FOGRA39 Christmas Presents Here they are, the “Christmas gifts” made by the: the new “FOGRA39”. The associated profiles from the “ISO Coated v2 (ECI)” and “ISO Coated v2 300 (ECI)” will be available in the beginning of January.

FOGRA39 in comparison with FOGRA27 In order to get a first impression, I compared the new and old characterisation data using. The following pictures show the differences between FOGRA27 and FOGRA39 in 3 CIE L*a*b* planes (aL, bL and ab). FOGRA27 chromaticity coordinates are drawn as grey circles, FOGRA39 chromaticity coordinates as black, blue or red circles. The lines connect the same CMYK values in FOGRA27 and 39. The color of the lines classifies the color difference (DELTA E 2000): • Black stands for color differences between 1 and 3, • Blue for color differences between 3 and 5, • Red for color differences above 5.

Obviously the strongest differences appear in the range of dark grey and blue shades, which are shifted towards magenta. The average of all values with ΔE00>5 results in a CMYK value of 96/91/72/14, Lab 24.6/4.3/6.8 for FOGRA27 and Lab 24.5/1.3/7.9 for FOGRA39. The most significant change is a shift of Δa 5.5 towards magenta. Grey balance A more detailed review of the ECI2002 tables shows that these changes are manly caused by the new grey balance and the modified chromaticity coordinates for blue: The CMYK value 100/100/100/0 was apparently greenish (C = 7, h = 170°) and is now perfectly neutral (C = 0). With a ΔE00 of 7. Vermicompost In India Pdf. 4 it is on rank 4 of 1457 in a.

Rank 1 to 3 goes to the CMYK values 100/100/70/0, 100/100/70/20 and 100/100/85/0 — very dark shades of blue with few or no black. Their ΔE00 amounts to 8.2 through 7.9. The brightness is hardly changed (ΔL 0.20.7), but with ΔH = 6 they are obviously more violet. Rank 19 shows a dark shade of green for the first time: CMYK 100/85/100/0 becomes substantially more neutral with ΔE00 = 5.4 and ΔC = -6.7 in FOGRA39 due to the changed grey balance. Shades of blue Rank 28 (CMYK 100/100/0/20) is the first color with maximum black composition: its ΔE00 amounts to 4.6 and with ΔLab 0.8/5.7/1.4 it became considerably more violet. Other shades of blue like CMYK 100/100/0/0 (ΔE00 = 4.4/Δa = 5.8, rank 38), CMYK 100/ 85/0/0 (ΔE00 = 4.2/Δa = 5.2, rank 45) and CMYK 100/ 70/0/0 (ΔE00 = 4.2/Δa = 4.2, rank 89) show the same trend.
