What is an embroidery file, Vector or Raster File?

Embroidery Files:

Embroidery files are only used to drive embroidery machines; they give machines the coordinates and sequence of each stitch in a design and prompt when to change colors. Common file types are .DST and .EXP.

Vector Files:

Vector files are made of lines, points, and curves that can be resized without loss of image quality and are easily altered. Common software packages that create vectors are Adobe Illustrator and CorelDRAW and common file types are .AI, .CDR, and .EPS.

Raster Files:

Raster files are made of pixels, or individual dots of color, and can’t be altered very easily. These files lose quality when upscaled, so they must look clean and crisp at the physical size of your finished print. The most common software used to create raster files is Adobe Photoshop and common file types are .PSD. BMP, .TIFF, .JPG, .PNG and .GIF, but the latter three types found on the internet lose color and clarity to save bandwidth and thus are rarely of high enough quality.
