Details on Affinity Publisher
Affinity Publisher is a winner of Apple’s “Mac App of the Year” award and a professional, perpetual, desktop publishing (DTP) Mac/Win app for creative designers. It supports PSD, AI, PDF, JPG, TIFF, PNG, and more file types and seamlessly integrates the Affinity Designer vector design software and Affinity Photo image editing software.
Owners of Affinity Designer and Affinity Photo can click the corresponding icon in Affinity Publisher, to use their app in a .afpub layout file. This allows for streamlined use of any combination of these three Serif apps.
Publisher is available now for download at the Mac App Store or via the Publisher page on Serif’s website. Since it is a one-time purchase, this Adobe InDesign alternative saves Creative Cloud users from subscription requirements and costs.
