CMYK is the baseline
CMYK is the standard four-colour process for everyday UV production. It is the right starting point when the substrate is light and the job does not depend on extra opacity, wider gamut, or special surface effects.

UV color range
Understand what each channel changes in color, opacity, finish, and adhesion. Once the channel logic is clear, open Configurations to compare the real inkset combinations and layouts.
Core color channels
These channels shape gamut, tonal smoothness, and grayscale behavior before you add functional layers.
Light Cyan + Light Magenta smooth gradients
Light Cyan and Light Magenta reduce graininess and improve subtle transitions in photographic, cosmetic, and premium visual work where standard CMYK can look rougher in light tones.
Light Black refines grayscale
Light Black improves grayscale neutrality and subtle dark transitions. It matters when the print depends on smooth monochrome rendering or delicate shadow detail rather than bold process-colour contrast.
Orange + Violet extend the gamut
Orange expands warm tones and Violet deepens cool ones. Use them when brand colors, retail graphics, and premium visuals need stronger oranges, violets, and more accurate color matching than CMYK alone can deliver.
Functional channels
White, varnish, and primer solve opacity, finish, and adhesion problems that standard process color alone cannot solve.
White adds opacity and underbase strength
White creates an opaque base on dark, transparent, metallic, or colored materials. Without it, process colors can lose strength, contrast, and accuracy because the background shows through.
Varnish changes finish and texture
Varnish is the clear channel for gloss, matte, tactile texture, and additional surface protection. It does not expand the gamut, but it changes how the finished print looks and feels.
Primer improves adhesion
Primer is the functional channel for difficult surfaces such as glass, metal, and selected plastics. It is used when reliable ink bonding is the first problem to solve.
Choose the real inkset next
Once you know which channels matter, compare the actual combinations, rows, and layouts in Configurations.
Configurations
Open Configurations to compare the real CMYK, White, Varnish, Light-ink, Orange/Violet, and Primer combinations by rows, groups, and head count.
