iPad / iPhone colour

I have a logo that uses Pantone green (369c). When I look at a pdf of this logo on an iPad or iPhone the green appears almost neon. If I look at it on my laptop or Monitor the green looks fine. It is only the one colour that is shifting and it's really extreme. Has anyone else experienced a similar problem? It doesn't matter if I convert it to CMYK or leave it Pantone - the shift is still there.

RGB
- It's a proof for print. CMYK should be close enoughnosaj
- are you really arguing with good advice? obviously you're wrong or else you wouldn't be asking for helpmonospaced

does the iphone use a wide-gammut display? that might do it.

export sRGB (convert)
- I can do this - but was hoping to send the same PDF to the client to proof that I will send to the printer. It just seems odd that the Retina display can't handle a Pantone colour.
nosaj - That the Retina display can't handle a Pantone colour.

Don't color manage that image.

the client shouldn't be proofing Pantone color on a display, iPad or otherwise, in the first place, so your desire to use one PDF for both purposes is a bad idea from the start
your assumption that the iPad "can't handle Pantone" is simply naive. it's just an LCD.

Whatever they see on the ipad will not be what they see on the print, so to proof there is useless.... and did you say you are using CMYK for the proof? Ipad likely doesnt technically display CMYK - since it's not a 4-color process display... its an rgb display, so if you're sending a cmyk document to view on a screen, its being converted to RGB. You have little control over that conversion process unless you specifically use RGB as the color format in the first place.

The client is proofing an ad, not colour accuracy. The issue is that the colour shift in the pantone colour is so extreme it is distracting.
I haven't noticed a shift like this on any other display and have tried several.
- so, we come full circle: export a freakin' RGB PDF!monospaced
- there should be no color shift if you do it right as rgbmantrakid

CMYK on a screen is:
1) NOT the way it will look in print
2) NOT the way it should look on a screendont use cmyk for his screen. use RGB.
RGB is meant for screen. CMYK is meant for 4 color process printing.
If you were sending his job to get printed on a 4 color process printer, you would send the printer the cmyk file, as it has separations for the color that the printer understands and works with. If you're sending a digital file to a client to look at with their eyes on their ipad/phone/computer/etc you use RGB because that is what their device is systematically programmed to understand & output.

I get how it works.
Yes, I could export one RGB PDF for the client and a CMYK version for the printer, but am hoping to not have to manage 2 versions of every ad that goes for review.
I have sent CMYK pdfs to clients to proof content before going to print hundreds of times and have never noticed a colour shift this extreme on any other monitors or with any other colour.
- Why 2 versions, surely the printer only gets the final artwork, or are they checking content as well?MrT
- We often do quick turn around ad variants that get sent from an account manager to the client for approval before going to the printer.nosaj
- off to the printer. If the Account Manager, client and printer can all work with one file it makes the workflow easier.nosaj
- I get it, but this is how it works; this is how it's done in the industry.monospaced

nosaj is making sense - he's just pointing out the weird display issue. not asking for a lecture in the difference between rgb and cmyk.
- but he still has to make two PDFs, it's just how it ismonospaced

If you are using Pantone then color, regardless where and how you print, should be the same; Pantonte is just a formula to standarize thousands the output of colors.
Can't you ask for proofs from the printer and see whats up? If the color isnt coming out the way it should, then I have a feeling is the printing folks who need to calibrate their machines. Or better yet, ask the printer to give you a color chart of all the Pantones, see if the one you chose is the same as the one on the chart. Otherwise, pick another that's similar to yours.

Just cuz previous clients didnt notice a color shift doesnt mean it wasnt there, the fact remains the color looks wrong because its a cmyk document meant for print but displaying on the screen. some colors will look a little wrong, some colors will look really wrong. if you want it to look right on the screen, format it for the screen. for fucks fucking fucks sake.

i dont know why i even care..

As long as your client see's the correct colour on their iPad just send the RGB PDF on to the printer and let them handle it ehh?
I jest, just set up a script to run out both RGB & CMYK PDF's it won't take that long shirley?

methinks this dude ain't setting up scripts for shit.

I'm surprised my question about how iPad displays interpret CMYK documents upset you so much.
To be clear, Pantone, CMYK, RGB - I get it.
What I don't get is why it's so difficult to understand that there may be a situation where having 1 print ready CMYK file is the easiest work flow.
In my case, we create a ton of variations of the same advertisement to run in different publications. These ads go to an account manager who has the client quickly review the copy (it is all that changes) before sending them to the printer. This may happen a few times a week. Sure, having an RGB version for onscreen review and a print ready version would give the client a more accurate sense for how the colour in the ad will appear in print, but they are only interested in proofing the copy. That said, if our account manager only has to deal with one file it can make their job simpler and more efficient. Sometimes time is so tight that the Account Manager has to forward the client review email with the attached .pdf to the printer from their phone in order to make press in time. It needs to be fast and easy.
I just recently noticed how different one specific CMYK colour is displayed on the iPad compared to the half dozen or so other screens I have looked on. I understand that CMYK isn't meant for the screen and that the device has to interpret this which can lead to mixed results. This has no impact in on this specific project. I was curious as to how iPad handles the interpretation of CMYK compared to the variety of PC and Mac setups that seem to handle it relatively consistently.
Is this really that poor of a question to ask here?
- that's really a question for Apple, I'd say, not for "here."monospaced
- it sounds like color profiles and conversions that might be out of your controlmonospaced
- It really comes down to what we said from the start: don't proof on an iPad!monospaced
- don't blame the iPad, blame the Account Managers for using them to proof CMYK filesmonospaced
- I'm done.monospaced
- You don't think asking a question about how colour is displayed on an iPad is relevant in a design forum?nosaj
