CMYK values for black

I know 100% K is not the blackest black, and I know that there are color values that will get me the blackest black, I just misplaced my cheat sheet, and can't remember what they were. I thought sure I could find them through some forum searches, but no luck for the cmyk values.
thanks for your input

Try opening a CMYK Photoshop file with the colour settings as you want them (gloss, newsprint, wotever). Click on the little squares at bottom left of the Foreground/Background sample at the bottom of the Toolbox so that they become black and white. With Info open, read off the CMYK values that Photoshop gives you for black. That way you'll get a pretty good dense black that suits the type of printing you're dealing with.
It's all a question of total ink density and how much undercover removal you want. And that all depends on the sort of paper you're going to be printing on.
Be careful though, if you want to put white lettering on a CMYK black area. If the lettering is small, you will probably need to make a non-overprinting 100%K trap so that the CMYK colours don't flood into the white letters.

Add display of CMYK values for skin tone balancing

Add a toggle to display CMYK values in lieu of RGB under the histogram, or some other method of displaying values. Checking that Y > M is one of the simplest and most reliable ways to verify that skintones appear typical and do not appear sunburned. Even with a calibrated monitor the numbers are worth a check. This is one of the more frequent reasons I fire up Photoshop on images that don't need actual editing.

1. Place PDF in InDesign
2. Make a new CMYK spot color, defined 100C 100M 100Y 100K
3. In Ink Manager, find spot color of the PDF in the list.
4. In the ink alias for this, pull down and select the spot color you created in step 2
5. Still in the Ink Manager - beside the spot color you created in step 2, click once on the spot icon on the left to change it to process
6. Output a new PDF from InDesign
Once you have the InDesign file set up, all the work is done for any future PDF files you place. InDesign simply takes the spot color in the original PDF (ie Pantone 293 C) and maps it to your 100 CMYK spot. The 100 CMYK spot is in turn forced to process by the ink manager (the ink manager can be accessed in the flyout in the swatches panel)

Script to Change swatch CMYK values

Are there any scripts available to change CMYK values of swatches for files in CS3?
I have hundreds, probably thousands of Illustrator EPS files that use swatches all drawn from a total palette of maybe 50 colours.
Each colour is named and has a corresponding CMYK value.
I want to update the CMYK values for all ~50 colours that appears across all these documents. Is there some way I can simply change the CMYK spec of the swatches used by each of these documents by not having to manually open and change the colours etc?
Even a script would be good that could batch process the files?
For example:
File contains a swatch as a named colour like:
Fire Red spec'd as 0, 96, 99, 0
I want to automate changing the CMYK values for all files containing Fire Red to, say, 0, 98, 99, 0
Any ideas? I have searched Google for a couple of days.
Edit: the flavour here is Illustrator for CS3 - both Win and Mac.

I understand EXACTLY what you mean as it's the same thing I need to do, and will probably need to do on future occasions.
Did you get anywhere with this problem?
I have designed a scheme for a textbook I am illustrating (this is what I do for a living and have been doing so for well over a decade using Illustrator).
All colours used in every illustration are based on 7 CMYK Global swatches, usually 100% tints but also 50% 75% and others when required.
Anyway I have done 100 illustrations already based on my template when I realize I'm going to have to darken the green by +10% cyan.
What I need is a script to change the definition of my global 'green' swatch in every document from 100Y 30C to 100Y 40C.
Actions won't do it.
Any suggestions?

CMYK values differ from PhotoShop

Why are the CMYK values for a given RGB color differ in kuler
from those generated by PhotoShop? What color profiles is Kuler
referencing?
note: I am using the default North America General Purpose 2
settings in PhotoShop CS3, which references sRGB IEC61966-2.1 and
U.S. Web Coated (SWOP) v2.
example: r19 g61 b141 = c87 m57 y0 k45 in kuler and c100 m89
y13 k1 in PhotoShop.

HI, see if this discussion on Kuler and
color
management addresses your question.

