Vector File, What Does it Mean?
I will try to give an understandable but not very technical explanation about what does it mean to vectorize an image, when to do it and what it is for.
I'll start with the latter. What is the use of vectorizing an image? Simple, to be able to reproduce a cut vinyl image. To reproduce a print vinyl image, you do not need to vectorize the image. In this article you can read the difference between vinyl cut and vinyl print.
In a vectorized image the lines that form the design of the image are formed by vectors that are scalable, that is, the image can be expanded as much as you want without losing quality, which allows the same vectorized file to be used both for a business card or for a billboard.
