CMYK Jpegs appear lighter and desaturated
Hey everyone,
I'm having an annoying issue with my CMYK images. I work for a marketing co. that's primarily print, and after uploading my images to our online storage interface (we use Egnyte), the jpegs appear "milky" or lighter and desaturated than what they do on my screen and in Photoshop. I've tested tiff, jpeg and pdf and they all look fine on my screen, but the jpeg and tiff appear "milky" only on my collegue's screen, but the pdf is fine. She is on a Mac, I'm on PC, and no matter how I open the images, whether I redownload them from the web, or open them straight from my hd, they appear just fine.
Thanks for any and all help
Andy
How are you viewing those JPEGS?
Most web browsers do not know how to display CMYK JPEGs, much less how to use the profiles from those images.
Acrobat does know how to display CMYK, and use color profiles.

Why does the same RGB color appear lighter in one ai file and darker in another?
Why does the same RGB color appear lighter in one ai file and darker in another?? I want to use the more vibrant color, but when I try to reproduce the same RGB color code in another Adobe Illustrator (ai) file, it shows up darker. I printed the two files out, and you can see the difference in the print too. I exported the color orginally as an eps file from an ArcGIS map.
Any insight is greatly appreciated!
AnneYou illustrator files may have different color profiles attached.
Set to show your color profile in the bottom left of each document by using the flyout menu >> show >> document color profile
Then you can use edit >> assign profile to get them the same
Yours are quite far off for RGB (which are usually close to each other for many profile due to wide gamut). I question as Jacob did if one of your documents are in CMYK mode. Look in parenthesis after the document name at top of window.
Check if view > proof setup is the same (do not use the uncoated profile as in my screenshot, that was only there cause of my testing)
Make sure view >> proofs colors is checked or unchecked for both.
To get them to print the same, check these settings are the same
Sorry for all the screenshots, but hopefully one day we will see Adobe's complex color management united all in one window. -
Light and dark solid grey vertical lines appear randomly on screen
This has happened about 4 times in the last couple of months, when these light and dark solid grey lines appear on my screen, I have to turn my computer off by holding down the power button and rebooting it, it fixes the problem for the time being. These lines appear randomly, they have appeared when using Photoshop CS6, also when just using the internet, listening to Pandora. 1 out of the 4 times these lines appeared, there was a ticking/clicking noise... I took it to the local computer shop and they did tests on it twice and found nothing.

Help! My ipod classic is frozen. Even when I attach it to a power source and try to reset it (as per the instructions above), the apple logo never appears. The only thing that happens is that the screen turns alternately light and dark. Thanks!
If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
http://docs.info.apple.com/article.html?artnum=60983
If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
Make sure you do all the following “TRYs”
A. Try to wait 30 minutes while iPod is charging.
B. Try another FireWire or USB through Dock Connector cable.
C. Try another FireWire or USB port on your computer .
D. Try to disconnect all devices from your computer's FireWire and USB ports.
E. Try to download and install the latest version of iPod software and iTunes
http://www.apple.com/itunes/download/
For old and other versions of iPod updater for window you can get here
http://www.ipodwizard.net/showthread.php?t=7369
F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
http://www.apple.com/support/ipod/five_rs/
G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
http://docs.info.apple.com/article.html?artnum=93651
If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
Intermediate Level
A. Try to connect your iPod with another computer with the iPod updater pre-installed.
B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
For Mac computer
1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
5. Eject your iPod and do a Reset
6. Open the iTunes 7 and click “Restore”
For Window computer
Go to folder “My Computer”
Hope you can see your iPod there and right click on the iPod
Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
Now select “Format”
Eject your iPod and do a Reset
Open the iTunes 7 and click “Restore”
In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.

