The invention relates to a method for producing a plurality of items (A) customized with visually coherent features, which includes the following steps: generating a plurality of unique decorative images each encoding a plurality of unique codes (Cx), each unique code 5 (Cx) being reconstructible through analysis of an image output from a digital camera of a communicating device that has captured a unique image (ICx), and each unique code (Cx) representing a unique address accessible, via a network, from said communicating device, and printing the unique decorative images on a plurality of respective items 10 (A) or on a plurality of substrates (Sx) intended to be attached to said plurality of individual or grouped items using a digital printing system. Items are thus mass-produced, making it possible for every item, without using an optical bar code or QR code, to access 15 content or a unique digital space, with customization possible.
