3.4 Basic parameters for Print height, Stroke distance and Speed
The tables in this chapter provide recommendations for several parameter settings. Working with the
tables the following points should be considered:
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 at 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.
