100K Black and Rich Black problem

When I create something in AI and save it as PDF document, all Blacks in AI
I see as Rich Black, but when I open this pdf in Acrobat8, all blacks are
displayed as 100K Blacks..
Why this is happening?
I'm usign AI CS3 and Acrobat 8.
Preferences in AI:
On Screen: Display All Blacks as Rich Black
Printing/Exporting: Output All Blacks as Rich Black
Thanks in advance,
Roman

The preferences of "Printing/Exporting: Output All Blacks as Rich Black" is applicable only for printing to RGB printers like the desktop non-postscript printers or when exporting to RGB file formats.
When you save as PDF with [Illustrator Default] preset, you actually create a CMYK PDF. Acrobat has no such "Rich Black/Accurate Black" preference and hence displays "light" black.
If you create an RGB PDF by selecting Convert to Destination and Destination as an RGB profile,say, sRGB from the Output panel of Save Adobe PDF dialog, Acrobat should display your desired jet black.

Semi-transparent block, pure black and rich black problems

Hi!
I'm new to inDesign, and I'm currently designing a book cover, for which I need some special effects. I'll try to explain as best as I can.
The background is rich black, on top of it I have a text in white (all over it). I applied a block with 80% opacity, in rich black color. I cut out some shapes in it. The point was to have the text in dark gray all over the book cover, but in white in the places where I have the shapes.
Everything is working exactly like I want, but a friend of mine told me if I apply rich black over white, I'll get a kind of magenta gray, so I have to apply pure 100 K to avoid that and get the dark gray I want. I tried that, and of course, applying some pure black block on top of my rich black cover gives all the cover a "grayish black" look. How can I work around that? I tried setting my semi-transparent block to "darken", but it didn't change anything.
I put the links to the pdf, I hope that's ok.
That's the one with rich black: https://dl.dropboxusercontent.com/u/68049919/coverlayout_print_richblack.pdf
and that's how it looks with the pure black: https://dl.dropboxusercontent.com/u/68049919/coverlayout_print.pdf
Thanks a lot!

There's no need to use transparency to create your background text color—just make a text frame filled with the rich black then select the type and fill it with an 80% tint of the rich black swatch or any other gray mix. Like this:
The text frame selected with its fill showing in the Colors panel:
Here the text is selected and the Colors panel shows the text fill as an 80% tint of the rich black. There's no transparency in this case.
In general it's bad practice to use transparency when you can get the same effect with color fills.
Also if you are worried about the neutrality of the gray check with your printer on whether the gray text should be 4-color (your 80% tint) or straight black (95% black).
The accuracy of the InDesign softproof depends on an accurate monitor profile and the assigned CMYK profile (Edit>Assign Profiles...). The assigned CMYK profile affects the preview including the profiled gray balance. For example the default SWOP CMYK profile previews your 4-color dark gray bluer and as a lighter value than US Sheetfed.

Importing PS tranparencies and Rich Black

Hi
Im having a problem importing photoshop files containing transparent backgrounds.
Evertime I place one on a black background and publish ,the background appears dark grey
Output all blacks as rich blacks is defined
and my PDF present is Press quailty
Indesign cs3
Any help would be GREATLY appreciated!

The user has sent me the files, and her settings, and I think I've finally found the problem.
You are printing to PDF, which is OK, but exporting is simpler, and less prone, I think, to problems. I was finally able to reproduce the rich black by printing to PDF and using the "standard" joboptions in the printer properties (though it wouldn't be limited to just that particular option set). Those options do an internal conversion to RGB, which is then getting converted back to rich black.
Make sure you click the setup button in the print dialog to access the printer driver, then change the default settings to something that either converts to CMYK or preserves color, and you should be fine, or export and set the color in the export dialog.

PLEASE HELP I am using an alienware m11x and the only problem i have is when i go to the bar on firefox 4 like the file,edit,etcc what every my mouse hovers over turns black and stays black :/

When my mouse hovers over the bar on firefox 4 it turns black so if i hover all of them all of them turn black and stay black and i cant see anything. Also I am using an alienware m11x with a dual core duo 2 Su700 (@1.3) (@1.3) with a 1g nvadia graphics card 335m geforce.

Make sure that you allow pages to choose their colors and that you haven't enabled High Contrast in the Accessibility settings.

