Illustrator won't save large RGB file 8000 by 12000 px min 300dpi

[kellyk79174284]

I need help saving a large file for printing. The specs are 15000px x 9000px, a vertical asset that’s 8000px x 12000 px, and a square asset that’s 12000px x 12000px, at 300 dpi at RGB. Every time I try I get an error message " The operation canot complete beacues of an uknown error . [!now]. Does anyone know of a solution? The dropship company needs images in png and jpg formats only.

Since you have a PPI specification, you need to be thinking about your files with physical dimensions, not pixels.

15000 x 9000 px at 300 PPI is 50 x 30 inches, for instance. You should find that if you create a 50 x 30 inch file and export at 300 PPI, it will match your specifications.

And what specifications do you need to match?

Those pixel dimensions and then 300 ppi?

online dropshipping companies seem to have different specs to a normal printing business. They want their files in RGB and only png or jpeg format only.  Everytime I try to export png files in illustrator it comes up with an option box high, med or low resolution but it won't allow the selection of high resolution at these large px ratios, I  receive the !now error.  

Just for your reference the Society6 website states " we recommend starting with a horizontal asset that’s 15000px x 9000px, a vertical asset that’s 8000px x 12000 px, and a square asset that’s 12000px x 12000px, at 300 dpi. ".  I have (since my first posting) noticed that each product on their site , has different product specs and am yet to find a product that needs these extreme dpi to pixel ratios ( Unfortunately, to see each product spec you have to become a member and try to upload a file ) I think on their how upload an artwork file page is a recommendation overkill.

The thing is: those companies don't know how resolution works.

If they give you pixel dimensions, then there's no need to have resolution as well. And in the case of Illustrator, this is always derailing inexperienced users. If you want to keep pixel dimensions in the output, then in Illustrator, don't export at 300 ppi.

In Illustrator in order to keep the pixel dimensions, export at 72 ppi.
