Transfer assemblies and transfer sheets and release paper for transferring images to articles, such as textiles, fabric or the like, are provided. In addition, improved methods for manufacturing the transfer sheets and the articles are provided. A transfer sheet comprises a support layer and an image transfer layer that includes an ink receptor and a blocking agent. The blocking agent is configured to block or impede the transfer of the ink composition to the substrate in non-printed areas of the image and substantially allow the transfer of the ink composition to the substrate in printed areas of the image. The systems and methods described herein provide a single step process that is “self-weeding”, while minimizing defects in the image that is printed onto the article and are particularly useful for transferring white or colored images to dark colored or black textiles and other fabrics.
