理光G5s喷头介绍
转载自：喷印技术
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.
