Michel, I think this is a true tribute to a legend like Jongware. Your tribute portrays that both InDesign and Jongware are made for each other where one is the soul and the other is the body. My sincere respects to you.

Thanks, David for making me part of this tribute.

Hi David, Hi jongware,

Hope you are well.

Really sorry for reopening this topic. A few days back, a friend of my colleague who is currently working in Dubai, asked the same question. I told him that it is not possible. Out of curiosity I then searched the web and tries to achieve this, but no luck.

I also tries my hand on the PDF (https://creativepro.com/creating-custom-printer-marks-in-indesign/) but didn’t get anything that could change the color of the cropMarks.

I know we can add cropMarks manually using the slug area, but I’m now more interested in some code that can change the color of the crop marks.

After reading the PDF, I see that we can change the color of the text, text bar, strokes etc, then why are we not able to change the color of the cropMarks.

I’m sure, Jongware can do some magic here.

Looking forward to…

Thanks,
Masood

You can try this one liner to change the Transparency Blend mode to RGB

app.documents[0].transparencyPreferences.blendingSpace = BlendingSpace.RGB;

save this code as a ‘[name].jsx’ JavaScript file and run it using the batch export utility on the folder containing your 40 files.

Hope this will help.

Hi Darrel,

I’m not sure, if converting to dotGain using Convert Colors is part of your process, but to my experience, it will definitely add a slight dot gain every time you convert your document. If you ask me, I would prefer to use the preflight fix –– “Convert color to B/W”. This preflight profile is purely based on 15% dotGain. Your gray tones will remains the same even after adding a color page to the pdf and re-preflighting it. Just give it a try.

Thanks,
Masood
