Does Lightroom convert images to CMYK?

I need to convert images to CMYK to submit photos for an article. I know Photoshop will convert, but don't know which software. If Lightroom does not convert to CMYK, which would I need to get?

Yes, you have to install the profile on your computer. In Photoshop CSxx you go >Edit >Convert to Profile, and select the CMYK-profile under <Destination Space>. In Acrobat you go >Edit >Color Management, and select the profile under <Working Space>. But only Photoshop will convert the image to CMYK, whereas - at least for my understanding - Acrobat will display the image as if it were CMYK but not actually convert it.
If I do the conversion here (open their images in PS or Acrobat and convert the profile) aren't I still stuck in the 'I don't know what shade of pink you want that flower to be' still anyways?
If you get a RGB image from a client, you have to assume that the colors are as wanted. This is not different when you get a CMYK image. The problem for you is that nor everybody has a calibrated monitor, so an image might look good on their monitor but the actual color numbers will produce a print that looks different. But there is nothing you can do, except - if you have the time - adjust obvious off-colors. For instance you know the skin-color of caucasian (white) people. You know how green a lawn is, and you know that most brides wear a white gown. So if for instance the gown is blue-ish, or the skin looks overly pink, you can adjust that. More you cannot do. In case of a flower you can only accept the photo as is - unless you know this type of flower very well.
But the evaluation of color is only possible if you have a calibrated monitor that is re-calibrated regularly (every week or so). If your monitor is not calibrated you have no way of knowing if the off-color is due to the color numbers of the delivered image or a result of your un-calibrated monitor that displays the colors differently than the color numbers warrant.
If you use a calibrated monitor the colors should not change on conversion to CMYK. You can use the Softproof feature in Photoshop to check if colors are out of gamut.
- my degree is in design, yes, but we didn't cover printing and prepress specifics at all.
Yes, I have noticed in my work that the designers often have no knowledge about color management, printing, and pre-press. Good on you that you care and want to learn!
Keep on asking if you wish.

Converting Images to CMYK for Print Publication

When in my workflow should I be converting images to CMYK for print publication?
Currently, I shoot RAW photographs with my DSLR in Adobe RGB, import the images into Photoshop for manipulation and then convert the final, sized image to CMYK before placing it in my Indesign document. Before going to print, I convert my files to PDF using the [PDF/X-1a:2001] preset. I use a calibrated system with a profile set for my monitor.
Since many of my pictures have shades of green, I'm often disappointed with the conversion to CMYK because I lose saturation and brightness. Am I doing anything wrong? Is there a better way of preserving the quality of colour in my images when going to a commercial printer?

To see in InDesign what color shifts will occur, use View=>Proof Colors.
I would also recommend View=>Overprint Preview.
Yes there are color shifts when converting RGB to CMYK, but those are due to the fact that the gamut of CMYK is significantly less than AdobeRGB or even sRGB. The same color shifts going to CMYK will occur whether you convert the image in Photoshop or in InDesign during PDF export or at the RIP.
Keeping the color in ICC color managed RGB has the advantage that last minute changes can be made as to what CMYK printing conditions are used, i.e. all CMYK is not the same. Furthermore, if you convert RGB to CMYK early in the workflow, you lose the ability to maintain the color gamut for display of the PDF as well as for printing to high fidelity color devices, i.e., offset or digital (especially inkjet) devices that have extra colorants such as light cyan, light magenta, orange, and/or green to dramatically expand the gamut. Once you lose the gamut in your imagery via conversion to CMYK, you can't go back.

Converting Images to CMYK?

Just new to LR and was hoping someone could solve my problems Re: image conversion.
Is there a way to convert RBG images in Lightroom to a 'HighRes CMYK' so there press ready? Ive been searching but cant find anything. Hopefully they havent cut this feature out?
Cheers,
Adam

And not likely ever will be. CMYK will be viewable for DAM purposes but little else.

RGB mode in photoshop is highlighted red in the menu, even after converting image to CMYK..what does this mean?...

Like above. I just am about to send a project to the printer and need to make sure there will not be any issues during the printing process like the colors coming out weird, etc...

not sure how that got there
Might have been part of a Workspace.
what do you mean by used the correct CMYK space?
CMYK Spaces, usually described by an ICC profile, describe particular print conditions (print process, paper stock, raster width, …) and therefore simply converting to CMYK
• may be OK (if the print condition corresponds to the CMYK Working Space) but
• may also necessitate re-separation and avoidable loss of quality (if the target space and CMYK Working Space differ)

Converting a document containing RGB images to CMYK (with a profile)

Hi,
I am trying to use PDDocColorConvertPage to convert all RGB images in a PDF document to CMYK (with a color profile).
I can see the API is performing some changes to the PDF however it is not performing the conversion in the same way as Photoshop or Acrobat.
Has anyone tried to do this before? Am I doing it the correct way?
Thanks
Please see additional details below:

Where does Lightroom display color space?

