I use right now your T-SHIRT template, I uploaded an 1920x1200 picture, then ordered it.
In order viewer when I export it, the image quality is really bad. I cant print a T-shirt with this exported pdf/jpg.
I bought the plugin.
Attached the exported pdf.
We are aware of this and would like to sincerely apologize. The issue is caused by externally developed libraries. We are working hard on implementing our own web-service to solve the issue once and for all and to massively improve the export functionality in general. For the moment you'll need to use the image export and generate the pdf yourself if you need to print the product.
