Food Bag Printing Technology - Printing And White Ink Technology
Dec 24, 2018

The printing technology in food packaging bags has white ink technology, which brings unlimited possibilities. It is possible to turn labels and packaging on transparent materials into reality. For the production supervisor, for the designer. It is now possible to abandon the previous practice of printing on white paper with dark ink and then leaving the text or image area that needs to be rendered. However, printing text or image elements in white ink still faces many challenges, such as Registration problems, whether on digital presses or offset presses, have not found a satisfactory solution.

 

Digital technology has become a hot topic in the printing industry in recent years. Computer companies like Hewlett-Packard are also participating in the printing market with their energetic inkjet web presses. Today, print and publishing companies around the world are gradually forming three camps: early adopters of digital technology, supporters of offset technology, and creators of the combination of digital and offset technology. So, with the passage of time, what new markets or hotspot technologies are worth watching in today's printing industry? Let me check them one by one.

Printing Technology

Since its inception, it has been placed on the market to fill the gap between offset printing and digital printing. The way of working is such a printing technique in which Lanta ink is injected into the print head and invented by the father of digital printing, Benny Lanta. This is an aqueous ink containing graded pigment particles. When printing, the ink is transferred to a heated blanket and then transferred to the substrate. The compatible substrates are mainly coated or uncoated paper, plastic packaging film or label without special treatment. Paper, etc.

 

The properties of many materials change. The performance of the ink in this respect is very good. Due to the hard texture, the biggest advantage of printing technology lies in its ultra-small ink particles. After reaching the size of the level. This ink is extremely resistant to abrasion and scratches. The ink absorbs more light and therefore provides a wider CMYK color gamut. In addition, tiny pigment particles can make the ink film more uniform and the image sharper.

 

The moisture contained will evaporate once the ink is transferred to the heated blanket. And leave an ultra-thin ink film. So people don't have to wait for the ink film to dry—which is common in offset and digital printing—and go straight to the next production step. In addition, printing allows users to print more colors in the print area without over-saturation. The ink can be printed in up to 8 colors with a resolution between 600dpi and 1200dpi and a speed of 200m/min on the press.

White ink technology

Food packaging printing Fortunately, with white ink technology, printing white text or patterns on a dark background has never been a simple matter. The more opacity is determined by the number of ink drops ejected by the printer, the more white ink drops the printer uses, and the more opaque the printed text or pattern. Although it is more expensive, it can give users a better visual effect.

 

The device can control the printing effect by adjusting the number of drops of the ink jet during one pass. The offset printing process, the digital printing process. To get the same print results, the user must print at least 5 times on the same substrate. Although the emergence of "white ink" technology provides a cheaper solution for white foil, silk printing or plastic thermal transfer printing, its texture and feel are still inferior to manual processing. In short, the biggest feature of this technology is the ability to print different visual effects by controlling the number of ink drops ejected from the printer, especially on a variety of color substrates.
