Printing techniques of printable kraft gummed paper tape

Printable kraft gummed paper tape is a kind of kraft paper tape. Logos, patterns, etc. can be printed on it. So what are the printing techniques of printable kraft paper tape? Today, Baijin kraft paper tape manufacturers will introduce to you.

1. First of all, pay attention to the color of printing. Since ordinary kraft paper itself is dark brown, the effect of printing ink is very different from the effect of printing on bleached paper.

Therefore, it is recommended to use brightly colored inks and use more eye-catching colors, so that the printing effect is better. Soft colors and light colors are difficult to achieve the desired ink density, opacity, and abrasion resistance.

In addition, if necessary, a little white can be added to the ink first, which will help achieve the desired soft tone or light color.

2. Reasonable selection of ink, flexographic printing is generally better, and it is not suitable to use an offset printing machine. Because the surface of kraft paper is rough, the texture is soft, and the ink absorption is strong, the color of the printed product is not light, and the ink will pull down the fibers of the paper when printing.

3. When copying paper manufacturers are making cardboard, because the kraft paper without glazing is loose, porous and bulky, it is easy to generate dust during the cardboard manufacturing process, so pay attention to prevent and reduce dust. The harm.

4. Post-press die-cutting processing, due to the special structure of the primary color kraft paper, its strength is greater, and the fiber characteristics can be predicted, so it has better processing properties such as embossing, die-cutting and die-cutting, but for high-strength and tough primary colors For fiber, kraft paper is required to pass through a deep indentation line to avoid rebound.

5. Resin adhesive with reasonable gluing, high solidity and high viscosity is suitable for low-temperature bonding. It needs to be cooled before it can be attached to the kraft paperboard. It cannot penetrate the paperboard in large quantities. The traditional hot melt adhesive is also suitable for kraft paperboard Polyester-glazed kraft paper has a better effect. Because of its lighter weight, kraft paperboard is suitable for production on high-speed box gluing machines.
