Corel has a 30,000 pixel x 30,000 pixel limit.
Double check your Photoshop image as 1,000 inches at 300 DPI exceeds the tif limit.
i am able to save12inch x 1000inch @300dpi tif file in photoshop with LZW compression.
Photoshop supports 300,000 x 300,000 pixels however not in the PSD file format. The PSD format only supports 30,000 x 30,000 pixels which is the same for CorelDRAW and Corel Photo-PAINT. The TIF file format supports up to 4 GB of data, PSD supports up to 2 GB of data.
This process will require true 64 bit RIP print systems.
In 32 years I've run into this twice and used PhotoZoom to upsample my image and verified the final TIF file resolution and physical dimensions in GIMP as Photoshop had an error at near maximum size. Photoshop showed the proper physical dimensions but automatically reduced resolution.
Your print will be 83.333 feet long and therefore will be 83.333% of a roll of most media as most media are in 100 foot rolls. An extremely costly error to reprint.
