A scientific poster is usually printed on a huge paper format (A0 or A1) containing text but mainly figures that should present a scientific topic in a consolidated yet interesting and self-explaining way.
Several software packages can be used to produce a poster. The ones I have some experience with are Adobe Illustrator, Photoshop and Latex (beamer and tikz packages - this is a good starting point if you want to write a poster with latex). And I usually end up using Latex, thinking that there should be an easier way to create a scientific poster.
So, I'm wondering, is there a software that just does posters? Or what is the best option (software wise) to produce a scientific poster?
