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.

Is there as easy way of batch converting RGB files to CMYK in OS Lion?
I was using a photoshop droplet on my desktop but this no longer works due to the fact it requires rosetta support.

From another forum after googling:
Your computer came with everything you need, because ColorSync can do that and Apple provided AppleScripts for it. Go to your Applications folder and look for the AppleScript folder. Double click on the 'Example Scripts' alias and then open the ColorSync scripts. Drag and drop your images on the the 'Match to CMYK' script.
You can open AppleScript Editor from Launchpad (it's in Utilities). Go to Help to Open Example Scripts Folder. In the ColorSync folder is a Match application. Double click to make it run.
Now you know what it does you may need to change it for batch conversion.
Go to AppleScript Editor and open what you've just found. And I'm sorry that's as far as my knowledge goes, hope some one can fill in the gaps.
Or you may just want to look at something like Graphic Converter?

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)
Regards
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.

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).

How to batch convert tiff images to jpeg in Pages document

I have a large (about 1Gig) Pages 5 Package document with hundreds of images, mostly in tiff format. Since the software became nearly unresponsive, I need to convert image files in jpeg (though I wonder why unresponsiveness in the Package mode). Reducing file size is not an option since it decreases resolution.
Is there a script, perhaps, that would convert all images in a Pages document to jpeg?

What version of Pages?
Not to my knowledge.
You may be able to create an AppleScript, a very long shot, but it will not use Pages to do the conversion and will take longer to do than simply correcting all the images and reimporting them.
Preview.app can convert from one format to another and there are Automator workflows that will convert image formats. You will lose some detail because jpegs are a lossey format whilst tiff is not. Have you looked at reserving the images as compressed tiff files?
How did you get into this position? You must have known the file would be huge with so many large images in it. Pages 5 is particularly bad, increasing file size exponentially.

How to batch convert psd to png with layers

how to batch convert psd to png with layers
i want to convert lots of PSD files into PNGs WHILE RETAINING
LAYERS!
simply batching and choosing custom setting flattens the
thing.
how do i do that!??
and i KNOW it can be done somehow - because i have some old
png's i KNOW come from the same psd source. ironic, isn't it?
besides - feature wish for adobe developers:
A) batch conversion should include 300dpi to 72dpi and vise
versa.
B) batch conversion should include PSD to PNG and vice versa
- including layers and transparency.
C) RGB to CMYK option when converting from 72 dpi to 300dpi.
D) batch exporting should include PNG32 which it doesnt now -
but somehow DOES include the outdated and stupid gif-format.
E) i'd like the Actions feature of photoshop - makes batching
complicated procedures easly.
F) I'd like support for the brushes of photoshop
G) Better selecting tools for details like hair and fine
edges.
Important notes is that i as webdesigner often need to make
certain aspects of my clients graphics into print material. Also
that i use fireworks for picture editing.
Praise for the developers of fireworks
A) the compression facility of JPGs is AWESOME!
B) PNG as fileformat is likewise awesome - i end up using it
for almost all i do these days. Transparency and good file sizes. I
have used fireworks cs3 to convert all psd and tiff and ai files to
PNG.
C) the vectors and styles and method of selecting and editing
things in fireworks is FAR SUPERIOR to flash and photoshop!

Script to convert RGB values to CMYK values

I want a script that can help me convert RGB value to CMYK values.
I've seen this thread which explains a script to round up and down:
http://forums.adobe.com/thread/1079041
but is there a script that i can actually define lets say the colour is yellow and in RGB it looks ok because its in RGB mode so you change it to CMYK and you have 6% - 9% cyan and you only want yellow
is there a script out there that i can say
if
cyan = 6%
yellow = 80%
magenta = 0%
black = 0%
then change to
cyan = 0%
yellow = 80&
mangenta = 0%
black = 0%
I don't mind writting the code for each colour that needs to be converted as it would only need defining once but how would i make this script?
any clues?

Hi Carlos,
I've got a bit further with applescript as i've used it a little but i've got an error this is my code so far:
tell application "Adobe Illustrator"
          if exists color is equal to "C=0 M=0 Y=0 K=90" then
                    set color to "C=0 M=0 Y=0 K=100"
          end if
end tell
The error i'm getting is "can't get color"
the color is there however i believe i must not be using the correct variable any clues?

