Exporting an image as a TIFF with CMYK and LZW compression.

[Paul Buttrill]

I'm trying to export an image as a TIFF with CMYK and LZW compression but it doesn't seem to be working.

1. I checked 'Document setup' colour format was set to CMYK/8.

2. 'Export' as a TIFF.

3. Clicked the 'More' button and changed the 'Pixel format' to CMYK 8-bit and 'Compression' to LZW.

4. When I checked the exported file it says the colour representation is 'Uncalibrated'.

I don't know what I've missed or have done wrong while exporting.

Have you tried checking in something else? File Properties in Windows may not be a reliable source of information/properties.

Hi @Paul Buttrill welcome to the forums,

As Psenda mentioned, Windows Properties isn't a particularly reliable method of identifying image metadata such as Colour space, according to some sources online, this will typically default to uncalibrated in Properties if it isn't sRGB.

The CMYK profile is being embedded in the TIFF even with LZW compression which I confirmed via Apple Preview.

That's great. Thanks. In future how could I check the properties other than using Windows properties?

XnViewMP (ExifTool) can do this.

[N.P.M.]

Try out xnviewmp https://www.xnview.com/en/
(free for personal use and has a portable version)

Brilliant. I've just downloaded and used xnviewmp. Thanks a lot.
