Advanced Print Head Technology
The Marsh 320Si printer’s new printheads combine advanced micro-valve and slant head technologies to provide higher resolutions of up to 40 dpi, precision drop placement and superior throw distance of up to 1.2 inches (30 mm). These printheads are also rated to run at 200 feet per minute (60 m/min.) at 40 dpi resolution. The precision manufactured micro-valves are designed to run with both water-based and fast-dry solvent-based inks, providing maximum flexibility. The printheads are rated at IP67 to withstand extreme environmental conditions in a
variety of customer applications. Slant technology enables one or two lines of print between 1/2 inch and 1 inch (12 and 24 mm) in height per printhead.

Slant Technology
The Marsh 320Si printer can print characters using fonts which are based on 7, 12 and 16 drops. The slant technology also enables such characters to be printed in messages which are between 1/2 inch and 1 inch (12 and 24 mm) in height. The micro-valves in this printer enable two lines of 7 drop high characters to be printed where other technologies only permit one line.

Throw Distance
The proprietary valves in the Marsh 320Si printhead operate at a higher frequency than those in printers with traditional technology, and the ink is output at a much higher speed. This makes the printer more robust in changes to throw distance, so it can print messages at throw distances of up to 1.2 inches (30 mm) or more, depending on line speed. Traditional technologies can handle throw distances of no more than 0.12 to 0.16 inches (3-4 mm) before print quality
degrades. This insensitivity to throw distance enables the Marsh 320Si printer to operate in applications where the substrate is irregular and when physical constraints limit close access to it.
