drop on demand inkjet printer

Types of Drop-on-demand Inkjet Printers

There are several types of drop-on-demand inkjet printers, and each one is designed for a specific function. This ensures that there is a suitable printer for any application, ranging from simple home use to complex industrial printing.

Thermal Inkjet Printers

These printers work by creating a small bubble of steam in the ink chamber, which is usually achieved by a resistive element. Once the bubble bursts, it forces a drop of ink out of the nozzle. These printers are usually found in consumer-level printers and are suitable for photo printing. They are also used for printing labels, texts, and images.

Piezoelectric Inkjet Printers

Piezoelectric printers use a piezoelectric crystal to deposit ink. These crystals change shape when an electric current is passed through them. This generates pressure within the ink chamber that forces the ink out of the nozzle. There are a wide variety of these printers, and they are usually found in industrial settings. This is because they can use much thicker inks and are also more durable.

Continuous Inkjet (CIJ) Printers

These printers constantly circulate ink through the nozzles. The ink is then charged and drops are ejected onto the substrate, while unused drops are recirculated. These kinds of printers are mainly used for high-volume, commercial applications, such as packaging and coding products. CIJ printers are ideal for printing on uneven or flexible surfaces.

Linear Edgejet Printers

This printer is best suited for large, flat surfaces. The main benefit of this printer compared to CIJ printers is that it is much more affordable and easier to maintain.

Quality and Safety Considerations of Drop-on-demand Inkjet Printers

Ink Quality

To achieve high-quality results, always use high-quality inks that suit the printer's technology. This is especially true for water-based inks, as low-quality ones will cause the printer to jam often and produce constantly faded prints.

Then again, using premium-quality ink will ensure that images come out sharp with true-to-life colors and that the ink will be long-lasting. The printed materials will be very clear, premium-quality images. It is also advisable to frequently check ink levels and replace cartridges as soon as they are empty. Don't wait for the ink to be finished before replacing it, as doing this will cause the print head to dry and crack. It will also cause a blockage in the printer nozzle.

Printer Head Maintenance

Print head maintenance is essential for ensuring that the drop-on-demand inkjet printer functions efficiently. Regular maintenance like cleaning prevents ink from drying and clogging the nozzles. Also, users should follow the manufacturer's guidelines for cleaning procedures and use any provided maintenance kits. Avoid using harsh chemicals that will damage the printer or adversely affect the printer head's internal components.

Environmental Considerations

When choosing the inks to use in drop-on-demand printers, it's best to go for eco-friendly options. These inks are usually called water-based or vegetable-based inks. They are less harmful to the environment and don't contain harsh or harmful chemicals that will negatively affect the person using them. The manufacturers of the printers should also be using sustainable manufacturing practices. This is to ensure that the impact of this entire device on the environment is minimal.

Another thing that needs to be done is proper disposal of the printer's components. For instance, the ink cartridges and print heads should be recycled or disposed of as instructed by local electronic waste regulations. This prevents toxic substances from harming the environment.

Safety Precautions

When operating the printer, always ensure that the power supply meets the manufacturer's specifications. Using the wrong voltage can cause the printer to malfunction and, even worse, start a fire. Always place the printer in a location where there is sufficient airflow near the ink cartridges. This is especially true for printers with solvent-based ink, as the solvent may escape into the environment. Excess accumulation of inks will lead to an explosion.

Next, before replacing ink cartridges and other printer parts, ensure the printer is turned off. Wait for it to cool down as the internal parts may be extremely hot, and handling them will cause burn injuries. Lastly, always wear gloves and masks when handling inks and cartridges. This is because prolonged exposure can lead to skin and respiratory irritations.

But Consider These When Shopping on

When selecting a drop-on-demand inkjet printer, buyers should consider several factors that will help them receive printers that will perform at an optimum. Here are some of those factors.

Print Quality

This is the first thing buyers need to consider. Printers that have various settings are able to produce prints of different qualities so they can test the printer quality before doing anything else. Buyers will also need to check the DPI. As stated before, DPI means resolution. The higher the resolution, the printer will produce clearer prints.

Print Speed

These printers allow buyers to manage printing speed conveniently. It means if there is lesser printing speed, the quality will be much better, and vice versa. If a print speed is low, find a way to increase it, and if it is high, find a way to decrease it so that the quality will be at its finest.

Ink System

There are two main ink systems in these printers: cartridge and continuous ink supply system (CISS). Each of them has its advantages and disadvantages, so it's important to weigh them carefully. Cartridges are easier to replace, whereas CISS is more economical in the long run.
