Re: Generate CMYK tif image from C, M, Y, K tif images

Hey guys, I think I found a solution by myself. I´ve been watching the examples here http://www.imagemagick.org/Usage/color_basics/#combine_other , and I have realized that in separated images, white color means there is "a lot" of the corresponding color. For example, in the separated image for ...

The results have ...

Generate CMYK tif image from C, M, Y, K tif images

Hi guys, I have 4 1-bit tif images ( one tif for each color CMYK), and I would like to combine them to get one tif with all CMYK colors. How can I get this? I used CopyMagenta, CopyYellow and CopyBlack, but it didn´t work fine, because black color seems not to be copied. I´m using ImageMagick 6.8.4-1 ...

Re: CMYK TIFF to LAB TIFF convertion

Hi again. Sorry, I forgot to mention that the CMYK values before converting to myProfile.icc(ISOnewspaper26v4.icc) are: "# ImageMagick pixel enumeration: 1,1,255,cmyk 0,0: ( 3,253,178, 12) #03FDB20C cmyk(0, 255,255,0)". CMYK values after converting to myProfile.icc are: "# ImageMagick pixel ...

Hello guys. First of all, thank you for your fast replys, Snibgo. I did what you said in your last post (create an 1x1 image, applying USWebUncoated.icc and then converting to myProfile.icc). And you are right, I see changes inc CMYK colorspace values in the new image after USWebUncoated and ...

Re: CMYK TIFF to LAB TIFF convertion

Thank you very much again for your fast reply, Snibgo. Well, when I say "passing through" the icc profile, I mean "converting". I did what you say: convert /myPath/myCMYKImage.tif[1x1+0+0] txt: before applying USWebCoatedSWOP.icc and then converting to myProfile.icc and the result is "# ImageMagick ...

Re: CMYK TIFF to LAB TIFF convertion

Thanks for your fast reply, Snibgo. Yes, you are right, I want to convert to "myProfile.icc". The original image "myCMYKimage.tif" has no profile. I did exactly what you say (applying USWebCoatedSWOP.icc and then converting to myProfile.icc): convert -verbose myCMYKImage.tif -profile USWebCoatedSWOP ...

Re: CMYK TIFF to LAB TIFF convertion

Hi guys, I´m brand new in ImageMagick, so maybe I loosing something, but I still cannot be able to convert correctly a CMYK tif file into a LAB tif file. Let me explain my case: 1- I receive a CMYK image (1x1), with C = 0, M = 100%, Y = 100%, K = 0 (its LAB is "cielab(53.2311%,80.708%,74.3816%)") 2- ...
