Assets Tab

then click on

Learn the difference between Library and Pallete here.

The substrate is optional - but most of ColorLibraries today are substrate dependent.

Such a Library is empty. Using the website interface there are a couple of possibilities:

1. Import CxF file which contains Color Library - it might be exported from 3rd-party software
   Drag and drop the CxF file on the Upload icon.
   
   
2. Copy existing Samples from other Libraries/Palettes already in CC Assets
   Open Library or Palette - select samples, click on the "Copy to Palette" button on the bottom
   
   
   
   
3. Use CC Capture to Create Color References with one of three methods:
   
   a.  CC Capture Color Inspector - recommended if CxF/X-4  enhanced spot definition with
         (halftones  printed required)
   
   b. QuickChecker Scracthbook measurements
       — fast but might be less accurate - as single measurements may not reflect the sample properly
   
   c. QuickChecker Start Variation tool - the best way to create an average from measurements
       — instant variation analysis ( sample uniformity/homogeneity).
   
   
4. Make manual input (Lab values only). We do not recommend this method.
