Rgb to cmyk on indesign

my document is in cmyk but when i want to select a colour it only allows me to select rgb colours, how can i change my colour remetrix space in cmyk
thank you

With the Color panel active, click on the small triangle in the upper right to reveal the Options. Make sure that the CMYK line is checked like this

Change RGB to CMYK in InDesign CC

I can't find the option in the swatch panel anymore. How can I change the colors to CMYK?

The option is still there in the same place, it's just when you click on the swatch options and go to colour mode RGB looks as though it's sitting at the top of the pallette, however you just need to scroll up to reveal the other colour options

Why do the relative values of RGB and CMYK change when switching between Photoshop and InDesign?

I'm trying to put together a Colour Guide for my company's brand guidelines.
I initially worked from InDesign and wrote down all the H, RGB, and CMYK values that I got when I eye-dropped my original colour palette.
However when I put the same RGB values into Photoshop- I am given a (slightly) different set of CMYK numbers from those that I had originally documented in InDesign.
Why is this???

Jamie,
in Photoshop go to Edit > Color Settings and choose your parameters:
For RGB: sRGB or AdobeRGB (1998)
For CMYK: the process as recommended by your printer (person, company)
For offset printing this is here ISOCoated-v2-eci and elsewhere for instance SWOP.
For digital printing you should ask the company as well.
For Grayscale: Gray Gamma 2.2
For Spot: probably irrelevant in the moment. Dot Gain 20%
Everything as shown here:
For your application I've modified my settings a little, therefore we can see top left 'unsynchronized'.
In InDesign do practically the same, but there are no settings for Grayscale.
You'll find for any topic explanations if you move to by mouse (position the pointer over ...).
The field 'Settings' shows not 'Custom' but the file name of a configuration which had been previously saved
and then loaded (buttons top right).
Further explanations on request. It would be quite useless to explain everything now at the same time.
The colors will be wrong if the settings are not synchronized. Above they are explicitly synchronized.
Because Bridge was not used, the system considers them as 'not synchronized', which doesn't matter.

RGB to CMYK to commercial printer

We are using CS2 InDesign and Photoshop 7 on a PC. I am putting together two
large books. One insert section of the first book has color photos. I have
to prepare these color photos for a printer located in China. They want all
images to be CMYK .tiff.
I have an assortment of about 100 images from various sources around the
world, there are .tif, .jpg. .bmp, and .psd. All of them appear to be RGB.
There are images with: 1) no color profile, 2) sRGB IE60966-2.1, and Adobe
RGB 1998. Do all images need to have the same RGB color profile before
converting to CMYK?
I have been converting all of these to .tif (and using a single dpi/pixel
resolution for
all images).
Do I just select/save as color mode CMYK? Or are there special
settings/profiles I need to know about. Is there anything special for China?
The printer's English is not that clear . I was hoping that someone in this
group would be familiar with RGB to CMYK conversion.
Also, it appears that the final PDF pages (with embedded Tiff images) will
be very large. The first complete book for this project (there are two
books) looks like it will be about 20GB. The second book looks like it could
be 12GB. Both books together equal about 1,000 pages and have about 1,000
images. 90% of the images are grayscale. What are the current technologies
for sending large projects like this to a printer?
Thanks
ps, the Photoshop group suggested that I write to this group.

