PrintEngine™ Offline
The ixPressia off-line tool allows printer developers access to the power of the ixPressia image pipeline when away from the printer

Print Engine Colour

ixPressia off-line is designed for ink jet printer developers.

It allows access to the full power of the image pipeline without needing to be attached to a printer. Instead it outputs bitmaps.

No need for external photo manipulation!

During the early stages of a printer development engineers often need to process images and then load them manually into the print head electronics. This is often a laborious and time consuming process. Typically the input image needs to be dithered, colour corrected, colour separated and then split into swathes for each of the printheads. This can take hours.

ixPressia off-line automates the process. It allows an image file to be read and then automatically does the full image processing (colour correction, dithering, splitting) and generates bitmap files for loading into the datapath electronics. Because the ixPressia PrintEngine™ knows about the location of the heads it generates the swathes for each head automatically.

Saves time

This automation can save hours of engineering time, particularly if the head layout needs to be changed, or if new test images for calibration or test need to be used.

Easy introduction to ixPressia technology

The ixPressia off-line tool is a modified version of the full ixPressia PrintEngine™, with the same full image pipeline. It is a great way to start using the technology. When you are ready you can upgrade to the full PrintEngine™ and automatically send the data straight to the heads.

DXF and Gerber | ixPressia

The importer option takes into account different resolutions in the X & Y directions – a situation common in many inkjet printers. If your application requires additional customisation this can be added as a custom feature to the ixPressia PrintEngine™. Conversion to bitmap based on printer resolutions in the X and Y directions. Other DXF and Gerber conversion tools don’t offer this functionality.


Licensing | ixPressia

The IxPressia PrintEngine™ Software is installed on the printers you ship and activated by an IxPressia PrintEngine™ Dongle. You have complete control over the features enabled and the controls available to the end user. You purchase the number of licences required for the number of printers manufactured. Discuss your requirements and spec with ixPressia team. Steps to IxPressia PrintEngine™ Success.


PrintEngine™ Mono Label | ixPressia

Data can be internally generated from counters (for barcodes, serial numbers, batch codes etc), or read from an external source. Our monochrome solution is based on the same advanced technology used in ixPressia’s colour variable data software. Design labels and save as a template file using the ixPressia label designer off-line from the printer. The ixPressia label designer is a simple to use layout package designed to run on a standard PC.
