Types of Inks Compatible with Large Character Handheld Jet Printers

Large character handheld jet printers can work with various types of inks, each with its own set of characteristics and ideal applications. Let's explore some of the most common ink types used in these faith printers:

Pigment-Based Inks

Pigment-based inks are a popular choice for large character handheld jet printers, especially when printing on porous surfaces. These inks contain solid color particles suspended in a liquid carrier. Key advantages of pigment-based inks include:

- Excellent durability and fade resistance

- High opacity and contrast, even on dark surfaces

- Good water resistance once dry

- Ideal for outdoor applications or harsh environments

Pigment inks are particularly well-suited for printing on cardboard boxes, wood, and other absorbent materials. They tend to sit on top of the surface rather than being absorbed, resulting in sharp, crisp characters that are easy to read from a distance.

Solvent-Based Inks

Solvent-based inks are the go-to choice for printing on non-porous surfaces like plastic, metal, and glass. These inks contain pigments or dyes dissolved in a solvent carrier. Benefits of solvent-based inks include:

- Excellent adhesion to smooth, non-absorbent surfaces

- Fast drying times, even on non-porous materials

- Good resistance to water, chemicals, and abrasion

- Ability to penetrate thin layers of oil or dirt on surfaces

The fast-drying nature of solvent-based inks makes them ideal for high-speed production lines where print smudging could be an issue. However, it's important to note that some solvent-based inks may require proper ventilation due to their volatile organic compound (VOC) content.

Water-Based Inks

Water-based inks are becoming increasingly popular due to their eco-friendly nature and low VOC emissions. These inks use water as the primary carrier for the colorant. Advantages of water-based inks include:

- Environmentally friendly and safe to use

- Low odor, making them suitable for food packaging applications

- Easy cleanup with water

- Good performance on porous substrates

While water-based inks perform well on porous surfaces like paper and cardboard, they may not be the best choice for non-porous materials or applications requiring high water resistance.