Tech....
In the conversions, are you referring to conversions of B&W or color images? I'll assume color for the moment.
Assuming your monitor is properly calibrated, and assuming you are viewing your color images on your monitor, your conversions should keep "in gamut" colors the same. You will, however, probably see some loss of dynamic range, color, and saturation as you enter CMYK. If the color and dynamic range of the original is all within the destination CMYK gamut, you should see very little, if any, shift. The sad fact is that CMYK on press has limited dynamic range and color, especially compared to a bright monitor. This is generally true, though CMYK can print some colors that lie outside the typical monitor's gamut.
If you have a brightly colored original in RGB mode, then you should experiment with both perceptual and relative colorimetric rendering to see which one looks best. This is an image by image thing. Relative colorimetric will reproduce all "in gamut colors" as accurately as possible, then will take out of gamut colors and bring them to the closest printable color. This can cause loss of detail and 'piling up of colors' as you near the boundaries of the image's color gamut in the destination CMYK space. Perceptual scales ALL colors and preserves the relationships between colors, which sacrifices color accuracy and saturation, but sometimes looks more natural, especially if there are a LOT of out of gamut colors. Pick whichever ones looks best overall.
Then, once in CMYK, make minor curves adjustments to tweak if for CMYK. Just be careful not to push it too far, especially in the deep shadows, since you may push beyond the ink limit of the press. For example, if you convert to US Web Coated SWOP v2, the ink limits are set at 300 total. If you drastically darken the shadow areas, you could end up with an ink limit of 320, 330, 350, etc. Knowing the ink limit of the press will help you stay within those limits. Final tweaking in CMYK is usually a good thing.
How did you determine that the images were dull with too much magenta? Did you print a proof on a calibrated printer, or is this just your screen display? Or is this from a printed image off the press? I have a well calibrated monitor and accurate custom profiles for my inkjet. If I am sending a job to a press that supposedly prints to US Web Coated SWOP, I can proof that file on my inkjet and get a very good match. We need more information to know exactly what you are doing and how you are assessing your images.
Normally, I do the conversion in Photoshop, using the rendering intent that looks best. Then I tweak the image in CMYK to get it looking its best. I usually have the press profile, but sometimes work with a standard profile if no custom profile is available. I leave the image tagged with my conversion profile. Then, I usually place these images into InDesign, with the profile intact (color management turned on in InDesign). I right click on the placed image to be sure that the profile and rendering intent are set to what I want. Then, I can either supply the InDesign file to the printer, or convert to PDF (leave color unchanged) and make sure that all profiles are included. InDesign should export each image to the PDF properly, along with profile and intent. I have never sent to job to press using Photoshop...only InDesign or Illustrator.
BTW, rendering intent is only used when getting an image from one color space to another, such as a conversion from RGB to CMYK. You do that, choosing the one that looks the best. Once it is in the destination CMYK space, rendering intent is no longer needed, since all the colors and tones have already been remapped into the final space. Rendering intent is just used to help us handle those out of gamut colors.
Hope this helps.

How to make a script to convert RGB to CMYK as black 100%?

Hi guy
my customer sent me a book (144 pages) for print but all of them are RGB and Tiff, she scan them. there are on the page some texts and pictures. The text are R=30 G=30 B=30.I think if I can make a script I will do it very soon to black 100%, but unfortunately I dont know anything to make script
anybody can help me ?anybody can make it for me ?

We need to know some more information.
1. The book consists of 144 pages, and each page is in fact an RGB image in TIFF format.
    Correct?
    That means, the text is already rasterized, but with low resolution (no more than 300ppi).
    A very bad starting point, in my humble opinion. For offset printing this is not acceptable.
2. Is the printing process offset printing or by digital printing?
Nevertheless we may think about a conversion of these images into CMYK K-only (one plate
per page) .
a) Increase contrast until R=G=B=0 for text.
b) Convert each image into Grayscale, using a so-called Black-Ink-Profile, for instance
    Black-Ink-ISOCoated-v2-eci (can be explained later)
c) Make empty CMYK image, here for ISOCoated-v2-eci, and paste the Grayscale into the
    K-channel. All further handling happens as CMYK file for the process ISOCoated-v2-eci.
    Void plates CMY don't matter.
    Post #12 here:
    Re: Colour shift (from CMYK = 0 0 0 20 to Grayscale K = 22 !)
All this can be done by an action (I hope so...).
Much better would be a new start by InDesign with typographical text (K-only vector instead of raster)
with images in RGB or CMYK, taking into account the intended process.
Note: Photoshop can deliver vector text, if exported as PDF.

