PDF to JPG Color management

[omman95]

Hello, I have to do to convert a PDF file to jpg.

My PDF is for print, it's a 300Dpi and CMYK.

I show you the result when I open this PDF in Photoshop. I open, take the colorspace to RVB, take the size to 72Dpi and I save as a jpeg quality 12.

Photoshop use this :
* RGB : sRGB IEC61966-2.1
* CMYK Coated FOGRA27 (Iso 12647-2:2004)

Now I do this request :

Code: Select all

exec("/usr/bin/convert  convert  -verbose -colorspace RGB -resize 800 -interlace none -density 300 -quality 100  ARCHIVE/test.pdf[0]  test.jpg"); 

And result :


I test this request :

Code: Select all

exec("/usr/bin/convert  convert  -verbose -colorspace CMYK -resize 800 -interlace none -density 300 -quality 100  ARCHIVE/test.pdf[0]  test.jpg"); 

And result :



What param could be use to look like at my first Jpg?
I have to use -profil (icc) ?
I haven't a folder color in /usr/share. I have to add this folder and the profiles?

Thank a lot for your help
