UV LED local dimming control

A considerable boost in productivity, as well as a reduced risk of dust contamination of glossy print areas.
The XpertJet 461UF and 661UF direct-to-object printers are equipped with a newly developed segmented 5 cm (2 ”) wide UV lamp. The UV lamp has 6 different sections. Each section of the lamp can be individually controlled, allowing the production of multiple varnish effects in a single pass.

Varnish gloss, semi-gloss or matte effects can be produced in a single pass for prints that combine CMYK + varnish or white + varnish. The result is a considerable boost in productivity, as well as a reduced risk of dust contamination of glossy print areas.

VerteLith ™ - Authentic Mutoh RIP Software

A complete and compact printing solution with advanced support for all 6 conduits to easily handle a wide variety of printing tasks, including multi-layered graphic jobs that require white and / or varnish layers.
VerteLith ™ software is built around the Harlequin server processor, ensuring fast RIP processing times for PDF and PostScript files, as well as flawless handling of transparencies and selective colors.
To avoid waste, the software includes powerful preview functionality, supporting on-screen color proofing and RIP previewing of actual printed dots before printing.
By integrating halftone revision specifically developed for inkjet, Mutoh's VerteLith ™ Clear Tone will produce the best possible gradients and skin tones.
To complete the software's beginner's toolbox, VerteLith ™ can also automatically generate white or varnish layers based on pre-selected settings and allow you to calculate the cost of ink before printing.
The result can be perfectly prepared for the next step in the production process with the finishing tool set, which allows flexible layouts and markings for cuts or perforations.

Piezo Head Technology, how does it work and what are the benefits?

Piezoelectric and drip-on-demand print heads were introduced to large-format printers in the 1990s, greatly expanding the applications and opportunities for large-format users. It meant that, at last, solvent and UV-cured inks originally associated with screen printing processes could now be digitally printed. Thermal print heads that had previously been the only technology available for large format printers could not accommodate these types of ink. It was a revolutionary development for the industry.

The science

Piezoelectric heads work through the expansion and contraction of a piezoelectric crystal (usually lead zirconate titanate, known as PXT) located at the back of the ink reservoir. Glass expands and contracts (or flexes) when an electrical current is passed through it. So every time a dot is needed, a current is applied to the piezoelectric crystal which flexes and in doing so forces a drop of ink out of the nozzle.

Since electrical current can be turned on and off instantly, glass expansion / contraction is just as instantaneous, so there is much more scope to control dot formation than with thermal heads.

Many piezoelectric heads are known as "drip on demand" heads. Drip-on-demand heads are the type most commonly found in modern wide-format printers. Drip on demand means that inkjet nozzles generate and project ink droplets when and where they are needed to produce a mark on media.

Piezo heads can also generate variable size droplets from the same chamber and nozzle, providing different ink densities on the material. Most can produce ink droplets as small as 1.3 picoliters. This technology provides the user with the highest ink precision for detailed jobs such as photography, artwork and small text, as the ink droplets provide a sharper, grain-free print with smoother tonality transitions. They are called grayscale heads.

Because the print heads are integrated into a transport that travels back and forth at certain speeds and accelerations, it is not always possible to use all the possible drop volumes of a print head during the printing process. The reason for this is that jet drops are also subject to turbulence during travel, influencing their travel path.

Advantages of piezoelectric heads compared to thermal print heads

  • No heat is used to expel the drops. Heat can change the mechanical composition of the ink.
  • Piezo heads are compatible with a wider variety of ink types and ink ingredients
  • The user has access to a wider number of applications
  • Heads are more durable than thermal heads and need to be exchanged only infrequently. Sometimes they can even last the life of the printer, if they are well maintained.
  • Provides precise and variable drops, saves ink waste.

History of Mutoh with piezoelectric head technology

At Mutoh, we've been integrating on-demand piezoelectric inkjet technology into all of our large-format UV, solvent, and water-based digital inkjet printers since 1999. We know piezoelectric inkjet technology from foot to foot! head!

The key to our success has been the development of dedicated inks suitable for specific piezo heads, covering specific applications. Mutoh's leading market since 2006 has been our intelligent Interweaving (i²) technology. With this technology, the ink is placed in a "wave pattern", offering a perfect, sharp and consistent quality of the final product without compromising print speeds.
