Some RGB files produce no Black Separation

We are a commercial printer. I've seen pages on many jobs recently where RGB images are converting to CMYK using SWOP profile, but no black sep information is present. The image separates into 3 colors only. When exporting from ID, we suggest leaving color unchanged, since our RIP has always done a great job of converting RGB to CMYK. Has anything changed in CS5 that would cause this?

There has been no changes in Adobe color management since at least CS2. Color management is turned on and is unified throughout the Creative Suite if you're using default settings.
Choose Edit > Color Settings and see if your InDesign settings are Synchronized with the Suite.
If you're outputting directly from InDesign, you might try resetting your InDesign preferences. Perhaps something has gotten screwed up:

Some PDF Files Shown with Black Background and White Text - Annoying

Hi All,
Recently some of my pdf documents, stored on my phone, are displayed with a black background and white text. This is quite annoying. A few weeks ago I didn't have this problem. All of my pdf documents had a white background with black text.
I'm a new iPhone user without much experience with the device. I have the 4.3 version of the software and update when prompted. I use Files Pro, FileApp Pro and QuickOffice applications in conjunction with DiskAid.
If there is something I can do to correct the situation, please let me know. If the problem is with Apple, they need to fix the situation. My phone, which used to be a great device for storing documents, has turned into an annoying bug.
Thanks,
Mike

Opening large photo files produces black screen

When opening a small (less than a meg) photo, it works find. I'm able to move to the next file. If I open a large file (8-10 megs) it sometimes works fine however if I use the arrow to move to the next file in the folder I get a black screen. Also if I have a folder of many large photo files I can see all the thumbnail photos at a small size. If I try to increase the view size to large some will be black, however if I click on the file many times it opens fine, sometimes not. It was working fine, just recently started to act up. Using adobe photoshop I can open each file so I know they are there and not corrupt files.

Some files have a black overlay, cannot read

This is not an online problem. Some pdf files and some pages of some files have a black overlay, and I cannot read the material. I can select all and copy, and it will show the text (only) in Word, and I can print the file without a problem, I just can't see it on the monitor. I've tried "show large images," and I've tried changing the reading order. Nothing works. What should I do?

I have solved my own problem, in case anyone has the same one: I unchecked "use 2D graphics acceleration" in the Page Display. No black overlay now.

Some snaps show up as black screens when I try to view them as single pictures.Even when I run them in slideshows they show up as black screens.These are jpeg files.How can I avoid this happening?

Some snaps show up as black screens when I try to view them as single pictures.Even when I run them in slideshows they show up as black screens.These are jpeg files.How can I avoid this happening?

There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

Iphoto will not import some jpeg files after many attempts to 'fix"

I have scande images into my iphoto until i updated to iphoto 9. now it does not import jpeg for some reason. some jpegs are more equal than other how ever some go in some do not. So what is wrong with iphoto 9 and do i need to reset some profile something somewhere.
mac book pro 17 standard edition no mods 2.6 intel core 2 duo 4 gigs memory 1067 mhz ddr3
files are saved to desk top folder as a jpeg in either color or black and white using the system Image Capture software.
1) the error is -20
2) i tried importing some old files in and out they seem to work
3) shut down restarted and tried again no joy with the scanned images
4) all images are openable by preview and can be changed to tiff
5) iphoto allows tiff in but not the jpeg or any kind
6) upgraded to iphoto 9 and this started is there a profile file i should through away and what is the implications of doing this ? i have many thousands of photos i do not want to lose.
i need to use jpeg format for my family and work.
any suggestoins.
7) rand disk permission repair from install disk no problems
8) should i start in safte mode and do a PR reset.

1 - iPhoto does not accept grayscale images - they must be RGB even if the photo is B&W
2 - sometimes opening a photo in preview and doing a save as and then importing the new JPEG will resolve this type of problem

Problems converting layered rgb files with transparency to cmyk files retaining the layers.

