Black color slider is multi colored. Glitch?

My black color slider is stuck as a multicolored gradient. The file was originally in RGB mode and I've seen it happen before but usually if I change my color mode to CMYK the black slider bar goes back to normal.
Does anyone know any way to fix this with illustrator open? It doesn't go away unless I close and re-open illustrator. I don't think that it affects my output colors...it's more just annoying.

Yes, that's a known bug in some Illustrator versions.

PDF creation causes rich black colors to shift

I'm designing a book cover. There are three main areas: front, back and spine. Each area has specified the default "black" color in the swatches panel. This color uses 100% K in the CMYK color space. In the preferences panel, under "appearance of black", I have checked to print and display blacks as rich black. Everthing looks great on the Indesign file. My blacks are as specified. Everything has been double-checked on the swatch panel to be set to this black color, which is a non-editable color (always remains 100% K on the CMYK setting).It has been displaying just fine on the file, as a rich black, no color shifting ever whatsoever until doing the following:
When I make a PDF using the "Export" window, I select PDF/x-1A as my printer specifies. I create the PDF, and open it, only to see that my blacks are being shifted to a shade of deep brownish black.
On the first few attempts, only two of the three areas specified above did this. ON the next attempts, all three areas look the same. This is weird. I'm very disappointed with the strange issues present in Indesign, as I am trained with Quarkxpress and find it to work flawlessly in comparison, especially with something like color output.
What am I doing wrong?
When I change settings, for example, change the color management to "none" or leave it in the default for the PDFx/1-a, it doesn't make any difference in this glitch in the output.
Help!
Thanks.

The Appearance of Black setting to print all blacks as rich black ONLY affects printing or exporting to RGB devices (essentially printing to desktop printers or PRINTING to PDF with Composite RGB or Composite Grayscale selected). It has no effect at all on EXPORT to PDF.
>I changed my 100%K only blacks to genuine rich blacks of 100%K 25%C 25%Y 25%M and the problem is corrected.
You said this is a book cover. That implies that the output will be printed, not viewed on screen. For printed output it is ESSENTIAL that you set blacks to display accurately. You should also turn on Overprint Preview when judging color. You'll probably get away with your rich black in any type over 12 points or so where it might be applied, but it's generally not a great idea to use rich black for type in small sizes. Rich blacks also generally use slightly more cyan than yellow and magenta to compensate for ink impurities.
Do you have a high-end monitor? Is your monitor calibrated and profiled using a colorimeter? If not, you can forget what you see on screen. The odds that it is anywhere near accurate are similar to the odds of winning the lottery. Are you using the same color space in Acrobat as you are in ID? If you change the color space, the appearance of your colors will change.
When you export to PDF/X-1a you are converting everything to CMYK using a target color space. By default the conversion option is set to preserve numbers. If your imported art has an embedded profile that differs from the destination, that will be honored and color numbers will be changed to preserve the appearance of color, as much as possible taking into account different gamuts, and untagged imported art, along with native objects will all be presumed to be in the current working space in ID, and cmyk numbers for those objects will be preserved. If the destination space differs from the working space, thew appearance of these colors will shift, but 100% K native objects will continue to be 100% K in the PDF. A conversion to a destination that differs from the working space WITHOUT preserving numbers will result in 100% K being changed to a 4-color mix that mimics the appearance of 100% K output in the working space.
Knowing the destination space in advance is vital if you are doing a CMYK conversion. CMYK profiles are "device dependent" and CMYK-to-CMYK conversions are destructive, both in terms of potential loss of color (and you don't gain by going from a smaller to a larger gamut space) and conversion of solid colors to 4-color mixes which is particularly problematic for black type and thin rules.

Creation of PDF from Excel 2013 - problem with black color

Hi,
I am a publisher of crossword magazine and I use Excel to write crosswords. Then I create PDF's and import them into InDesign.
In past I used Adobe printer and it works fine with Excel 2000 and 2010 (only these two versions I used in past) Now I switched to Excel 2013 and when I use Adobe printer to print crosswords into PDF problem occurs with lines done in Excel (insert - shapes - line). I use black color for these lines but in PDF they appears as rich black (TIC 300%). Why it is not 100% black? I know that Excel works in RGB but in past I was always able to change settings in printer profiles (Adobe printer) to reach 100 % black without CMY colors. Now I have no idea. I attached picture of pdf how it looks in Adobe Acrobat in Outpur preview.
Thank you in advance for any advice

These are tough issues I suspect and the answer you need is probably trivial (it is finding it). I will make some suggestions, but I have no idea if any will work.
- In the printer under the Properties>Layout>Advanced>print quality, I use 300 dpi (default is 1200).
- Under the printer preferences>settings>edit the settings file, I use again 300 dpi (default is 1200 dpi).
These may not fix your issue, but migth be worth a try. You could also try using the preflight script to change to gray-scale. It may not make any changes, but again may be worth a try.
All I am trying to suggest are the things I would be looking at. Maybe they will lead you someplace. Others may be by with better suggestions in time.

