Appendix . Output: Sending Your Files to Print

Getting It Printed

Creating artwork on your computer is really only half the process. It’s not like you’ll be inviting everyone to your home or office to see what you’ve created on your screen—a client might not be too keen on that. Rather, after your design is complete and approved, you’ll need to send it to a printer to create the final piece.

Naturally, each job is different. In some cases, your final product will be a website or a PDF, but most jobs require a printed piece as the final product. This chapter specifically covers jobs that are printed by an offset printer.

The Love-Hate Relationship Between Designers and Printers

Ask some printers what they think of graphic designers, and they might answer, “They are the root of all evil.” Other printers get along with designers just fine, so what’s all the fuss about? In reality, the issue stems from designers who aren’t familiar with the printing process, its capabilities, or its limitations.

The biggest complaint from printers is that designers create art that is very difficult to print—and in many cases, they design art that can’t be printed reliably at all.

As a designer, you have only to gain by learning more about the printing process and applying that knowledge to the art you design. For example, don’t create 5-point white text that knocks out of a process color background. Find out how close you can come to the edge of a page (a printer needs “gripper” space), or if you are creating art that will come to the edge of the page, be sure to add a bleed (extending the art past the edge of the page).

Undoubtedly, there’s a gray line between what a designer is responsible for and what a printer is responsible for. But when it comes to getting a job done and there’s money on the line—and a client waiting to get the product—you want to make sure that the job is done correctly. And the better shape a file is in when you hand it off to a printer, the happier everyone will be in the end.

I know that many printers value a designer who knows what they are doing, and will even refer design work to them when their clients ask whether they know any good designers. Turns out, I’ve gotten more than just design jobs referred to me over the years—my father-in-law is a printer....

Understanding the Printing Process

When trying to understand graphics, printing, and the technology that makes it all possible, I like to make a comparison to how some of the greatest professional athletes look at the sports they play.

Sandy Koufax is considered one of the greatest left-handed pitchers of all time, and what made him unique is that he understood the underlying physics of what makes a baseball curve, rise, or sink. He likened the human body to a catapult and understood the dynamics of throwing a baseball.

Tiger Woods is arguably the greatest golf player in history—and for good reason. Besides having talent, Tiger studies the physics of the game and understands why a certain club gives more lift than others, or how the direction the grass grows affects a particular shot.

The point I’m trying to make is that the more you know about your field, the better you can be at it, no matter what you do. In graphic design specifically, knowing about printing makes you a better designer.

Many of today’s printers are utilizing digital workflows to save costs and improve quality and turnaround time. Some printers have a CTP (computer-to-plate) system, which eliminates the need to create film, basically creating plates directly from a computer file. Although these methods present other challenges to printers (trapping, imposition, and so on), use of such a method also puts the responsibility on the designer to create art files that are free of problems (okay, so at least with as few problems as possible).

Understanding Transparency

The transparency features in Illustrator and InDesign have gotten a bad rap since they were initially introduced—and rightfully so. The technology was too new for the older systems that most printers were using, and, above all, there was very little information on how it worked, leaving many printers and designers to struggle with the settings. Most people didn’t even know that transparency existed, and printers who suggested that users save their files as older Illustrator files ended up causing even more issues. At the end of the day, it was all quite messy.

But transparency has come quite a way since then. Illustrator, InDesign, and Acrobat now all share the same flattening technology (necessary to process files with transparency), and, more important, the transparency features and settings across all of these applications are identical. Adobe has also been extremely proactive in helping print service providers and printers learn about transparency, and numerous guides and whitepapers are also available (I reference these later).

A Designer’s Checklist

Although it’s impossible to list everything that might go wrong in a job, several issues come up more often. As a checklist for yourself when you’re creating files or preparing them to send to a printer, here are some common issues to be aware of:

  • Make sure that everything is CMYK—Make sure that you haven’t accidentally created artwork in RGB mode. Many times you might use stock photography that you’ve downloaded from a website—and those images are almost always in RGB. Remember that almost all images from a digital camera are RGB and must be converted to CMYK in Photoshop before they can be sent to the printer.

  • Remember your fonts—When you send your files to your printer, make sure that you’ve included copies of all the fonts you’ve used in the file. Additionally, try to avoid using off-brand fonts that you’ve found somewhere on the Internet, or fonts from those “10,000 fonts for $9.99” collections because they usually end up causing problems.

