LAB Color Matching Calculator

Professional Color Matching Guide

Target Color: Enter the color you want to achieve. Use either CMYK ink percentages or LAB device-independent values.

Sample Color: Enter the color you actually measured or produced. Compare this against your target to see the difference.

Delta E Interpretation:

• ΔE ≤ 1.0: Perfect match (not detectable by human eye)
• ΔE 1.0-2.0: Very good match (slight difference)
• ΔE 2.0-3.5: Good match (acceptable for most commercial work)
• ΔE > 3.5: Poor match (requires adjustment)

Professional Tips:

• Use spectrophotometer measurements for LAB values when possible
• Consider substrate and lighting conditions
• Total ink coverage (TAC) should typically stay below 300%
• Use the step-by-step process view for complex calculations
