Can You Match Pantone Viva Magenta?
I can answer that question. First you need to find the color definition before you can determine whether you can match it. So, where can you find it? I found it by logging into the connect.pantone.com website and searched by name. Turns out there are 2 Viva Magentas – 18-1750 TCX (in the PANTONE® FHI Cotton TCX – library) and 18-1750 TPG (in the PANTONE@ FHI Paper TPG – library). And guess what… these are two different colors (because one is dye on cotton fabric and the other is lacquer coating on paper). You can see them both here…
If you click on the swatch and choose Color Data, you get to see the most pertinent information – which is the specific L*a*b* values. As you can see in the screenshot below 18-1750 TCX LAB is 43.60, 61.25, 20.98 and 18-1750 TPG LAB is 46.05, 58.95, 17.38.
So, now you know the actual color, or colors, not just the name of the color – named colors are dangerous, always pay most attention to the actual target values. Now what do you do with these values?
I used a cloud-based software from ChromaChecker to create the digital swatches, simply by typing in the Lab values…
Once I entered both colors I compared them to one another to see their difference…
Now I want to see if any of my printers can match these colors and what the best possible CMYK values are that I should use on those printers to do so – heads up, the CMYK values will always be different for different printers/medias because they’re device-dependent. I can do this a couple of different ways. I can use the Virtual Spot Print functionality in ChromaChecker, which works by uploading the ICC media profile(s) (usually found in the RIP software) and then converting the spot color into this color space.
In the example above I’m using an ICC profile from an HP-800 on 3M IJ180 adhesive vinyl at 600 dpi and 8-pass mode. You see the original colors on the left and the predicted Lab and CMYK values on the right, as well as the Delta E (2000) on the far right. Zero Delta E would be identical (no difference/perfect), the higher the delta E the further out of gamut that color is. Seeing that both colors have EXTREMELY low dE (.11 and .02) I know for certain I can match these colors on this printing machine.
What I just showed you is awesome and the Delta E number is really all you need. But many right-brainers, like me, would like to visualize this. To do this, I simply export the colors to CxF format and drop them into a 3d gamut viewer like Chromix ColorThink – and then load the same ICC profile to compare to…
Now, keep in mind that what I just showed you was a prediction. It says the color is certainly “in-gamut” and that we should be able to reproduce it within a very small deltaE difference. But to know for certain, you should actually print the color, measure the results and compare with the target color – this is how we verify the color is correct, EVERY TIME we print a job with this color. To do this, I used ChromaChecker Capture software to create a Control Strip (artwork that I can print and measure). I printed this PDF through my RIP, then measured both swatches.
Here are the actual measured results. Not quite as tight/low on the DeltaE predictions but very good match!
So, the answer to the question is… Hell yeah I can match Viva Magenta(s)! And you can use this method to find out if you can match any given spot color. Give it a shot and let me know what you think.
