About IndiGlow Technology
IndiGlow and IndiGlowUp are HP Indigo's extended color gamut technologies that expand the reproducible color range beyond standard CMYK. By adding fluorescent pink ink passes and optional extra cyan/yellow hits, these techniques achieve vibrant colors that would otherwise be impossible to print using traditional four-color process.
IndiGlow adds two passes of fluorescent pink ink to standard CMYK, dramatically expanding the gamut for saturated pinks, purples, and oranges. IndiGlowUp goes further by adding extra cyan and yellow passes, achieving an even wider gamut with exceptional vibrancy across the entire color spectrum.
Best Practices
- Color Mode: Submit files in RGB or Lab color mode. The HP Indigo press uses ColorUp technology to automatically generate extended gamut separations.
- Color Expectations: IndiGlow excels at reproducing saturated pinks, purples, and oranges that fall outside the standard CMYK gamut.
- Substrate Selection: Brighter white substrates produce more vibrant color reproduction with IndiGlow technology.
- Coverage: For maximum vibrancy, ensure fluorescent areas have sufficient coverage (typically 100% for FL Pink layers).
File Setup
IndiGlow and IndiGlowUp require no special file preparation. Simply submit your artwork in RGB or Lab color mode and the HP Indigo press will automatically generate the extended gamut separations needed to reproduce your colors with maximum vibrancy.
For best results, embed your color profile and avoid pre-converting to CMYK, as this limits the color range before the extended gamut processing can take effect.
