There's is something very wrong if a system with that spec is not doing the business for you. Can you tell us some more about the prints you want to make? Where and how they will be viewed sort of thing? I was going to place This Video in the thread, but Jeff Schewe is the best person I know of for large prints, and he has an excellent article HERE.
I was also going to suggest Luminous Landscape. I am not sure of the situation with LL since Michael Reichmann so sadly died. There appears to be a $12 per annum subscription charge for full access now.
OK, so rather than focus on the print, can you tell us about the content? Is this had drawn artwork? The only parallel I can think of in that respect are Bert Monroy's Gigipixel illustrations, but they are mainly intended for online viewing. He still had to produce the artwork, but it consists of dozens of separate PSD files which I presume are flattened when combined into the master document.
What I am angling at here, is how much can be produced as vector art? IME Even when mixing raster and vector content, the always sharp at any size vector content helps give the impression of overall sharpness even with some lower res raster content. Exporting such a document to PDF ready for print would give you something that would print at _any_ size including road side billboard.
Do you have Illustrator? Without knowing what your artwork consists off we can only guess, but it might be that Illustrator is a better option for you. I sometimes use the Freehand Pen tool in Photoshop because — if you are on a Windows system — you can use that tool with Lazy Nezumi Pro and produce beautifully smooth, fully scaleable lines.
The bottom line here is I _really_ don't think you need 33Gb image files.
Trevor, again, thanks for your response. I visited the Puget Systems website to look at some of their Photoshop workstations (https://www.pugetsystems.com/recommended/Recommended-Systems-for-Adobe-Photoshop-139). I noted the following: “With up to 64GB of RAM (system memory), this system is ideal for anyone working with images that are up to approximately 3GB in size. If you work with even larger images, please contact one of our sales consultants for a custom configuration.” So, obviously, in their view, a 3GB file is extremely large. It follows, at 33GB file would be crazy.
I’m also finding that there are extreme differences in some of my file sizes. I need to take some of these extremely large files and deconstruct them. For example, I can take that 33GB file and copy it, layer by layer, into a new file, monitoring the size of that new file to see if there is any sudden inflation.
For me, there are two key questions: Are some of my files much larger than they need to be? You suggest “Yes,” and I think you are right? The other question is: Should my system be able to handle a 33GB file. From what I can see (e.g., here (https://www.pugetsystems.com/recommended/Recommended-Systems-for-Adobe-Photoshop-139 and here http://www.auspcmarket.com.au/image-science-x99-extreme-image-editing-system-ddr4-6-8-core s/, the answer is “No.”
Thanks, again, for your help.