Exporting CYMK Black as Rich Black

I continue to struggle with getting CYMK Black as rich black. I have Illustrator CS4.....
Settings that seem relevant follow:
The Document Color Mode is set to CYMK
The Appearance of Black is set to both display and export as Rich Black
When I do an export to JPG or Print to Adobe PDF driver, the black come out as dark gray
The object color appear correct 0,0,0,100
The black displays as rich black when I am working on it in illustrator
What am I missing here..... The way I work around it to send a proof to a customer is change the doc color mode to RGB.....but that really only is suitable for all black art......and it's seems to be a cludgy work around.
I guess the question is why isn't illustrator CS4 outputing rich black when I set ouput as rich black for export?
I have read other posts here on the subject but they seem to be work arounds as well.
Is there something I am missing here fundementally?? Perhaps another setting I am unaware of?
Thanks!

Rich Black is more like 100% Black 60% C 60% M and 60% Y there are all types of combinations printers use.
What you should do is to make swatches of your various rich blacks after discussing it with your printers as to their preferences and your needs and name them to correspond to the printer (vender) and then save it as a rich black library that way you won't even have thin about it in the future.

Critical Irish Update needed to solve black and white tv problem on G20!

I recently had trouble with setting up tv on my Qosmio G20, I was pointed in the direction of a black and white problem that affects earlier models. The solution to the problem was to use the g20's drivers and run 2 reg files.
Having done that to no success i tried every irish combination possible, with still black and white, I then tried UK and got colour.
I mucked about with the registration files and found that in the file, there was no irish setting, So when a user puts ireland in as their location they will always get black and white.
Ireland uses the exact same settings for tv as the UK does, However if a person choses UK they will not get irish guides or irish channels to pick from (ireland isnt part of the uk)
i found the settings for the UK -
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\ttv200x\Parameters\44]
@="United Kingdom"
"FreqBoundary"=dword:000493e0
"LB_VideoStandard"=dword:20000080
"LB_AudioStandard"=dword:00020000
"LB_ShiftFreq"=dword:00000abe
"HB_VideoStandard"=dword:20000080
"HB_AudioStandard"=dword:00020000
"HB_ShiftFreq"=dword:00000abe
Figuring the 44, was the dial code for UK (that took a while to figure) i added a registry entry with exactly the same settings, but with ireland and 353 at the top.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\ttv200x\Parameters\353]
@="Ireland"
"FreqBoundary"=dword:000493e0
"LB_VideoStandard"=dword:20000080
"LB_AudioStandard"=dword:00020000
"LB_ShiftFreq"=dword:00000abe
"HB_VideoStandard"=dword:20000080
"HB_AudioStandard"=dword:00020000
"HB_ShiftFreq"=dword:00000abe
I now have colour tv under the irish settings in media centre, i also have sound now, where before i didnt. Hopefully the above code will be added to the registry file named ttv2_regdata_20050111.reg that comes as part of the http://support.toshiba-tro.de/kb0/TSB5800V20000R01.htm driver fix for the problem..
thanks to jimi in the following post http://forums.computers.toshiba-europe.com/forums/thread.jspa?forumID=42&threadID=11145 for pointing me in the right direction.
Hope it helps someone..
laters taters...

I can confirm the problem isnt to do with win dvd creator 2 for toshiba. My registry setting was at 0.
Its bascially a known problem that was fixed, however it wasnt fixed for irish people.
When windows wants to play tv it looks in the registry to find out what settings to use. There are no irish ones. Our signal is technically the same as the UK, so using UK settings fixes the problem, However the UK guide doesnt work for irish channels. For the tv to work in colour windows needs the 353 settings.
I think the guy on this thread was having the exact same problem that is fixed with the registry entry.
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=2488&tstart=75
This problem will only affect a small amount of users, The fix that comes with the toshiba drivers needs the irish settings added, Then the problem will be solved by updating the drivers.
until then any irish people can fix their black and white tv signal by adding the above registry entrys.
for trouble shooting purposes here is a list of countries where the bug is fixed... If someone complains of black and white tv on the qosmio series, this list can be checked, and if the persons country is absent, it could be the problem. To fix the problem you need to find out their country call code (+353 is ireland, +44 is UK) You also need to know the settings to add, i did this by looking at the UK settings in the file ttv2_regdata_20050111.reg that comes in the "reg" folder that comes for the qosmio tv driver.
here is the list of countries that an update of driver will work for...
"United States"
"Japan"

Black and white printing problem on Epson Artisan 50

When I print a black and white photo on glossy paper, I don't get black and white. I get a kind of purple hued black and white. Black text below, however, is perfectly black. So it seems it's not some kind of fault with the ink. I am choosing "black/greyscale" rather than "color". Any idea why this is happening and how to fix it? I have tried printing from different apps, including Preview, and same thing happens. Also different black and white images.