Preserving Black color values when converting color PDF to grayscale

I opened a full colored PDF document (exported from InDesign using Profile: Euroscale Coated v2) in Photoshop and tried to convert it to grayscale (image > mode > grayscale) and noticed that the black color values changed. text for example that was 100% black in the PDF document became a screen of 91% black.
is there a way to preserve color values when converting full color PDF documents to grayscale?
or in other words WHICH is the correct way to convert full color PDF documents or full color InDesign files to grayscale?
I am using Adobe CS 3, Acrobat 8 Professional, on Mac OS 10.5.5

Before you open the PDF in Photoshop, set PS's Color Settings to Photoshop 5 Default Spaces. When you open the PDF set the Mode to Grayscale in the Import dialog. Just remember to reset your color settings when you're done.
Edit: Also, if you want to match black percentages as well as 100% black, set the Photoshop Color Settings to Photoshop 5 Default Spaces with the Gray working space to Dot Gain 20%.

InDesign CS3 - Default Black color issue

Default Black color converted as Spot color in Indesign CS3.
I'm using default color "Black" in InDesign CS3. While creating PS from InDesign CS3 and convert it as PDF using Distiller 7 & 8, it would have changed as "Spot Color Black" instead of color "Black(CMYK)".
Open the swatch and duplicate the color "Black" and renamed as "C=0,M=0,Y=0,K=100". It would work properly. i.e. output PDF has CYMK black instead of Spot color.
We are unable to find/change globally because the Default color [Black] has both text and object.
We do not have any problem with this default black color in Indesign CS2.
It would be better if you provide a solid solution for this issue immediately. I need to send a test file to the printer on tomorrow (05/27/09).
I have attached Testing.pdf and screenshot for your reference.
Picture 1 shows the Default Black color converted as Spot color.
Picture 2 shows duplicate black color created from Default [Black] color and we don't find any issue.
Thanks
Johnson

First, this is a user forum, so all you'll get here is advice, not a "solid solution" from Adobe.
Second, the current versions of InDesign and Acrobat are 6 and 9, respectively, and there will never be any new patches issued for earlier versions. Adobe does not divert effort away from current development to patch old software.
This has been discussed here in the past few months. You should be able to find the thread if you search for keywords like spot black. For what it's worth, Acrobat 9 Pro's preflight does not detect a spot black in your sample PDF (though Pitstop might).
I'm curious why you feel the need to distill PDF rather than export (as I see you did with the file you posted)?

Black color link change to something else

How can I replace the black link to some other link color from the process chains between the Start and the Load data objects? When I use the black links, I would get an error message to say that there are too many processes and not enough background processes: "Too many parallel processes for chosen server".
Can the blank color links be used between the Start and the Load Data objects? I have about 5 to 6 Data Load objects to connect between.

Hi,
The Link connecting Start Process and subsequent Load process will always be Black.
The Other Link colors defines as per the following
Green
A link is displayed in green if the event is triggered after the process that precedes it has been completed successfully.
Red
A link is displayed in red if the event is to be triggered when the process that precedes it has been completed with errors.
Gray(link with Both Red and Green Circles)
A link is displayed gray if the event is to be triggered after the process that precedes it was successful or not. When such a link originates from a process, only such links can originate from this process. Refer also here to Documentation for Possible Links.
Black
A link is displayed black when the event is triggered after the preceding process was completed and the system cannot tell whether the process was successful or not.
<b>You can change the Color by removing the Link(right click on link and remove) and again while connecting you will get all the Three Options(green, red, Grey(red and green) Except Black color)</b>
Hope this helps,
Sudhakar.

Only scanned document (jpeg) can print black color

Hello everyone,
I have a weird problem with my printer. Black ink is not printing properly. Whenever I print any .doc or text files, a blurry page comes out..and sometimes, i got nothing but an empty page. What makes it weird is, I can print any scanned doc saved as jpeg with no problem. Black color gets printed with photos.
I already used the maintenance tools like cleaning and aligning the ink cartridge but to no avail. The ink level is also full.
Any idea what's happening?

OK, I checked the versions of the different machines running IE and they are all 5.00.2614.3500. Also, for the time being, my policy file consists of:
grant {
// Allow everything for now
permission java.security.AllPermission;
};What other security issues to I need to investigate? Thanks so much for your responses!

Rich Black Color in AI CS3

Hi, everyone!
I am using AI CS3. I want to apply the rich black color to my name card as below. Please let me know whether it's good to apply a rich black color in this condition. If so, please tell me how to make it as a rich black color for CMYK Process ( C=? ; M=? ; Y=? ; K=? ).
Everyone helps me! I will be very pleased and surprised to get the fastest answer.
Luck

Are you printing digitally in colour? If not, then there is little reason to use a rich black. On an offset press you can use a custom black to get a very dark and saturated result.
If you’re still here, then I guess it’s four colour digital. I would use 40, 30, 30, 100 for by black. I would also add a process black only (0, 0, 0, 100) keepaway around the type. Select the text objects and go to the Appearance panel. Click on Add New Stroke and drag the stroke below the Characters line. Make the stroke 1 point (half will be hidden under the text) black (0, 0, 0, 100). Use Separation Preview to verify that the black stroke does not overprint. Do the same in Acrobat Pro using Advanced > Print Production > Output Preview.
Appearance panel…
Separation Preview with all colours…
Separation Preview with black off…
(See that the text looks bolder? That’s what you want.)

