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.

Calculating based on a previous value when initial column values differ from the rest

Let me preface this by saying I am new to the BO world. I'm trying to build a report/chart that tracks incoming loads. The first supply on hand value is pulled from the database and each successive supply on hand is based on the previous row's values.
In the supply arriving column below, the iniital value differs from the rest using the formula:
=If [Row Number]=1 Then [First Supply Arriving] Else [Supply Arriving]
The supply on hand uses the same idea, but is where I'm running into problems. The first column value should be [Supply On Hand], easy enough. Each successive column value needs to follow this equation:
Previous([Supply On Hand] (this won't always be [Supply On Hand] though, only for the second row essentially - problem 1) + Previous([Supply Arriving] (same as problem 1, where this is first supple arriving for the second row and then supply arriving moving forward) - [Usage Rate]
If someone could help me in getting the calculation to pull the previous values correctly without making a ton of variables, I'd greatly appreciate it. We just upgraded to 4.1

Yes, the supply on hand and the supply arriving from the previous row need added together. The usage rate, which is a constant is then subtracted from that. The result is the on hand total for the next day.
For example:
Date
On Hand
Arriving
Usage Rate
9/9/2014
100,000

Help! White line outlining image only in CMYK when placed from Photoshop into Illustrator/InDesign

I have a CMYK file, outlined product, that looks perfect in Photoshop. When I place the image into Illustrator, it shows up with a thin white line around parts of the product (fyi - it shows up on a print as well). I have tried to place an RGB file and it does not have the white line around the product. I assume it has something to do with it being CMYK, but I'm at a loss on how to fix this. I'm desperate for any help.

Okay, please refer this image and change the option within Ai General preferences. Uncheck the option Anti-Aliased artwork.

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'.

Determine closest PMS color from CMYK values?

In Illustrator CS3 is there a way to determine CMYK values to the closest PMS color? I know how to do it in Photoshop but cannot find a solution in Illy Forums, Illy Help, or from any intelligent person I might happen to know.
Thanks to anyone!

I use un script to know what PMS values is closet to a certain CMYK,
on the other way, what CMYK is close to certain PMS, just doble click on the PMS on the swatches palete and convert it to CMYK process..
A quick way to do it, may be there is some more technical method out there..
If you wish, here you can download the script wich is not mine, dont remember the author...sorry.

Cannot enter a decimal cmyk value in photoshop? Is rounding it up acurate?

I know it's a stupid question but in illustrator I can add in a decimal....in photoshop I am told that I cannot.
Why is this?
Thanks in advance.

In CS4, Illy will show decimals, Indesign and Photoshop will round up and not show the post-decimal values.
In Photoshop (CMYK mode), you can have more than one step within 1% (according to info panel) presumably 100% divided evenly into 255 steps and I can see 3 distinct levels between 0 and 1% dot (per channel).
These will often be a problem if you let them sneak in unexpectedly, so best to round off the .xx figures in Illustrator. I don't know why Illustrator has had this option, seems a bit pointless to me and introduces a significant risk for printers and designers for no real gain.
That's not to say there is no need for all 255 steps, I am not saying that, only that they are dangerous as 'selectable' values and should only be there for use in smooth blends and feathers etc.
I presume this is why Photoshop doesn't let you pick on a % slider, it would jump along unevenly 0 then .392 .784 etc whereas the rgb slider can happily count from 0 to 255. The available tones are based on each channel being 255 steps in 8 bit per channel files.

InDesign seeing spot channel color from Photoshop as a lab value

Does anyone know why Indesign sees a spot color that is created in Photoshop as a lab value rather then a cmyk value? FYI - I'm using CS4 6.0.5 and not planning on switching to 5 for a while and also on a Mac - using Leapord 10.5.8, and about to switch to SnowLeapord.
Anyways, If I place a Photoshop tiff into Indesign the spot color shows in the swatches as a lab value, and in Illustrator it is a CMYK value?
I can get it to see the color as CMYK in Indesign if I use a color library swatch from Photoshop, but no other way.
I'm using the color swatch for a RIP that uses that channel to print White ink, and sometimes it's useful to create the channel in Photoshop, the RIP sees the channel by a certain spot color designation. The spot color needs to be named in a particular way in order for proper work flow, so it's not desirable to have the swatch named a Pantone color.
Any ideas?
Thanks

You can take a custom spot colour and rename it to whatever you like in photoshop, when I import the graphic into InDesign CS4 I see the swatch as Lab spot (all Pantone Solid spots are defined as Lab, cmyk values are only determined by an app' that is asked to convert)
and when placed into Illustrator CS4 I see the same and if I double click on the spot swatch (still with the custom name I gave it in photoshop), I have a choice of Lab, cmyk etc at that time.
Indesign will correctly see the swatch as Lab until you request the app' to convert to cmyk at output or double click on the swatch and change it to cmyk.
You don't want the swatch to be cmyk, if you do that it will output as cmyk... if you want it to separate at the rip it needs to be a spot, which is seen by default as Lab in any application or can be converted to cmyk on request. You can't have it as a cmyk spot, that does not make sense unless you are outputting as only cmyk.

