Color Sample Matching

1. Load
Select the Load button to load the PDF source file and the scanned hard copy sample.
2. PDF Source File
Load the PDF source file. The application displays the image of the loaded file.
  • Select File: Select the PDF source file. For details about the supported file formats, see Supported File Formats.
  • Select Area: Select the image orientation by rotating it clockwise or counterclockwise. Then, select the image area for which you want to match colors.
  • Previous pageNext page: Select to move to the previous or next page.
3. Save
Select to save the files containing the source PDF and the scanned data of the hard copy sample. This action allows you to reuse the loaded PDF source file and the scanned hard copy sample, without keeping the hard copy sample and scanning it again.
    Note:
  • This button is active only after the color sample matching is complete.
4. Hard Copy Sample
Place the hard copy sample on the input tray and select Scan. After the scanning process is complete, the scanned image is displayed in the Hard Copy Sample section.
  • Paper Size - Feed Direction, Sub-Scan Length: Select the paper size of the hard copy sample in the feed direction. If you select Custom Size, enter the paper length along the sub-scan direction from 210 through 487.7 mm (from 8.3 through 19.2 inches) in the Sub-Scan Length field.
      Note:
    • The outermost 30 mm (1.2 inches) of paper edges in the sub-scan direction are not read by the scanner. For details about the scan area, see Paper Specifications.
    Placing the hard copy sample on the scanner
  • Scan: Scan the hard copy sample.
  • Select Area: Select the same image orientation and area that you selected in the PDF Source File section.
  • Delete: Select to delete the scanned image.
5. Printed Reference Sample
Place the printed reference sample on the input tray and select Scan. After the scanning process is complete, the scanned image is displayed in the Printed Reference Sample section.

  • Settings: Select to adjust the amount of image data that is processed while executing the Color Sample Matching process.
  • CMYK Source Profile, CMYK Rendering Intent: Select the source profile and rendering intent for printing the PDF file.
7. Show ΔE Map
Visually inspect the color deviation. Printed Reference Sample displays the color deviation map before applying color matching. Color Matching displays the map after you apply color matching. The white areas in the color deviation map indicate colors that have a large deviation in color. The color deviation is calculated by subtracting the value of paper color and truncating the decimals.
8. ΔE Map Details
Visually inspect the details of the color deviation map to see how the adjustment of the color matching settings affects the color matching result. The whiter the areas, the larger the color difference.
9. Average Color Deviation
Displays the calculated average color deviation before and after matching colors. The average color deviation is derived by calculating the average color deviation value of all pixels in the image.
10. Save ICC Profile
Select to save the ICC profile that is generated after executing a color matching process.