C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
Tips
a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iTunes 7.
b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

Advance Level
A. Diagnostic mode solution
If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
iPod 1G to 3G: "Menu" and "Play/Pause"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
iPod 1G to 3G: "REW", "FFW" and "Select"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
B. Format your iPod with a start disk
I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
If none of these steps address the issue, your iPod may need to be repaired.
Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
Or visit your local Apple Retail Store http://www.apple.com/retail/
In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ or ifixit at your own risk
http://www.ipodresq.com/index.php
http://www.ifixit.com/
Just in case that you are at the following situation
Your iPod warranty is expired
You don’t want to pay any service charges
You are prepared to buy a new one
You can’t accept the re-sell value of your broken iPod
Rather than leave your iPod as paper-weight or throw it away.
You can try the following, but again, only do it as your last resort and at your own risk.
Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
Last Resort Level
1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)

2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

I am not suggesting that you should follow as well, but just read them as your reference. You are the person to make the call.
Finally, I read a fair comments from dwb, regarding of slapping the back of the iPod multiple times
Quote “This has been discussed numerous times as a 'fix'. It does work, at least for a while. In fact I remember using the same basic trick to revive Seagate and Quantam drives back in the mid to late 1980's. Why these tiny hard drives go bad I don't know - could be the actuator gets stuck in place or misaligned. Could be the platter gets stuck or the motor gets stuck. 'Stiction' was a problem for drives back in the 80's. Unfortunately the fix can cause damage to the platter so we temporarily fix one problem by creating another. But I know of two instances where a little slap onto the table revived the iPods and they are still worked a year or more later.”UnQuote -
I see inconsistent ImageNew() failures for CMYK Jpeg Images (CF10)
Weird problem.
I have a set of test cases that pass just fine loading a known CMYK jpeg via ImageNew(). Later, with no restart of the app server, these same test cases fail. Again, after a while, the test case passes again. I've dug into the Java a little bit, and I wonder if the ImageReader implementation being used doesn't switch out once in a while -- like maybe a hashtable of ImageReaders reorders or something.
I know the CMYK is only partially supported, but I could get data with ImageNew and ImageInfo showing it was a CMYK file, then later on, it would throw "Image Not Supported" errors.
Anybody have knowledge of these inner workings to provide some insight? Smells a bit like a bug to me, but I can't consistently replicate it.
-DaveFrom what I can tell, it does appear to be a bug. I have submitted a bug report to Adobe on it.
https://bugbase.adobe.com/index.cfm?event=bug&id=3596008
What seems to be occurring is that coldfusion.image.ImageReader is trying to find the CLibJPEGImageReader class from the collection returned by javax.imageio.ImageIO.getImageReadersByFormatName("jpeg"). This works fine if it is the first object returned in the collection, but if not, it will return another JPEG ImageReader that does not support CMYK images. I have two systems (both RedHat) which are currently in each state. One has the CLibJPEGImageReader as the first element in the ImageReader collection, and in the other, it is the second element in the collection. The code below will work fine when the correct reader is found, but not when it isn't the first element in the collection. -
Video set to stop on last frame appears lighter than last frame
I've got a video set to "stop on the last frame" using the technique described here:
http://digitalpublishing.tumblr.com/post/6141054971/how-to-make-a-video-stop-at-the-last-f rame-here
Works great. But whenever I do this, there is a slight darkening when the multi-state object appears at the end. To create the image for the multi-state objects, I opened the video in Photoshop, grabbed the last frame, and saved it as a JPEG.
Anyone have any ideas? I've tried saving the end image as a PNG, lots of other workarounds, but the problem persists. I've noticed this in other publications I've downloaded also, so I think the problem is widespread.great to see this trick evolve in a first-frame-lasf-frame-method, wich I
thought about,too lately.
Will post an update in my article next time ii get the chance.

