Color Inspection: Scan to Scan

What Does This Feature Do?

The Scan to Scan feature is used when comparing two scans for color differences. This ensures color accuracy and consistency with brand guidelines.

Why Use this Feature?

Use ‘Scan to Scan Color Inspection’ to get an accurate Delta E value of the color differences between your files—eliminating human error or the need to use a spectrophotometer. Additionally, Scan to Scan provides more accurate results than a Digital to Scan Inspection.

When To Use It

• When the color point being inspected is at least 5×5 pixels in size—the larger the area, the more accurate the color reading will be.
• When the items being printed are governed by strict color accuracy guidelines.

When Not To Use It

• Do not use if you are unsure whether your Master file contains accurate colors.

Expert Tips

For the best experience when using the Scan to Scan feature:

• Before beginning your inspection, the appropriate scan containing accurate colors needs to be declared as the correct Master file by a power user or administrator, and should be used to inspect against all Sample scans moving forward.
  – The scanned Master file should also be named using a strong naming convention.
• If you are using a sample size less than 5X5 pixels, make sure to select multiple points for the most accurate reading possible.
