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:

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,

CMYK values change between FH and Photoshop

Hi,
I'm trying to recreate a logo in FreeHand MX11 from one done
in Photoshop CS2 that's composed of PMS colors. Unfortunately, the
original artist didn't leave notes as to which PMS colors she used,
but when I sample a color in P'shop, I get a PMS color (286 PC
C100/M66/Y0/K2) that's a near match. Trouble is, when I assign that
same color in FreeHand, even though the color has the same CMYK
values, it looks much darker and not the same color at all. When I
copy and paste the image from FH into Photoshop and sample it, its
values change to C100/M86/Y23/K9.
I'm confused, how can both apps have so much variation in
displaying PMS colors? Is there a color management setting I need
to fix?
Thanks for any assistance,
Chris

The reason is most likely color management in FreeHand. Note
that there is a checkbox 'Color manage spot colors' in
Preferences/Colors. It should be checked, of course. Photoshop and
FreeHand use slightly different RGB color values for Pantone Spot
colors. The difference is very small, though.
Don't rely on screen color but check the colors from Patone
booklet because that's what the printer will do. Unlike cmyk colors
onscreen color management is not that crucial, although it is much
nicer to work if is set just right.
Also note that not single Pantone Spot color can be reprouced
with cmyk colors. Espeicially greens, orages and violets will
change significantly. Pantone Spot to CMYK chart is a very useful
tool, included in the 'Panton Survival Kit'.

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)

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!

tell application "Adobe Illustrator"

                    repeat with i from 1 to count of sw
                              set swname to name of item i of sw
                              if swname = "Dark Green" then
                                        set swco to color of item i of sw
                                        repeat with k from (count of theList) to 1 by -1
                                                  set co to fill color of item k of theList
                                                  if swco = co then

DataGridCellStyle: Set Background of DataGridCell based on value in a Different DataGrid / DataTable

Hi everyone
I am trying to set the background of a cell in a datagrid based on a value in a different datagrid. Is it possible to specify this in the XAML through binding? I'm using the MVVM pattern and would like to minimise code in the code behind. Please note that
the datagrids are the same dimension, but the dimension is unknown until runtime.
I've copied an image of the two datagrids. Essentially, the second datagrid will contain values of 0 or 1. I would then like to color the cells in the first datagrid a different color based on these values.
CODE:
<DataGrid Style="{StaticResource Style1}" ItemsSource="{Binding Table1, StringFormat=n}" AutoGenerateColumns="True" >
<DataGrid.InputBindings>
<MouseBinding MouseAction="LeftDoubleClick" Command="{Binding CommandWithParameter}" CommandParameter="{Binding .}"/>
</DataGrid.InputBindings>
<DataGrid.CellStyle>
<Style TargetType="DataGridCell">
<Setter Property="Background" Value="{Binding Table2, Converter={StaticResource WeightConverter} }"/>
</Style>
</DataGrid.CellStyle>
</DataGrid>
Thanks!

You could use a DataTrigger that binds to a column of a row of the other DataGrid like this:
<DataGrid x:Name="datagrid"></DataGrid>
<DataGrid x:Name="datagrid2">
<DataGrid.CellStyle>
<Style TargetType="DataGridCell">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=Items[0].num, ElementName=dataGrid}" Value="abc">
<Setter Property="Foreground" Value="Red"/>
</DataTrigger>
</Style.Triggers>
</Style>
</DataGrid.CellStyle>
</DataGrid>
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("num") { DataType = typeof(string) });
dt.Rows.Add("abc");
datagrid.ItemsSource = dt.DefaultView;
datagrid2.ItemsSource = new List<string> {"a", "b", "c" };
Hope that helps.

Will a sequence return same value for two different sessions?

Is there a possibility that a sequence will return same value to two different sessions when it is referred exactly at the same instance of time?

@Justin... Thanks for your insight; indeed, we too feel this shouldn't ever happen and never heard of it either, but there it is. (No, we haven't logged a TAR yet -- whatever that is -- partly because it didn't occur to us and partly because we only recently came across the issue and sensibly want to do some testing before we cry foul.)
However, the code is pretty straight-forward, much like this (inside a FOR EACH ROW trigger body):
SELECT <seqname>.NEXTVAL INTO <keyvar> FROM DUAL;
INSERT INTO <tblname> (<keyfield>, <... some other fields>)
VALUES(<keyvar>, <... some other values> );
(where <tblname> is NOT the table on which the trigger is fired). This is the only place where the sequence is ever accessed. The sequence state is way below its limits (either MAXVALUE or <keyfield>/<keyvar> datatype size).
In this setup, end users sometimes got an out-of-the-blue SQL error to the effect that uniqueness constraint has been violated -- as I said, we used to have a unique index on <keyfield> -- which leads us to assume that the sequence generated a duplicate key (only way for the constraint to be violated, AFAIK). We released the constraint and indeed, using a simple SELECT <keyfield>, COUNT(*) FROM <tblname> GROUP BY <keyfield> HAVING COUNT(*)>1 got us some results.
Unfortunately, the <tblname> table gets regularly purged by a consumer process so it's hard to trace; now we created a logger trigger, on <tblname> this time, which tracks cases of duplicate <keyfield> inserts... We'll see how it goes.
@Laurent... winks at the CYCLE thing Our sequence is (needless to say) declared as NOCYCLE and the datatype is large enough to hold MAXVALUE.