Pdf's created in Illustrator appear lighter in Adobe Reader
Hi
I've been using Illustrator for a few years for web design and print graphics, fliers etc. I have noticed that when i save a design as a pdf in illustrator then open the pdf in adobe reader the colours all appear lighter than they should be and print lighter aswell. Is this common? I've been wondering for a while but never figured it out.
Thanks
PaulWhen you Knockout the colour it should cut a hole in the shapes below it -
Start by creating a New Black Swatch
Then Apply that swatch to your black frame
Below I have turned off the Black Separation, and you can see that it has knocked a hole right through the items below - I've also shown you the Attributes Panel - you can see in the Spearations panel to that the black is still 100%
Below is what happens when you have Black set to Overprint
YOu can clearly see that the values are added up - You now have a 284% ink coverage here - so anywhere the black goes over the green here the values are added together and that gives you a different shade of black, because the Black is PRINTING OVER the other colours and adding, as ink is transparent, not opaque.
If the black frame goes off into the white it will be 100% for whatever is touching the white, and then 284% when hitting the green here, so you get two distinct shades of black. -
How can I load a CMYK jpeg image
How can I load a CMYK jpeg image (originally saved from Photoshop) and then
turn it into an rgb BufferedImage, in order to display it on screen in an
applet?
I first tried ImageIO.read(), but that does not work for cmyk jpegs. I then
looked into the com.sun.image.codec.jpeg package, and tried methods like
decodeAsBufferedImage() and decodeAsRaster().
The first one (decodeAsBufferedImage) returned an image, but it seems that
it was interpreted as an ARGB, and the colors were incorrect.
I then read the documentation which (amongst many other things) stated that
"If the user needs better control over conversion, the user must request the
data as a Raster and handle the conversion of the image data themselves."
This made sense, so I took to decodeAsRaster(), only to find that I could
not figure out how to carry out the desired conversion.
Of course, I have looked into the documentation for BufferedImage, Raster,
ColorModel, ColorSpace etc, but after a while I was lost. (Before I got lost
I read that you can convert images with the help of methods like toRGB,
toCIEXYZ.)
I have a feeling that this is probably pretty simple if you just know how to
do it, but I sure would need some directions here.
Any help would be appreciated. Thanks.You can either use the "Place" command from the main menu, under "File", or you can just open it, select the move tool "V", the click in the image and drag it to the other file's tab.

XY Graph Won't save to JPEG when Black and White...and run from TestStand.
I am creating an XY graph and manipulating the colors of the plots, background, etc. I am saving this graph to JPEG using the Write JPEG File vi and after it is saved I import it inot a test report. This works fine in color, but when I create a B&W plot, it won't save to JPEG. Let me clarify: It won't save to JPEG when I run the VI from TestStand. It does save to JPEG when I run the VI as a stand alone application in LabVIEW.
Problem:
Run VI from LabVIEW ~ Saves the JPEG in both Color and B&W.
Run VI from TestStand ~ Saves the JPEG in Color, but does not save the JPEG in B&W.
Here is how I am making all the plots and background B&W in my code:
Change all Active Plots to Black using property node.
Change all Active Cursors to Black using property node.
Change the Plot BG colors (major/minor grids, etc) to lighter colors using property node.
Does anybody have any suggestions?
Thanks in advance,
MikeA few questions: What version of LV are you using? How are you getting the control image that you are sending to the JPG? Third what exactly happens when you try to save the B/W image under TestStand? Error?

