Affinity Designer PSD Export in Affinity on Desktop Questions (Mac and Windows) Posted August 7 11 minutes ago, MikeW said: The printing company is smoking crack if they expect 300dpi. If the design is output at 100% size, they are going to print at a maximum of 150 dpi. And, using the Photoshop format, only the .psb format can contain a file that large at 300dpi. And it would need to be printed direct to their RIP which take a lot of time to process. That, printing direct using the .psb format, is doable with the right equipment, but I doubt they would actually do it as the RIP will do a great job with a smaller dpi (i.e., fewer pixels) anyway. These days, PDFs are generally used at a scale such as 50% of print size. In the case of say a desired output of 150dpi at full scale, one would then use a document of 300dpi, which once the pdf is doubled in size to 100% would make the images/bitmap effects to be 150dpi. Thanks very much for the info.