Calling for objects with specific CMYK values?

Hello,
I'm trying to build a script that searches for paths that have specific CMYK values within a document and then edits the opacity of that path. I can specify for it to look only for objects that have a CMYK color but get nothing once I try to specify the CMYK values I'm looking for.
Additionally, do I need to specify that the output will be a "new CMYKColor", or will it suffice to say "paths[i].fillColor.back = 100.0", for example, in the output. Here's what I have for this particular function:
var docRef = app.activeDocument;
var paths = docRef.pathItems;
for (i=0; i< paths.length; i++) {
if (paths[i].fillColor.typename == "CMYKColor" ) {
if (paths[i].fillColor.cyan == 0.0 &&
paths[i].fillColor.magenta == 0.0 &&
paths[i].fillColor.yellow == 0.0 &&
paths[i].fillColor.black == 20.0 &&
paths[i].opacity == 100.0) {
var NewColor = new CMYKColor ();
NewColor.cyan = 0.0;
NewColor.magenta = 0.0;
NewColor.yellow = 0.0;
NewColor.black = 100.0;
paths[i].opacity = 20;
else {
alert ("Object(s) not recognized.")
else {
alert ("Object not CMYK.")
Thank you.

Hi Silly-V,
no, thats's not odd.
Illustrator is a little bit crazy. The most values should be rounded when reading. (like in this thread: Re: Working on a script that will add a new artboard and delete the old one if it is not a specific size)
And so Luis Oyola can do something like that:
var docRef = app.activeDocument;
var paths = docRef.pathItems;
for (i=0; i< paths.length; i++) {
    if (paths[i].fillColor.typename == "CMYKColor" ) {
        if (Math.round(paths[i].fillColor.cyan) == 0.0 &&
            Math.round(paths[i].fillColor.magenta) == 0.0 &&
            Math.round(paths[i].fillColor.yellow) == 0.0 &&
            Math.round(paths[i].fillColor.black) == 20.0 &&
            Math.round(paths[i].opacity) == 100.0) {
                paths[i].fillColor.black = 100;
                paths[i].opacity = 20;
                } else {
                    alert ("Object(s) not recognized.");
                } else {
                    alert ("Object not CMYK.");

[AS] Can't Find a CMYK Value Properly

I can't get Apple Script to recognize a CMYK color on a stroke. I'm trying to write a script that will step through page items in an AI file and, if it comes across items with certain CMYK values, change the values of those items.
But I'm coming across this weirdness:
If I get properties of an item, I can see that the color of a given stroke is:
stroke color:{class:CMYK color info, cyan:0.0, Zoom:100.0, yellow:100.0, black:0.0}
However, this following script does not successfully find the very same colored stroke even though the stroke color is exactly the same as that found when I used get preoperties. What's going on here. Is it a syntax error on my part or a bug?
tell
application "Adobe Illustrator"
tell
current document
tell
layer 1
set theList
to
every
page item
of
it
repeat
with x
from 1
to

end

end

end

end

Thanks Simon and Larry. The problem was one of my OSAXs. I removed my scripting additions and restarted and the mysterious "Zoom" is gone. We're back to magenta in the magenta slot.
Now the script works perfectly. Two follow-up questions though, if you have time:
1. I want to make sure where Larry was going with his setting "selected of item k" to true. It sounds like the plan is to iterate though all objects, select those that meet the criteria and then change that criteria (in this case a color property) once. Is this faster than a script that would find an object and change its color property before moving on and finding the next object? Is one way better than the other for any other reasons?
2. This one's tougher. I've noticed that if I create a CMYK swatch in AI and then apply that swatch to an object and then get properties of that object, the CMYK values of that object differ minutely from what I created. For example, if I create a C=10, M=20, Y=30, K=40 swatch and then get properties on an object I've applied it to, the color might actually be:
stroke color:{class:CMYK color info, cyan:10.000002384186, magenta:19.999998807907, yellow:30.000001192093, black:39.999997615814}
I guess this probably has something to do with color space or gamuts or something. But what I really want to know is can how I can test for a color that I think is 10/20/30/40 and find it even if it's really 10.000002384186/19.999998807907/30.000001192093/39.999997615814.
Is the only way to do this to get the color info for an item into a list or record and then round them to nearest 2-digit number or is there an easier way to handle this?
Thanks.

