CMYK colors are washed out

[itsnotyouitsme]

Hi, I am attempting to create TIFF images using the CMYK colorspace however the colors always appear washed out (significantly lighter) when previewed in Photoshop (or any other app).

The command I'm using is:

Code: Select all

convert -units PixelsPerInch -density 300x300 -channel CMYK -colorspace CMYK -background none -fill cmyk(0,99,100,0) -depth 16 -font fonts/century_gothic.ttf -pointsize 15 -size 250x -gravity NorthWest +antialias caption:\"This is just a little sample to text to help make the point!\" -trim +repage temp/output.tiff

I suspect it has something to do with "profiles" however I'm very new to ImageMagick and can't seem to make sense of how they work.

Any assistance would be greatly appreciated.

Enjoy...

Problem solved - turns out I needed to set the CMYK values as percentages rather than integers. eg cmyk(0,99,100,0) became cmyk(0%,99%,100%,0%).

All colors now display as expected.

(I also added the profile - USWebCoatedSWOP.icc)

Enjoy...
