Topic: File Preparation
Why did we develop this complete guide to the preparation of files to print with bleed?
Having worked with thousands of business owners and their creative teams, we know that this topic is important. Bleed is one of the topics that more headaches create for anyone producing artwork for print. As opposed to artwork for web, files for print output require some additional considerations. In this article, we will focus on the preparation of bleed. This is a guide that is as complete as possible. Different software tools operate differently so you might still need to research specific actions for each design tool.
In a previous article, we explained what is bleed. Please check that article that is part of the Technical Knowlege section within the Printing Academy index. Here is a link to that article "What is Full Bleed in Printing"?
A quick overview of what is required to have a printed piece that bleeds
To reintroduce the concept of bleed and understand what is required in a file, we will start with an example.
The image displayed below shows a sheet (there is a white background to it) on top of which, a picture of a landscape is printed. The trim/crop/cut (all three names are equivalent in this application) marks are shown as well.
The final size of this printed sheet is set to be as follows: 8.5" wide x 11" tall.
It is clear from this image, that the piece has to be printed in a sheet that is larger than the 8.5"x11", only to be trimmed. In this case, the size of the sheet is at least 9"x12" so that there is enough space to print the trim marks. The printed piece itself is in this case 8.75"x11.25".
On the picture, you see that the printed picture extends beyond the trim marks.
Why does the image go beyond the expected trimmed size? Because if it was not set like this, once the paper is trimmed, a thread of white paper might still be visible. As every other manufacturing process, there are variabilities that we have to account for.
Setting up the Microsoft Word and Adobe Illustrator to create a file with bleed.
How to fill in the dialog boxes in different platforms. What to input?
Many graphic artists will use Adobe tools such as Photoshop and Illustrator. A good number of other creatives will use other tools such as Microsoft Word, that don't require a steep learning curve. We will show a couple of examples in a couple of software design platforms how to set those files so that you can create a file with bleed and trim marks.
Step #1 - How to determine the full size of the image to be printed
Our experience tells us that if the area beyond final size of the piece is 0.125" (in fractional notation, it is 1/8") on each side,that is enough extra-printing to prevent white from showing-up
The suggested Width for your artwork is calculated as follows:
Add 2 times 1/8" to the final size of your piece.
For this example: 8.5"+2x1/8"
which is the same as 8.5"+2x0.125" which equals 8.75"
The suggested Height: Calculates in the same way, 11" + 2*1/8" which is the same as the decimal notation, 11"+2*0.125". This is equal to 11.25"
Tip: Never do this to solve the lack of bleed in your artwork:
What's the biggest error some designers do?: Stretch the image to artificially create bleed. This is a mistake because stretching the image will result in part of the image being in the bleed area that will eventually be trimmed. Trimming removes part of the image so it results in a final piece that is different to what was expected.
Often times the copy gets to bee too close to the edges or can even lose an important portion of the document
Step #2 - How to set up these values in the graphic design software?
We will show the process for the following two design platforms:
A - Adobe Illustrator / B - Microsoft Word
AI - Illustrator: Create a New Document in Illustrator.
AI Adobe Illustrator: This is what the artboard should look like.
As the versions of this popular software evolved, so did the menu organization. Therefore some options might be in a different place in your version of the software. In this case, we are referring to the 2020 version of Office 365.
- The following screenshots and captions should help you to create your document.
Step #1 - Create a New Word Document -
Step #2 - In "Layout" menu, choose Size
Step #3 - in Page Setup, choose CUSTOM SIZE
Step #4 - Assign the Width and Height and press OK
- Step #5 - Under the "Layout" menu select "Margins" and "Custom Margins"
- Step #6 - Set the margins as indicated and press OK
- Step #7 - Word might think that your are making a mistake, but it's OK. Just IGNORE
- Step #8 - This is what your artboard should look
- Step #9 - The yellow square will contain the artwork that will be delivered to you.
- Step #10 - Export as a PDF: This is what you should get
Creating files that should print with bleed requires some care
Most clients are challenged by the preparation needs and decide to create documents with a white border instead. In doing so, they are probably losing some potential in terms of the quality of engagement that the piece could create
