This question already has an answer here:
I was commanded by the administration to create a billboard-sized design for our marketing advertisement but this method is newly introduced to me as a graphic artist. My problem is that it's a 20x20 ft and I don't know the proper requirements for it not to be pixelated if printed. Here are my following concerns:
What software should I use? Should I stick with Photoshop or use other software?
If I use PS, what are the proper requirements to be inputted in terms of dimensions and resolution that will not hinder my computer's high-performance? Specs: AMD A10, 16 GB Ram. Graphics: Radeon R7 12.
Someone told me that it is done panel by panel. What is the process to be done when the output is ready for printing (or is it the printing house's concern to panelized the output?)
