Why is my vector file pixelated after printing it on big glass surfaces?
If a file format specifies DPI, it is most probably not a vector file. DPI, dots per inch, indicates the amount of pixels over the width of an inch in the resulting file. This is inherently a pixel ...

600 divided by 150 is 4, ...
