Illustrator :: How To Convert Colors From RGB To CMYK
Jan 21, 2014
I always find beautiful RGB-vectors which I want to use for a print design. But once converted via Illustrator to CMYK, the image often annoys me because of the less bright and powerful colours.
So: what is the best way to recolor a nice and colourful vector from RGB tot CMYK (possibly with finding the right alternative colors in CMYK?) in Illustrator?
I'm having an issue where I can't convert spot colors to CMYK in the swatches panel. Currently to fix I have to copy elements using the spot colors in to a new blank document, then convert them, then paste back into the original document.
Also if I try to delete the spot color, it doesn't fully delete the swatch.
I've been having this issue with InDesign CC lately, its importing some of my pantone colors as LAB colors. I am able to change a spot to process, but as far as changing the LAB color to a CMYK color, the box is grayed out and is not giving me an option to do it. See screenshot: [URL]....
Using CS6 on a MacBookPro Is there a way to find the closest matching Pantone spot colors to the cmyk colors I've created in Illustrator? I know it's easy in Photoshop using the color picker, but there must be a way to do this in Illustrator.
I have recently traced a new picture and I am about to add colors to it so that I can upload it later on my gallery. I started the Tracing on a Cmyk based template because one day I will use print it to add it to my portfolio! I mean should I add Cmyk colors and them convert them to rgb in order to upload it?
I'm still using CS3. A friend sent me a document created in CS6 (I think) that he saved as a CS3 document. When I open this blank document he sent me, and then copy and paste a CMYK object from my CS3 original to his blank CS6 (saved as CS3), the object changes color quite noticeably (darker). The CMYK values are identical, but they don't look anything alike. On the left is a screen grab from my original CS3 document, and next to it a screen grab after I've copied and pasted the exact same objects into the CS6 created document. The CMYK values are identical in both, and they're being displayed on the same computer on the same monitor.
I'm moving art over to a new document. It was created in CMYK. The new document has a color mode of Basic RGB. After pasting the art I select it all, and choose Edit | Edit Colors | Convert to RGB. After saving and re-opening the document, the art once again has CMYK attributes, not RGB. What am I doing wrong?
I've recently upgraded to CS6 and also to OS 10.8... Im working in multiple Illustrator docs using a color of 100-87-32-32. When I change objects to that color by keying it in to the color pallete, it changes. If I click off, go away and come back the color shifts to 100-82-36-29 or something similar.
I have been trying to convert both Pantone Colors to CMYK and CMYK to Pantones on a few of my projects. I walk throught the steps but nothing happens. My counterpart which has CS5.5 also is able to do it both ways just fine. Is there a pre-set someplace that I need to be aware of?
I work in prepress. I have an Illustrator CS6 file that is made up of 3 Pantone Spot colors. I save the file as an eps from Illustrator and rip the file with our prepress software. When previewing the ripped file with our prepress software it shows me that I have process colors (CMYK) somewhere in the file. I can not see these colors visually in the ripped file so I go back to Illustrator to see if I can edit them out of the file. I use the Preview Separations tool but can't find those process colors anywhere. There are no placed images, everything is vector art. I double check any white color and make sure it doesn't have any tiny percentage of process color in it. I make sure my spot colors are indeed spot colors and not process colors. I add used colors, I delete unused colors. I can't find the CMYK being used anywhere in my Illustrator file. How to clean up these "hidden" colors? This was also a problem in CS3. I'm using an iMac 2.5 GHz Intel Core i5, Mac OS X, Version 10.7.5
I need to convert a bunch of vector artwork for a brand I made from CMYK to RGB.
But, illustrator won't give me the option to do so.
I upgraded from CS6 to CC, but am still having the same issue. It's all vector right now.
Manually changing each colour will take hours, as there's many files and gradients. So, I'd love to just be able to use Illustrator's build in feature.
But, here's what I get. Convert to RGB is in light grey and I can't select it (click on image to see better):
I've designed a logo for a client using Illustrator CS6. There is the 4-color version in CMYK .eps as well as 1-color, 2-color, and KO versions. Everything looks and acts as it should and will no doubt be perfect for offset printing (my main area of experience). However, once delivered to the client they were anxious to put them into use and immediately dropped the 4-color version into a word document and made a pdf for email distribution. When I received it I had to groan, the colors had shifted to the obscene.
My guess is that what the client needs is a set of the logos that are converted to RGB. I'm also thinking that since the logos might be re-sized for various uses, keeping the art in the .eps format (as opposed to a raster format) makes sense. Is that true?
