Print Color Accurately

 

Basic Principles

All accurate-printing methods rely on color management, which means the printer must be properly profiled using an ICC profile. The same technology applies to inexpensive desktop printers as well as high-end industrial devices. In every case, the profile defines how the printer behaves with a specific set of parameters — resolution, print speed, screening method, and the chosen substrate (e.g., paper).
This profile is valid only for that exact combination. When creating a profile, always record and save all settings to prevent accidental changes.

A critical requirement is that the printer be repeatable and consistent. If you print the same color across a page, the results should be uniform (known as intra-page variation) and remain stable from sheet to sheet (inter-page variation). Generally, inkjet printers are more consistent than laser devices.

The ICC profile also defines the device gamut, the range of colors that the printer can reproduce under the given conditions.
Only colors inside this gamut can be printed accurately.

A. ICC Profile Only

This is the simplest method — less accurate but faster and requiring fewer resources.
To use this approach, create an ICC profile for your printer. Supported profile types include RGB, CMYK, and nCLR.

If your measurement device includes profiling software, use it. If not, you can create profiles using ChromaChecker, although this may require a subscription.

You may also try ICC profiles supplied by paper or printer manufacturers; however, these often lack the precision required for demanding work.
A custom ICC profile is highly recommended.

B. LUT Technology

This method expands on the ICC profile by performing a series of iterative corrections. Each iteration refines the accuracy of individual colors. A LUT (Look-Up Table) is a text file containing the adjustments needed to achieve the best match.

ChromaChecker provides a comprehensive Color Match solution based on LUT technology. To use it, you will need:

  • A color printer
  • A compatible measurement instrument connected to CC Capture (see compatibility list)
  • CC Capture software with an active subscription

For detailed guidance on using LUTs, refer to the ChromaChecker Manual.
