Many are waiting for the report regarding how to get scientifically calculated TIC's for every colour individually and how to optimize the use of ink in general (what some people call "save ink"). It must be coming soon. Was supposed to meet the pretty blond lady who wrote it but had to travel.

Sorry for the delay. Maybe I should print it and hand it out at Drupa...

Anyway, I have not got it yet so while you are waiting you can suck (as on candy) on this.

Bored at the airport in Houston and inspired by the nearby US Colour Space Centre I played aorund a bit. More nerdy things that might give something for the gray cells:

Example values for neutral black, Lab 0, 0, 0 (like a black hole in space...)

Results with ISO Coated v2 (ECI).icc:

Relative (no black point comp; normally more exact conversion and mode for measurements)

Results with ISO Coated v2 (ECI) recalculated in other software* (no name mentioned, said if before, refuse to mention products since discussion then usually become emotional) with same TIC (330):

Relative (no black point comp)

Examples of constructed neutral blacks based on the ISO Coated v2 (ECI) profile/measurement

(I was lazy and put K at 100% in most of the examples, which is ok in coated offset):

CMYK 93 82 59 100

TIC: 334

Lab 10 0 0 !

(Compare this example or the one below with the "300%"-version of the ISO Coated v2 (ECI) that give Lab 13 0 1 at TIC 300%!)

Houston we have a problem... the space is not as black as it could be...

Why does not the ICC-profiles give us a neutral black?

Why does not the ICC-profiles give us the best possible neutral black?

As said before: maybe TIC 234% could be good for a neutral black but not for a dark saturated green...

Why make a compromises?

If you would allow one (1) in difference for L you would print with a TIC of 275% and if you would allow two (2) in difference for L you would print with a TIC of 234%.

Drying time guys and gals, drying time...

Recalculate your ISO Coated v2 (ECI) and have a better chance to reach a better black: you will have values on the plates that will make it possible to print a more neutral black and also even more black.

Do like we do; print better than ISO Coated v2 (ECI) (high pigment ink and slightly higher densities (Lab in neutral black end up at 9 0 0); convert your ISO-jobs to press profile; allow 1 difference in L and print with a TIC at 233% with a final L of 10 (in neutral black)!

Tada: Same colour as ISO Coated v2 (ECI), slightly better range (L) and with less ink.

And then I have not even mentioned all the other colours, here I only talk about TIC.

(Note: this require a special software, it is not enough with a an ICC-profile).

More. Try this at home:

*/ Download here and try the recalculated version of ISO Coated v2 (ECI):

ISO Coated v2 (Alter Schwede) 330

ISO Coated v2 (Alter Schwede) 300

Basically gives more accurate conversions; TO THE SAME PRINTING STANDARD. (Please do not tell me it is not "the standard", have had that discussion to many times... It is just B to A that is different. A to B can differ a little bit but most profiling softwares triangulate the measurements in a simular way.)

Cheers from US and A

Dear all,

please immediately STOP requesting the essay from Seb A over the
mailing list. Either contact him directly by private email, or wait
for his post where he might just offer a download link (as he has
promised to find out whether he can do it, as the essay is not his,
but somebody else's).
