Crazy color conversion prodblem

I'm designing a package using PMS662. I color will be used in process. In PS when converted to process I get values of C:100 M:94 Y:31 K:13. In InDesign and Illustrator however I get values of C:100 M:71 Y:0 K:18. Now I know I can simply set the matching values in PS since this will printed in process, so this is more a curiosity thing that I'd like to better understand.
Some background - Color Settings are sync'd between apps and the color was selected from the same named Pantone book (Pantone Solid Coated) in all three apps. I've been doing this a long time and have never notice any other color be so different between programs.
Any insight would be appreciated. Thanks.

PS - I've attached a screen shot of the setting in PS for reference.

You are correct, from a color management standpoint Option 2 is much better. As long as you have the proper CMYK ICC you theoretically get the best match (which still oftentimes falls very short, i.e. Pantone 293)
The funny thing is that hardly anyone uses option 2. One reason I suspect is that ID an AI defaults to Solid to Process and no one changes the default setting.
Something else to consider. Pantone has in fact abandoned solid to process. The new books are Color Bridge. Some of the builds are very different. But again, hardly anyone uses Color Bridge because it's not the default behavior.
My honest opinion: try to avoid using Pantone Solid colors for CMYK designs. Many of the colors can't be matched anyway. I think the Pantone Process colors are a good option (the ones that start with DS). As long as your monitor is calibrated properly and you have an accurate CMYK ICC, when you select a Pantone Process swatch you can see a decent soft proof of the print color on-screen.

[AS][IDCS3] PDF Export Preferences Color Conversion setting

I want to set the field of Color Conversion (as equivalent to manual setting under Output>Color>Color Conversion) to "No Color Conversion" in Applescript but couldn't figure it out.
My skeleton Applescript is as follow:-
tell application "Adobe InDesign CS3"
   tell PDF export preferences
       -- I want to set No Color Conversion for Color Conversion here
   end tell
   tell document 1
       export format PDF type to filename without showing options
   end tell
end tell
I have search through Applescript ID CS3 dictionary but couldn't find the answer. Hope someone can advise. Thanks!

[AS][INDCC] How to set Color Conversion field to No Color Conversion when creating PDF Export preset

How can i set Color Conversion field in Export to PDF dialog to No Color Conversion when creating PDF Export preset? i have done a bit of searching and have found where it has been recommended to set effective pdf destination profile to use no profile but it doesn't seem to be producting the expected results.

Yes, it seems that i had to make the change after creation, not while creating the preset. thank you.
tell application "Adobe InDesign CC"
     set newPreset to make new PDF export preset with properties ¬

Open Illustrator and I get crazy colors all over

When I open Illustrator, I get crazy colors all over in my work environment (not all over the screen and not just on the art board but in the whole environment.) The colors are not always the same. Opening and closing the file doesn't solve the problem, I have to close the entire program. I can have multiple .ai files open, one might have crazy colors but the other doesn't. If I open Illustrator again and then the file, the problem doesn't necessarily happen again even with a file that was recently crazy.
A picture says a thousand words. Check out the attached capture.

From your email this does sounds like something random and sporadic that does not have a pattern. Has this started recently, or is this on a new machine. Has anything changed such as a font you did not use before, or an image or strange file format some of these file have. A corrupt/damaged image of something like a cmyk jpeg(the format was meant to be RGB and some programs occasionally act funny) can cause something like this.
Are you able to solve this by possibly toggling preview mode Command Y(Ctrl Y Win), view >> overprint preview. The preview almost looks like a cable is loose from your monitor to computer. Clean your computer with a can of compressed air and focus on any dust laying on the monitor card and cable connections outside the computer.
Sorry for all the wild guesses, but if you can tell us more about your system and any patterns you find, that can help.

CMYK to RGB color conversion?

