require mercury based lamps used in traditional ultraviolet light.
