I have a very tight deadline to create a trade show booth poster in Adobe Illustrator. The size is 40" x 53.5". It is CMYK, 300 dpi.
One of the stock photos that I must use in it, which has been provided to me by the client (purchased on istock), needs to be scaled up in size (altho the resolution is thankfully ok, at 300 dpi). Basically the width and length of that photo is too small, and I have to scale it from about 5"x10" to about 12" x 26".
I am worried that this will print too pixelated. Does anyone know if it will look ok enough? I am unable to get in touch with the printer since it is for a large trade show through a client who can't figure out who the printer is. So I can't ask anyone any questions about it :(
It is for a kiosk so I think it will typically be viewed from 3 feet away. But even that I'm not able to find out.
To be honest, I don't see any photos on istock that would be the right substitute that would be large enough anyhow. Is there a database out there for poster sized stock?
