Letter Size – Letters can be no smaller than .25″ or they will not embroider well.
Detail – Super fine detail will likely be compromised. Most embroidered logos are small by nature, thread is a fixed width and the fabric adds an element of compromise.
Gradients – Complicated gradients can sew very well. Keep in mind, however, that stitches do not blend, so the gradient will be less smooth in appearance than what you see on your computer screen.
PREFERRED FORMAT
Vector files (ai, eps, pdf) with fonts converted to outlines. This format produces the highest quality embroidery.
ACCEPTABLE FORMAT
Raster files (jpg, tif, gif, png, eps) at a minimum of 150dpi at the final image size.
These images, designs, or logos are composed of pixels rather than paths. When zoomed in it is more difficult to see detail and where shapes begin and end. For this reason a digitizer must do some creative estimating. Your end embroidery may not be as exact as you would like it to be.
