The
difference between Raster & Vector Graphics:
Raster
Graphics (such as photographs), also known as bitmap images,
are made of pixels. They have a fixed resolution and cannot be resized
larger without losing quality. Common bitmap file formats end in:
.gif .jpg .png .tiff & .bmp.
Vector
Graphics are images that have been created in a drawing
program such as Adobe Illustrator or CorelDraw. They use paths to
create lines and curves at connecting points called "nodes"
to store the graphic's information mathematically. Vector art is
resolution independent; whether you enlarge or shrink the image,
the output quality is never compromised. This is why logos
should always be created in vector art format.
Vector
graphics are necessary to cut vinyl lettering.
Common vector art file formats for include: .ai, .cdr, .eps, .svg
& .pdf.
Understanding raster graphics v.s. vector graphics is important
in choosing which design program to use for a particular project.
Logos should always be created in vector art formatso your logo
will be scalable without losing quality.
If your logo was never a vector, or if the original art file has
been lost, the only alternative is to have a professional
graphic artist recreate the logo from scratch in a vector
art drawing program.
