RGB vs CMYK for Business Card Printing: How to Export the Right File

The most common technical mistake in business card design is exporting in RGB and assuming the printer's software will convert it accurately. Sometimes it will. Often it won't, especially for specific brand colors.

The short version

• RGB — the color system used by screens (monitors, phones, TVs). Produces more vivid colors.
• CMYK — the color system used by commercial printers. Narrower range.
• Problem — some RGB colors have no exact CMYK equivalent. When converted, they shift to the closest printable color, which can look noticeably different.
• Solution — design and export in CMYK from the start.

How to tell if your file is RGB or CMYK

In Adobe Illustrator: Check File > Document Color Mode. It shows RGB or CMYK.

In Adobe Photoshop: Check Image > Mode.

In Canva: Canva works in RGB by default. When you export "PDF Print," Canva converts to CMYK automatically — but the conversion quality can vary.

PDF files: Open in Acrobat, go to Tools > Print Production > Output Preview to see the color space.

How to export a business card correctly

From Illustrator:

1. Set the document color mode to CMYK (File > Document Color Mode > CMYK)
2. File > Save As > Adobe PDF
3. Use the "Press Quality" or "PDF/X-1a" preset
4. Under Output, set Color Conversion to "No Conversion" (you've already set CMYK)
5. Include bleed marks if using the Marks and Bleeds panel

From InDesign: Same as Illustrator — work in CMYK, export PDF/X-1a.

From Photoshop: Image > Mode > CMYK Color, then Export > Save as PDF at 300 DPI.

From Canva: Download as "PDF Print." Canva handles the CMYK conversion. Check that your brand colors look correct in the downloaded PDF before uploading.

Colors that shift most dramatically RGB to CMYK

• Vivid electric blues and greens
• Neon colors of any kind
• Saturated purples (often shift toward maroon or navy)
• Some oranges

If your brand uses any of these, check the CMYK proof carefully. The shift can be significant.

Checking your CMYK values

If you have specific brand CMYK values (your brand guide should include them), enter them directly in your design software rather than relying on hex-to-CMYK conversion. Direct CMYK entry is always more accurate than conversion.

If you don't have CMYK brand values, convert once in Illustrator, note the output values, and use those consistently across all print materials.