10.7.4/Mac Pro/PhotoshopCS6 13.0 - When cmyk converting a multilayered rgb file layers containing transparency doesn't convert to same profile as layers not including transparency, e.g. a product with a shadow - each on separate layers. the product layer is converted to working Color settings but the transparent layer isn't and is converted completely different, both grayscale and UCR/GCR.
Any suggestions?
Tom

Sorry c.pfaffenbichler, but I'm not giving in - and as you have not really produced any facts to explain this I will see this as a Photoshop bug.
If you make a simple two-point gradient in CMYK the gradient will (according to your settings) create a transition between the two colors.
If one of the colors is 87/78/64/92 and the other 0/0/0/0 then the resulting intermediate steps will depend on those two colors – the CMYK space’s GCR settings have no influence here.
Edit: To clarify: The CMYK space’s GCR settings determine how the default »black« is formed, but a gradient in CMYK is not dependent on those GCR settings. Otherwise all gradients would have to be dragged through the PCS and that would not make sense if somebody decides to make a gradient with certain CMYK colors.
And as I have tried to explain: A black to transparent gradient layer is basically a black layer with a transparency, so again: the CMYK GCR settings do not play into this.
Just convert a RGB black to transparent Layer to CMYK, rasterize it and then apply Layer > Layer Mask > From Transparency, then turn off the Layer Mask.
Whether you »give in« or not does not change the way these things are.
knowing there's a flaw in Photoshop, not letting us see what transparents really look like when converted...?
The flaw seems to be in your understanding, not in Photoshop.
Working in RGB and CMYK has relevant differences.
In RGB there is true black, in CMYK true black would have to be 100/100/100/100 which would violate the requirements for many or most processes.
And a CMYK space’s GCR settings are applied in conversion, when you yourself work in CMYK and commit a blunder (meaning things like exceeding the TAC, arbitrarily mixing grays, …) the problems are of your own making.
Edit: To restate: »expecting a layered image to appear identically in RGB and CMYK is simply not sensible depending on the image content and structure.«
The two color models are inherently different, the one additive, the other subtractive.

Can I print RGB files since they are closer to what is on screen?

Greetings,
I have an important question about how to set up my files for print. In school I was taught to work in CMYK or at least convert whatever RGB file I'm working on to CMYK. I'm at work now and the files I am printing are coming out dull (in CMYK). I converted a file to RGB and assigned the RGB 1998 colour space and re printed it. The first CMYK print looked grey and was not vibrant. The new RGB print printed very vibrant and matched the screen colours better than the CMYK. My boss wants me to do the rest of the prints in RGB seeing as it prints with better vibrancy. Also, I am working in Illustrator.
So my question is: Can I convert all my CMYK files to RGB, send them to the printing company and expect the prints to be vibrant? Or will converting my CMYK files to RGB mess up the printing companies standards?
RGB prints better, but I was taught to always print in CMYK mode.
I appreciate the help.
F
Actually I'm going to leave the files in CMYK since turning them into RGB may cause colour loss during the final large prints. I will print the presentation files in RGB though.

Quinonez,
It sounds as if your printer (driver) in non PostScript, and made for receiving RGB documents which are then converted to CMYK on the printer side.
When you use it for a CMYK document, it will first convert to RGB then back to CMYK, in other words a double conversion, which ís just about as bad as it sounds.
For such a printer, it is better to start off in RGB, but that may land you in the issue of having different bases for print.
You may get round it with the PS Printer Kit-Q3 to add PostScript 3 emulation printing capabilities, mentioned here (fifth dot in the Features list), which will hopefully give you at least as good colours as you have with RGB:
http://www.digitalcopier.org/canon-digital-copiers/canon-imagerunner-ir-c3480
Canon's proprietary UFR II printing technology is standard on every model. That means every Color imageRUNNER system is a true MFP right out of the box, ready to produce volumes of general business documents. Customers also have a choice of two print controller options, imagePASS-J1 or PCL Printer Kit-Q3, for expanded printing functionality. For customers who do not require true Adobe PostScript, the device can also be equipped with the PS Printer Kit-Q3 to add PostScript 3 emulation printing capabilities.

ITunesSetup says some install files are corrupt, iPod wont be read by pc..

My ipod and itune were working fine earlier today and before, but whenever i try to update to the latest verion the install says some install files are corrupt, and now my itunes suddenly no longer reads my ipod... This is like the 20th time this ipod not being read by pc problem has occurred and it's really making me never trust apple with pcs again.