Illustrator cs6 white and black color changed to "blanco and negro"?

I created a "user defined swatch" and it was working fine until today I opened my file and wanted to update the file and then I realized the white and black color on the swatch changed! The white is still 0,0,0,0 but the black changed to c=71.39%, m=65.35%, y=66.87%, k= 76.71%. Not just that, the red changed to "Rojo CMYK" and the yellow changed to "Amarillo CMYK".
May I know how to change it back to normal black, white, red, etc...? Thanks!

No. Never in spanish. I've been using this Illustrator and this "user defined swatch" for so long and never in spanish. And my system is in English too...coz I don't know any spanish.
What changed is that...in my "user defined swatch", the black value from c=0, m=0, y=0, k= 100 to c=71.39%, m=65.35%, y=66.87%, k= 76.71% and the name is not "BLACK" but "negro". The white is still c=0, m=0, y=0, k= 0, but when you hover, you will see the color is not called "white" but changes to "blanco". All the gray color is not 80%, 70%, 10%...any more. All the cmyk number changed. All the gradient names too.
I am sorry that I couldn't provide any screen shot coz yesterday I already deleted my own swatch and create a new one...which has no problem.

Photoshop document is black color

Hello,
I installedadobe photoshop CS4, installation went fine, I started the photoshop, I pressed CTRL + N, i'm getting new document with black color even if my background color is white. I select some other foreground color and painten on the back document, nothing to see, when I hold down the mouse and moving the tab I can see what i just paint, when I release the mouse its balck again. What I am going wrong? how can I solve this? pls. can someone help. Its also same if I open a photo, its black, when moving I can see the photo
thx

Photoshop doesn't have a color profile: your documents have profiles, and your display has a profile. Your display profile is the one that would affect all images.
If images display all black, the most likely problem is your display driver. Turning off OpenGL drawing may help (to at least identify the cause and let you get some work done). Updating the driver

'Pantone Black' (color bridge uncoated / plus series) doesn't 'look on screen' as black at all.

I'm working in Adobe Illustrator CC on a mac.
'Pantone Black' (color bridge uncouted / plus series) doesn't 'look on screen' as black at all. A '100%K' black (cmyk) look perfectly black. The Pantone solid black appears nothing like a 'black' at all on screen. Is there a setting that makes the colors 'look' more like the end result?
Also is there a reason, a lot of the colors in the 'Color Bridge Uncoated - Plus Series' doesn't come up in the Adobe Illustrator 'Color Bridge Uncoated' pallette?
Can anybody help me out?

What does the Pantone Black Uncoated Plus Series look like? I mean, on your screen? Is it brownish? Not sure why Pantone Bridge does not show in Illustrator Bridge. The entire color communications system(s) seemed to be a bit messed up. There seems to be a drift on screen when looking at Pantone anything these days.

Rotate Operator leaves black color around destination image

Hi Everyone,
I am creating a JPeg image which has two layers. First one is the background image layer. Second one is the photo which i want to put on the center on the back ground image. I am using overlay operator for this purpose.I have already done this thing.. BUT when i try to rotate the photo then a black color appears (in the area where part of un-rotated image was). I want the background image to be there instead of that black colour..
I have searched a lot but did not find the solution.. Please help.
Thanks & Best Regards,
Masood Ahmad

Hi,
It works perfect.. i am doing the same thing using rotate operator in JAI... why that is not working... I am pasting both Rotate programs here.. One is in Java2D and 2nd in JAI.. Java2D is working but JAI rotate is leaving black area after rotation.
Please tell where i am wrong in JAI or is it bug in JAI?

Exporting PSD to JPG/TIFF generate a distorted black color

Hello,
I use Photoshop CC 2014.1 on OSX Maverick.
When I export a layered PSD to JPG/TIFF I obtain an image with a distorted black color. The image has multiple layers, two of which are the photo I took (with black background) and an added black background.
In Photoshop there is no difference between the 2 background (they have the same black colour), but the result of the exporting is the attached picture.
Could you please help me in solving the problem? How can export the PSD image correctly?
Thanks.
Andrea

Even if I flatten the psd there is the same difference
Then the difference is in the layered psd even if it many not be displayed in the layered state – is it visible at View > 100%?
Could you post a screenshot of the border region taken at View > 100%?
Noise in the photograph may be a factor.
I think you should apply a Layer Mask to the photographic element to make sure the background is uniform (the added black background).

Black color slider is multi colored. Glitch?