Hi,
I have to convert CMYK color array in the RGB color space and vice versa.
I am using the following code;-
UID colorUID = iDrawing->GetColorUID(kFalse);
UIDRef colourUIDRef(iDrawing->GetDataBase(), colorUID);
InterfacePtr<IColorData> colorData(colourUIDRef, UseDefaultIID());
char
strColor[16]={0};
if(colorData->GetColorSpace() == kPMCsCalRGB)
    ColorArray rgbColor = Utils<IUIColorUtils>()->GetRGBColorValue(m_DB, colorUID);
    sprintf(strColor,
"#%.2x%.2x%.2x", ToInt32(rgbColor[0] * 255), ToInt32(rgbColor[1] * 255), ToInt32(rgbColor[2] * 255));
else
    ErrorCode errStatus = GetRGBColorStr(colourUIDRef, strColor);
ErrorCode GetRGBColorStr(UIDRef colourUIDRef,
char* strColor){
    ErrorCode status = kFailure;
    do
          I
nterfacePtr<IColorData> colorData(colourUIDRef, UseDefaultIID());          IDataBase* m_DB = colourUIDRef.GetDataBase();
// If color sapce is other then RGB then get the colour array
    ColorArray colourArray = colorData->GetColorData();
    // If the colour space is CMYK then convert it to RGB
    if(colorData->GetColorSpace() == ICMSProfile::kSourceTypeBuiltInCMYK)    {
          IDocument* document = Utils<ILayoutUIUtils>()->GetFrontDocument();
          ColorArray rgbColor = Utils<IColorSystemUtils>()->ColorTransform( document, colourArray, ICMSProfile::kSourceTypeBuiltInCMYK,ICMSProfile::kSourceTypeBuiltInRGB);
     sprintf(strColor,
"#%.2x%.2x%.2x", ToInt32(Round(rgbColor[0] * 255)), ToInt32(Round (rgbColor[1] * 255)), ToInt32(Round(rgbColor[2] * 255)));     status = kSuccess;
}while(kFalse);
return status;
}while(kFalse);
return status;

I did some experiments with Illustrator CS6 and the MacBeth RGB test chart and verified my results with Photoshop CS6. I discovered Illustrator is (mostly) doing what it should be doing, within a 1% error (probably rounding) on the output CMYK values. Here's a summary, in case anyone else needs this info:
Assuming the source file's elements are all untagged, when a mixed RGB/CMYK PDF is opened in Illustrator and CMYK mode is
chosen, Illustrator will use the profiles and rendering intent defined in
Color Settings to make the color conversions from RGB to CMYK. Thus, we
have control over the profiles used for this conversion.
If the RGB elements in the PDF file have embedded ICC profiles,
Illustrator will use the embedded ICC profile instead of the RGB profile
defined in Color Settings. This ONLY happens, however, if the PDF file
also includes the correct CMYK output intent profile.
If the PDF doesn't contain a CMYK output intent, Illustrator will fall
back on the Color Settings RGB profile for RGB->CMYK conversion. I believe it
would be more correct for Illustrator to use the embedded RGB profile and
the CMYK profile defined in Color Settings, but that's not how it seems to work.
If the PDF contains the incorrect CMYK output intent, Illustrator will
ignore the Color Settings and respect the embedded RGB and CMYK profiles
for the conversion, as might be expected.

ISight (iChat and PhotoBooth) cam is outputing CRAZY colors!

Hi Everyone!
I'm having an annoying issue. My HD recently crashed, and I just got it back from Apple. Fortunately I had TM running, so I got almost everything back. However.. after getting the machine up, and updating back to x.5.2.. my iSight is outputing CRAZY colors. Mainly yellow, grainy, nightvisiony looking image. It occurs in all video apps, I have tried resetting my SMC (although I have no way of knowing if I did or not), and jillions of restarts. I had this happen once before, and the SMC fix did it. Does anyone know a way to get the camera back to usable? Any thoughts would be GREATLY appreciated.

Hello Steve
... complete list of files (cache, library etc) that Isight draws upon.
I do not think that iSight uses ANY caches. I suppose the apps that operate your iSight might.
The best iSight technical info source I know is this search of the Apple Developer Connection. You may be able to get more specific help by becoming an ADC Member if you are not one already.
As an alternative to researching the ADC info, I offer another thought you may have already considered or tried. If I understand correctly what you have been doing at this thread in the Time Machine Forum, you believe that your iSight problem might be correctable by resetting preferences or clearing caches, but you have decided not to attempt resolution by deleting ALL system preferences and caches. If you think it might be beneficial, you could try an application like Yasu that can give you some control over which preferences and caches you can reset without using the terminal or deleting items generated and managed by OS X.
Finally, Steve, please allow me a word of caution for other readers. You seem to be an experienced OS X user who is more comfortable working at lower levels of OS X than many of us. For benefit of other readers who may be less knowledgeable, it is generally a bad idea to move, modify, rename, or delete any item outside your User > Documents folder unless you know what you are doing. While doing so will not harm your computer, if you damage your data or system files, you will need to restore them, which can be time consuming. Until you have enough knowledge to safely work with them manually, I suggest that you let OS X and your applications manage the files for you as they were designed to do.
Cheers,

IPhone showing crazy colors on screen when recording video?

