What is bleed exactly?

Bleed. Look at a Modern Picture that bleeds!: When you get your pictures developed at a Kodak Store (or Walgreens or CVS for the matter), your pictures will usually take all of the photo's paper. You'll get something that looks like this printed picture with bleed shown here:

How to prepare a file so that it prints with bleed?

Let's look at how modern documents are created. We'll look now at commercial printing. Color printing allows to reproduce the same scenarios that were described for family pictures.

What should I do then?

There is no "commercial or industrial" way of printing a piece of paper right to its edge without taking the risk of having a thin undesired white border, or without making the back of the printed side dirty (offsetting).

Here's what needs to be done:

The way in which a piece with bleed is produced requires the following situations to take place:

  • The printing company needs to print in excess of what the final piece's size is required. The excess is usually 1/8" in US and about 3 to 5 mm. where the Metric System is used.
  • Once printed with the excess explained, that excess must be removed to bring the piece to the actual required size, a process known as trimming.

FILE PREPARATION and PRINTING COST

We will take as an example, a printed piece that once trimmed, will have an overall size of 8.5" wide x 11" tall. In your layout software set for an image size of 8.75"x11.25". The next paragraph explaines how we came up with that number.

Width: You should add 1/8" to each side of your piece, so the width should be set to: 8.5"+2x1/8" which is the same as 8.5"+2x0.125" which equals 8.75"
Height: the same concept applies, so if the height of the document is to be 11", then the image in the file should be 11.25".

PRINTING COST: What does this bleed requirement mean in terms of the cost of printing with bleed:
• The paper size needed is bigger than 8.5"x11". Printing on a larger piece of paper becomes more expensive
• The paper needs to be trimmed. Trimming is a process that requires additional equipment and labor, therefore increasing the production costs.

A BIG ALERT NOTE: Keep in mind that the portion of the image that is printed outside of what is going to be the final size of the piece will be trimmed and removed. So the part of the image that goes into the bleed area should be the extra image that will go once trimmed.

What's the biggest error some designers do? Some people just expand the image that they want on their final piece. This is a mistake because expanding the image will result in trimming. Trimming removes part of the image so it results in a final piece that is different to what was expected.

Rule #1 for Bleed: Create bleed with "additional image", not by expanding your image

3 reasons to have your document bleed

Bleed allows for a more focused view

Bleed allows for more attractive visual impact. Please observe the effect of bleed/no-bleed on a simulated book cover.

book no bleed - it is unusual to have books with images that do not reach the edge

Documents that bleed are usually viewed as being "more professional". That means more efficient marketing actions. Amateur documents, on the other hand, designed through home-desktop-publishing software usually have thick white borders

Borderless pictures are called pictures that "bleed". Because there's no white frame, in order to get it done properly, you must get the photograph printed on a slightly large paper and trimmed. In that way, you make sure that no white edge will be present.

The same concept is utilized in printing. Either in the case that you're printing brochures, of printing color copies, or door hangers, or business cards, every time you want your images to bleed, the printing house will need to use oversized paper that will later be trimmed to size:

Oversized papers are more expensive than the standard papers just described because a) there's more paper and b) once printed, there's a need to further process the printed piece.

Let me explain: If you're color printing on an 8 1/2" x 11" page without bleed, you take the paper in the final size, print it with the proper equipment, and you're done.

But if what you want is an 8 1/2" x 11" piece that bleeds, then you need at least a sheet of paper that's 9" x 12" (I'm sure that you already realize that the additional paper around what you actually expect to get is a "long piece" of about 1/2"inch with by 42" long (perimeter). That extra paper in turn needs to be cut down to size. To cut paper with precision you require an expensive cutter, with sharp blades and skilled operators to get things done.

As you can see, printing a color copy bleed project requires some knowledge but is not that easy to do. Let us know if we can help.