  • Use spot and process colors correctly—If you’re printing a job as a four-color process (CMYK), don’t provide your printer with a file made up of spot colors. Likewise, if you’re printing a spot-color job, don’t provide your printer with a file that uses process colors. Some jobs combine both spot and process colors as well. If you aren’t sure, talk to your printer.

  • Make sure that images are high resolution—Sometimes designers use low-resolution images in their design but forget to replace them with high-resolution versions of the images before they send their files to the printer. Sometimes designers copy files from a website, and those images are almost always 72dpi low-resolution images. Make sure that photos taken with a digital camera are also of sufficient resolution.

  • Check Illustrator resolution settings—If you’ve applied any effects in Illustrator (they appear in the Effects menu), those effects might need to be rasterized at print time. Drop shadows, feathers, Gaussian blurs, and some mapped 3D artwork are examples of effects that get rasterized at print time. To ensure best results, make sure that the Document Raster Effects Setting is set to 300dpi.

  • Check Transparency Flattener settings—In many cases, if you’ve used native Illustrator CS and InDesign CS files—and PDF 1.4 files or higher—your printer will determine the correct flattener settings. But at times you might be working with EPS files, or your printer might ask you to export older format files. In those cases, you’ll be supplying files to your printer that are already flattened. Flattened files can’t be changed, so if they aren’t correct, the printer can’t fix them.

  • Check your stroke weights—Just because Illustrator and InDesign allow you to specify extremely thin lines, that doesn’t mean a printing press will be able to reproduce them. In general, never specify a stroke weight that’s less than 0.25 point. Pay attention to logos or other art that is scaled: A logo that has a 1-point stroke that is scaled down to 20% in your InDesign layout will end up with a 0.2-point stroke.

  • Check your tints—Specify tints that won’t cause problems on press. Tints lower than 5% or higher than 95% are usually problematic. The truth is, each printing press is different, and printers know what their presses can handle; it’s best to ask your printer for suggestions.

  • Add bleed or gripper space—If your design includes art or a background that is supposed to print all the way to the edge of a page, you have to specify a bleed, which is basically extending the art outside the boundaries of the page. This ensures that no whitespace will show when the page is trimmed to the correct size. Where art doesn’t come all the way to the edge of the page, you have to leave a certain amount of space, called gripper space, along the edges of your page (you can use margin settings to help you stay out of these areas).

  • Perform general file cleanup—Throughout the design process, you might choose from many colors, fonts, symbols, and so forth. When your job is complete, it’s best to “clean up” your file by deleting unused swatches, brushes, or symbols. Use the Find Font feature in InDesign or Illustrator to make sure that you don’t have empty objects with additional fonts in your file.

  • Provide a dummy—I’m not referring to the kind of dummy that a ventriloquist uses. A dummy is a printed mockup that shows a printer how a job should look when it’s printed and folded. It doesn’t have to be in color or even full size, but it should give the printer a good visual of what you expect. Creating a dummy also helps you, the designer, because you can make sure that the panels fold correctly and are the right size.

InDesign’s Package Feature

InDesign’s Package feature is a great way to prepare a project to hand off to your printer. This feature (found in InDesign’s File menu) creates a folder that contains a copy of your file, along with all the fonts and linked images that are used in your file. It also enables you to easily create a text file with instructions that you can pass on to your printer.

I’ve found that it’s also good practice to send along a PDF version of your file so that the printer can see what the file looks like and compare it to what he sees in InDesign, making sure that everything is correct.

InDesign and Acrobat’s Separation Preview Feature

Both InDesign and Acrobat Professional enable you to view color separations onscreen and also feature a densitometer reading for checking ink coverage. To make sure that your process or spot colors are separating correctly, these are invaluable tools that should be used. If you aren’t sure what you should be looking for when viewing separations, speak to your printer.

Resources

Plenty of material on this topic is available, and it would only benefit you to find some time to learn more about the printing process, as well as understand how art goes from the computer monitor to the printed page (and everything that happens in between).

Here’s a list of some resources that I find useful on this subject. Visit www.designresponsibly.com for the latest updated list.

Finally—and I can’t emphasize this enough—talk to your printer. An open line of communication between designer and printer is crucial and can save time, energy, money, and sanity. If possible, arrange to spend a day or two at a printer and see the process for yourself. Learn about the issues that come up and how they are addressed. The information you will learn will prove more valuable than you can imagine.