2. "I ran the system rescue cd and fsck'ed both partitions" -> Did you get any direct filesystem error message from the system?
3. What happens if you try to delete the corrupted files and restart ? Does it become corrupted too every time?
4."X sometimes won't start, I get a black screen and I need to power down by holding the power button." -> Which driver/kernel/xorg version do you use ? I've experienced such a situation with the nvidia-185.18.31 driver.
Thank you for your quick response.
1. Is it safe to delete the corrupted files in /var/log? I already deleted viminfo after it got corrupted the first time, but it happened again.
2. In the rescue cd, fsck quickly said "it's ok" without checking. Is there a way to force it to check? The man page doesn't say. The longer check I get sometimes when booting ("hasn't been checked in the last X mounts yadda yadda") shows only "fixed write time in the future" from time to time.
3. The Xorg.0.log particularly gets corrupted after the hard restart that I issue when X fails to start and a black screen locks up the pc.
4. xf86-video-ati is 6.12.2-2, kernel26 is 2.6.30.4-1. xorg-server: 1.6.3-2. The black screen issue will be (I hope) solved in the other thread I made (link in first post), but I have the suspicion that both problems are very closely related (one is the cause for the other, or some sort of vicious circle.)

Won't boot from install discs after deleting some system files

I've been looking through the forum and haven't found an answer to my problem - maybe someone can help me out.
I have an aluminum Powerbook G4, 1.67, 1.5 RAM, 10.4.11. I was experiencing the problem with FCE capturing video for about 5 minutes and then freezing, and I read some threads here about how this can be fixed by returning to Quicktime 7.2 and installing it with Pacifist. I did this, but first tried to delete my previous Quicktime version files, and obviously I deleted some system files in the process. That's how my new problem started.
Programs now that do not open - Preview, iTunes, iMovie, FCE, Yahoo, Mail, and Microsoft Messenger. I no longer have my date/time/battery level/airport/bluetooth indicators in my toolbar. The Spotlight icon flashes, but will not open. Also, when opening the System Preferences pane, it opens just for a second or two and then crashes and closes. Safari, airport, and Word all work, though, and I still can access internet.
I tried to re-install OS 10.4 from my black install disc. The computer reads the disc, but after I click the installer icon and then "restart," the computer fails to completely reboot. The disc spins in the drive, I get the Apple, the indicator, and then the screen goes to blue and the disc soon stops spinning. Nothing happens after that. I've tried rebooting by holding down the C key but the same happens. When I hold down the option key, I get to the point where I can choose to boot from the install disc, and then the same thing happens - the blue screen and nothing more. Booting with the shift key held down doesn't work either.
I did just have a repair by Apple - my adaptor plug sparked when inserting it into the outlet, and I had to have the logic board replaced. But the computer seemed to be working fine when I got it back, except for the FCE issue first mentioned. Looks like my good intentions have done me in.
The install disc is about three years old, and is in good condition. It's been in the garage, so could heat or cold affect the readability of the disc?
Does anyone have any suggestions on how I can boot from my install disc and get a fresh install of my OS?

Hi bboross,
Tough without a Tiger Disk, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
(space between fsck and -fy important)
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: ** The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, reboot once more.

When I open a pdf in Adobe Acrobat xi pro it is not displaying correctly. If a file is all black with orange writing, I will see only the orange writing. Its not until i print it or open crop pages dialog box that i see the background.
i am on a Windows 7 professional PC, 64-bit.

If anyone is reading this still looking for what caused the issue and how to fix it here is what I discovered.
The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.

No thumbnails for some .mov files Bridge CS5

I'm using Bridge CS5 to organise some video which has been digitised from a sony camera in File Maker Pro X. My operating system is Mac OS X. I have Quicktime player 10.1 and have just checked for updates.
Some of my .mov files show thumbnails which can be watched in Bridge. Other folders just show the thumbnails as black rectangles - these can be watched in a pop up window but not directly in the Bridge preview panel.
The files were all digitised in the same way and recorded on the same camera so should be the same format.
After looking at discussions on here I have tried updating QuickTime and clearing the cache but no dice.
Any suggestions?
Thanks,
Claire

That is odd that if it was recorded on same camera they are different. I do know that the thumbnail is a complex issue. A little foggy on this as it has been awhile, but if you get a black thumb it is the way the marker of the first frame is recorded. In some cases this shows a black frame. Hope this gives you some clue to do a web search for the real answer.

