A printed article 1 comprises a substrate 2 and an image 3 printed on the substrate. The image includes line art 4 formed of conductive ink. The image includes representations of at least two items (61, 62) which overlap such that line art of a first item is joined at least at one point (71) to line art of a second item. This avoids the conductive tracks crossing the image allowing a circuit to be formed without spoiling the visual appearance of the article. The printed article can be a book, a greetings card, a postcard, a poster, a calendar, packaging, a board game, a folder or file, an in-store display, a promotional item or wallpaper. The circuit can include discrete electronic components and light and/or sound emitting devices. |