}The loading process It takes about 10 seconds, and every repaint it takes the same time.The painting yes, the loading no. It shouldn't take much more time to load the image then an ordinary JPEG. In particular, your now using a "natively accelerated" JPEG image reader, so it should take less time on average to load any JPEG. 10 seconds is absurd. Are you sure your not including the drawing time in that figure?
- Another problem: JAI-ImageIO is not available for MAC OS X platform.This is somewhat true. You can take the imageio.jar file and package it together with your program (adding it to the class path). This will give you most of the functionality of JAI-ImageIO; in particular the TIFFImageReader. You just won't be able to use the two natively accelerated ImageReaders that comes with installing.
Right now, you're using the accelerated CLibJPEGImageReader to read the image. You can't use this image reader on the MAC, so you have to take the approach mentioned in the 2nd bug report you originally posted (i.e. use an arbitrary CMYK profile).
The conversion is too long more than 30 seconds.The code you posted could be simplified to
BufferedImage rgbImage = new BufferedImage(w,h,
BufferedImage.3_BYTE_BGR);
ColorConvertOp op = new ColorConvertOp(null);
op.filter(cmykImage,rgbImage);But again, 30 seconds is an absurd value. After a little preparation, converting from one ICC_Profile to another is essentially a look up operation. What does,
System.out.println(cmykImage.getColorModel().getColorSpace());print out? If it's not an instance of ICC_ColorSpace, then I can understand the 30 seconds. If it is, then something is dreadfully wrong.
the RGB bufferedImage that i get after the transformation when it is displayed is much more brightThis is the "one last problem that pops up" that I hinted at. It's because some gamma correction is going on in the background. I have a solution, but it's programming to the implementation of the ColorConvertOp class and not the API. So I'm not sure about its portability between java versions or OS's.

}Hi,
I am having similar problems. I have read somewhere that png format can not handle CMYK colorspace anyway, which I find odd (and plainly stupid IM(NS)HO) which would mean that converting to RGB and therefore using profiles is mandatory.
May be you should check if the internal format of the png files claims it is RGB or CMYK (using ImageMagick's "identify" command for example).

Preview - saving resized CMYK JPEGs
I can't save a resized CMYK JPEG with Preview:
Take a JPEG, any JPEG.
Duplicate it, make an RGB and a CMYK version (create whichever one did not already exist) using
GraphicConverter or a similar tool.
Open each in Preview and use "Adjust Size..." to adjust the resolution.
Save. RGB version saves fine. CMYK version fails with "The document 'CMYK.jpg' could not be saved."
Can anyone confirm or deny?Just been bitten by the same problem. It seems to work fine on Leopard but seems broken in SL?

My photo booth screen is very very dark. I thought it was the screen but its at the brightest it can possibly be! So I grabbed my mothers MacBook Pro and It's much lighter and more clear. I have just the regular macbook. I also used the my camera on tumblr and it came up like my mothers. So could it just be photo booth? I also have no idea how to find out which operating system is downloaded. This is preowned.
Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps. -
Upright JPEGs Appear On Their Side When Imported To FCE?
I have imported numerous upright (Portrait View) JPEGs into FCE and they all appear on their sides (Landscape View).
They were converted to appear correctly oriented in Photoshop and Preview but refuse to behave in FCE.
I know I can use the Motion window to rotate them but there is a very large number.
How do I batch do it and more importantly is there a way of making FCE recognise from the start that they should be upright?I have just batch converted the JPEGs to TIFFs in Photoshop and they display correctly in FCE.
It looks as though it is a JPEG "feature" ......... is there any way of handling JPEGs to stop this behaviour or must I always convert them to another format? -
I got my bb 9300 a couple of weeks ago. my problem is that it suddenly shuts off and the led would turn to red light. it won't turn on. I thought it was just battery empty or something so I charge my phone, it them keeps on having red light and then keeps on having this image of no battery or something. It did turn on one time then vibrates hard and then turns off again. After that it won't turn on. just red light, no battery. Please help.
If you tried a wall charger (that previously worked with your shuffle) and computer ports, the most likely cause is a problem on the iPod. At seven months, it may not be the battery (although it sounds like you use it a lot every day), but it sounds like the battery is unable to charge.
Does the iPod still appear in iTunes when you connect it? If it does, you can try doing a Restore using iTunes.
Restoring iPod to factory settings - Apple Support
If the wall charger is something you did not previously try, it's possible that the computer's USB port is not supplying enough power. As a test, shut down (power off) your computer and disconnect all USB devices (including any hubs). You can leave standard keyboard/mouse connected, if used. If the computer is a laptop, connect its power adapter so that it's not running on battery power. Put the shuffle power switch in the OFF position. Start up computer, run iTunes, and connect iPod to a direct USB port on the computer.
At seven months, it is still under warranty.
