Product packaging printing technique using flexographic printing.

What is flexographic printing on product packaging?

Flexographic printing  is a relief printing method, also known as direct-to-packaging printing. The printing elements, including images and text, are raised above the non-printing elements on the printing plate. The printing plate's content is determined by engraving in the reverse direction (unlike sheet-fed printing) or in the same direction (like roll-fed printing). Ink is supplied by an anilox roller, and then transferred directly onto the packaging surface during the printing process. Flexographic printing is only suitable for inner packaging, simple block images, and non-interactive text.

Flexographic printing technology is widely used and has great potential for development due to its ability to fill large-scale production systems and its capability to print on automatic labeling machines.

Flexographic printing technology

Flexographic printing technology uses printing plates made from soft materials such as rubber or soft polymer compounds in the form of individual pieces or sheets. The printing plate is manufactured by laser engraving. It is then attached to the printing plate's cylinder so that the printing plates are aligned. The choice of rubber or polymer printing plate depends on the packaging design file, color compatibility, and the quantity of packaging.

Common errors when printing product packaging using Flexo technology.

1. Ink sticking: due to changes in pressure and temperature.
2. Ink smudging: Lines appear around the edges due to the use of the wrong ink.
3. Due to air bubbles in the ink, the spraying is uneven.
4. Spotted print: Spots or lines appear on the printout due to uneven ink distribution.
5. Ink overflow, large print: Due to excess ink at the edges.
6. Poor ink transfer: Due to poor ink adhesion.
7. Ink loss due to poor ink transfer or adhesion: This is caused by poor ink transfer and adhesion.
8. Bleeding: The color after printing is much darker than the original color, and the original color hasn't dried yet.
