Quote from: Joe on October 12, 2012, 07:53:02 PMMaybe I can make this even more confusing. I'll try my best.

When you output a PDF ID CS6 with PMS 185 C and use the standard job option for "High Quality Print" and Color Conversion is set to "No Conversion" (standard settings for High Quality Print) you get a PDF that has PMS 185 C with the alternate color space as LAB. If I open that PDF in Acrobat and use Pitstop 11 Update 1 to convert the PMS 185 C to CMYk I get a very ugly red C=0, M=87.67, Y=71.78, and K=12.33. Obviously the K=12.33 is the problem.

Now if I go back and output the PDF again from ID CS6 using the "Press Quality" settings which has Color Conversion set to "Convert to Destination (Preserve Numbers)" then I get a PDF that has PMS 185 C with the alternate color space as CMYK (Alternate Color Values are C=.9, M=100, Y=92.1, and K=0). If I open that PDF in Acrobat and use Pitstop 11 Update 1 to convert the PMS 185 C to CMYk I get a very nice bright red C=0.91, M=100, Y=92.14, and K=0.02. you can see that the conversion matches the Alternate CMYK color values. I don't know how Pitstop is getting the conversion numbers in the 1st example above. To be safe I would make sure and output the PDF using Color Conversion set to "Convert to Destination (Preserve Numbers)".

Now if you let Acrobat X convert the spot via "Convert Color", instead of using Pitstop 11 Update 1,  it converts it to the brighter red of the Pantone + 185 C (C=0.91, M=100, Y=92.14, and K=0.02) which looks great.

Either of the above PDF's, both LAB and CMYK, processed through Prinergy OK. Using my standard process template it uses the Prinergy Color Library which has the old Pantone numbers of M=91 and Y=76. If I change the process template to "Extract Recipe from the file" it gives me the brighter red of the PLUS library, ie...C=0.91, M=100, Y=92.14, and K=0.02

So the new Pantone + numbers for PANTONE 185 C is a brighter red than the old numbers but you have to be careful how and where that Pantone is converted to CMYK. Right now Pitstop 11 Update 1 will bite you in the ass doing with the color settings set as mine are. Which is "Off".

I specify Pitstop 11 Update 1 above because I don't have any other version...which may give different results.

So Joe are you saying the best way is to use the Convert to Destination (Preserve Numbers) when exporting PDF from InDesign CS6? And I have another question, how do they print on the digital press? We are practically almost printing everything on our Bizhub these days.

Yes, if you plan to convert with Pitstop or another software, RIP, etc...that may give undesirable results.

Digital Press = whole other can of worms.

Letting the RIP at the DP convert or convert in Acrobat or where? (Acrobat X does convert it correctly). If it is your DP RIP I'd definitely test it before running something LIVE.

It seems the Pitstop Color Management switched off is the culprit here when converting the LAB PMS to CMYK. If I tell Pitstop to use the Acrobat Color Settings it converts fine. You only get the ugly brown if you have the Pitstop Color Settings OFF. I leave them off most times as I like the gray scale conversions better with it OFF. But I sometimes turn it on if a conversion doesn't look right. I can usually use the Acrobat Color Management settings if the "OFF" settings don't look right.

So to refresh. Test, test, and test some more until you get your conversion where you need them.

Good info. Thanks.   ... from the Late Night Test Guy, correct?   :cheesy:   

So do I.

You do what?

Hi guys

I'm out of the office at the moment and unable to do much testing but let me give you some insight into how I think this should be handled.

I don't think you should try to convert the LAB to CMYK, if you do the results you will get will depend on the ICC profiles and color management settings of the application you choose to do the conversion (LAB to CMYK). I can almost guarantee they won't hit the numbers you expect to get if you compare to the CMYK breakdowns you get from CS5.0/CS5.5 (or any other pantone licensed application). Although the color might actually be more accurate if you have a color managed proofer.

If you have something that comes in that has a spot color with an LAB alternate color space you can set up the preflight profile to detect these so you catch them (ss attached), or you could create an action list to do the same.

The approach I would then recommend would not be to convert these to CMYK, but to change (Remap) the alternate color space from LAB to CMYK using the official pantone CMYK breakdowns that are available within the PitStop color database, that way you are remapping to the official Pantone colors (ss attached of the action for this, although you will have to load the required colors)

That would be the theory anyway, the reality might be a complete pain in the arse.

When you license the Pantone libraries you are given a list of alternate color spaces and the official breakdowns from Pantone, I would use these personally unless you have your own internal numbers.

If anyone's interested in perusing this then let me know and I will take a look at producing some stuff that might help.

I'm a little late to the game with CS6. Just started using within the last week so forgive me if this has already been discussed. One feature that seems to have disappeared is when relinking an image, the image is no longer highlighted when I point to the folder where the image resides. This was always very handy especially if I have a lot of images to relink. Saved me from having to search the folder for the particular image. I thought maybe this was a preference, but could not find anything.

Have to do some basic Place-images today. Shall test and see...

not sure if this helps you but you could "relink to folder" and let it do what it do.

Not weirdness, but not worth a thread in itself. In-house guy was checking a gatefold sizing with me. He was wanting to set it up properly before sending it up.   

He alerted me to the 'Page' Tool.  Then allow 'Spreads to Shuffle'; UNcheck Allow Pages to Shuffle) Then resize/butt pages to do an effective impo on it. In this case 150|149|149|148 mm.
I don't go into Indy a helluva lot lately, due to being solo op. mostly, and most stuff supplied PDF. But, question, was this new in CS6?

I think that was introduced in version 5, if I'm not mistaken.

That's OK.    :embarrassed:

I think it was in CS4 also. Maybe even CS3?
