Does anyone have Pantone plastic chips and...
« on: Tue, 13 August 2019, 16:37:01 »
Hey,

Does anyone have any Pantone plastic chips and a Color bridge (or Formula guide)?

I would like to see how they compare for the same colours. It can be just one or a few colours.

Thanks

Hmm. This should probably be in the keycaps section but oh well.

Any Pantone chip (plastic or fabric or paper) should be the same as the book color. That's what the system is meant to be. A way to reference a color by a number that anyone tell exactly what color/hue/shade you are referencing.

What would be interesting is taking a spectrometer to signatures, gmk or other's plastic color samples and making a cross reference sheet. (which might already exist) Using a spectrometer to get the color reading straight from the keycap producers plastic color samples. Pantone has a number of them but you could use other brands as well.

I saw Pantone has an app as well (iOS only as far as i saw) that can work similar to a spectrometer but results would vary greatly depending on lighting, etc. (picking a PMS color from an image captured through the phone's camera) This method would not be as accurate but would probably get you in the ballpark. If you were to go this method, i'd suggest using a camera card (color/grey card) & color correcting the photo before sampling for PMS. (to fix any lighting issues)

I also thought that they would be similar. However, I spoke with another designer and, without going into detail, there seemed to be noticeable differences between the two. I don't know how old their guide was.

My issue with the color guide (coated) is that I have a match in incandescent lighting and another in daylight. I suppose that Pantones are sampled in neutral light. From what I can see, the coated paper is more reactive to red light. I expect the plastic chips to behave more like keycaps.

Taking a spectrometer to keycaps and Pantone plastic chips would indeed be interesting and quite useful for rendering.

The books/chips will vary slightly depending on application. Have you ever looked at the differences between a coated guide and a solid to process guide (coated vs. CMYK printed). Or coated vs uncoated for that matter.... I'm sure a plastic chip is not the exact same as a coated (paper) chip, as the pigments for those materials will vary but they should be close. There has to be a margin of acceptability or we'd all go broke & insane.

Yes. Lighting plays a huge part in how the color (chips in-book or otherwise) are perceived. Probably part of the reason Pantone's light booth is still available.

The nice thing about a spectrometer is it takes the lighting variable out of the equation.

That's why I'm looking for pictures comparing plastic chips to coated paper.

The plastic chips are expensive and I want to narrow down the number of chips I need to order.

For example, if I know that the plastic chips are darker than coated paper in general, then I won't bother ordering colours that are already too dark in my coated guide.

yep. the plastic chips are their most expensive guide.

you might have better luck trying another forum more in the design/manufacturing realm to find someone with a set.
