"Print images and PDF documents in ColorSync Utility on Mac

When printing an image or a PDF document with ColorSync Utility, you can choose advanced options for managing the document’s colors, or you can print the document without any color management.

1. In the ColorSync Utility app  on your Mac, choose File > Open, then select an image or PDF document.
2. When the file opens, choose File > Print, then click the arrow  next to ColorSync Utility to show the options (if they're not already showing).
3. Click the Color pop-up menu, then choose an option:

• Prematch to printer profile: Controls the color management of the printed output.
• Hand off to printer: Lets the printer control the color management of the printed output.
• Print as color target: Prints the document without any color management. This option is available only if the document uses the same color space as the printer; for example, you’re printing an RGB document on an RGB printer.

4.If you chose “Prematch to printer profile,” click the Intent pop-up menu, then choose one of the following:

• Perceptual: Applies realistic-looking colors, useful for photographs.
• Relative Colorimetric: Maintains color accuracy when specific colors are required for certain images, such as logos.
• Saturation: Maintains the vividness of colors, useful for graphics such as pie charts and bar graphs.
• Absolute Colorimetric: Adjusts the colors to account for the differences in white points.