Is there an easy way to convert the original CMYK eps files to RGB within Illustrator?
Have an illustrator cs6 file I just sent to a client for printing. It has linked rgb and CMYK files. When I sent the file I forgot to convert the rgb images to CMYK. They were linked psd and tiff files. Don't have direct contact with who will print. Do I need to worry about the RGB images outputting poorly? Or will Illustrator handle the conversion ok just in case printer doesn't check the files carefully.
I am working in Adobe Illustrator CS6 and InDesign CS6.
When I create a swatch using Pantone colour books (solid coated) and then convert the swatch to CMYK the values differ between programs and also differ to my hard copy of Pantone Colour Bridge.
I have followed the Workaround 1 on [URL]...which was useful - now the CMYK values produced in Illustrator and InDesign match HOWEVER they still differ from my hard copy of Pantone Colour Bridge.
I copied the leagacy files from CS4 - is it possible the CMYK values embedded in these files are out of date or is it possible that the CMYK values in the Colour Bridge book have since changed?
I want a script that can convert RGB value to CMYK values.
I've seen this thread which explains a script to round up and down:
[URL].....
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?
Currently, i receive artwork in CMYK but i need to resubmit to painter using Pantone.? i have installed Illustrator CS6 recently and not familar with the software.
I have over 900 barcodes provided in EPS format. When I open them in illustrator, they are coming in as an RGB color space file. I need them gray scale solid black in CMYK color mode. I can batch using actions to convert the artwork using "Edit Colors > Convert to Grayscale". However, the document color mode remains RGB. It appears, even after using "Convert to Grayscale", that the RGB color mode goofs up the placed .ai file in InDesign, treating it as RGB and seeing it as a mix of CMYK rather than the 100% black only it needs to be for proper sharp printing.
The actions pallet doesn't record converting the document color mode. Is there a way to automate that file conversion so they are all saved as CMYK rather than RGB, or am I stuck opening each of the 900+ files manually?
I'm pretty new to preparing artwork for spot colour printing - it's a hoodie design in this case.
I created the artwork in CMYK originally, and have got some of the way towards converting into a 5 colour print job using Recolor Artwork, so I've got it down to 5 swatches.
However, the printer is asking for colours separated by layers, which makes sense - I think means knocking everything out so there is no overprinting - is this correct?
If so, what is the best approach to take, to avoid unnecessary work, to convert from the current artowrk, with a lot of overlapping artwork, to produce 5 layers each with vector artwork coloured with its own Pantone swatch?
I work with a large number of Illustrator files daily that all use the Pantone Solid Coated library for their swatch color scheme. This color library will be used whether customers provide the art pieces or if I design the pieces for them.
However, I have found that in order to best match our digital press we must to convert the inks to the Pantone Color Bridge CMYK PC library before printing.
Basically the same color number just the different library (eg PMS 200C would convert to PMS 200PC if outputing in-house to the digital press).
My question - is it possible to create a script that would swap out all the colors in a document (that are in a specific library) with the same colors from a different library?
*More specifically what I am wanting to do is if I have a document that has a dozen solid coated colors swap them for their same numerical equivelant in the Color Bridge CMYK PC library.
Alright, I have a grunge vector I'm using in an opacity mask over my shapes. I need to convert my .eps grunge vector to full black, if I dont then the end result looks fine in illustrator...but when brought into PS you can still see light pieces of the object that the grunge was supposed to mask out.
When I click the eps file and use %100 black: instead of filling the grunge bits to black, it fills the entire selection black so I end up with a big black box, and if I use the stroke, it outlines the box itself. I tried making a compound path and also expanding the grunge, then retrying but no dice. Does AI recognize this eps file as one big square selection?
How do I get my .eps grunge vector %100 black rather than the CMYK black?
So I've been having this issue with Photoshop ever since I started using it on my Windows machine. On my Mac. I could set something to any color and it would appear that way on the screen in RGB mode. However, when I try and do that with the same exact color on my Windows machine it appears in black. I don't have Gamut Warnings on either. However, when I switch the mode to CMYK the color appears. The problem with this is I use photoshop for GUI's and such, not print materiel so if I have it show in CMYK Mode it will give me an inacurate look at how the colors will look.
In the color picker, if I enter R255-G80-B0, the CMYK color reads M83-Y100. However, if I instead enter the M83-Y100 in CMYK first, then the RBG numbers are R240-G83-B35, and if I enter these numbers first, then the CMYK numbers change again.
Why is this happening? Shouldn't the RBG translate to to just one CMYK color and vis versa?
