TIFF file over 4GB - print project

@BryanPS 

A few notes on Jpeg:
Jpeg files have compression applied, changing resolution or cropping and re-saving enhances the compression artifacts - this means that Jpeg is only really suitable for final file delivery/transfer - with the Jpeg created only once size and resolution (and any sharpening) have been completed. 
 
So, Jpeg is far from ideal for editing and not OK for archiving or for any file that may need to be resaved, resized or cropped down the line.
 
Jpeg is the worst possible format if you want to keep high quality - you should always archive a copy of your original, ideally with any adjustment layers intact - if you work with layers.
Jpeg compression (at any setting*) really is "lossy”, irreversible, and cumulative, so Jpegs should ONLY be used only for final delivery and only created from the original file format AFTER resizing & cropping to the FINAL size and crop.
To explain: any edits to size or crop, or even just re-saving a Jpeg file means further compression, potentially that’s very damaging.
The JPEG compression damage is not always immediately apparent, which is perhaps why it's still widely used - however, that compression will soon cause issues if you do further work and save again. That’s when you’ll see a Jpeg with some real issues.
 
*don’t imagine that selecting maximum quality for your Jpeg is preserving the original data, it’s still compressing a lot which discards information.
SO, don’t reuse Jpegs if any resizing or resaving is needed. Always go back to the PSD/ Tiff originals, Jpegs are essentially a 'use once and trash' file type.

Hi, TheGraf

Whats your question please?
And why did you need to do that? What is the image use to be?

"app uses intelligent math algorithms to increase the overall quality of the image" 

it would HAVE to be intelligent as it's making up detail. 

I hope this helps

thanks

Hi guys, I have used PhotoZoom pro to increase dpi after I have saved it in Tiff format with smaller dpi and app uses intelligent math algorithms to increase the overall quality of the image

Just to get it out of the way: a file in excess of 4GB is enormous, much larger than anyone would normally ever need.

You don't need 300ppi for large format prints. The larger, the lower the ppi. In fact, a wall-sized banner needs about the same amount of pixels as a magazine spread. The pixels are just printed bigger.

So the point is - is this for some very special purpose, or are you just making a banner / billboard for normal viewing distance? If the latter this is overkill and wasted.

Hi,

JJMack is right if you select discard Layers under Layer Compression under the Layer Compression options that should decrease your file size considerably.

Tiff file format supports data compression and can save a flattened version without layers. Have you tried all the data compression options available to see if any will save under 4GB

Reduce to 8 Bit Color if 16 bit color to cut the size in half.  Also 8 Bit color can use Jpeg  compression however its a lossy compression your image will loose much quality below quality 10.

Most Printers only support 8bit color....

That’s a design limit of TIFF. Your file is extraordinarily large so ask the printing house. Don’t try to second guess them. They might want PSB or insist you make it smaller or something else.
