I designed a banner in IllustratorCS and saved it as an illustrator file. The printer likes a raster file so I then opened it in PhotoshopCS. Initially, I could not open the document at 800cm and 72dpi. So i chose 400cm and double the resolution to 144dpi. Strange, I thought, since it turns out to be the same number of pixels. So i finished the banners.
Now I have designed another group of banners in Illustrator of the exact same size. When I go to Illustrator it tells me I can’t open a file larger than 290 cm. I fooled around with it for a long time since I knew i’d just opened one at 400cm. Ok, so again I don’t have much time left so I go to 288dpi and open it at 200cm. Same exact pixels. Strange.
I go back to the original AI files (the first group of banners). Again, same error messages. The same files i’d opened before!
Why was there a change in the limitation? Why is there a limitation that depends on print size rather than the total number of pixels? Does anyone have any answers or maybe some kind of size limitation guide or rule book i should be looking at? This one part of photoshop was always very confusing for me. Thanks for any help.