Yes, should be, but I'm not. Epson ink, Epson paper and same problem. The image is black and white. Converted in Photoshop. Print is set to "quality". Epson controls color. Not vivid. Paper is set to glossy. All as it should be.
What I have found by searching is this quote:
"Inkjet printers use their color inks and the black ink to generate B&W prints. But there are some noticeable drawbacks in doing it this way. Namely the possibility of having a color cast on your B&W prints, which is a barely perceptible color tint (usually green or magenta) that prevents your print from being true black & white.”
Other pages confirm this issue, so it seems that you just can't get decent, true black and white with a color printer. At least this color printer.
Do you find that when you print a black and white image you get true black and white with no color cast? Interestingly, I do when I print on plain paper, but not on glossy.

Brightness keys not working anymore and screen frequently flashing black and staying black!

I had my macbook pro in for repair twice last month. They replaced the logic board and had to take the screen off and look at it due to there being a potential crack. Now, when i got the macbook back the first time, after replacing the logic board, everything was fine, the brightness keys did not work at first but a restart fixed the problem. 5 days later i had it back in so they could look at the screen because i thought there was a crack on it, which turned out just to be some debris on the inside! Still had to pay a 50 quid inspection charge!
ever since the macbook has returned from this the brightness keys have had a delayed response in that, when i increase or decrease the brightness it took about 10 seconds for the screen to actually change. This happened everytime.
A few days ago for no reason, the screen started to occasianally flash black. It wasnt a problem at first, but sometimes it flashes back and stays black so i have to restart my computer. Sometimes when returning from sleep it stays black as well. On top of this, the brightness keys have completely stopped working all together now.
My laptop is not in warrenty anymore, it ran out after i got it back the second time. I was too busy with work and i needed to use the laptop so i couldnt really sort anything out.
Is there any policy saying that if the laptop comes back from repair and has new problems not caused by the customer, but by the repairer, then they will fix it free of charge?
Many thanks

nobody can help??

Why is background black and text black so you cannot see what you are typing

Why is the background black and the text black. You cannot see what you are typing or read the text of posts?

Hi dlwhit,
I'm not sure what you mean by the background and text being black. The sidebars are black, but the text is supposed to show up on a white background. I haven't seen this, nor has anyone else reported this issue yet.
Can you give more information where you see black on black text so we can try to correct it?
Thanks,

Gnome: at random times, screen fades to black and stays black

I'm having a strange issue with my gnome based netbook (Aspire One).
Sometimes, the screen will fade to black without any user input. It looks like the screen is powering off and preparing to go to screensaver/blank screen mode, but I cannot unlock it.
Its just the screen, I can go to tty1 (blind), login, and the computer will respond to commands such as shutdown.
I tried turning off the screensaver in Gnome settings + turning off screen blanking in Gnome Power Management, no luck.
Checked all logs, didn't find anything suspicious. Any ideas?

I'm having the same problem, at random times the screen goes black, nothing else changes, I could keep with a conversation on skype. Also sometimes the screen flickers, by the way I'm also using Gnome. I have the impression that this started since the last Kernel update and looking at the logs I found the following:
In the dmseg.log :
ACPI: I/O resource 0000:00:1f.3 [0x18e0-0x18ff] conflicts with ACPI region SMBI [0x18e0-0x18ef]
ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
I also noticed that if I close the lid of my netbook and open it again the screen appears again. I would like to find a solution to this problem but I'm not very experienced.
EDIT: I do use an intel card -- 945GME --, and the flickering seems to be from this bug on Intel Cards:

My iPad just went black and the black travels up and down or side to side and I can't force it to close I don't get the red bar what's going on

My IPad just went blank/black/gray sometimes lines cannot force close as the red bar does not come up
The blank screen color travels up and down or side to side
What is causing this
Either way when plug in or not the battery level is at 70%

Try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Rich black needs to be designed?

