@daleif I added RGB to color as some drivers (Y&Y if I recall correctly) used that as the native syntax, can't recall ever being asked for a CMYK version.
@DavidCarlisle our design office specifies colors in base 255, is there a tracker where I can add a feature request. CMYK colors for printing is a huge pain in LaTeX, I can never get them to look right.
@daleif it would need to be in xcolor rather than color thee days so:

I have a beach flag design I want to do. It can hit the correct BG color in RGB, but the printer wants CMYK and I cannot fhit or verify the correct color.
@PauloCereda I'm primarily on Linux so no Adobe available (do have a Win10 VM though)
The interesting part is that most of our own printers are CMYK, and none of them hit the correct color if I'm playing with cmyk
@PauloCereda I'm not an expert for preflight - I only use it to check if I broke the pdf ;-).
@daleif It's a tool that you get with adobe pro (but also in software from callas which imho actually write the tool) to check various aspects of pdf files.
@UlrikeFischer The interesring part is that our design department has a specification of the color in CMYK, but 255 based) and using CMYK: Coated FOGRAF27 (ISO 12647-2:2004), the latter I have no idea how to apply. Preflight does seem to give the right /255 two digit colors, it just looks completely wrong on screen.
@UlrikeFischer I just do not want to receive and have to pay for something that looks completely the wrong color. We should at least be able to print it correctly on our own CMYK printers, shouldn't we?
Which of the xpdf options should be used? I'm playing with x-1a that does not seem to be getting a color profile.
Hmm, colorspace seems to work a lot better
lol, but definespotcolor is better at hitting a sort of right color if it is given an RGB to begin with, cmyk devided by 255 not so much
@daleif I would have to study the documentation too. I don't have so much to do with colors normally, I only know how to look in the pdf to check what is there and can make a straight face if someone says "colorprofile" ;-).
@UlrikeFischer colorspace seems to work given the fact that I do have a Pantone specification as well. Evince cannot print it correctly (but that seems to be a known issue), adobe acrobat does hit sort of the correct color on our own CMYK printer.
Hi, I have a short question: I'm working on a LaTeX document, often I make a mistake and the document doesn't compile, when I fix this mistake and compile again the compiler "hangs" at a certain point, telling me that
File ended while scanning use of \@writefile. <inserted text> \par l.9 \begin{document} ?
I can then press enter and the file compiles as normal. The next time I compile this message doesn't appear, it only appears directly after a compilation failed or was aborted.
So I'm wondering: What kind of a situation can make this happen?
@s.harp I guessed as much, closing the terminal aborts the running job with no chance for it to flush its write buffers so if it was writing the aux file and you kill it you end up with a half-written command and mis-matched { in the aux file, so when that is input next time bad things happen
@s.harp sometimes the aux file gets corrupted even if you do use x (eg if the error is actually in a section head and tex can not recover while writing the table of contents information) but it is fairly rare, whereas if you kill the program externally from the operating system then any open file might get corrupted in this way.
@s.harp another option is that if the next compilation fails, you can try to enter q. Most times it helps and the compilation after this will be ok. If it does not help, then you have to delete the aux files though.
@daleif -- You can get at least an idea if the color is correct if output printed on three different cmyk printers looks identical. My guess is that color printers at most organizations aren't regularly calibrated, so one isolated example may not be a good test. Maybe the design department is more careful about calibration, so maybe you could persuade them to do a test print when you think you've gotten it right.
@barbarabeeton in CMYK, many printers try to do corrections to meet the standard. The question is how successful they are; and this highly depends on the brand, series, price, ...
@yo' -- I guess I'm really familiar only with the "final" step, at the print shop. There, proper calibration is essential. The "local" printers at AMS were maintained regularly, but color calibration either wasn't careful, or wasn't included, because a color image didn't necessarily come out the same on two different machines. (There was a calibrated proof printer to be used if it mattered.)
@barbarabeeton yeah, of course. I just wanna say that the printer does weird stuff to convert CMYK to the actual inputs to the inks/lasers. Calibration is about it knowing how to convert the data. So I think we're in agreement here :)
Today marks a new day in the 26-year history of Red Hat. IBM has
finalized its acquisition of Red Hat, which will operate as a distinct
unit within IBM.
I'm really confused by the latest LuaTeX development and not sure what should I do. We certainly don't want 5 subtly different LuaTeX engines in TeX Live, right?
@UlrikeFischer Regarding our little exchange in the comments to this answer of yours: It appears that it has been fixed (whether by Will or not I do not know):

