Stick with Group4, you will be fine, we here at the US Patent & Trademark Office use Group4 compression, so it will be around forever probably. All of the patents that we put in digital format are in Group4 and are archived in that format.

I'm working in a digital preservation project for the Portuguese National Archive. Currently we need to migrate a bunch of images created in a previous digitization project to a new physical support. The images have 2 colors (Black and White) are in TIFF format with Group4 compression. These images are going to be stored in a safe way until 2013, preferably in TIFF format (with or without compression). My question is, should i keep the compression or not? I'm not sure if in 2013 software that can deal with that compression scheme (Group4) is going to be supported or not; and if i keep the compression, should i use Group4 or another?
