Title: change pantone to CMYK value?
Post by: wonderings on January 24, 2020, 07:25:25 AM
So I am NEW NEW NEW to pitstop and enfocus, never used it before. At the new shop we have 2019.

I have an old business card file we used to print 2 colour on press and thermograve. We do not thermograve at the new shop and will be printing it on our Indigo. I do not think the red will match and want to be able to make adjustments to the file. With Pitstop Pro 2019 how do I select the Red (Pantone 032) and replace all instances of that pantone with a CMYK value?


Thanks

Congratulations! You will thank God for pitstop!!

I'll let some of the smarter members guide you through, I know how to do it but do not communicate that well! It's not brain surgery!

Using "Global Changes". Select an object with that color. In Global Changes open the Standard ===> Color folder and double click "Change Specific Color". In the box that pops up click the eyedropper that opens the menu and select either Grab Fill or Grab Stroke, whichever applies here, and then in lower area of the box change the "To:" to whatever color space you desire. You can either type in specific values or you can use the eyedropper dropdown and use it to grab a stroke or fill of object or you can use the color palette icon to change to a color in your library, Pantones or colors you have added to the library. Then click the Run or Save button. Either will save those values in that Global Change but it will only do the correction if you click the Run button. Once you make a global change you can right click on it and save it as separate global change or action list. IN the global changes panel you can also have it run on a range of pages, the current page, the current document, or on just a selection. (all pages or just even pages or odd pages)

If "show result" is set to Always it will pop up a panel telling you the results of the correction and setting it to Never will not show that panel.

This tool is also handy for changing RGB "black" or registration type to 100% K

Thanks for the replies. I did figure out on my own how to change the pantone to a CMYK. It was not able to do everything though. There is one image that is all pixelated and might have been made through photoshop or corel years ago. It is black and pantone, that image did not change. Is Pitstop limited to changing vector images in this regard?

Yup, Joe is one of the smarter members!

Yes that tool is for vector color
you can change images to process with pitstop, I would make sure they are not .jpg compressed first
that will lower the res
compress files to zip in pitstop and then change to cmyk under color/color space

Not sure what the image originally was, came from Corel and I do not have the working files. It is 2 colours though, black and Red 032 and shows up in separations as that. I was hoping when I made the global change it would make it for any colour that was Red 032 but that was not the case. So I do not want to just convert to CMYK, I want to convert the Red 032 to a specific CMYK value.

I usually use the Remap color function for images

That is how I did it, but the red in the bottom circle logo does not change:

The red in the circle is 100% a pantone and the same colour as the other red in the logo. In the test I did the global change to 100% cyan just to see if it would work.

Huh? Why would changing the color mode lower the res? I've never seen this happen, but maybe I missed it?

I don't think it lowers the resolution but if you use jpeg compression you can get the jpeg artifacts which makes it appear worse than before. The more compression the worse it gets.

That is a preflight profile with an action it. Does it need to be in the preflight profile for some reason?

Using the Global Change 'Remap Colors' does remap everything. You have to remember if you are doing any correction in the Inspector it only affects the selected items. Global Change or Actions changes everything from the Global Changes or Actions panel, ie...complete document, current page etc.

What do you mean by selected items? I was not clicking or highlighting anything when I did it.

I did just try again with these settings. I did not select anything in the PDF, just opened it, went to global changes, did what you see in the screen shot and hit "run"

I thought you tried via inspector the first time which is why I mentioned a selection.

Do it like this:

I think the method you used above does not work on an image because it just changes a user swatch in the PDF which is vector objects only.

Ok that way works, but I do not have an option to input a specific CMYK makeup. I was only using cyan as an easy way to see the desired change. I need to tweak the red to try and match closer what we have on press.

Doing it like this will change it to the CMYK makeup of the spot color. Then you could change it via CMYK ===> CMYK Global Change however that will not change the value in the image that originally had 032 spot color.
