Getting Illustrator files print ready


Setting up bleeds in Illustrator: (2 methods)


One method is to create a shape tool of a box. Select the shape tool and click anywhere on the document. This will bring up the size dialog box. Input your size settings there like I did on the above image.


Then what I do is duplicate that box on top of the existing box by selecting the box, hitting “S” on the keyboard for scale, put 100% on the scale percentage and hit COPY. This will copy the box on top of the existing box without changing the size.


Now what you want to do is right click on the box you just created, go to MAKE GUIDE. This will change the box from a shape to a guide. This is to permanently implement the size of the business card into the document.


The next step is to drag the upper left hand corner of the ruler and reset the measurement to the top left corner of your business card to 0. We are going to begin the process of adding guides for bleeds.


Manually I add 1/8th of an inch all the way around my box with guides. You can add 1/4th of an inch. This won’t really do much but its a method of playing it even safer. (1/8th of an inch is .125 in decimal count. 1/4 = .25) Now bleed your existing business card box all the way to the guides.



One quick note, after you’re done with your design process, you need to re-size the artboard along the bleed size. DO NOT re-size it along the original design size. So for a business card, your artboard should be 3.759 × 2.25 in. height. Re-sizing the artboard is done through the PAGE SETUP under file.

The best method of setting up bleeds is through the bleed settings in the program. The BEST approach for this is using Indesign CS3 or 4 to set the bleed settings. You want to design your elements in Illustrator, save it as an EPS or PDF and import it into Indesign. But since the release of CS4, setting up bleeds in Illustrator has gotten much much easier. On the screenshot above, the easiest way is to click the TEMPLATE button in the FILE > NEW dialog box. Most of the time templates are notorious for it being cheesy and lame to use. But we’re just using the size dimension here. Not existing designs. Steal the dimension and we’re up and running. Adobe created templates for certain projects and business card is one of the templates available to you under the “general” folder. If you’re not doing a business card, you can just set your page setup as the dimensions of your project.


In Illustrator CS4, you can set the bleed settings in the page setup dialog box. Now it will be a long while till printers actually use CS4 so this is a very advanced method that won’t be used in printers for a while. The problem that I see is the fact that most printers will still use CS3, if not CS2, and artboards end up being guides if you were to save a CS4 file as a legacy CS2 or CS3 format. This “might” confuse the printers as the design will sit outside of the artboard. 


This is a screenshot in Illustrator CS4. The bleed guide is shown in red. The way it handles bleeds in Illustrator CS4 works the way Indesign CS3 sets up bleeds. It is very useful as the printer doesn’t just print the objects in the artboard but in the bleeds as well.


This is a sample image of how business cards should be set up in CS4. I bled the design all the way to the bleed line. There is no reason to set up bleeds if your business cards don’t have any element of design that bleeds off the edge. But it might be a good practice to just make it a habit to set up bleeds if you have it or not.


When you print in CS4, it is important to check the option “Use document bleed settings”. It is also a good idea to set up crop marks for yourself and for the printer. (I like using the JAPANESE CROP MARK setting due to the fact that it shows the crop/trim mark and the bleed mark.)

Converting black and white images the right way in Photoshop:


Have a colored photo you converted as black and white in Photoshop you are importing to Illustrator? The best way to convert images to monochrome (black and white) is to use the Channel Mixer tool. Many designers use the DESATURATE option under IMAGE > ADJUST > DESATURATE. But the best way is to use the channel mixer tool under IMAGE > ADJUST > CHANNEL MIXER. Make sure you hit the MONOCHROME check box like you see above. The difference is set below. RIGHT is the CHANNEL MIXER B&W. The LEFT is DASATURATED B&W.


If you can’t tell the difference, just pay attention to the girl’s body. You can see a distinct line separating the two desaturation method.

Deleting unused colors in Illustrator:


Using the example above, delete all unused colors after the project is done. This is avoid confusion or accidental color selection by you or the printer at the final process. Although if they screw up that way, they will correct it right away.

Using rich black and not 100% black:

Rich black


100% black (wrong way)

tut_2009-02-01_01-43-43; background-color: rgb(250, 250, 250); background-repeat: repeat-x;">In print, when there is a large type or element that uses a lot of black, it is a good practice to use rich black instead of the 100% black you usually use in your design programs. I can tell you right now that yes there is a difference when you print it out. Rich black is achieved by mixing all CMYK colors in different percentages. 100% black is when CMY is all set to 0 but the black is 100%. This is not a good way to achieve the best black. In paragraphs, it is better to use 100% black instead of rich black, so it really depends on your project. It is a good habit to always set your blacks to rich blacks in logo designs and headlines.

Setting photo’s as CMYK:


This is actually a frequently made mistake. ALWAYS set any photo’s you are using in print as CMYK (in Photoshop of course) before using it.

Using PLACE command in Illustrator:


When you place images in Illustrator for a poster for example, we design certain elements in Photoshop or have photo’s in posters. It is very important that you PLACE your images using the FILE > PLACE command and not cut and paste. The problem is that Illustrator lets you cut and paste (i think still) from Photoshop to Illustrator. You can even open JPG’s in Illustrator and design over it. This causes the file size of the Illustrator document to be BIG, and sometimes printers will take a long time printing because of the pixel data and the vector data. Placing images is like placing images in Indesign if you’ve used it. Basically it is placing the image by reading data from the different file source. It is IMPORTANT that you supply the photo or any raster images you used to the printer. Set up a file system like this:

Project folder
Main Illustrator .AI file

Burn these files to disc with that exact hierarchy and supply it to the printer.

Always set up documents as 300ppi for print.


Many people say “DPI” instead of “PPI” for the FILE itself. For example people state “print images should be 300DPI”. This is wrong. In Photoshop, there is no such a thing as “DPI”. DPI is strictly for the PRINTER HARDWARE itself and not the digital file. In digital file such as a photo, we use the term PPI (Pixels Per Inch). Even in the Photoshop resolution settings it is stated as “pixels/inch”. DPI stands for “Dots Per Inch”. During a print process, make sure your document is set to 300ppi before you start any print project. You will cry later when you have to convert a already finished project to 300ppi from a lower ppi resolution such as 72 (monitor resolution).
