A method of, and system for, producing a greetings card comprises capturing handwriting as a digital image, processing the digital image to extract the handwriting, combining the processed image with one of a number of images for the greeting card, and controlling the display of the combined image on a user device or the printing of the combined image. The system may include a networked server arrangement wherein the server controls the digital processing of the image and display and printing and the extraction may include applying a smoothing filter, e.g. Gaussion filter, to the digitised image, generating a colour or luminance histogram, applying thresholding to distinguish the background and deleting all the pixels that fall within the background threshold.
