The described embodiments relate to methods and systems for developing an electroluminescent sign. In particular, described embodiments relate to methods and systems that process an image file to generate data for use in developing the electroluminescent sign. Further embodiments relate to an electroluminescent sign developed and/or produced in accordance with the described methods and/or systems. Certain embodiments relate to a method of developing an electroluminescent sign based on an image file. The method comprises processing the image file to generate image data representing at least one illuminating image layer and electrical configuration data, transferring the at least one illuminating image layer onto a substrate and configuring a luminescence controller of the electroluminescent sign based on the electrical configuration data. The configured luminescence controller cooperates with the substrate to provide a luminescent image based on the image file.
