A great printed piece starts before it ever reaches the printer. A strong prepress checklist helps you catch small issues like blurry images, missing bleed, RGB colors or awkward text spacing before they become expensive reprints.
Use this guide as your go-to print prep checklist for standard marketing materials like business cards, brochures, flyers, booklets and other everyday pieces. You’ll learn what prepress means, which file settings matter most and how to export a print-ready PDF with confidence.
- A prepress checklist helps you catch file, layout and formatting issues before printing.
- Most standard print projects need 300 DPI images, CMYK color and proper bleed.
- Proofread both the words and the visual layout before exporting.
- Multi-page pieces need extra checks for page order, margins, imposition and binding space.
- A high-resolution PDF is usually the best final file format for print.
What is prepress?
Prepress is the final review and setup stage before a design is printed. It includes proofreading, image resolution, color mode, bleed, trim, crop marks, margins, font handling and file export.
Think of it as the “measure twice, print once” step. Whether you’re creating business cards, brochures, flyers or booklets, prepress helps make sure your finished piece looks the way it did in your design file.
Proofread everything
Small oversights, such as typos and grammatical errors, can be the difference between closing a sale and a customer choosing the competition. And in print, there’s no quick edit button once your design is in customers’ hands.
There are two types of proofreading to check before sending your file to print. Linguistic proofreading covers grammar, spelling, typos, punctuation and general flow. Prepress proofreading, or graphic proofreading, looks at how the text appears visually, including awkward line breaks, uneven spacing and text that sits too close to the edge.
Before exporting, check:
- Names, dates, prices, phone numbers, URLs and QR codes.
- Headlines, subheads and calls to action.
- Widows, orphans and awkward line breaks.
- Text that sits too close to the trim edge.
- Consistent spelling, capitalization and punctuation.
Check typography, font spacing and readability
Once the words are proofread, look at how they sit on the page. Most design programs apply basic spacing automatically, but your eye still matters.
Adjusting leading, tracking and kerning can make text feel more polished and easier to read. This is especially important for text-heavy pieces like menus, brochures and booklets. Body copy should be large enough to read comfortably, line spacing should give the text room to breathe and important information should not feel squeezed into tight spaces.
For folded pieces, keep key text away from fold lines so nothing important disappears into the crease.
Confirm image size and resolution
Double-check the resolution of your imagery before printing. For most standard print projects, images should be saved at 300 DPI at the final printed size.
Avoid enlarging photos too much, since stretching an image lowers its effective resolution and can make it look soft or pixelated. This is important for photo-heavy brochures, flyers, posters and other printed pieces where sharp visuals help your design present as professional.
This is also where raster vs. vector images matter. Photos are usually raster images, which means they are made of pixels and can blur if stretched too far. Logos, icons and illustrations are often vector files, which can scale cleanly without losing sharpness. Use vector artwork where possible and high-resolution raster images where photos are needed.
Use CMYK color mode
What you see on screen is not always what you get in print. Screens use RGB color, while most printers use CMYK.
RGB uses red, green and blue light for digital displays. CMYK uses cyan, magenta, yellow and black ink for printed pieces. If your design is left in RGB, the colors may shift when converted for print, so set your file to CMYK when the design tool allows it.
If you want to learn more about the difference between the two, check out this blog post on RGB vs. CMYK or watch the video below. The basic takeaway is simple: Your computer and printer need to speak the same color language.
Rich black vs. flat black
Not all black prints the same way. Flat black usually means 100% black ink only, often written as C0 M0 Y0 K100. It works well for small text, thin lines and detailed elements.
Rich black mixes black with other CMYK inks, such as C60 M40 Y40 K100, to create a deeper black for large background areas. This is a common pain point for designers whose blacks appear washed out when printed. Though avoid using rich black for tiny text, because slight ink shifts can make the edges look fuzzy.
Calibrate your screens
Color can look different from screen to screen, especially if monitors are calibrated differently. That can make it tricky to judge the true tone of your design before printing.
Viewing your design on more than one device can help you spot obvious color or contrast issues. Even better, print a test copy or order a proof when available. A proof will not always match the final print perfectly, but it can help you catch readability and layout problems before placing a full order.
What are bleed, trim, crop marks and safe zones?
Bleed, trim, crop marks and safe zones help your design move cleanly from screen to paper.
Crop marks show where the piece should be cut. Bleed is the extra artwork that extends past the trim edge, so your design can print all the way to the edge. A common bleed size is 0.125 inches on each side, though you should always check the exact product requirements before uploading.
The safe zone is the area inside the trim where important text, logos and details should stay. Background colors and images can extend into the bleed, but anything customers need to read should stay safely inside the finished edge.
Skipping bleed can leave an unwanted white border around your design. Placing text too close to the trim edge can make the layout feel cramped, or worse, risk cutting off important information.

Prepare multi-page files, imposition and binding space
In printing, imposition is the process of arranging pages so they print, fold and bind in the correct order. It matters most for booklets, catalogs, folded brochures and other multi-page pieces. Modern design tools make imposition easier, but multi-page files still need careful setup. Check page order, page count, inside margins and gutter space before exporting.
The gutter is the inner margin near the binding or fold. If it is too narrow, text and images can feel cramped or get pulled into the fold. Add a little extra space near the center of bound or folded pieces so the final design is easy to read.
Package your file before handing it off
If you are sending editable files to a designer, client, teammate or print partner, make sure the full project is included, not just the layout file.
InDesign’s Package feature
In Adobe InDesign, the Package feature gathers your layout file, linked images and fonts into one folder. This helps prevent missing-font and missing-image issues when someone else opens the project.
Packaging is especially useful for larger or more complex print projects. A layout file on its own may not include the images or typefaces used in the design, so packaging keeps the full project tidy and easier to troubleshoot.
Create a high-resolution PDF
Once your file is checked, export a high-resolution PDF. PDF files are one of the best formats for print because they preserve your layout, fonts, images and spacing.
Use a high-quality or press-quality export setting, include bleed if your design uses it and avoid compressing images too much. Before uploading, open the PDF and check image sharpness, page order, text placement and final size one more time.

Select the perfect paper
The right paper can change how your design feels in someone’s hand. Before ordering, think about the impression you want to create.
When comparing types of printing paper, consider finish, texture, paper thickness and weight. A lighter paper can work well for simple handouts, while sturdier stock can make business cards, folded cards or premium mailers feel more polished. Glossy finishes can help photos pop, while matte finishes are often softer and easier to write on.
Common prepress red flags
Going through prepress helps you protect your design from small mistakes that become big problems in print. Before you submit your file, watch for these common issues:
- Images under 300 DPI.
- RGB colors in a file intended for print.
- Missing or incorrect bleed.
- Text too close to the trim edge.
- Fonts that have not been embedded, outlined or packaged.
- Low-contrast text that is hard to read.
- Incorrect page order in multi-page files.
- Too little gutter space near folds or binding.
- QR codes, URLs or contact details that have not been tested.
- Files exported at the wrong size or in the wrong format.
Don’t be pressed with your prepress
Print prep does not need to be intimidating. Once you know the basics, like proofreading carefully, using 300 DPI images, setting your file to CMYK, adding bleed, respecting the safe zone and exporting a high-resolution PDF, you can send your design to print with much more confidence.
A little prepress time upfront can save money, protect your design and help your finished piece look as polished as you pictured it.
