UV喷码机之理光G5喷头介绍

我们所用的UV喷码机,很多都是采用是理光G5的喷头,理光G5s喷头,也叫理光MH5220喷头,是理光于2016年5月发布的一款工业喷头。

理光G5s喷头主要功能包括:

一、在4 x 320喷嘴中配置了1,280个喷嘴,打印头实现了高分辨率,没有墨点的颗粒状外观,并且能够以多个打印头交错配置打印1,200 dpi分辨率。

二、多墨滴功能可以创建从2.5到9pl的各种墨滴尺寸。(请注意,采用多墨滴技术,墨滴快速连续喷射,然后在到达介质表面之前在飞行中合并)。

三、不锈钢结构,耐用,使用寿命长。

四、内置加热器,能够喷射高粘度油墨。

五、兼容UV耐用墨水,用于标签打印。

Characteristics
Drop size of 2.5pl and Single-pass 600dpi
high-resolution printing and support for multiple ink colors

2.5pl drop size allows excellent print quality without graininess.With 1,280 nozzles configured in 4 x 150dpi rows, this head achieves high-resolution 600dpi printing. Additionally, the ink paths are isolated, enabling a single head to jet up to two ink colors.

Support for grey-scale
Achieves excellent gray-scale rendering at up to 4 levels.

*Although controls for up to 4 scales are provided, actual jetting depends on ink characteristics.

Excellent durability
and extended service life
Ricoh inkjet print heads are made of stainless steel. These heads are highly robust and offer excellent anti-corrosion properties for multiple inks, resulting in excellent durability and extended service life.

Support for different inks
With its built-in heater, these heads are capable of jetting high-viscosity inks. Additionally, the ink path is isolated from the actuator (piezo elements) , i.e. no ink contact.

Variable drop volume capability
Ricoh’s open waveform policy allows tailored multi-drop printing of between 2.5 – 9pl, enabling high quality grayscale printing.
