Very large jpeg file to pdf problems

Hi, I'm trying to convert some very large (150cm*260cm @ 300DPI) jpg files to PDF to send to my commercial printer. I've tried using PrimoPDF but it just hangs/crashes. I've tried using Save as PDF in photoshop but the pdf that is produced is a similar (if not higher) file size eg 194MB then the original jpg (193MB).

1. Shouldn't I be able to reduce the file size significantly when I convert to PDF? The current size is too big for the commercial printer's printer.
2. Should I use a particular program/method to convert files of this size?

I will be using WeTransfer to send the files once I can get them into 150cm*260cm PDFs of an appropriate size.

I'm not a graphic designer and am a self taught photoshop user so any help would be appreciated.
I am having the image digitally printed so need to retain quality.

Thank you.

Why is the file size an issue?

I see our shop make 1GB files all the time for print jobs.

No. JPEG is already compressed, PDF has to hold all that and a bit more so my experience at the same quality PDF is bigger.

The days of small files seem to be over here.

Can you put one up on a Public Dropbox for me to try it on one of our highend workstations?

Huge file size PDFs

Hi R.Proffitt. Thanks for replying. I'm not exactly sure why the file size is a problem. My printer says that the jpeg files are too big for his printer. I'm certain it's something about my files as he doesn't have this problem with his other clients. It is for textile printing.

I created the jpegs from extra large high res images I purchased (incl. appropriate licenses). Flattened them and then saved them as jpegs. The photoship files are .psb because they are so large (3,122,611KB). I can't even PDF them at all (the ones I thought I had done were not to the correct scale). PrimoPDF or Adobe Acrobat simply can't do it.

Should I be doing some sort of changes on my .psb files to reduce the size and then remake the jpegs and then try the pdf conversion?

Thank you for replying!

Maybe

Since I don't have a JPG or PDF to check out I have to let you do all the work.

1. What size is the print area?
2. What DPI is it printed at?

Some folk overdo the initial dimensions.

Print area size and DPI

Hi there, I've ended up just giving a reduced dimensions and DPI file to my printer for them to do the conversions.

I'm obviously doing something wrong in my artwork set up though. The canvas dimensions are 150cm x 260cm. This is the same size as the end product. The DPI was set at 300.

I figured that I hadn't cropped my images and that when I did it reduced the .psb and .jpg files by half. I still couldn't convert them to pdfs though due to their size.

That's one exit.

Another may have been to let another person try other tools to give it a go. Dropbox is one of the many tools I use for such trials, just for the transfer of fairly big files.

I can't list all my exits here but last month Inkscape saved the day as I loaded up a file and saved as PDF. Another time it was DoPDF. I'm sure there are more tools than I can remember.

Anyhow, hope it's done and done.
