1 Introduction
The new High Speed Line from LEIBINGER provides several solutions for high speed applications.
The High Speed Line comprises two groups of printers:
oThe JET Rapid printer as a solution for general high speed applications.
oThe JET Rapid Wire printer for applications especially in the cable/wire/tube industry
This document provides:
oTechnical data
oDifferences between the features and the possible applications of the printers
oOverview on the available inks
oImportant information about recommended encoders
oOverview on the differences regarding the spare parts
The first chapter describes the JET Rapid printer for general high speed applications; the second
chapter provides information about the JET Rapid Wire printer.
Important Information
There are several significant differences between the JET3up and the printers of the JET Rapid series.
The differences affect parts of the printer as well as service procedures.
It is highly recommended thoroughly checking the manuals and the
accessories catalogue for the differences between the JET3up and
the JET3 JET Rapid series.
The following list gives an overview about the parts that are different for the JET Rapid series in
comparison to the JET3up:
oController board
oParts of the Print head (please see details in accessories catalog)
oInk valve (VV)
Regarding service and adjustment procedures the main differences are:
oHydraulic settings
oInk jet adjustments
The differences are described in the manuals that come together with the printers.
There are extracts of the manuals in the addendum of this document.

2 The JET Rapid printer
2.1 General description of the JET Rapid printer
The JET Rapid comes with the SK6 print head of the JET3up. The main difference to the JET3up is
the higher oscillator frequency, which provides more drops per second.
With an oscillator frequency of up to 128 kHz the JET Rapid allows a 30% faster operating speed than
the JET3up that works with an oscillator frequency of 96 kHz.
The JET Rapid provides the same print modes as the JET3up. Therefore, the JET Rapid printer is the
best solution for high speed applications where the quality of the printouts of the JET3up is not
sufficient.
If, for instance, a print job for the JET3up printed with the 32-dot high quality print mode allows a
printing speed of 30 meter/minute, it will be possible to print the same job with the JET Rapid at a
speed of around 40 m/min.
In order to reach a good quality for the printouts at the faster speeds the recommended distance
between print head and substrate is 15 mm.
The print head of the JET Rapid: the print head has the same dimensions as the SK6 print head of
the JET3up.
The JET Rapid works with the same print modes as the JET3up. Due to the higher operating
speeds, the recommended distance between print head and substrate is 15 mm.
Shorter distances bear the risk of contaminating the print head; larger distances may have a
negative effect on the quality of the printouts.
Recommended:15 mm
43 mm
212 mm

2.2 The Speed Plus option
The SPEED PLUS option for the JET Rapid comes with a special Speed Plus print head, which
provides single line printouts up to a speed of 800 m/min.
With the special design, it is possible to mount the print head in a slightly inclined position. This will
prevent the printer from contaminations by bursting ink drops.
The print head of the option SPEED PLUS: The slightly beveled surface of the head cover allows an
optimized mounting of the print head.
Ink drops that hit the surface of a substrate tend
to burst in smaller drops and the substrate will
not absorb all drops
With a vertically mounted print head, the
bursting ink drops may lead to a faster
contamination of the print head.
With the beveled surface of the outlet of the print
head, it is possible to mount the print head in a
slightly inclined position.
The ink drops will not hit the substrate at a 90°
angle. Therefore, the bursting ink drops will take
a direction away from the outlet, which will lead
to less contamination of the print head.
Generally: the distance between print head and substrate should not be below 5 mm in order to
avoid the contamination of the print head by rebounding ink drops. A larger distance may have
negative effects on the quality of the printouts.
Recommended: 5 mm

2.4 Basic parameters for Print height, Stroke distance and Speed
2.4.1 JET Rapid
The JET Rapid provides the same print modes as the JET3up. The recommended printing distance is
15mm. There are no special recommendations regarding the settings for the print height.
The print mode selected has a direct effect on the maximum printing speed. However, the JET Rapid
provides a 30% higher printing speed in comparison to a JET3up with the same print mode settings.

Print modes
This column shows the print modes available for the JET3up JET Rapid Wire and JET3up Wire PI.
The speed modes work with one dot less in full strokes.
The small modes place the dots closer to each other than the standard modes.
A combination of speed mode and small mode has the same height as the small mode and one dot
less in full strokes a the speed mode.
Examples for print modes standard, speed, small and small speed with example character <H>:
5x5 dots
5x5 dots speed
5x5 dots small
5x5 dots speed small
Height [mm]
Height in [mm] shows the height of the printout that can be expected if the operator follows the
recommendations for the distances between print head and substrate.
Print height setting [% PH]
The minimum value of the print height settings ([PH in %] is important. A value below minimum may
cause contaminations at the gutter that will affect the quality of the printouts.
Recommended Stroke distance
The setting of the stroke distance has to correspond with the maximum speed that is expected for the
job. A value too small for the actual printing speed will cause StrokeGo errors. A value too large may
have a negative effect on the quality of the printout.
The values in the table are minimum values for the corresponding print modes and speeds.
For instance:
Working with the 5x5 dots print mode the minimum value for the stroke distance at a speed of 800
m/min is 0,62 mm. For the same print mode at a speed of 260 m/min the minimum stroke distance is
0,2 mm.
The basic rule reads as follows:
With increasing speeds, the stroke distance has also to be increased.
Please consider also that stroke distances below 0,25 mm are more theoretical values. Depending on
the ink and the substrate on which is printed the diameter of a ink drop on the substrate may already
have a diameter of 0,25 mm. In such cases the ink drops may overlap.
Speed [m/min]
The values in each cell of this column are neither minimum values nor maximum values.
The smaller value shows the boundary to the JET3up JET Rapid or JET3up printer. Printers of these
types may better cover applications working at printing speeds below these values.
The higher value is a speed recommendation for the corresponding print mode. Technically, it is
possible to work at higher speeds. However, the higher the printing speed the more the printing quality
is affected negatively.
