Failed to export to PDF for a large poster

[F_Rivera]

I cannot seem to save 2 large projects to PDF

These are my steps for exporting:

1. file

2. adobe presets : PDF X-4 or hi quality print

3. include bleed

4. attempt to save

5. rejection

I have recreated the file from scratch

I have moved the file to a new file

I have asked a different person to save the file > no luck

I had our IT guy try to "downsample"... it only worked when we scaled it half way and then weird stuff happened

Since my deadline has come and gone, I was able to send something I hope is accepted. What I ended up doing was sending a file with a PPI of 297 or as close to 300 as I could get. This has allowed me to save the PDF, what I'm trying to do now is learn a better process while achieving great results.

Yes Bob, as I suggested in my post to the OP 4 March. The OP doesn't seem to want to accept advice!

[F_Rivera]

Derek,

I have not rejected your advice, I have stated my issues even after submitting a lower resolution image. The result of which was poor quality.

What I would love to learn from either you or Bob is how to achieve the results you and Bob have had before. I have not seen that advice yet. I have followed everything either of you suggested and I'm not trying to be difficult.

[Derek Cross]

The quality of the reproduction of the image depends on the quality of the original, if it's too low resolution increasing the size won't improve it and make it sharp.

[F_Rivera]

I agree Derek,

Please correct me if I'm wrong but I am downloading hi-res images.

This is where I'm am downloading it from 2018 Nissan Armada Photos Nissan Online Newsroom

Once I download, I noticed I had to scale the image significantly and that is why I increased the resolution.

Please let me know if you see any red flags about this approach.

Again, you cannot increase resolution. It’s simply impossible.

While PS may do a much better job of enlarging than it used to, there’s still a limit to what can be done.

[F_Rivera]

Thanks Bob, I was only following alternatives that I had read about here Photoshop image size and resolution I know there are limits to what it will look like and in the end, I hope my most recent submission will be accepted by the vendors.

Thank you both for your help it seems like there isn't much of a solution other than submitting a lower res image and hoping the quality is good enough to be displayed.

[F_Rivera]

Other solution learned through this was to request a larger image so that i dont need to process in photoshop

If you select an image in ID or in the links panel, like the front-end image above, what is its effective resolution?

I've done a fair amount of large format work and I have rarely used an effective resolution greater than 150 dpi when sized in the document. There are exceptions, but like I wrote, it's pretty rare.

Just about all of it, unfortunately.

You cannot just create a 300ppi image by typing in a number. All you're doing is create a huge file for no reason at all.

Again, posters do not get printed at 300 ppi. Generally, 50ppi is plenty.