Photoshop CS Extended can't open some PSD files

Hi,
Yesterday I have created a new PSD file and worked on it and finally saved the file, but now i can't open the file any more. PS always fails to open the file, because of an internal error.
I have tried to open some other PSD files, but 3 of 4 files (on my current HDD) didn't work to open and i don't know why. All of those other PSD files are at least 1 month old and PS could open these files. The last time i have opened these files was two weeks ago. The one PSD file, that worked has the following properties:
image: 1179x1528, 72ppi,8bit,RGB, 15,04 MB
and the files that don't work have the following properties:
image1: 454x340, 71ppi, 16bit, RGB, sRGB (profile), 1,17 MB
image2: 1280x1024, 71ppi, 8bit, RGB, sRGB, 1,92 MB
image3: 1191x1644, 71ppi, 16bit, RGB, sRGB, 12,02 MB
I have got, the meta-data out of Adobe Bridge. I can see the preview Image and the thumbnails in the open-dialog of PS. I tried to open the file with other applications like Paintshop Pro and PhotoImpact and both couldn't open them. Paintshop Pro quits, because it doesn't support the "color model".
I don't know, what else i can do to open these files. I looked around the forum but couldn't find any solution for my problem.
Does anyone know a solution for my problem ?
evangelion2100
PS: I have deleted the pref-file of PS and still it didn't work.

Dear all. After getting the same problem and read all possible solutions online with no success finally I got rid of this problem successfully and Now it is working perfectly again, and I hope It will work for you all.
Here it goes:
BACKGROUND (my case): PS CS3 installed (Premium-Extended), Win Vista 32 Bits. For months it was working perfectly until yesterday, when the app stopped when attempting opening some PSD files. Some other CS3 apps either stopped. 1st I thought it was some kind of file corruption issue.
After 3 uninstall-reinstall attempts of the whole CS3 and still troubleshooting, I went to the Vista Error Log. Regarding PS CS3 there was a DLL file named "CoolType.dll" which was suspicious to be the main cause of this ****.
Making a research, it relates to installed Fonts in Windows, that gave me the clue to all of it.
Yesterday, I installed fonts while working with PS CS3 Im now pretty sure that this process someway altered the Cooltype.dll file, or fonts were not installed properly.
SOLUTION (my case): locate and uninstall recent fonts (which may have been the problem). NOW my PS3 CS3 is working more than PERFECT!!
HOPE THIS CAN HELP. I think this topic regards some kind of failed font installation. Check it out and remember if you have modified something.

Can only open some JPEG files in Camera Raw through Bridge CS3

I'm running Bridge CS3 version 2.0.0.975. I always edit my JPEG files through Camera Raw in Bridge CS3. I only have to Right-Click on the file and select "Open in Camera Raw...". However, I've come into a situation where some jpg files will not open this way; the option is not even there.
I have made sure to tick the box in preferences under Behavior "Double-Click Edits Camera Raw Settings in Bridge", and also tick the box under Thumbnails -> Performance and File Handling "Prefer Adobe Camera Raw for JPEG and TIFF Files.
These files were originally 16bit Grayscale TIFF files, but I changed them to RGB 8bit JPEG files.
Also, I know the program works because I navigate to an older photo I worked which is a JPEG and the "Open in Camera Raw..." option is there when I Right-Click, but then I navigate back to the image I want to edit, and the option is not there.
Here are links to my screenshots of what I'm talking about. Both images in the last two screenshots are JPEG:

That's a fundamental problem right there, and a clue in all this. You should be able to see JPEGs in the Open As Camera Raw dialog.
What happens if you type in the name?
I'm almost convinced you have a file named .jpg but with a different image format inside. Can you put one of these files online for others to try to open?

Avi files showing as black

Hello, recently some avi files started showing as black in AE. The same is the case when rendering a project containing these files.
Even if I look at my old projects and such, some of the avi videos display as black there also, so what worked before doesn't now.
The specific avi format, that doesn't show properly, should be OpenDML Avi 2.0. All other video formats work as they always did.
I'm guessing that some file or codec got deleted, but outside of AE the files play without any problem.
Is there some way to resolve this? I've already tried reinstaling AE, resetting the preferences..
I'm using Windows 7 and CS6.. not sure what else is relevant.
I'll be grateful for any help.

Oh, alright, sorry. The codec is Motion JPEG.
I don't recall changing anything before this happened. I did probably install some games. Not sure if that would cause something this specific.
I've just tried uninstalling all third party codecs and nothing's changed. I've tried reinstalling them after that and nothing's changed again.
I don't know how to reinstall the Motion JPEG codec as mentioned by Rick Gerard, so I didn't do that part.