Once again: RGB to CMYK using Acrobat?

I received a lot of photographs in RGB (my color space for RGB is default to preserves embedded profiles) and make a proof in IDCS4:
1) I converted that batch to CMYK using PDFX-1a/2001
2) I converted to CMYK in Photoshop and later distilled
And the result is different. More darker photographs were obtained with the first step. Blacks were different.
How to avoid the previous conversion in Photoshop and obtain better results (or those obtained in step 2) directly with Acrobat?

I'm a little confused here. With 1, you placed all RGB into InDesign, then exported PDF/X-1a from InDesign. With 2, you converted in Photoshop, placed in InDesign, output post script and distilled. Is that correct?
Neither one involved an Acrobat color conversion. 1, the conversion is done by InDesign. 2, the conversion is done in Photoshop.
Ideally, 1 is the best option. Place all RGB images into InDesign. Output PDF/X-1a, you end up with a CMYK PDF.
To ensure you achieve the same conversion that way that you would have in Photoshop, first go to Edit: Color Settings in Photoshop. Make sure Preserve Embedded profiles is on, and note the CMYK working space. The behavior should be (if you were to do the conversion in Photoshop): open the RGB, preserving the embedded profile. Mode: CMYK will move the image to your working CMYK color space.
Now go to InDesign. Open the document in question. Edit: Assign profiles, and note the RGB and CMYK. Make sure the CMYK matches what you saw in Photoshop.
Now go to the Links panel. Check the ICC profiles for the placed RGB. None of them should say Document RGB, let me know if they do.
Now when you export PDF/X-1a, in the destination color select Document CMYK. The conversion should match what you would get in Photoshop.

Best Practice RGB to CMYK ?

Can some of you guys that work with print, point me at a decent link for a best practice workflow going from RGB to CMYK? This is for outputting a large graphic that contains a number of RGB colour photographs, for imput into Indesign, and export to PDF for print in a newspaper advert. I have the paper's requirements. The job in question is not colour critical, but I would like to feel better informed.

Trevor,
CMYK is a darned narrow color mode, even narrower than the sRGB profile.
Of course you're bound to see some of your RGB colors just die in your image during the conversion. That is the nature of the beast, and that's where soft-proofing with the target profile comes to the rescue, partially, by letting you fine tune the colors to compensate (somewhat).
Just look at all those greens, blues and reds outside of the CMYK spectrum.

Eyedropper tool RGB and CMYK help!

When I try and sample a color from a graphic imported with the eyedropper tool, it automatically creates the swatch as RGB. The imported graphic is CMYK and the document color mode is CMYK. The InDesign file is set for Print.
Please help. I hate having to select a swatch and then have to change it to CMYK every time!

For placed ai and pdf files the preview proxy is always RGB so the eyedropper gets RGB values. With image files the eyedropper will return the actual pixel color. If you are trying to get an exact match to the placed vector file's CMYK values, converting the proxy RGB values to CMYK won't work because the color will be a color managed conversion from RGB to CMYK.

Specific Colour changing Script from RGB to CMYK

I need to change the RGB values (imported from word) to specific CMYK values in Indesign (its not a straight swop) so I need a script or a similar plug-in that enables me to input the colour values for the CMYK so they automatically change.... the doc i work on is huge and im importing from a word file many times so i need to save time!!
Can anyone help me?
Thank you!

Hi Phil... Hmmm not sure if i explained myself! Or maybe I am being thick.... I tried the new code but im not sure I was clear on my problem?
This is the current code i use to change the RGN values to the CMYK is: I have entered the RGB and CMYK values as they need to be changed and it works but the swatch pallette ends up looking messy! See below.

Kann man mehrere Grafiken in einem Indesigndokument mit einem Klick von RGB nach CMYK umwandeln?

