I’m sure this has been discussed plenty, but I need help creating PDF’s with a few important pre-defined RGB colors, but with 100% black text.
I am getting more confused by the hour, right now I can’t even create a PDF with RGB color and mixed black.
We are trying to create an RGB workflow because our new colors are very RGB-vivid and we need to keep the documents vivid for web use, and then let the printer’s deal with conversion for print. Without ruining black text.
Why are you making my head explode so early in the morning.
Sorry to be ornery but this is happening far too often lately. I’ve had a handful of jobs in the past few months where the final prints did not come out as the designers intended and RGB workflows were involved in two of them. They paid for new prints on rush overtime.
“let the printers deal with the conversions for print”?
Your vivid RGB colors will convert to garbage and I’m pretty sure you won’t be pleased with the result.
If you are going to rely on the printer for that conversion, tell em the black should be straight up 0-0-0-100 black. If that’s what you want. Apply it as a spot color so they can grab it by mucking with your PDF, as the [Black] in the color palette is not editable. It’ll be a grayish black rather than a rich black. Depending on the source software there are options for printing all black as rich black but I’m not sure there is a way to tell it to be just K black in an RGB PDF for handoff…
Maybe Smurf2 has an answer for you, I don’t deal with conventional printing often enough to advise and my industry doesn’t take PDF handoffs on purpose. We’ll take em, but you get what you get if you don’t want to pay for heroics…
Mechanically, assuming your source is an Adobe app, what you want is easy: Export to Adobe (Print) PDF and choose the PDF/X-4:2008 preset. That will preserve both your RGB colors and your black of 100%K.
That sounds like “corporate” colors; ill-chosen ones, perhaps.
Best make sure your printer is on the same page with you there. If your corporate colors are outside of the CMYK gamut, it would be better to specify them as spot inks. RGB-to-CMYK conversion at output is doable of course, but if those vivid corporate colors are important to the brand, there will be disappointment, and likely extra time and $ getting satisfactory results.
What software applications are you using? Are you referring to RGB in photos that you imported into a layout application, or are you referring to RGB colors created in the layout application? Will you be sending the PDFs to digital or offset printers?
There are way too many variables in what you’ve described to give you a good answer without knowing more about what you’re doing and how you’re currently trying to do it.
Personally, I’d avoid doing what you’re wanting to do, but hey, that’s just me.
The vividity of the RGB colours will be monitor dependent.
I have my monitor set to a cool - I don’t have vivid colours on my screen due to tendency to get migraines, so my monitor colours are turned right down.
I can manage as I have a knowledge of colour that allows me to see beyond the monitor so to speak.
I never trust the monitors colour anyway.
Anyway, just to say, RGB-vivid images, will be different for everyone.

Sounds like they have some new corporate colors that are gonna be vividly out of CMYK gamut.
Based on your clarifications, here’s what I might do (without giving it a ton of thought).
Assuming we’re discussing 2–4 corporate colors, I wouldn’t resort to a 100% RGB workflow for all the reasons (and more) that you’re running into. No matter what you do (short of a Herculean effort) everything in all your documents sent to printer will be converted from RGB to CMYK. This will cause, to a lesser extent, the same problem you see with the text — RGB colors converted to some approximation of those colors in CMYK.
Instead, I’d probably build the documents in CMYK and use spot colors for the out-of-gamut corporate colors. Even though you might not have the budget to print spot colors, as a last step in making the CMYK PDF for the printer, you could convert the spot colors to CMYK. This conversion would only affect the spot colors and leave the other colors, such as the black text, as they were in CMYK.
I’ve run into this problem for years in publications that accept advertising — some advertisers invariable send ads with spot colors, so every single time, it’s necessary to convert them to CMYK before sending them to a printer. Fortunately, it’s not a huge problem to identify those colors with InDesign’s ink manager and make the last-minute conversions in the packaged file while leaving the original InDesign file unchanged for use as, for example, a website PDF. Rather than explain it, here’s a link.
If you are sending work out to digital printers, they might be capable of a larger color gamut than the standard CMYK. You might want to talk it over with the digital printing company for suggestions in those instances. Their printing devices might be able to get closer to your corporate colors than standard CMYK. Those companies might ask you to convert the spot colors to LAB values in the ink manager rather than process. Or they might ask you just to let them handle it.
For what it’s worth, it was stupid of this company to select corporate colors way outside the CMYK gamut since it will complicate every printing job they ever do and result in their corporate colors not being unless they pay for spot-color inks. Of course, that’s not your fault.
You do get a CMYK breakdown - however, this is only due to the output intent (which you can talk to your printers about and you can get a better view on screen by choosing an output intent your printer might use).
Yes - i’d endorse an InDesign workflow in this case.
The ink manager is quite clever.
I had to setup a complex Pantone 021 vs CMYK scenario and I had cleverly built one file to accommodate whether it was going to printed spot or CMYK - that I could switch colours over in the Ink Manager by aliasing the colours.
I’m referring to RGB colors / swatches for vector elements in InDesign. But more specifically, I am referring to placed vector files from illustrator, in .eps or .ai. I am having trouble getting the 100% K + RGB swatch colors in Illustrator all the way through to the PDF created in InDesign – while retaining the black text and RGB colors in the InDesign document.
This should be easy IMO, just keep everything as is, no conversion. But I am missing something somewhere along the way. Am I perhaps missing some settings in the Illustrator file? Can Illustrator even handle RGB + CMYK in the same document?
PDF’s will be sent to all kinds of printers (big corporation), and also printed inhouse. Thus, a more automated workflow would be preferable. In certain instances, spot colors are used (merchandise and such), but that is off-topic.
As far as I know, it’s not doable. In Illustrator, you pick between two color modes: RGB or CMYK. Even if you color something 100% K in an RGB Illustrator document, Illustrator treats it as rich black RGB.
However, you can add spot color swatches (different from the process color swatches) that can move with the document to InDesign, which brings it back to the suggestion I made earlier.
There might be an awkward workaround that could somehow be adapted into a standard workflow, but I can’t think what it might be. My gut hunch is that, in the end, you’ll need to create separate RGB and CMYK documents — possibly doing everything in CMYK, then changing the relevant CMYK value to RGB when using those files for digital/web use.
