Sorry if it's too basic, I have some work that where made in Illustrator using the line tool, so it's made of lines with a stroke of 3pt .
Then, I have to print it on large size (vinyl decal) , and I am trying to make sure the line would appear the way I want it .
When I scale my work (by cmd+drag) the lines appears smaller and the work looks bad.
How can I get the result according to what I see in illustrator ? (So the relation between lines distance and their width will look as it looks on my screen)
