RGB vs CMYK | Spot Colors | Duotone | Grayscale | Gradients | Resolution | Bleed & Border | File Formats | Font Types

Grayscale

For single color jobs, using either grayscale or a Pantone spot color, convert your images to grayscale first.

Grayscale Values

Please note that Red and Green have similar grayscale value, so your images may need to be edited to increase contrast after they've been converted to grayscale.

Rich Black vs Black

For CMYK Jobs, use Rich Black for large black areas, or they will appear dull. For all jobs, only use 100% black for text; use of rich black for text will cause registration problems.