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!

Getting my indesign files to look what I'm out putting from Photoshop

Has anyone printed Blurb books using Indesign. There is supposedly this PDF work flow for Blurb books when using Indesign for Blurb books. Yet the printers that Blurb uses are best suited for SRGB like most labs..
Blurb strongly recommend one convert their files to CMYK when using Indesign.
I'm trying to figure out why in photoshop my files which will have great color and contrast and I'm using the custom proof setting in Photoshop for the Blurb ICC profile which is CMYK. Yet same color
file inside of Indesign will look different. Help
I'm getting to the point of looking at the rgb color values of my files in the information menu in Photoshop. So once i get my files back where I might have remove a certain amount of red from the file.
The blurb book may come back with the image being too red for my liking which is why I will remove some red from my fils. If I remove a certain amount of red out of the file only to receive a Blurb book where the file
comes back looking a bit too yellow. I need a more consistent way of judging my colors for this Blurb PDF workflow for using Indesign CS5.5 Plus you can get a proofs from Blurb and there isn't any comparison ink jet paperto use
on a ink jet printer to smilar the output for the blurb books
Blurb uses HP pritnters to print their digital book. Help.

Looking at Blurb's printing specs they recommend sending sRGB not CMYK:
http://www.blurb.com/educators/pdf/Blurb-Photographer-FAQ-02-18-09.pdf
They do offer a CMYK profile for soft proofing probably so users see RGB color in some CMYK gamut. I think most online printers do not allow CMYK to be output unchanged particularly if they offer uncoated printing—where unchecked total ink would be an obvious problem in an automated offset process.
Blurb offers one CMYK profile (looks like they've simply renamed Coated GRACoL) even though they print on a variety of coated and uncoated sheets, so even if you converted everything to CMYK using the provided profile, it is unlikely that those CMYK values would get printed—Coated GRACol would not work for Mohawk Superfine.
Since it's likely that all color will get converted on their end, providing the recommended sRGB and avoiding extra conversions is the best bet.

Help with imported eps files from photoshop and illustrator using PANTONE

I am new to InDesign and running into some very frustrating issues. I am preparing a catalogue for print which was created in Quark XPress previously. I tried converting it initially but had all kinds of strange things happening with type re-wrapping. The printer advised to recreate in InDesign. FIne by me because I'll learn as I go along.
So I created a page in InDesign and place and eps file created in Illustrator using a spot Pantone color and a halftone created in Photoshop also using the same spot Pantone color. In InDesign the color swatch menu show both colors one as 228 C and the other as 228 C 1. How do I get just one definition for PMS228 coated that works across all three programs? Stuff like this pisses me off. Adobe should have one definition across all three.
Help!!!

My best guess for the two definitions is that the CMYK values of the colours do not match, so InDesign treats them separately. You can merge them using the In Manager. Open the Swatches panel and select Ink Manager from the flyout menu. Select PANTONE 228C 1, go to the Ink Alais pop-up menu, and select PANTONE 228. Now InDesign will treat the two colours as one separation on output.
You should also take the time to open each graphic and resave as a native file. This means .psd for Photoshop and .ai for Illustrator. While there, see if you can make sure the colour names and definitions are consistent.

[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

of
it
repeat

from 1
to

if

of theList = {
class:

then

end

end
repeat
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.

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)

Grab colour from photoshop

If I have a mockup in photoshop the quickest way I know of to grab colour values is to eyedrop in photoshop look at the CMYK values for that colour and type them into indesign. I was just doing this for the nth time when I realised how stupid it was - surely theres a better way?

If you want the exact colors add them to your swatches in Photoshop and the from the swatches panel menu choose Save Swatches for Exchange.
The eyedropper does return an exact color—it's easy enough to test:
Make a CMYK psd file and fill it with any color. Save the file without a profile. Place the file in ID, draw a box on top of it and fill the top box with the psd color via the eyedropper. Export to PDFX/1-a. Open the PDF in Acrobat and the top box will be a seamless match to the bottom box.
Also, it doesn't matter what the display performance mode is when you pick up the color (including fast where there's no preview), which shows that the eyedropper is getting the value from the file itself and not the preview.
