This question already has an answer here:
I need to export final files with at max 128mb for print on fabric.
My initial canvas size is 16.383px x 10.000px (the 16383 is the max allowed by illustrator).
I've noticed that even working in 300dpi, when uploaded in jpg format, even if my canvas size is bigger that the final application, my dpi drops to 190.
That's why I'm making a huge canvas with 400dpi.
As my Illustrator says that the jpg is too large to be exported, I'm opening the .ai file in Photoshop and Save As jpg from there.
The jpg file is 17mb while a PNG file is 600mb.
What I can do to have the best quality? What I should do?
Thank you very much if someone can help me.