Why does Illustrator automatically change RGB and CMYK values

Hi, I am struggling to understand why Illustrator is changing the values inside the RGB and CMYK boxes. I am also not sure of the exact relationship between these values. Essentially, it appears that if you set the Document Color Mode to RGB, it leaves the RGB values that you type in alone. If you set the Document Color Mode to CMYK, it leaves the CMYK values alone.
But as soon as you change the Color Mode, it automatically modifies the values. So if you were in RGB mode and you set some RGB values, it changes those RGB values when you switch to CMYK mode. And vice versa.
I had thought that the CMYK palette was a subset of the RGB palette. It would make sense to me if it did this when I switched from RGB to CMYK mode, but it doesn't make sense to me why it does this when I switch from CMYK to RGB mode.
The other thing I am confused about is the relationship of the values in the RGB boxes to the values in the CMYK boxes. I would have thought that the relationship between them would be static. Actually, it is not. When I am in CMYK mode and I enter a CMYK value of 90 16 0 0, the RGB values become 0 158 222. But when I switch over to RGB mode, the RGB values of 0 158 222 result in CMYK values of 75 23 0 0.
Very confusing.
Thanks in advance if you can explain this behavior!

Color management.

Essentially, it appears that if you set the Document Color Mode to RGB, it leaves the RGB values that you type in alone. If you set the Document Color Mode to CMYK, it leaves the CMYK values alone.
An Ai document can be either RGB or CMYK. The colors follow the document color mode and thus are converted immediately if they don't match.
But as soon as you change the Color Mode, it automatically modifies the values. So if you were in RGB mode and you set some RGB values, it changes those RGB values when you switch to CMYK mode. And vice versa.
Same reason.

It's not. CMYK color spaces (there are more than just one) are normally smaller than RGB color spaces, but they aren't a "subset".
The other thing I am confused about is the relationship of the values in the RGB boxes to the values in the CMYK boxes. I would have thought that the relationship between them would be static. Actually, it is not. When I am in CMYK mode and I enter a CMYK value of 90 16 0 0, the RGB values become 0 158 222. But when I switch over to RGB mode, the RGB values of 0 158 222 result in CMYK values of 75 23 0 0.
When Illustrator converts the colors, it uses color management: the profiles you set up and the methods you set up. After converting it forgets the color that used to be. When converting "back", it uses color management again.
When you convert an very bright RGB color, it be out of the CMYK gamut. So it get's converted to the closest possbile CMYK color (which might still be far away from the original color. But it's not possible to convert it "back" to the bright one unless you just revert the conversion (by Cmd/Ctrl + Z).

Is it possible to sort dimension values in order different from alphabetic?

Is it possible to sort dimension values in order different from alphabetic. То use this sorting in BI Beans. In 10g r2 with awm 10.2.0.2. I try to add attribute like it was show in this forum, but nothing changes.

Could be usefull if you use java AW api... here's the java code I'm using to create the sort_order attribute
Dimension myDim = yourAW.findDimension("DIMNAME");
Attribute myAttr = myDim.createAttribute();
myAttr.setName("freename");
myAttr.setClassification("DEFAULT_ORDER");
myAttr.setIsDefaultOrder(true); // TO NOT FORGET
myAttr.setDataType("INTEGER");
myAttr.Create(AWConnection);
globalAW.Commit(AWConnection);
It creates a variable - integer - that defines the default order of the dim values. I'm viewing it with AWM and BIBeans. The order is respected with Level-based and Value-based hierarchy but my hierarchies are really simple and unique for all the dimensions.
BUT !!!! Be carefull, if you don't have any hierarchy in your dimension, you must have at least one level - the default NONE level. Otherwise, it won't work ???

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?

Comparing row values in two different tables

Hello,
Does anyone know if it is possible to compare (and possibly highlight - which I know can be done) row values in two different tables?
I have a ZIP Code column in table A that I want to compare to a ZIP Code column in table B and highlight those ZIP Codes that are present in table B but not in table A etc. Is this possible?
Thanks,
Kenneth

To be able to apply conditional formatting, I must edit the formulas this way.
=IF(ISBLANK(B)," ",IF(ISERROR(VLOOKUP(B,Tableau 2 :: B,1,0))," ",VLOOKUP(B,Tableau 2 :: B,1,0)))
=IF(ISBLANK(B)," ",IF(ISERROR(VLOOKUP(B,Tableau 1 :: B,1,0))," ",VLOOKUP(B,Tableau 1 :: B,1,0)))
I replaces the four empty strings by strings containing one space character.
In the field supposed to contain the text which is not contained I just entered a single space character.

Selecting by CMYK value or Swatch Name

I am new at scripting so please forgive me. What I want my script to do is look in an open document for any items that are colored a certain swatch color or CMYK value.
I do have named swatches. For instance "032 (Red)". This swatch is a PANTONE swatch. The other CMYK values I need to search for are C:0, M:98, Y:82, K:0. What I would like the script to do is search the document for any items that have those CMYK values OR that swatch "032 (Red)" applied to it and then apply the "032 (Red)" swatch to it and then set the stroke properties to a line weight of 1.6, then a round join, and a dash of 6,4,6,4,30,4.
I know this may be asking a lot...and I am sorry that I don't even have a script to start with and edit. But being so new...I don't know where to start. I have the scripting guide but if someone could get me going on this I think I could make some headway.
Much appreciated!

Why two FLOAT values are stored differently?

Curious as to why two FLOAT values are stored differently. Inserting
two FLOAT values one with value of 99E9 and the other with 12E-9.
Value for 99E9 was stored in the database as 99000000000 and 12E-9
was stored in the database as 1.2E-8. Why were they stored in
different formats? I am using Oracle9i
