The present invention provides dual energy imaging compositions, processes for forming dual energy imaging compositions, methods for forming images using dual energy imaging compositions and substrate treated on one or both sides with a dual energy imaging composition. The method and system enable a user at the remote first computer to secure a data file for storage by connecting to the second computer and by exchanging certain parameters between the two computers. The method further discloses setting the first component flag to busy, setting the turn flag to first component, and performing the first function when the second software component is not using the PCI device.