Converting RGB images (sRGB or Adobe RGB) to 709 color space.

I'm trying to determine the correct way to convert RGB images (sRGB or Adobe RGB) to 709 color space. I can't just use the "covert to profile" function to do this because it does not produce results that fall within the 16 to 235 range that 709 dictates. I've read that you can simply use the "Levels" adjustment and change the output levels to 16 to 235. While this would clearly compress the luminance to the correct range, I'm not entirely clear if the end result would be a proper conversion (i.e. if color and gamma, for example, would be technically correct.)
I noticed that converting the profile to "HDTV (Rec. 709)" does alter the image, so I'm wondering what the result would be if I did both this AND used the levels control to compress the output range to 16 to 235.
Thanks for any feedback on this.

(1)
http://en.wikipedia.org/wiki/Rec._709
(2)
http://en.wikipedia.org/wiki/Rec._601
The transfer functions for Rec.709 (1) refer to the range [0..1] or for 8 bits per pixel [0...255].
It seems that the clipping, black=16 and white=235 has to happen after the application of the
transfer function. If this should be true, then we don't have a level compression but a level
clipping at both ends, as already for Rec.601 (2), like here:
The ICC-Profile HDTV(Rec.709) in Photoshop contains the primaries and the white point
(both like that in sRGB) and the transfer functions for [0..1], coded by a LUT with high resolution,
as found by Profile Inspector. There is no clipping.
By the way, that`s the internal profile name, I don't know the file name of the profile.
Softproofing, source in sRGB, target HDTV(Rec.709), without clipping:
With numbers not preserved: no change of the appearance, as expected.
With numbers preserved: shows the effect of different effective gammas.
Your questions are very clear and I'm not sure whether my comments help. The information
in the internet is not convincing.

How do i convert an image object to a byte array ?

Hi
how do i convert an image object into a byte array
early reply apperciated

Oh sorry my method and the other method need to have the pixels from the Image passed to them which you get my using pixelgrabber:
//create width and height variables from image
          int w = img.getWidth(this);
          int h = img.getHeight(this);
          //retrive picture from image
          int[] pix = new int[w * h];
          PixelGrabber pg = new PixelGrabber(img, 0, 0, w, h, pix, 0, w);
          try{ pg.grabPixels();
          } catch (InterruptedException ioe) {
               System.err.println("Interrupted");
          if ((pg.getStatus() & ImageObserver.ABORT) != 0) {
          System.err.println("image fetch aborted or errored");
          }

How do I convert raw images with side car to Dng and

How do I convert raw images with side car to Dng and preserve the sidecar info in the DNG?
I have tons of raws + xmp sidecars that i want to convert to dng, because the raws are from different camera brands and i want to get everything simplified. so that i do not have to worry if I will be able to access the raws in the future, if I decide I want to rework some of the files.
T.I.A.

If the images are already in your catalog you can select them then choose Convert Photos to DNG from the Library menu. You'll be given the option of deleting the original raw files. Either way, Lr will only display the newly created DNG files.
The alternative, which is better suited to images not already in the catalog is to use the Adobe DNG Converter

How do I convert all RGB images to CMYK for PACKAGING - InDesign CC?

I understand that they can be exported as a CMYK pdf - but I'm splitting a project with another designer and she needs to get me all of her files - many of which are RGB - need them CMYK. Thanks!

You can't convert the color mode of links during packaging -- and you don't need to, most likely. Why do you think you must have CMYK? Unless you know the correct output space now, and have no plans to re-purpose the file in the future (and even if those things are true and you don't need to make post conversion adjustments to the color) there is no advantage, and plenty of disadvantage, to converting to CMYK before export.

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!

-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?

How can I package my InDesign file without converting the images to CMYK?

I had previously thought I have to convert each link individually, but I have received packaged files that include both RGB and CMYK images, but when I try to package my document, it is saying that I have errors on all the RGB images. Are there settings that allow me to package the links without conversion? I know how to export it with a one-time conversion, but I cannot find the answer to this question anywhere.

Thank you for helping! I must be doing something else wrong then because it will stop packaging as soon as it tries to get the links... and will gather a few and then stop. The warning message is "could not copy linked files" but I don't have any warning signs on any of my links in the links panel...
