What DPI should a large format artwork for print be done at?
I want to design a large banner for computer shop and banner will be viewed from a far distance. I will be using photoshop CS4.Sizes to be designed are 11 ft by 5 ft (132inch by 60 inch). My pc have Intel Core2duo processor with 2GB Ram.
What could be the ppi to use for this design without crashing down my pc. Will 72 ppi be okay?
Thanks in advance.