Script to convert RGB values to CMYK values

I want a script that can help me convert RGB value to CMYK values.
I've seen this thread which explains a script to round up and down:
http://forums.adobe.com/thread/1079041
but is there a script that i can actually define lets say the colour is yellow and in RGB it looks ok because its in RGB mode so you change it to CMYK and you have 6% - 9% cyan and you only want yellow
is there a script out there that i can say
if
cyan = 6%
yellow = 80%
magenta = 0%
black = 0%
then change to
cyan = 0%
yellow = 80&
mangenta = 0%
black = 0%
I don't mind writting the code for each colour that needs to be converted as it would only need defining once but how would i make this script?
any clues?

Hi Carlos,
I've got a bit further with applescript as i've used it a little but i've got an error this is my code so far:

          if exists color is equal to "C=0 M=0 Y=0 K=90" then

The error i'm getting is "can't get color"
the color is there however i believe i must not be using the correct variable any clues?

How can I make the combo box turn to the value of black.

When the show button is pressed (and not before), a filled black square should be
displayed in the display area. The combo box (or drop down list) that enables the user to choose the colour of
the displayed shape and the altering should take effect immediately.When the show button is pressed,
the image should immediately revert to the black square, the combo box should show the value that
correspond to the black.
Now ,the problem is: after I pressed show button, the image is reverted to the black square,but I don't know
how can I make the combo box turn to the value of black.
Any help or hint?Thanks a lot!

Convert from spot color to custom CMYK value in Applescript

I thought this would be very simple and it's not apparently. I am trying to convert a spot color into a custom CMYK value. Basically:
tell application "Adobe Illustrator"
          set theList to every path item of current document
          repeat with k from 1 to count of theList
                    if fill color of item k of theList = {name:"Dark Green"} then
                              set fill color of item k of theList to {cyan:0.0, magenta:100.0, yellow:0.0, black:0.0}
                    end if
          end repeat
end tell
But this script obviously doesn't work. From what I can tell, the fill color simply returns the tint of the item, not the name of it. I can't find anything that returns the name of a spot color so I can set the correct corresponding color. In the above example, I made the color obviously changed so I could visually see the result.
Any advice would be greatly appreciated! I'm a first time poster here.
Thanks!

CMYK value "very" different look

I hope somebody here has an answer for me in this matter, because i am close to getting crazy.
I always use AdobeKULER for getting the values of RGB, CMYK and HEX for my logo designs made in AI.
Usually, i design a Logo in RGB first and convert it then as well into CMYK colors, using the values i get with KULER.
The CMYK color version of a design when viewed on my monitor normally look lighter (less dark) than the RGB version, but this time it is much darker.
I am trying to figure out where the problem is, but till yet i found no solution.
The RGB value in question is: 0 216 235
The CMYK value KULER shows is: 100 8 0 8
really hope, somebody can help me with this.
Thanks in advance,
Peter

