: How to batch convert RGB to CMYK and have black mapped to 0%C, 0%M, 0%Y, 100%K (NOT rich black!) I have several SVG files (generated by a JavaScript framework) that need to end up as CMYK

Posted in: #AdobeIllustrator #Cmyk #ColorConversion

I have several SVG files (generated by a JavaScript framework) that need to end up as CMYK .EPS files for print.

So I made an action for it, changing the document color mode to CMYK, assigning a CMYK profile, flattening etc.



I want the RGB blacks to become 100%K in CMYK. It's 83%C 79%M 73%Y 95%K now.

I looked in Edit > Preferences > Appearance of Black... and set it to Output All Blacks Accurately



I wouldn't like to do it manually for every file, is there a way to interpret RGB black as 100%K by default?

I'd record a script that goes:
1. Click on a rich black object, Select: Same Fill Colour
2. Have a 100K swatch ready, select it to fill all the rich blacks with 100K
3. Save
4. Close

If in RGB,
1. Select all
2. Convert to RGB colour space (may have to insert this menu item after recording)
3. Follow 1-4 as above.

I haven't figured out any other way than with scripting.

Here's the script:

Flatten Black - Illustrator script to batch convert rich blacks to 100%K

To use inside an action insert it with Insert Menu Item. It works by scanning through your CMYK artwork looking for fill or stroke colors that have a more than 95% black and 300% coverage (you can set this at the top of the script). Those colors it mercilessly changes to 0%C, 0%M, 0%Y, 100%K - flat aka pure black.

I'd love to hear an alternative answer as I feel this is a pretty basic feature that I expected Illustrator to have. Please also share how this is achieved in competing software (Corel, Inkscape etc.)
