poster maker
 

I found a program a while ago that took any image and used dithering and whatnot to blow it up so you can print it on like 100 pages to make a giant poster withit.

anyone know what I'm talkin about? I can't seem to find it again

Yeah, Rasterbator

Is there anything like this that can do high quality posters?

awesome thanks

Well, large is generally mutually exclusive to high quality. Look at billboards. They are VERY large, and are actually VERY VERY rasterized. If you look at them up close, the look like nothing interesting at all.

I'm thinking of architectural presentations sizes, like 24"x36". I have photoshop but I don't see an option for printing tiles like the program above has.

Anyone know how to do this?? I also have corel draw and quark.
