Tips You Need to Know Before Buying a MEIXI UV Printer

03/23 2022

When you are buying a new UV flatbed printer, you should ask some basic questions about its print head.

First, is this printhead designed for solvent inks, or is it designed for UV inks?

Some printheads are not made to print UV ink. Early model Epson printhead is an example, when Epson itself does not produce UV-curable printers, Epson only produces water-based and solvent-based printers for photo printers and artwork. This does not mean that they cannot spray UV-curable inks, it just means that the printheads may require special inks. Therefore, this question helps you understand whether the printheads are designed from the ground up for printing UV inks.

Second, what is the total number of printheads in the printer?

There are single-color printheads where one printhead can only print one color, and there are multi-color printheads where one printhead can print multiple colors.

Ricoh GEN5 printhead, for example, it has two channels and four channels and other different models, when used on the machine, you can print a printhead only one color, you can also print a printhead two colors (two channels and four channels can be), you can print a printhead four colors (four-channel printhead).

Third, is there a special white ink or varnish printheads? Are they the same type as CMYK printheads?

Since the use of larger nozzles can make white ink better, so some printers only have white ink “white ink drop size favorable.

Fourth, if this piezo head fails, who is responsible for paying for a replacement head? What are the common causes of print head failure? What causes of failure are covered by the warranty? What causes of print head failure are not covered by the warranty? Is there a limit to the number of print head failures covered per unit of time?

If the failure is caused by user error, most manufacturers will require the user to pay for a replacement print head. Most failures are indeed user error, and a common cause is head impact.

Fifth. What is the printhead print height? Is it possible to avoid printhead impingement?

Head impacts are a common cause of premature printhead damage (improper media loading, which can lead to bending, media rubbing against the delicate nozzle plate, or not passing through the printer properly). A single head impact can damage only a few nozzles, or it can damage the entire printhead. Another cause is the continuous flushing, flushing can damage the nozzle system.

Six, how many picoliters of printhead ink droplets are there? Is there a variable droplet capacity?

The smaller the droplet, the better the print quality. However, smaller droplet sizes can reduce the speed of the printhead system. Similarly, print heads that produce larger droplet sizes do not provide the same print quality, but tend to print at better speeds.