Hey Peter,
Here are thoughts, so I created a new swatch in Illustrator CS5 with the RGB values of 0 216 235 in an RGB document and then converted that document to CMYK. The resulting CMYK values ended up being 61 0 13 0 versus the 100 8 0 8 which Kuler showed. So this tells me that the RGB conversions on the Kuler webpage use a different formula for doing the conversion versus what is done in Illustrator. Based on my experience, its not uncommon to see color shifts for colors which look slightly darker or washed out with this kind of conversion, because of the differences in gamuts between the two color spaces. For colors that fall outside of the gamut of one space, the closest equivilent in the other may vary based on the formula used. Different conversions aim for accuracy in different ways, closest match for tonal value, closest match for saturation, etc.
see sRGB versus CMYK in the following image
http://www.waleedsgallery.biz/_forumuploads/colorspaces.gif
I guess the question I would have for you is what are you doing with the logos you create, are they used for webpages, commercial printing or both? I would probably start with the color space related related to your output and be aware that shifts with conversions are expected. If you are printing these yourself on a home printer just working in RGB and letting the printer driver do the conversion often gives good results as the driver knows the specifics of that piece of hardware and its capabilities.
Hope that helps,
-Dave

Determining in and out Gamut values for RGB profiles

Hi all,
I am looking into how to check if a swatch value falls within my .icc profile gamut.
If I have a color value for example L=74 a=12 b=-37 and I want to see if it falls within my .icc profile I can select Edit>Convert to Profile and choose my profile
I then can select the swatch and see if there's a gamut warning there.
With the above swatch if my color profile is "Photoshop 5 Default CMYK" I will get the warning, if I change the profile to "US Newsprint (SNAP 2007)" I won't get it.
This works great for CMYK profile.
My question is how to check if the color falls inside an RGB profile?
I have tried changing the document intent to Web and Digital Publishing and changing the RGB profile but only changing the CMYK profile affects the out of gamut warning.
Does any one know of a solution to this? The same issue would appear to be in photoshop.
Thanks in advance.
Trevor

Timo,
actually he wants to set the attribute mapping dynamic, reading the field to map the return value to from a custom property.
1D10T,
If this could be done then in the Def object of a view object (which means its not per user session but use). Investigate into the View Object Def object for the view object that defines the list of value (not the one that you use as the LOV list source)

CMYK Values in InDesign different to Corel?

This is probably a stupid question, but..
I had to recreate a document in ID which had been created in Corel Draw, and the CMYK colour values don't seem to translate correctly.
For example, a colour in CD has 0,60,60,40 and 153,0,0 RGB. If I create a swatch in ID with 0,60,60,40, the red colur is way off compared to what I wanted - much lighter.
However, if I create a swatch with the RGB values (153,0,0), the colour looks pretty much correct. (Gamut issues aside.)
Can someone explain this?
Thanks.

Surely, a CMYK value is a CMYK value!
I'm not a corel draw user but a quick search for corel draw color management shows me that the most recent version includes a close imitation of Adobe's CM where a document can have an RGB and CMYK profile assigned which will drive the display of color:
www.corel.com/content/pdf/cdgsx5/Color_Management_Guide.pdf
In both cases the display of a CMYK value will be dependent on the CMYK profile you have assigned to the document (in ID default is US Web Coated SWOP). Try changing the CMYK assignment (Edit>Assign Profiles...) and the display of your CMYK colors will change. Same goes for RGB. Change the RGB assignment and your 153|0|0 RGB color will be displayed differently.
Rather than turning CM off, you could start by using the same profiles. Both applications have a default North American Prepress preset which roughly match each other:

I tried doing it with required="true immediate="true" but in my usecase the af:richTextEditor is in declarative component and can be called many times. I also tried with rendered but not sucessuful with my use case.
So i am looking for solution where i can have default value for af:richTextEditor, where if user entr nothing that default value (black space) is displayed.

public string getValue1(){
if(this.value1==null || this.value1.length == 0){
this.value1=" ";
return this.value1;
I tied this, which is good for my usecase. Bt it is still displaying null

Do you know of a way to adjust overall color using an existing CMYK value?

I'm attempting to match some color swatches as closely as possible. I don't have a color spectrometer so thought I'd try shooting and photograph of the swatches and adust them to values as close as possible to the actual. To do it, I included a Pantone Color Bridge book in the photograph, so I know the exact CMYK formula for one of the values in the photo. I'm wondering if there is a way of kind of reverse-engineering the image based on the value?
Thanks in advance.
