Very large photo file size.

Hi,
Is there anyone who could advise me. I have been tasked to create a picture that is to be printed 7metres long by 1.5 metres high. This image will have a large band of text where I will insert all of the employees pictures inside the text. each letter should hold around 65 peoples head and shoulder photo inside. There will be ten letters in total giving me enough space for 600 people. I have taken most of the photos and they will be around 70mm square when printed to the final image size.
this is where the fun begins. I realised that the file size would be to large to create at 300ppi. when I created a blank file to put the text on at 72ppi it came in at 250mb without any images inserted in photoshop. I contacted the printers any he said it may work if I created the file at 10% of the final print size and he might be able to resize it to print. I then inserted a few hundred of the images into the text and cropped them to 10%of the 70mm which made the crop at 7mm X 7mm at 300ppi. the image seemed to be working well at 300ppi at 10%, but when zoomed in to close seemed to be pixilated. I visited the printer to see if I could get a sample section printed and as expected it looked awful.
Chatting with the printer we thought it would be better to use Illustrator. I cropped the images in PS to a square crop at 300ppi and saved in a separate folder. I then placed them into the Illustrator document created for a print finish at a third of the finish size and at 300ppi. This again has created a stupid file size which is now at an unusable 800mb.
I am stumped in what to do, if I made an initial file that is 72ppi, how can I place images in that are 300ppi to print when resized. I thought the images would only be linked to the file from the destination folder. Does anyone out there have any ideas on how to achieve an image that is usable and will print at the desired large dimensions that will be viewed close up by the employees.
Any advice would be greatly appreciated.
P.S the reason each picture has to be entered individually is so that we can update the poster annually with new staff.

Thanks,
Pat.

Have you thought about creating a series of files on a white background - each of the individual files containg an element of the whole - the printer then runs the final banner a number of times each time printing a different element of the picture ??

Hi David,
Not sure what you mean. Do you mean split the image into three separate files.

The largest we've ever done was a canvas 15 feet by 3 feet for a farm shop. This just fitted on a DVD when we dropped the resolution. It didn't need the ultimate dpi because it's hung above the meat counter with the lower edge about 8 feet above the floor.

How close will the viewers get? This will determine the resolution that you actually need.

If you really must have a 720 dpi, 16 bit TIFF, then put it onto an external HDD when you send it to the lab for printing.

when you say `unusable' at 800mb do you mean you aren't able to transfer the file to the printer?

if so, the have you looked at dropbox..their basic free service is 2Gb and you can upgrade to larger files. All you do is drag and drop..the client signs in and is able to do the same at their end.

apologies if I'm being simple! Smile

Hi cats 123
The reason it is unusable is that I still only have a fraction of the images inserted into the text and the file is 800mb plus and the mac is having major difficulties processing the file.

Do you have InDesign - I could probably figure you a work around but if would involve your printer more than yourself... do they have it?

I would imagine they do have Indesign. I have managed to get the file size down slightly and possibly could struggle through. What would you suggest if using Indesign.
