full quality screen shoot of my view

Hello,

i am working with projects which use pantone colors... and not one adobe software can give me the same colors after merging pantone colors as they were before shown on my display...

why can not photoshop or ilustrator or indesign just take each pixcel color and export it to rgb... (my display is showing current pantone colors in rgb so i should get the same resolut after merging or exporting view layer)
i understand if you are merging pantone colors like you transfare color to rgb and than merge it than it can not work... so why adobe just does not take each pixcell color curently shown on display and instead of converting to rgb and than merging theese rgb layers... (this seems like what merging chanels do)

 

So my idea would be to add button which will export current view in its resolution... it would also help people if they would like to export measurement lines or picture boarders... just something like screen shoot but in the same resolution as project is...
You could make script for it which will zoom the view to have one pixcell the same size as current screen and take multiple screenshots and combining them to one high resolution picture

Hello.
almost 2 months ago i found a solution for this issue. But i had no time to share it...

So from what i understood this is what is doing photoshop during merging: photoshop convert each pantone layer into RGB and than photoshop starting to merge it base on density of that pantone color.
This works until the pantone colors are in color range of rgb. But when it is out of gamut (yelow triangle with exclemention mark) than it start failing. Becouse when the color is out of gamut that could mean places with more density or placess with more alfa chanel could have more saturation at the end than normal places. This is where photoshop is failing... photoshop just can not flat out all pantone color to only one rgb layer and than merge it... 

That is my theory what is happening inside photoshop. Becouse screenshot which is taking picture pixcel by pixcel shows way better resoluts.

 

 So i start thinking how could i take exactly the same quality screenshot of visual.

At the end Ilustrator works (merging transparency works like screenshot if you uncheck preserve pantone colors)... but it still has few issues but they are way less visible than false colors in photoshop. (in ilustrator... you should merge as less staf as possible becouse at the end around sharp edges it could make some artefacts... so in the best case merge only pantone layers and other texts or png add on top of it... for my case we are geting printing artworks in ilustrator... so i just take background pantone layers which are link from photoshop. So i do not need to do almost anything)

so 1. step check only layers which has some pantone inside... (not gold or silver ones theese pantone colors need to be faked by hand or replace in 3D by gold material)

 

2. step set document color mode as RGB if you wont RGB.. if you wint final image in CMYK than set cmyk (if you not sure always chose RGB - it has better color range)

 

3. step go to Object/Flatten Transparency...

 

4. step in new window uncheck all checkmarks... and both ppi text box set to your ppi which you will be exporting (i amd exporting in 1200)... and slider set to 100

 

5. step press OK (your layer will be merged... if you checked more layers they mabie jumped higher in your layers... so make sure you are not hiding anything below...)

 

6. step export as PNG set ppi you set in step abowe and make sure you checked Art Optimalized (Supersampling) if you would not do Supersampling than there will be Hairpin micro-Strip lines from the flattening.

 

And now you have wisibli way better merged pantone colors than from photoshop.

Here is the resolut

1. is photoshop merging pantone

2. is original screenshot from photoshop

3. is flattening with pantones in ilustrator

you could see still tyni diference... but it could be just becouse of preview settings of ilustrator... can not tell which one ( pre merging or after flattening in ilustrator (2. or 3. picture) looks more simular to real print product... hard to tell diferent lightning in real life diferent color, reflections... ... ...) but the resoluts are absolutly fine now...

 

So that is the solution for us... we allready using it for some time - no problems yet... and waaay better resoluts... for us it is also faster than opening each photoshop layer merging pantones there... and i am not tallking about how long workers here tryed to repair the colors after merging it to get something better than what you see photoshop does...


Hope this will help to someone.
Have nice day.
With best wishes Dominik Jiruše

Hello,

combining 158C, and 317C in prophotoRGB does noto make any visible diference

OK, I assumed that orange could be held in ARGB, but apparently not.

 

In order to troubleshoot this, it is absolutely essential to remove out of gamut from the equation. If this is not a bug, out of gamut is the only explanation - except if it was a noisy image. Is it? Then you need to compare at 100% (insert long and separate explanation here). I didn't get the impression that there were any noise effects here.

 

So we have two Pantones that are definitely in gamut: 158C, and 317C. How do those two behave?

 

But all in all, from what I get from the above posts, it does sound like a bug.

    I've just had another look at this today as it puzzled me.

     

    I opened a document in Lab and filled with each of the named Pantone colours and then used Photoshop's proof colours and gamut warning (yes I'm aware of its shortcomings but I just wanted an indication as to what might be happening)

    Pantone Orange 021 C shows as out of gamut in both sRGB and Adobe RGB. It shows as in gamut in ProPhoto

    Pantone 158C shows as in gamut in sRGB

    Pantone 317C shows as in gamut in sRGB

    Pantone 7474C shows as out of gamut in sRGB but in gamut in Adobe RGB

     

    So the step change does indeed look like it may be due to out of gamut colours and how those need to be contained in the document profile gamut after merging.

     

    Building the two starting documents in Prophoto showed smaller changes on merging. Surprisingly (to me) creating the documents in Lab and merging there resulted in a similar visual shift to that seen merging directly in sRGB, but without seeing the inner workings of the spot channel merge I can't explain it.

     

    So the closest on screen results I got were building the docs in 16 bit ProPhoto and merging there, but that still resulted in colours that were out of gamut for sRGB so regardless some correction is still needed if a document contained in the sRGB colour space is the intended outcome.

      If this happens in an Adobe RGB file, and the color is definitely not out of gamut - then it looks to me like a bona fide bug. But again, my experience with spot is very much lacking.

      Hello,
      AdobeRGB does not make visible diference from my perspective... both of theese screenshots are from adobeRGB before and after spot colors merge (left one before - right one after)
      here are the AdobeRGB project files if you would like to see with your own eyes (as you can see screenshot can capture the diference so i think my idea of photoshop full quality something like screencapture export would be working better than merging chanels like this) and it could also help people which would like to export measurements or image borders...

      Pantone 7474C, as defined by Lab 43 -35 -18, is outside sRGB gamut. It can be reproduced in Adobe RGB.

       

      This screenshot has Adobe RGB embedded and shows the difference, if seen on a wide gamut monitor (the inline image has the profile stripped, so click to show it correctly):

       

      Now, I don't have any experience with spot channels and don't really know how out-of-gamut colors are treated.

       

      But if you try this again in an Adobe RGB document you can tell us if you see the same there.

      Hello,
      thanks for your help

      1. oh yes i foregot to convert coconut (greenish) project to rgb... but it is just worse when i would use cmyk becouse of cmyk low color range...
        Normaly we get theese files in cmyk... so i does every time convert them into rgb...
