Hi Richard
Are you sending via email? The way I do it is to click on file (in Photoshop), go to ‘Save for web’ and choose the resolution. Don’t think I’ve lost any quality doing it this way.

Hi Richard.
A 6 metre file in Photoshop is HUGE and even 1.8 metres is very big. Photoshop is usually used to create or touch-up pictures that might be A2 size max and these are then enlarged.
For this job, I would suggest that you reduce the length to 450mm x height in proportion (h.i.p.) and make the resolution 300dpi. Then tell your printer that the outputted / printed size needs to be 1800mm long x h.i.p. or that the artwork is 25% of full size required.
The RIP on his printer will easily enlarge the image and will usually ‘interpolate’ the pixels on the final print to make the output look like a good quality 300dpi print.
In general, large artwork does not need to be full size and 25% scale is a large enough file to get good results. Ask your printer what file type he prefers to receive for printing. Some want .pdf and others .eps or even .jpg. They each have a pferefence and will usually get best results with one type.
Also to ensure good quality, you need to have the colour mode correct to suit his printer/rip. E.g. if his printer is an RGB type, you will need to ensure that the file you send is corrected to print in that format (or CMYK if this format)
Hope this helps
Cheers

Think you might find the PDF file format has a 5mtr page size limit.

You only have to have your final image size as 150 – 160 dpi at the final image size, you’ll never see any difference above that.
Save the file as a jpg with no compression.This is the method my local printer uses to send large format files to me and they are only about 19mb for a 2000mm X 800mm image, they print fine even with small text/detail etc.

Hi Richard,
If you use PDF format and 300dpi or 150 lpi you should be able to reduce the size for portability wihout loosing any definition. I do it all the time being in the printing buisness.cheers
