Magnigraph is and easy-to-use web-based application that allows you to convert photos or sketches into black and white negatives for printing T-shirts, mugs, posters or anything else. To create a Magnigraph, either upload an image from your desktop or point Magnigraph to the web location of the images by cutting and pasting the URL. In seconds your image will be converted and ready for using to create unique gifts. Magnigraph works best with low resolution, high contrast images so keep that in mind if you are looking to get the best results. Once you’ve converted the image, you can also select to display it in red, blue, or black.
