Bleed
Bleed is extra artwork extended past the trim or print edge so ordinary cutting or garment tolerance doesn't leave an unprinted white sliver at the border.
Bleed is the margin of artwork built out beyond the actual trim line or seam, usually 1/8 to 1/4 inch on a gang sheet or all-over print, so that ordinary cutting and garment-construction tolerance still lands on printed art instead of on bare fabric. Cut-and-sew blanks and sublimation panels don't cut with the precision of a paper trimmer — seams shift, panels can run an eighth of an inch off from one garment to the next — and bleed is the buffer that absorbs that variance.
This matters most on jobs where art has to run edge-to-edge: all-over sublimation prints, DTF gang sheets covering a hem-to-hem panel, and printed neck labels or tags where the art meets a folded or sewn edge. We've had reorders come back with a thin white line down one side of an all-over hoodie print because the original file was built with zero bleed and the fabric panel shifted a sixteenth of an inch on the cutting table.
The rule pros use: extend background colors, patterns, and edge-reaching elements 1/8 inch past every edge that will be cut or sewn, while keeping any text or logo well inside the safe area on the opposite end. Sublimation and all-over-print shops usually specify their own bleed requirement right on the template — build to their number, not a generic default.
Buyers commonly assume bleed means the whole design has to run edge to edge; it doesn't. Bleed is just the small overflow margin added for cutting tolerance — a garment with a normal, bordered print doesn't need it at all, only jobs where the art is meant to reach the trimmed or sewn edge.
