Using Illustrator on Mac OS 10.7.4
We've been using Illustrator for years and have come across a problem we never encountered before.
PMS spot colors appear washed out on the screen and appear washed out when viewing them in a pdf.
Customers are complaining about their proofs as well.
Have you recently upgraded to CS6? I have noticed with Pantone updating to their PMS+, some of the screen-views and PDF views for the spots are no longer consistent with prior versions. If printed with the spot-ink, the final production should be the same, but if your are going the digital printing route (where everything is done as CMYK or RGB) then you may have to have your press operators give some more detail to make sure the colors are matching properly.
Just to get more info: what color mode are your documents in? What settings are you using to write out your PDF's?
Although I haven't run into the problem with CMYK jobs yet (I'm not looking forward to that) we have run into big problems with digital color output. Colors which printed consistently days before are now completely different. This has really turned into a very time consuming nightmare.
It seems that the spot colors which used to have a CMYK profile are now LAB and I can't change it easily. Besides that, it seems to change intermittently from day to day. I have no choice but to delete all the preference repeatedly.
Is there no other way to handle this? I can see others are having similar problems.
I am trying to get my hands around this new LAB representation and how they affect screen view. It appears as though there has been a major setback in color communications. It also demands a full explanation and correct workarounds from Pantone.
I can see that the actual problem is with the new Pantone Plus Series libraries for CS6. I can't understand why they would effect digital color output, but they do. The whole thing is terrible and I've ditched the new color libraries for now and replaced them with the previous libraries which seems to have taken care of the problem for now.
Does anyone have any other solutions or explanations of why the new Pantone Plus Series is such a mess?
Pantone Plus Series uses Lab color definition in order to make better simulation (on screen) and better CMYK conversions based on the Color Settings preferences in Adobe graphic applications.
When I say "better CMYK conversion", I mean CMYK separation based on the intended printing condition defined by the CMYK ICC working color space set in your preferences.
It is working.. I use it every day.
Worst issue:, if you do tests with Pantone Plus Color Bridge default CMYK values, you will be amazed to see the difference!
Just try Pantone 424 Coated (a gray), and check the CMYK values from Pantone Color Bridge Coated.... completely different! WHY? Because those CMYK values has been define by Pantone, using an "international" ISO printing condition!!??
I’ve tried to find out the ICC profile that could match those CMYK values but did not found it yet.
So, it is better to make your own CMYK match, using those new Pantone Plus color libraries (in Lab) than using a "generic" CMYK build that would create a nightmare on press if even it is not made for your printing condition.
Hop this help!
Thanks Louis for your help.
We experienced an unexpected color shift for digital color output. Where we had consistency for our customers who are very concerned about color, now we are having issues due to the new color profiles. We unfortunately had to remove all of the Plus Series profiles and replace them with the old ones. Our customers were also complaining that the colors appear differently on their screens for the proofing process. (They don't care what explanation I give them as far as Adobe attempting to improve things.)
So far no one from Adobe has been able to tell me how to use the Plus Series profiles without changing color on output. Very frustrating.
In order to get the best Pantone "solid" preview in Adobe Illustrator or InDesign, you have to select "Overprint Preview" from the view menu. This, tells Illustrator and InDesign to display Pantone colors with their Lab reference. If "Overprint preview" in not enabled, this tells Illustrator and InDesign to use the CMYK conversion of the Pantone colors.
In Resumé, if no overprint preview selected, Illustrator will use the Lab value, pass it to the CMYK working space (profile selected in the color settings) and will use the default rendering intent of the color settings preferences. So what you are seeing on screen is not the real Pantone but the CMYK conversion of it.
So, when you want to see the best simulation of Pantone colors, use OVERPRINT PREVIEW. Be carfull that not all Pantone color can be simulated accurately on screen.
Let me know if this help!
I'm still using CS5, but received a PDF from a client. I am able to open in Illustrator and edit it. I am trying to change from process to spot and when I select overprint preview, eveything is gray and digital printing is gray. I've tried opening a new document and that has the same problem. I am not using Pantone Plus or CS6 Pantone colors. This file may well have been created in CS6, but that shouldn't affect my color palets.
I'm at a real loss as what to do. I need to proof out this job and hopefully not have to try to explain this to my boss. I need a work around or to figure this out.