@DavidCarlisle As far as I know, one can write quite efficient code in Common Lisp and Haskell, but it sometimes requires deep knowledge of the language. There are plenty of traps for the unwary, especially in Haskell.
@HaraldHanche-Olsen people writing code in assembler as C is not enough control over register use, I can't see suggesting they use haskell would go down well.
@FaheemMitha I have written a bit of Common Lisp, but nothing large, and most of it long ago. I've been meaning to learn Haskell for several years now, but life intervenes.
@JosephWright I read the thread about \cr. It's curious where somebody can arrive in order not to admit having read too much in a control sequence name, showing utter ignorance about the history of TeX, when saying that it was probably developed on a Macintosh, because it used <CR> as record terminator. ROTFL
@DavidCarlisle Also since C API seems to be the API exposed by all systems in use today, any low level library needs to expose a C API to be usable by higher level ones.
I imagine it is a very effective language if you know what you are doing. But knowing takes some doing. And the implementations definitely need much to be desired, particularly from a performance standpoint.
Certainly one cannot fault C and C++ from a performance and memory usage standpoint. And they offer all the control one could desire.
I wouldn't want to the person to tell Karl some software in TeX Live needs Rust/Haskel/Lisp compiler, he was very upset when HarfBuzz stopped building with gcc 4.8.
@HaraldHanche-Olsen yes but writing a few million lines of fortran then calling it from a shell haskell function isn't really "using haskell" (it's useful though and that's how we expose teh functionality to pythin or vba for excel etc)
@HaraldHanche-Olsen Optimization is a fantastic research area when studying compiler techniques, for a wacky definition of fantastic. :) Disclaimer: I like it a lot.
@FaheemMitha It does, opening a medium size document it LibreOffice typically calls HarfBuzz a millions (or may be billions, it was a while since I last measured this) times. Just asking the compiler to optimize HarfBuzz gave measurable performance difference.
@FaheemMitha I find it very pleasant to work with. It's easy to mix various programming styles, and debugging is so much easier since exceptions are handled without rewinding the stack first. Often, one can recover from errors and move on.
@HaraldHanche-Olsen Yes, the integrated debugger is very nice. Though I haven't really learned to use it properly. Much nicer than dumping the user on the floor and leaving him/her to figure out what went wrong. It has other nice features too. I particularly like the handling of scoping, which is typically a nightmare.
And SLIME is super cool, though that's technically not part of the language.
But I suppose if I wanted something to run as fast as possible, it's not what I would be using.
@PauloCereda it does mean a request for "can you compile with the foobar compiler on a widget4 chip architecture" means it takes three months not just type make and come back in the morning....
@Sebastiano -- It's not really polite, so I will just comment. The figure in the car need not be a man; it's inappropriate to assume that it is. (Actually, it looks to me to be a drawing of a crash-test-dummy.)
@barbarabeeton @egreg I have done a compliment for the :-( drawing. I wrote man but it could be a woman. In the Bible the woman is called "uoma". I am not a sexist. But am I the one seeking insults?
@Sebastiano Some people are oversensitive about “political correctness” and pretend not to understand that in a site like this the language barrier can be high. A truly “politically correct” person would have said “please, mind that it could also represent a woman”.

@Sebastiano I didn't defend you I just commented that it wasn't a duplicate (and the duplicate vote was retracted) so you may want to delete your comment
@egreg I wanted put your code as community wiki but I have my name and this i don't no. Can you add another answer, please with your code? That way it's in my question and I don't run the risk of losing it.
@egreg Everything that is culture, knowledge and knowledge is important to me. It is not only necessary to know what is good but also to know how to recognize the validity of what apparently could be not good.
Good evening. Suppose two tables, one very long, more than one page; the other, shorter, it fits in single page. I'd like to put them side by side, aligned by top, that is, both have header aligned at page 1.
I tried supertabular bu the shorter one (on the right) moves to second page.
@Sigur Is this in a two column document? Or are you using multicol? So you want the rest of the second table to appear on the next page? And then what will fill in the rest of the first page?
