what does bleed contained by printing?

A "Bleed" is where on earth color goes adjectives the way to the perimeter of the paper. It could be a perspective color, background for a essay box or whatever....
I deliberate it means a 3 millimeter border.



Bleed unanimously means when your ink runs.



(P.S. Please don't copy my answer and re-answer duplicate question beside the exact same information, to people below me :D)
If the print go to the very margin of the paper... no fringe!
the "bleed" refers to how close to the edge you have need of to go. close to if you want to print with color adjectives the way to the slither of the paper, most printers wont do that so you hold to print your page and then cut it, but say-so you want to print 1,000 of them and you dont want to to sit there and cut them beside scissors so you take it to kinkos and own them cut the 1,000 with a huge mechanism, that machine is not exact and some are going to bring back cut a little rotten center so if you dont have extra color going stale larger than what you want kinkos to cut down to, then you will own a cockeyed white border showing very clearly that it wasnt cut exactly.



hope this help...
If an image is designed to be in motion to the edge of the rag after it is trimmed such as a full picture on an 8.5 x 11 inch page, then the portrait should actually progress over the expected trim line. The depiction you need to donate them should be 8.75 x 11.25. That way if their trimming blade is a little bad, you won't have an unwanted white dash along the edge.
bleed :is a printing residence that refers to a design that has ink printed adjectives the way to the farthest point of the finished page
