Viewing Spot Color Channels in CorelDRAW

This article provides an overview of how spot color channels and separations are viewed and managed in CorelDRAW. It covers the specific types of spot color libraries supported, the tools available to preview individual color separations, and how CorelDRAW handles specialty spot plates such as white inks, varnishes, and custom spot channels in both vector graphics and imported bitmaps.

Supported Spot Color Palettes

CorelDRAW supports a comprehensive range of industry-standard spot color systems. When applied to vector objects or outlines, these colors act as independent color plates rather than process (CMYK) mixes. The primary spot color systems viewable within the application include:

  • Pantone Libraries: Full support for Pantone Formula Guide (Coated and Uncoated), Pantone Pastels & Neons, Pantone Metallics, and the Pantone Fashion, Home + Interiors system.
  • HKS: HKS K, HKS N, HKS Z, and HKS E color palettes commonly used in European commercial printing.
  • Toyo and DIC: Standard spot color libraries predominantly utilized in Asian printing markets.
  • Roland and Specialty Inks: Spot colors designed for digital cut and print workflows, such as Roland VersaWorks Spot Colors (e.g., PerfCutContour, CutContour, White, and Metallic Silver).
  • User-Defined Spot Colors: Custom spot inks created manually by assigning spot properties to any custom swatch for technical applications, such as clear coats, varnishes, or white underbases.

How Spot Color Channels Are Viewed in CorelDRAW

Unlike dedicated raster editors that display spot channels in a persistent layer stack, CorelDRAW manages spot colors as vector object attributes and through output separation previews. You can view and inspect these channels through several dedicated features:

1. The Print Separation Engine

The primary method to isolate and view individual spot channels in CorelDRAW is through the Print Preview interface:

  • Go to File > Print Preview.
  • Switch to the Separations tab.
  • In this view, CorelDRAW lists every active plate in the document. You can selectively enable or disable the process channels (Cyan, Magenta, Yellow, Black) and any active spot color channels to isolate individual spot ink plates and verify coverage.

2. Simulate Overprints and Color Proofing

To view how spot channels interact with underlying artwork on screen:

  • Enable View > Simulate Overprints to preview how overlapping spot inks and process colors blend without converting spot colors to CMYK.
  • Use the Color Proof Settings docker to view soft proofs of spot colors using specific device profiles.

3. Spot Channels in Bitmaps and Corel PHOTO-PAINT

For continuous-tone images containing spot channels (such as monochrome or duotone bitmaps, or PSD files with spot channels):

  • CorelDRAW displays imported multi-channel files that contain dedicated spot channels.
  • To directly view, paint, or edit individual spot color channels pixel-by-pixel, the bitmap can be opened in Corel PHOTO-PAINT, which features a dedicated Channels docker displaying separate monochrome masks for each spot channel alongside process channels.
