Re: Trying to merge print TIF files results in weird colors & other problems

Okay, I found the villain. It was the `smush` command. This results in an image with broken colors: magick *.tif +smush 700 result.tif While this works fine: magick *.tif -splice 700x0+0+0 +append -chop 700x0+0+0 result.tif It seems like when using smush, imagemagick will generate a new image canvas ...

Re: Trying to merge print TIF files results in weird colors & other problems

All source TIFs should not have an embedded profile. I was just playing around - the SWOP profile is the one my printing agency is using, but we can leave it out for now.

The version is 7.0.8-66 Q16 x64 on Windows 10. I seem to come closer to my desired result with this command - at least in the windows preview + IrfanView, it looks okay now. Photoshop still refuses to open the result file. magick *.tif -background white +smush 700 -profile "./USWebCoatedSWOP.icc ...

Trying to merge print TIF files results in weird colors & other problems

Hey, I am trying to merge three TIF files with CMYK colors into one. This is the command I used: magick *.tif -background white +smush 700 ./combined.tif This is the result: https://dl.dropboxusercontent.com/s/nnk8efda3j025f2/shot_190925_120902.png Somehow, the colorspace gets messed up. I tried ...
