Hi =)
I have designed some posters which will be 120cm x 60. Its the first time I have done something this size for print. When I went to export these from Illustrator as a tif, I found I could not export at 300 dpi, as 'the size of the artwork combined with the resolution exceeds the maximum that can be rasterised".

Can I export these for print at a lower resolution? If so what res should they be?

Thanks very much in advance for any help.

Or just plain ol Illastrator .ai. with the image embedded.

What does your printer request? Did you call him to ask him what he can use?

Save in illustrator as a press ready PDF--the file's smaller and you still retain quality. Or, if a tiff is required by your printer, open file directly in Photoshop at 300dpi.

ttfn!

Target Resolution

Your resolution requirements depend on what printing process is being used.

Offset: 300ppi at 100%
Digital: 150ppi at 100%

When in doubt, ask the printer.

150dpi is actually a bit low for some digital printers nowadays. if you're printing to a nexpress or other high-end digital device, you're giving up some of that machine's capability in print quality at 150dpi. even some of the newer color copiers can give you a bit better quality with a higher resolution than that.

there's a pretty wide range of quality output on different large-format inkjets as well.

in the end, it's always best to ask the printer what the optimal resolution is for output on their devices. once you get to know the different pieces of equipment that your vendors use, you'll start to know more instinctively what works best, but it still never hurts to ask.

Thanks so much

for all the advice so quickly. I have spoken to the printer and he is OK with the 150 dpi tifs. It is really useful to know the different possiblities so thanks again to all for your help.
