CorelDraw exporting large files problem

[Jean Shimp]

I created a 6' x 90' banner in CorelDraw at 150 dpi full size. When I tried to export it as a jpg it automatically reduced the size of the banner to around 8' wide with a maximum resolution of 300. I imported that file in a new window and scaled it up to 90'. Needless to say it looked awful with a dpi less than 50. Second attempt - tried scaling the image down to 8' wide before exporting, the resolution automatically changes to over 1500 dpi on the desktop. Tried to export as jpg, but I could not increase the resolution higher than 300. That attempt looked worse than the first one. Any suggestions on how to resolve this? Thanks.

What is actual viewer's distance of the banner so wide?

The value of 150 dpi (ppi) is likely much too much and why the need to export the file as a jpg?

My print vendor requires either a jpg or pdf file. I don't print "in house".

This will be viewed fairly close up as it hangs on a construction site fence by a sidewalk.

So export it as a pdf.

JPEG has a file size limit of 65,535×65,535 pixels. 90' x 150ppi is 162000 pixels. I'd just do a PDF.

Always, always print from pdf's, this is what they are intended for! Publish as CMYK of course then select the Object tab and in the bitmap compression area use jpg for the type of compression and around 10 to 50 for quality , I normally use 2 but for large files this is not needed and 100dpi for the bottom three choices, you can go as low as 25dpi for billboards.

Use the pdf

What kind of content is in this CorelDRAW layout? Does it have a bunch of embedded photographs or any other pixel-based stuff? Or is all the content vector-based? Either way PDF will be a better choice than JPEG. Any vector-based objects (such as type elements) can be maintained as vector-based objects. The overall exported file size could end up being smaller.