Hallo zusammen,
ich habe mehrere RGB Grafiken in einem Indesign Dokument (Indesign CS6) und möchte die gern alle von RGB nach CMYK umwandeln. Muß ich die alle einzeln in Photoshop öffnen und einzeln umwandeln oder gibt es einen Befehl, der diese alle direkt in PS öffnet und sie direkt alle in CMYK umwandelt? Oder geht es vielleicht sogar in Indesign selbst? Ich möchte dieses Dokument im Anschluss als PDF exportieren. Geht es vielleicht auch bei diesem Schritt?
Herzlichen Dank für eine Hilfe.

Some of the PDF presets, especially, PDF/X-1a, automatically convert RGB images to CMYK. Look at the Output panel when you choose PDF/X-1a.

Need Info on RGB to CMYK

Hi,
I am new to Illustrator (CS5) and not fully comfortable with RGB vs CMYK. For instance, I created a logo for use on the web using Document Color Mode: RGB where my background color in RGB is 0, 0, 130. When I create a Print document using Document Color Mode: CMYK and copy the logo into the print document, it converts that background color to CMYK (C:100, M:98, Y:16 K:18) where the RGB is now (44, 45, 111).
Is there a way to get a closer match to the original RGB color 0, 0, 130? When the specifications for the print advertisement says images must be in CMYK, I hope I am accomplishing this by using the Print Document Color Mode of CMYK vs RGB? I feel somewhat ignorant on utilizing the RGB vs CMYK color modes and if anyone can give me a tip on what techniques they use to get a closer match of colors for RGB to CMYK or vice versa, I would love to hear it.
Thank you,
Keith

Keith,
First, be aware that you have posted to the Photoshop forum, not the Illustrator forum. The general concepts of color and color management are the same across the spectrum of digital imaging. However, its implementation is slightly different from application to application, so you may also want to post your question to the Illlustrator forum.
[EDIT: Brain fart on my part... This is the color management forum, NOT the Photoshop forum, so you are in the right place! (I spend most of my time in the Photoshop forum; I lost track of where I was...)]
That said, you're running up against a general concept: color gamut.
The color you've spec'd in your RGB file (0/0/130 - and we'll assume for now that it's in the sRGB color space) is outside the gamut of every CMYK color space. That means that the RGB color you see can not be reproduced using a mix of the four CMYK process colors (cyan, magenta, yellow, black). When converting to CMYK, the software picks the closest color that is within the gamut of the CMYK space, hence the color shift.
When you're designing for CMYK, it's best to work in soft-proof mode which allows you to see a pretty close approximation of what your colors will look like in the final color output space - in your case, CMYK.
In Photoshop, to turn on soft-proof, go to View > Proof Setup> Custom... and choose the CMYK output space that matches the press conditions you are designing for.
There are books written about this, but hopefully this short answer points you in the right direction.

I can convert almost things multiple times at the same time including CMYK to RGB (or sRGB), but not RGB to CMYK and not brighten/contrast. How?

If you want a relevant answer you may have to elaborate on what you actually mean. Posting screenshots might help, too.
In any case multiple conversions of an image are not advisable in general.

How can I convert Pdf from RGB to CMYK, keeping font color 100% K while working in Illustrator?

How can I convert Pdf from RGB to CMYK, keeping font color 100% K while working in Illustrator?
When I try to open the document in Illustrator and I convert to CMYK the black font converts to rich black, but to set up for Offset printintg I need the text to be only in Black (100%K).
The original source of the document is a Microsoft Word file, I have converted the Word file to Pdf in order to setup for OFfset Printing.
Thanks

I have tried that way, but the downside is that the fonts are set in gray not in a 100%K, also I have to deal with other fonts that are composites and meant to stay Full Color. I could select text by text and convert to gray but, its a 64 page document and I wouldn't want to make a expensive mistake.

Rgb to cmyk

Is there a way to change the color makeup of ads from rgb to cmyk? I was not the creator of these ads for my newspaper but the printer needs me to change them and get rid of the built black. So, I guess I just need to change the black to pure black.

switch to CMYK color, add a Selective Color adjustment layer and change the Blacks