In ID (CS5) preferences, it offers an option of "Accurate blacks" or "Rich blacks". As discussed before, "Accurate blacks" are 100%K and "Rich blacks" are a combination of CMYK. Am I assuming correctly that if you have designed a black box in InDesign and want it to print with a rich black, as well as choosing the "Rich black" option in Preferences, you also need to 'make' the black out of CMYK (such as 60C, 50M, 40Y, and 100K). You can not just choose the 'Print with Rich black' preference thinking it will change all of your blacks into rich black mixtures. Is that correct?

BobLevine wrote:
FWIW, my opinion is that anyone doing work destined for press should have both setting at accurate. For press you need to create and assign a rich black swatch.
I'm a print guy, and I disagree with Bob on this. I keep my dispaly set to accurate, becasue that affects what I see on screen, but the output setting has no effect whatever on exported PDF, which is the preferred file for handoff, so in essence the setting is pretty irrelevant for press.
That said, it DOES affect PRINTING to PDF using composite grayscale as the destination. If set to output accurately, 100%K is reserved in the output for rich blacks, and your 100% K type will print as a screen to reflect that it is lighter than a rich black. Small matter, and if you don't print to PDF or desktop printers, it really doesn't matter.

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.

What "rich black" does AI use?

If I set my prefs to "Output All Blacks as Rich Blacks" what is the CMYK breakdown of this black? I usually make my own rich black, based on what kind of printing I'm doing (and set the pref to output accurately), but I was just curious what AI uses and why.

@Bernie X:
Here's some "fact", not "theory". Your printer is not printing Registration… guaranteed. They fix it and don't tell you (and don't bother calling the sales guy since he would NEVER tell you the truth of it… another guarantee.)
The interactions of ink on paper dictate a specific total ink coverage and there is not a combination (though there could be some hyper-substrate I've never seen, though unlikely - definitely not just "coated stock") that would properly withstand this level of ink saturation. Ink would be offsetting on the other sheets like mad! Even if you dried between press passes (which would add days to your print job - not economically feasible and no printer in their right mind would do it regularly) and added driers and whatnot, at a certain point ink is not going to trap properly (and I'm talking about ink-to-ink trapping).
And since you want to toss around credentials, I've been doing Prepress (conventional and electronic), running many different presses (web, offset, flexo, etc), and even bindery for 23 years, and commercial art for 30 years. I'm the guy that fixes the files people like you send in - and as a pressman I would have kicked those plates back to PrePress the minute I saw them (if they happened to get through, and as any knowledgeable pressman would do).
Just an FYI, the ISO standard for Rich Black is 50c 40m 40y 100k. This is also accepted in the GraCol7 standard though there is some anecdotal evidence that sub-Dmax Black values (ie. 93-97% Black) may actually visually appear darker in print.
PS: Your PDF can prove nothing. It's the apple, not an orange. It is a distant cousin to the plates that were on press when your job was printed. And BTW, opening your PDF it's immediately obvious that the file needs to be fixed.

Setting up Colour and Black and White in one document

I hope this is a stupid question. I am creating the school year book for the first time. It is 80 pages with a mixture of black and white pages and colour pages.
Do I have to set Indesign up any special way so that when it goes to the printers it will know this.
Can I have black and white masters and colour masters in the one document?
Do I need to gray scale all my (black and white images) in Photoshop first?
Do I need to do anything to the text to make it print in Black and white if I am using a black coloured font???
Thank you for your help.............it is greatly appreciated

>Do I have to set Indesign up any special way so that when it goes to the printers it will know this.
Maybe. How is it going to be printed? Have you talked to the printer about it?
>Can I have black and white masters and colour masters in the one document?
In a sense, yes. ALL pages in ID are color pages, but you can certainly set up masters where the only color used is Black.
>Do I need to gray scale all my (black and white images) in Photoshop first?
InDesign CS6 introduced export to grayscale PDFs, but that turns everything in the PDF to grayscale so you would need to export your color pages separately from the grayscale pages, then recombine in Acrobat pro, or send to the printer in separate files. You also need to set your Appearance of Black settings (in the prefs) to Output All Blacks as Rich Blacks if you are going to export to grayscale or your black type will be screened to a dark gray. Personally, I'd do the conversions in Photoshop so you can see and control what is going to happen and avoid the export hassles.
Grayscale content is output in the K channel of the InDesign file, and your screen preview may not be accurate unless you use overprint preview.
>Do I need to do anything to the text to make it print in Black and white if I am using a black coloured font?
Your text will print in whatever color is you choose for it. If you use the default [Black] swatch, it will output using only black ink.