I seem to be having a problem with my iPhone when I go to record video. I get this crazy colored looking screen (it shows up in the video and you can see it on screen when recording). Any ideas as to how to fix this?
Thanks in advance,
David

Hi David 14,
Thanks for using the Apple Support Communities. I understand that you are experiencing issues recording video on your iPhone. If you haven’t already done so, I would recommend forcing the camera application to close and restarting your device:
Get help with the camera on your iPhone, iPad, or iPod touch - Apple Support
https://support.apple.com/en-us/HT203040
2. Force the app to close, then open the Camera app again.
3. Restart your device, then open the Camera app again.

DNG & Camera Manf. JPG color conversions

IF, a Camera Manf. had a camera that outputs to DNG ... could they imbed in the DNG file ... the "equivelent" of LR "pre-sets" for "there" JPG Color conversion.
* So, In LR at a click of a Pre-set listing you could see what the Camera Manf. JPG out of the camera would be like. (if you "would have" shot this DNG in JPG) ... and then you could do a compair.
Or maybe you would "just" run it as a choice on import ... as a starting point, or when in a rush a result.
* Just curious ... could this be done?
Is it only me, or could this be a useful productivity feature for LR.
p.s. I do get the fact that you could make your own pre-sets for your camera.

> "being a designer/distributor myself you are always trying to find ways to make your product (output) different and exclusive ... so yes, having a Generic DNG and making "my" product/output a commodity would not be my first choice either".
I used to help design large, complicated, multi-supplier computer systems. I sometimes got involved with helping to procure products.
The suppliers would try to make us enthusiastic about their special features. If we procured their products, we would often simply lose those features under an abstraction layer of software - they were unwanted! We needed interchangeable components. Call it "commodity" if you like - but I don't really agree with that term here. "Commodity" to me implies that it doesn't matter which you choose. "Interchangeable" still leaves other factors to be taken into account.
If Nikon adopted DNG (chuckle!) we wouldn't really claim that a D40 and D80 and D200 and D2Xs were "commodity"! They would still be high quality high value differentiated products.
In fact, camera manufacturers are pretty foolish if they adopt such an attitude. Within weeks of camera launch, all the major raw converter suppliers have reverse-engineered the raw files and camera details enough to be able to perform high quality raw conversions. All essential aspects of the specification are known, and sometimes even published by 3rd parties!
Who do the camera manufacturers think they are hiding information from? Answer: "from 3rd party software companies whose mission is, in effect, to make the images from the camera look as good as possible"! How stupid can camera manufacturers be?
DNG still has ways for camera manufacturers to hold what Adobe call "secret sauce". There may well be limitations in the current specification of DNG that causes problems for some manufacturers - Hasselblad-Imacon apparently had problems. But most manufacturers almost certainly have no such problems - and Pentax shows what CAN be done by a camera manufacturer, (the one who once tried to promote the idea of a universal lens mount), that cares about its users and sees the way the world is moving.

Printing RGB colors - Conversion to CMYK?

Hi,
I have been working for a little while in converting my old RGB colors to CMYK printer friendly colors.
However, I carefully choosed my printing friendly CMYK colors to be as close as possible to the RGB colors but the prints are dull !
On the other hand, when I print my file withj RGB colors using the PDF Distiller tagged with Adobe1998 profile and send the file to the printer, colors look smarter !
It means that the CMYK colors I picked myself are not good enough anf the Color Managment in Adobe PDF or Illustrator are better than me ! As follows:
- In Illustrator -> Print -> Color Management tab -> Color Handling: Let Illustrator determine colors
- in Acrobat Reader -> Print -> Color Management tab of the plotter: Application managed colors
Both ouput similar quality prints, and better than my own CMYK colors !
Are the Application Color Management engines in Illustrator and in Adobe Reader similar in their conversion?
How can I find out which are the CMYK colors printed when the application (Reader or Illustrator) manages colors, from my initial RGB colors? I would like to use them directly in my document...
Thanks

Hi,
Thanks for your response. I put these color issues on hold because I had no time to search more on that recently...
However, I have still lots of questions about color conversion!
When I said "carefully choose" CMYK colors, it means CMYK colors printable and which look similar to my old RGB colors on-screen. But of course, screen is not enough!
What I noticed is that when I print my old RGB colors (not in printer color space), Adobe Reader or Illustrator were able to make good conversion to CMYK for printing.
Now, I would like to find out to which CMYK color codes Adobe Reader or Illustrator converted my RGB colors? Then, I would be able to use these CMYK color codes directly in my application...
Is there any way to find out that?
Cheers

