Getting your design ready for the printer involves several key technical considerations.
For most commercial printing, your file must be in CMYK colour mode, not RGB. RGB (Red, Green, Blue) is for screens, while CMYK (Cyan, Magenta, Yellow, Key/Black) is the standard for inks used in print. Converting early helps avoid unexpected colour shifts.
Images intended for print require a much higher resolution than those for web. For high-quality results, ensure your images are set to 300 Dots Per Inch (DPI) at their actual print size. Lower resolutions (like 72 DPI for web) will appear pixelated or blurry when printed.
If your design features elements that extend to the very edge of the finished piece, you need to add bleed. This is extra design area that extends beyond the trim line. It accounts for slight variations during the cutting process, preventing unwanted white edges. A standard bleed is typically 3mm (0.125 inches) beyond the trim line. The trim line indicates where the print will be cut.
To ensure your text prints exactly as designed, all fonts must be properly managed. The safest approach is to outline fonts, which converts them into shapes. Alternatively, you can embed all fonts within the file, making sure the printer has access to them. If fonts are not outlined or embedded, the printer's system may substitute them, altering your design.
If you've placed images from external files into your design, ensure they are linked correctly and also meet the 300 DPI resolution requirement. If you embed them, the file size can become very large. Always supply all linked image files alongside your main design file if not embedded.
The choice of file format is crucial for a Print-Ready File. While various formats exist, PDF/X-1a is widely considered the industry standard for commercial printing due to its ability to embed all necessary elements (fonts, images, colour profiles) and maintain consistency. Other acceptable formats may include TIFF, EPS, AI (for vector graphics), or flattened PSD files for raster images. Always check your printer's preferred format.
For complex designs, keeping layers intact in formats like PSD or AI can be helpful for minor adjustments. However, for the final Print-Ready File, some printers may prefer or require flattened files to avoid rendering issues. Clarify this with your printer.
Once your file is technically prepared, the next essential step is proofing the artwork. This involves reviewing a mock-up or digital representation of your design exactly as it will appear in print. Design proofing before printing catches potential errors that even the most meticulous preparation might miss.
During the artwork proofing stage, check for correct colours, legible text and correct fonts, image clarity and positioning, accurate spelling and grammar, and correct dimensions and bleed area.
Never skip this step. A final sign-off on the proof means you accept the design as presented, and any errors found after printing will be your responsibility.
Preparing your digital art for printing correctly is fundamental to achieving high-quality results. Attention to details like colour mode, resolution, bleed, fonts, and file formats lays the groundwork for success. Moreover, thorough artwork proofing is your final safeguard, ensuring your vision translates perfectly from screen to finished product. Following these steps helps guarantee your print-ready artwork makes a powerful and professional impact.
