Actions: How can I change colors automatically

[jdh_gd]

Hi there,
I would like to change QR-codes automatically, which are unfortunately only available in RGB-mode, to only black 100 in CMYK-mode and adjust the drawing area to the size of the QR-code.
To do this, I created an action that first converts the Code from RGB to CMYK. Here Illustrator creates the CMYK colors C = 90 M = 83 Y = 96 K = 84 from R = 0 G = 0 B = 0. In order to only expose the black film in the print I need C = 0 M = 0 Y = 0 K = 100.
Unfortunately I can't get this color to be converted automatically.
What should an action look like that converts the color from RGB to CMYK, then the CMYK color to C = 0 M = 0 Y = 0 K = 100 and then adjusts the drawing area to the graphic?
Thank you for your help

That's certainly doable with a simple action.

Can you perhaps share a sample Illustrator file, so one can have a look at it?

Hi Kurt,

I hope so. ;o))

I am looking forward to your solution.

Based on your sample file you may try this one.

QR-Code-Black-Maker

Instruction:

- Download and unzip the action set file.
- Load it into the Actions palette.
- Open a document and run the action.

I would do it slightly different and skip one convert to CMYK step.

Select All

Edit > Edit Colors > Convert to Grayscale

File > Document Color Mode > CMYK Color

Object > Artboards > Fit to Selected Art

Deselect

Perfect, thats it.

Thank you very much!

The second Convert to CMYK step is just meant as a gentlemen's gift to get four sliders in the Colour palette, Ton.

Basically it's not necessary at all, of course.

You are a gentleman, Kurt 🙂
