Current proofing systems can reproduce spot colors such as HKS or Pantone very well. With the Fiery XF 6.5.2 proofing software and the Epson SureColor-P9000V Spectro proof printer, we have evaluated the color deviation in Delta-E00 with which the various PANTONE and HKS colors can be proofed. A distinction is made between the proof papers we use, since the surface quality and the paper white also influence the representability of the colors.
The color deviations were calculated by the proofing software on the basis of the measured color space of the proof.de proofing system. Deviations are therefore possible in practice. However, it turns out that almost all spot colors can be simulated quite well in the large color space of the proofing device.
The smaller the ∆E00 value, the smaller the color distance from the spot color reference to the proofed color. Higher ∆E values show which colors can be reproduced more poorly in the proof.
As a rough guide: From ∆E00 > 1 a color difference is visible to the human eye, below it it can only be measured, but not seen.
