Print Design: Everything You Need to Know Before Going to Print

You've finished your design. You sent it to the print shop. A few days later, the file came back: colors faded, edges misaligned, PDF incompatible. It happens to everyone. Once is enough.

Print design is a different discipline from screen design. Pixels can be deceiving; paper is not. A design that looks flawless on screen can come out of the printer as a disappointment without the right technical preparation.

CMYK, bleed, resolution, PDF/X. These are not details, they are the foundation of the job.

In this guide, we take a step-by-step look at the technical requirements of print design, common mistakes, and how to establish a smooth workflow with the right tools. By the end of the guide, you will know both what to do and which app to use to do it best.

Right on screen, wrong on paper… Why?

Your monitor works with light. The printer works with ink. This difference changes everything in the world of design.

RGB or CMYK?

RGB (red, green, blue) is a color model designed for screens. It produces millions of colors through light mixing. CMYK, on the other hand, works by layering four ink colors (cyan, magenta, yellow, black). While the RGB CMYK difference may seem like a mere technical detail, the result can be dramatic: when you design in RGB mode and then convert, colors fade, shift, or change completely.

Starting your design in CMYK print mode is the only reliable way to avoid these surprises. Understanding CMYK conversion is essential, when you convert RGB to CMYK at the last minute, you lose control over how colors will translate to ink on paper.

Resolution: Sharp on screen, blurry in print

Understanding DPI vs PPI is crucial for print design. 72 DPI (dots per inch) is sufficient for the web, but PPI (pixels per inch) measures screen resolution while DPI measures print output. The minimum standard for print resolution is 300 DPI.

A low-resolution image that appears clear on a monitor will appear pixelated on paper if it does not meet the print resolution standard. Checking the resolution during the design phase is one of the first steps that must be taken before sending the file to the printer.

Color consistency and Pantone

CMYK print may be insufficient to represent a wide range of colors. The Pantone color system uses spot colors that come into play in corporate identity projects or in situations where it is critical that a specific color appears exactly the same in every print.

Not every printer supports the Pantone color system; confirming this before requesting a quote will make the process easier later on.

Technical Requirements

Printing requirements are not arbitrary. There is a reason for every technical value. After reading this section, you will no longer ask 'why 3mm?'

Bleed

When paper is cut, there may be a millimeter of misalignment. Bleed is extending the design 3mm beyond the cut line. This extension prevents a white edge from appearing when the paper is not cut exactly on the line.

A professional job goes to the printer with bleed. If it doesn't, it comes back. The standard bleed is 3mm added to each edge. Pro tip: Always consult your printer for bound or special formats. Understanding proper bleed setup is one of the most important aspects of professional print design.

Trim line

The trim line is the actual place where the paper will be cut. It defines the final size of your design. The area between the trim line and the bleed is the printer's 'maneuvering' area.

Crop marks (also called trim marks) are small lines placed at the corners of your design to show the printer exactly where to cut. When you export your file, always ensure crop marks are visible as these guide the cutting process and ensure your design is trimmed to the exact size you intended.

Safe zone

A 5mm buffer zone inward from the trim line. Text, logos, or critical visual elements should not extend beyond this area. Even if the paper is cut slightly too much, the content in the safe zone will remain intact.

PDF/X formats

PDF/X is a standard developed for printing workflows. PDF/X-1a is the strictest version: all colors must be CMYK or spot colors, and all fonts must be embedded. This ensures the widest printing compatibility.

PDF/X-4 allows transparency, layers, and ICC profiles; it is more flexible for modern digital printing. Your printer will tell you which one they want. If they haven't asked, ask them.

Affinity: The right tools for the job, set up correctly from the start

Affinity is an app unlike anything else in the design world: a unified suite that brings together vector, pixel and editing studios in a single workspace. No switching between separate apps, no file conversions, everything in the same document.

The print workflow is also built into this structure; it is not an afterthought, but a fundamental function. Every step, from color management to print preflight, is designed with printing requirements in mind.

Setting up the document correctly

Starting correctly eliminates the need for corrections later. When you open the new document screen, you can make all critical settings at once on the right side of the panel:

• Enter 300 DPI for proper print resolution
• Select CMYK/8 as the color format for CMYK print
• Enter your final print size in the page width and height fields
• Add 3mm to each edge in the bleed field

Margins can also be set at this stage. The safe area visually defines where text and critical elements can go within the document. You won't have to check later on whether anything has gone over the edge.

Whether you’re working on page layout, vector-based graphic design, or pixel artwork, you can set all these options from Affinity’s New Document screen.

Color Management

Affinity carries color management throughout the document, not just during export. You can change the ICC profile when creating a new document or afterwards via Document › Setup › Convert Format/ICC Profile.

Before starting your project, be sure to ask your printer which ICC profile to use. ICC profiles installed on your operating system are automatically detected by Affinity and can be accessed directly from the ICC profile menu in the Export dialogue.

If you want to see how colors will appear before printing, activate the Soft Proof adjustment layer. This simulates the output on your screen according to your selected output profile, significantly reducing the chance of surprises in print.

Typography for print

Many problems in printing arise from typography. Before exporting, open Document › Font Manager; the panel lists all fonts and their statuses in your document, immediately showing any missing ones.

If you want to avoid font issues entirely, convert text to vectors, but leave this until the very last step; do it after all text editing is complete. Text smaller than 6pt is often unreadable in print; 9-10pt is a good starting point for long texts.

Line spacing that looks comfortable on screen may appear cramped on paper; taking a test print is a simple but still useful habit when working on typography for print.

Image Placement and Resolution Control

Instead of copying and pasting images, place them using the Place... command. This way, the files remain linked to the document and the resolution information is preserved.

Document › Resource Manager lists the DPI value of all linked images on a single screen and flags those below 300 DPI. To avoid issues during printing, we recommend checking the print resolution values of images before exporting. This helps you catch any low-resolution images that would appear pixelated in print.

Preflight

An automatic check you should run before sending your file. Affinity’s built-in preflight panel detects low-resolution or missing images, missing fonts, elements in RGB mode, and content that bleeds outside the trim area.

Open the panel via Window › Layout › Preflight and correct any flagged issues. If there are no warnings, your file is ready for export. The preflight check is your final quality control before sending to print.

Correct exporting

Final step: File › Export › Export.

In the dialogue box that opens, you will see the PDF formats on the left. For most printers, PDF/X-1a:2003 is the safest option: all colors must be CMYK, and all fonts must be embedded. If your printer accepts PDF/X-4 for modern digital printing workflows, select that.

If you are unsure, the PDF (print-ready) preset is a good starting point. Whichever format you choose, ensure that bleed and crop marks are visible. Before sending, open the file in a PDF reader and review it.

Sending to print

Once the design is complete, it's time to place the print order. For designers who have relationships with agencies or printers, this step is already familiar. But if you're looking for a quick and practical solution, especially for marketing projects like business cards, brochures, flyers, or event materials, Canva Print offers a direct ordering and delivery option.

Get it right, every time

Print design is not the ‘print-ready’ version of screen design. It is a separate discipline with its own rules, technical language and tools. CMYK, bleed, resolution, preflight, PDF/X: these are the mechanisms that ensure you get the right result every time.

The right app integrates these mechanisms into the workflow. With Affinity, vector, pixel and layout studios are all in one workspace, with everything from color management and ICC profile support to print preflight built in. A first in the market.

Understanding the RGB CMYK difference, proper CMYK conversion, setting up bleed and crop marks, managing print resolution (DPI vs PPI), using the Pantone color system when needed, and running preflight checks: these are the foundations of professional print design.

And best of all, this app is completely free.
