Hello,

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?

Best regards,
Rui Castro