Color conversion : special behavior with Spot Color "All"

Hello,
I have a document with printmarks which have a spot color "All". While I convert the page using the "Color conversion" to Gray 1.8 with Adobe Acrobat X the spot color "All" are still present (with the alternate color space DeviceGray).
Using Adobe Acrobat 9.x all objects have a DeviceGray color.
Is it a bug or a new behavior? Moreover the SDK method doesn't convert the spot color but keep the name (but I know this is not the right place to post it - it's just for information).
Regards,
Joe

I sense you may not understand the difference between sopt and process colors in the printing process.
When you use process inks you build all color representations by combining dots of varying sizes from each of the four process colors, cyan, magenta, yellow, and black. Because the dots are two small to be seen individually your brain is fooled into thinking it sees other colors. Process color printing requires four printing plates to produce the full range of colors possible, but that range is limited compared to what you can see in real life or capture in RGB.
Spot colors, in contrast, are similar to paint. Each color is mixed individually, and every spot color requires its own plate on the printing press (and you must use a press -- toner and inkjet printers use cmyk inksets and cannot print real spot colors). Because of the expense of these plates, the use of spot colors is usually limited to one or two colors in any print job, and if the job has other color (like photographs) that requires process inks, converting the spot colors to the closest process simulation is often employed if the spot colors can be simulated "close enough" to satisfy the client and the budget is tight.
I would avoid using process colors for type in small sizes or for very thin strokes, especially in lighter colors, as you are likely to see ragged edges.
So, how many spot color swatches did you use? More than two? More than four? Do you have a huge budget to produce the work? This may be a project that really should be designed from the ground up as process, or process and one spot for that hard to print bright accent color.

Disable color conversion when PDF export

how to disable color conversion in my sample scritp?
pdfExportPreset = app.pdfExportPresets.add({
name:"sample preset",
pdfExportPreset.standardsCompliance = PDFXStandards.PDFX1A2001_STANDARD;

actualy, if you need PDF-X1A standard, it's not as much about the export preset as is about the workflow. PDF/X-1a requires all fonts need to be embedded and all images need to be CMYK or spot colors. So if you have RGB images, they will be converted to obey the standard.

Crash while launching in "building color conversion tables"

Photoshop CS6 crashes while "building color conversion tables" I reinstalled the program but it still hangs up at this point. please help!

I've only seen 3 things that can cause a crash at that point: corrupt profiles (mostly display profiles), corrupt information coming from the OS about the system profiles, and bad floating point units in CPUs.
First thing to check is the display profiles. If setting them to sRGB doesn't solve the crash, it might be a bug in the OS profile cache. And let's hope it isn't the CPU, because those problems are a @$%^@#%# to track down in modern processors.

My iPad suddenly started to show crazy colors. I turned it off and had to use the two button trick to turn it back on. Now it shows only green stripes for a few seconds and goes back to sleep.

My iPad suddenly started to show crazy colors. I turned it off. It would not reboot until I used the two-button reboot. Now it shows only green stripes. only for a few seconds and goes back to sleep. HELP!

Standard troubleshooting...
1. Try a Restart by pressing the sleep/lock button until you see the slider. Slide to power off. Restart by pressing the sleep/lock button until you see the Apple logo.
2. Try a Reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider if, it comes up. Takes about 5-15 secs of button holding and you won't lose any data or settings.
3. Remove all apps from Recently Used list...
- From any Home Screen, double tap the home button to bring up the Recents List
- Tap and hold any icon in this list until they wiggle
- Press the red to delete all apps from this list.
- Press the home button twice when done.
4. If still a problem restore with your backup.
5. If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
6. If still a problem, it's likely a hardware issue.

Pantone Color Conversion

Have 2 Intel Mac Pros running 10.5.5, InDesign 5.0.4. When opening the same document on each machine I get 2 different CMYK color conversion of a Pantone color. Both machines have the same color settings as far as I can tell. Anyone have a idea why this happens, or how to make them the same.
Thanks

Choose the Ink Manager from the Swatches panel menu (or from Print dialog or Export PDF dialog). Look at the "Use Standard Lab Values for Spots" option at the bottom. Depending on whether on or off it will use Lab values (like Photoshop) or CMYK values (like ID and AI have traditionally used).
