Designing for print is very different than designing for web browsers. On the web, you don't have to worry about margins, bleeding inks, or resolution limits. In this guide, we cover the essential tips every graphic designer needs to know to prepare print-ready design files.
1. Set the Document Mode to CMYK
Always set your design software document profile to CMYK instead of RGB before starting your print project. This ensures that the colors you see on screen are restricted to the gamut that standard printing inks can produce, preventing unexpected dull colors after printing.
2. Use High Resolution (300 DPI)
For screen displays, a resolution of 72 DPI is standard. However, for printing, your images and bitmap graphics must be at least 300 DPI at their final print size. Low-resolution images will look pixelated, blurry, and unprofessional when printed.
3. Set Bleed and Safe Zones
When printing files are cut to size in print shops, cutting machines can shift slightly. To prevent ugly white borders, extend your background colors beyond the cut line—this area is called the "bleed" (typically 3mm or 0.125 inches). Keep all critical text and logos inside the "safe zone" (3mm inside the cut line) so they don't get accidentally trimmed off.
4. Keep Text Legible
Avoid using tiny font sizes (under 6pt) or thin fonts over dark backgrounds, as printing inks can bleed slightly into the paper, causing the text to look blurry or unreadable. For pure black text, set the color value to 100% K (Key/Black) rather than using a rich black mix, ensuring clean and sharp lettering.
