To Set Constant Print Speed - Weber Markoprint iJET Operating Manual

8.10 To set constant print speed

The print speed of the print heads must match the conveyor belt
speed; otherwise print images may be distorted.
There are 2 ways to match the print speed to the conveyor belt
speed:

Internal constant print speed

External variable print speed via rotary encoder
If no rotary encoder is connected to the controller, the conveyor
belt speed must be measured or estimated and the determined
value entered as a parameter. A test image can then be used for
fine-tuning the print speed.
The following parameters must be entered:

Print speed
Print speed = Conveyor belt speed. The conveyor belt speed
must remain constant!

Print intensity
Print image contrast. If necessary, this parameter may have to
be changed to optimise the print image to the product surface.
Higher intensity means increased density and slower drying of
the ink.

Zoom
This parameter enables an increase or decrease of the number
of pixels. This renders the print image wider or narrower.
The maximum speed is dependent on the set intensity:
At 600 dpi the print speed may be up to 30 m/min. Maximum
text length 1000 mm.
At 300 dpi the print speed may be up to 60 m/min. Maximum
text length 2000 mm.
At 200 dpi the print speed may be up to 90 m/min. Maximum
text length 3000 mm.
At 150 dpi the print speed may be up to 120 m/min. Maximum
text length 4000 mm.
A print speed 50% higher can be obtained with a rotary
transducer.
This setting lies outside the specification and must be carefully
tested!
A double speed can be reached with the High Speed function by
the iJET Pro version. At 300 dpi the print speed may up to 180
m/min. The text length is up to 3 times longer.