Where does Lightroom display color space assigned to an image? It should be in the metadata panel. In Bridge it displays Color Mode: RGB/B&W and Color Space: sRGB/Gray Gamma 2.2. Or does Lightroom convert everything to Adobe RGB or ProPhoto RGB?

LR's internal working space is a variation of the ProPhoto RGB space, ProPhoto RGB's gamut but with a linear tone curve instead of the standard gamma 1.8 curve. This is because it is primarily a Raw editor and Raw sensor data is linear and because the ProPhoto gamut will more or less include all the colors most digital cameras can capture (depending on the filters in front of the lens, some cameras may capture ultra-red that is outside ProPhoto RGB). Retaining the linearity of the data makes editing calculations easier, faster, more flexible and more accurate since data has not been lost to the quantization errors involved in gamma correction. So for a Raw file the workflow is the assignation of the camera profile and conversion from that to linear ProPhoto RGB. However, the display data from the Develop module (the data sent to your monitor) undergoes a further conversion that involves the application of the sRGB tone curve, which is sort of gamma 2.2 but not exactly. This is because linear image data looks terrible - very dark and flat. Thus, the display is in a hybrid space called Melissa RGB, ProPhoto primaries and sRGB tonal response curve. At the time of export or printing a conversion is done from linear ProPhoto RGB to the output space designated by the user, which can be any RGB space - ProPhoto RGB, Adobe RGB, sRGB or any other one, provided you have an ICC profile for it in your OS's Color folder..
Previews used by the Library module are jpgs in the Adobe RGB space.

CS2 Convert RGB Images to CMYK Within Illustrator

Hey everyone. I desparately need some help here. I designed a file in Illustator CS2 and my file had images within it. I took it to a professional printer and he said my images needed to be converted from RGB to CMYK to print properly. The printer had CS4 and he said to change the colours you click on Edit -> then Colours, which in turn allowed him to change the pictures format from RGB to CMYK. I only have CS2 and when he told me to select Edit and then Colours, well CS2 does not have that. It's something completely different.
If someone out there knows how to change the picture files from RGB to CMYK "within" Illustrator CS2 could you please tell me how as Adobe's phone support only deals with the most current version.
Any help you can provide me with, would be greatly appreciated!
Thanks in advance,
Julie

>This is for my benefit as I have just purchased a colour laser printer and wanted to be able to print something proper like the professional printer.
Unless you have a PostScript RIP for your laser printer (a separate driver provided either by your printer manufacturer or a third party) you cannot proof CMYK documents directly. Lacking a PostScript RIP, you can still get a pretty good idea if you have Acrobat. Print to PDF using settings that convert to, say, sRGB... then, print that PDF document on your laser printer (using its native non-PostScript driver).
For your older documents, if your placed RGB images are embedded (rather than linked), you can try Philip's suggestion. It shouldn't matter, though. Illustrator should do the necessary space conversions at print-time.
If the images are linked, I would suggest you convert them to CMYK in Photoshop. I'm sorry, but I do not know of a way to do the same thing within Illustrator (v12 aka CS2).

Help converting RGB Images to CMYK?

I am working with a CMYK Freehand design, and it includes a
cut out image on top layer. The image is in RGB. When I export it,
I am getting a colour shift on the transparent areas.
Should I be working with a CMYK cut out image? If so, how do
I convert my RGB image to CMYK, keeping the transparent areas of
the cut out?
Help much appreciated (ASAP)

Geoff

How are you creating the transparent areas? Are you using an
alpha
channel in the bitmap? I stopped doing that when I noticed
color
shifting (even in grayscale reproduction) similar to what you
get when
using the raster effects. But I do miss using it because it
is
convenient and sets up nicely.

When I try to print an jpeg or png from Photoshop all it does is convert the image to a PDF & plop it on my desktop- it won't print the image. Any suggestions as to how to fix this?

Yes, the printer is on, it’s selected in Printer Set-Up & I’ve never had this problem before. It’s definitely a Photoshop issue as every other type of file prints fine. I’ve uninstalled Pshop & am now reinstalling. Hope that will do the trick.

How to batch convert RGB images to CMYK

Hello,
Can anyone explain in a step-by-step way how to batch-convert many RGB images to CMYK?
Thanks in advance

If you do want to use Photoshop for the bact conversion there are a few ways, including Batch and Image Procesor under the File>Automate or File>Scripts of PS.
However, my preference is to use Russell Brown's script: Image Processsor Pro, via Bridge:
http://www.russellbrown.com/scripts.html
As similar one is Picture Processor:
http://www.scriptsrus.talktalk.net/
Both allow you to do multiple conversions simultaneously, to different sizes and file types, and running actions before or after the conversions.

How to convert sRGB images to CMYK retaining icc profiles?

I was given the follwoing info. but not sure it answers fully - it still doesn't resolve the problem of converting to CMYK with the icc profile. I think this might be an option if the profile is loaded into the colour setting (colour settings under edit menu as oposed to convert to profile and its convert to profile I have been trying to action. Am I missing something straightforward?
thanks!
you can do batch process in Photoshop

-There is a fast and easy method to batch convert many RGB photographs to CMYK files by using Photoshop
-Please open an image, then open the Action Tab (Window > Actions)
-Please click 'Create new action' button, name the action in the text field and click the 'Record' button.
-Now it is recording, so select 'Image > Mode > CMYK Color', then hit the 'Stop' button in the Action Tab.
-The action is now created ready for the next step.
-To batch convert a folder of images, just select 'File > Automate > Batch' and the following window opens.
-Choose the 'Convert RGB to CMYK' action from the drop-down list, choose the source folder where your images are stored, then choose a destination folder where Photoshop will save the converted images.
-Click the 'OK' button and the batch process will start. How fast will depend on the number of images that need converting.
-The action you created will be stored, so you only need to perform a new batch process the next time you need to convert a batch of images.

I think we may need a little more information to fully address your question or issue. sRGB and CMYK are two very different color spaces, and converting from one to the other requires significant shifts in color. Are you refering to a specific input or output icc profile?

Why does my RAW image look grainy when I export it in to Photoshop CC from Lightroom for editing?

Why does my RAW image look grainy when I export it in to Photoshop CC from Lightroom for editing?
Checked LR's setting for Ps export and they haven't changed since it was OK a few days ago? It is OK if you zoom in but in 'fit page' it looks terrible!

I have exactly the same problem and it has got worse today as the photos also now open in smaller windows for some reason

Why does my converted raw to jpeg image have an arrow pointing to it?

When I have taken a raw image through the camera raw edit and then to full edit in elements 10 and then post the converted image onto my desk top to then move elsewhere why does it show up with an arrow pointing to the image and why am I unable to use it unless I send it to iphoto first? See screen shot of photo of woman with arrow pointing to it. What does this mean?

Presumably you have a desktop folder or desktop pictures folder. Go directly to the folder containing the jpeg.
You can set-up Elements as your external editor in iPhoto settings.

Does Lightroom 5.7 do focus or image stacking.

Does Lightroom 5.7 do focus or image stacking.

No. Use an external editor for that - e.g. Photoshop, Elements, GIMP...

'greyscale' RGB image, need to convert to specific CMYK black... how?

Hi,
I have an image provided in RGB, but visually it's greyscale, except for some red areas on certain clothing. I need to convert it to CMYK, and I want all the black areas to be 40/30/20/100, and the grey values should be percentages of this mix. The red should be visually unaltered. Im using CS3 btw.
Is there a way to quickly do this? I can convert to a generic CMYK value then tweak the curves of each channel, but it will affect the red. I could make a selection to exclude the red, but i feel there must be a way for me to define my black, and convert, and for my wishes to be granted automagically.
I tried redefining my default black in the foreground/background swatches, but that had no effect on the subsequent conversion.
Also, I'm trying to avoid profiles as my brain is foggy in that area...
Thank you,
Simon Gregory

Without seeing the image, it might be a shot in the dark, but what about creating a new CYMK document, of the same size as the RGB one. Add a layer filled with the 40/30/20/100 black.
Go to the RGB image, In the Channels panel, drag the red channel to the new channel icon. Drag this new channel to the CYMK channel panel. Add a layer mask to the 40/30... layer. go back to the channels panel, and target only the copied channel, copy it, target the layer mask channel, paste. Target the Layer mask, invert it.
Now, select and bring the red part from the RGB image, and you should be good to go...
