WIN JS CS2 Covert Spot Colours To Process

Hi all,
Any idea why this doesn't work?
app.activeDocument.inks.everyItem().convertToProcess = true;
I need to convert all spot inks in my swatches to process
Thanks heaps
Regards
Norbert

Norbert,
>Any idea why this doesn't work?
You're looking in the wrong place. Change colours, so to speak, not inks: myColor.model = ColorModel.process
You can't use everyItem() because some colours can't be changed, so you need to iterate through the colours and try to change each instance:
c = app.activeDocument.colors;
for (i = 0; i < c.length; i++)
try {c[i].model = ColorModel.process}
catch (_){}

Spot colour overprint

Hi, all
I've got a premade PDF file with a spot colour overprint on an image with a white line art logo on top. I want to convert this spot colour to process colour and preserve the overprint in the mean while. I used PDF X, convert colour, it turns out that the overprint is gone and the white logo was shaded to that spot colour, the worse is I even lost the background image. I also tried flatten image in vain.
Is there any solution to convert spot colour to process colour but preserveing the overprint as well?

Hi FanieJansen,
how do you know that the Overprint Preview is wrong?
The only real way to know what the result is of mixing process inks into a solid spot and how the resulting tints will look like, is to print with the actual ink.
If you look how a similar spot color like Pantone 4625C would behave you will see the same greyish preview.

How can CS2 not recognize spot colours in an imported .eps file?

Hello
I am using InDesign 4.05 on OSX10.4.11. I have been using InDesign since 1.52 and have always regarded the program as exceptionally bug-free apart from lately as I use CS2 more and more. I am reluctant to upgrade to CS3 just yet.
I am pretty sure I have never seen this behaviour before. If I import an eps of a logo which only consists of two spot colours, the colours are added to the swatches but show as CMYK. Of course if I preflight it then wrongly shows that the doc is CMYK only. If I then create a PDF and then check the PDF in seps view in Acrobat, the colours are showing as CMYK???? I have checked and rechecked the logo with the spot colours in it in Illustrator CS. They are 100% definitely showing as spot. If someone else told me this I would not have believed them - please tell me I am not going mad. What could cause this?
ps. I have another piece of extremely odd behaviour too, which I will do as a separate post.

propage,
I have no trouble at all placing that EPS in CS2. Both spot colours show up.
I distilled it and checked in Acrobat, too.
The only problem is that the lower right yellow bit is *not* a spot colour in Ai.
The detail that the colour names are added to the swatches when you import the EPS indicates that the spots are in there.
That leaves only the conclusion that something is wrong woth your Id document e.g. there are process-swatches of the same name before you place the eps.
>I take it I should abandon eps and move to ai?
Buko would certainly and definitely say so. That's why I quoted him ;)
Most of the rest of us think there are special workflows where working with eps still makes sense but the are rather few and when only Ai and Id are involved Ai is almost always the better choice.

PDFing Spot Colour Transparencies from Indesign CS2

Hello!,
I think this is a common question, but I can't find a definitive answer. I am trying to PDF a file which has an image and then a spot colour transparency over part of it. When I PDF the file at Press Quality the spot colour transparency is white. When I PDF the file at a lower resolution (Standard size PDF) the transparency is fine.
Is there some way I can resolve this? I need to prepare a Press Quality File. I seem to recall reading or hearing somewhere that Indesign does not deal with spot colour transparency very well. I am currently working in CS2, and am wondering if the issue has been resolved in newer versions of Indesign.
Many thanks for your help, all,
Pepi

> that Indesign does not deal with spot colour transparency very well
Nonsense.
Just turn on Overprint Preview in Acrobat.

PDF and Spot Colours

I have a problem with Illustrator CC. I have a file with spot colours in it. I have converted these spot colours to CMYK, but I still cannot save the file as a PDF-X. An error message continues to pop up saying I have spot colours somewhere, but I have no idea where. How do I save the file as a PDF-X?

At first yes, but now no. I had to modify the colours to match some samples I got. And yes the error message reads: Cannot output this document because it contains more than 27 spot colours and uses transparency. Delete some spot colours or convert them to process colours and try again.
The thing is I did that. I got rid of the colours and transparencies I wasn't using for one of the files but I still get the same message.
I'm saving it to a PDF/X-3:2002 but no matter what preset I chose it just doesn't want to work.

RGB image coloured to spot colour

We have supplied images (jpeg, tiff, wmf) that are RGB Black & White. I want to be able to place the image in a box and set the colour to a spot colour ie PMS 280.
I can colour them up using Transparency>Lighten having set the background colour of the box. This only works for process colours, not for PMS colours. As soon as you change to a PMS colour the image "disappears". Am I doing something wrong? Is it possible??
I work with Overprint Preview ON to get a view of how it will output.
Due to how the customer supplies the files to us and automation involved it has to be done via Indesign.

Not going to happen.
You'll either need to make clear to users of the template that they need to supply the correct form of art or do the conversion yourself. I expect it could be scripted to find these images open them in photoshop, run an action, and return them to ID as grayscale. It probably could be set to run on file open.

Making a PDF with an image that has both spot colour channel and alpha channel

Hi I have a logo that was supplied to us as a PSD it has a transparent background, it also has a pantone colour channel. I have made a alpha channel from the transparent background as well.
The graphic looks fine in InDesign (alpha channel selected in the import options), ie the background is transparent.
But when we try to make a Hi Res PDF the result is that the graphic is on a solid white background.
If I go back to the PSD and merge the spot channel with so that it is just CMYK and try again the PDF is fine, but we obviously loose the spot colour.
How do you make a PDF with a transparent PSD that has a spot colour?

You know that annoying response from support staff? "We cannot replicate your issue". Well....
I created a PSD in CS5, with a bunch of process stuff, then loaded a spot color channel and painted in some pawprints using Pantone 172C:
Saved this as a PSD file, default settings (maximize compatibility on, but it doesn't make any difference in this situation).
Created a new InDesign document in CS5, added a gradient and some text, then placed the PSD. ID understands the PSD has an inbuilt background so there's no need to bother with a dedicated alpha mask:
Exported from ID using the High Quality Print option (PDF/1.4, which keeps the live transparency):
Re-exported to PDF/X-1a (based on PDF/1.3 which flattens transparency) - looks exactly the same. In all cases the spot channel is intact and the see-through regions of the PSD are maintained.

Colour management of spot colour channels

Hello
I have some single layer images using cmyk (black only) + Pantone Process Blue U that will eventually be printed on a sheetfed offset press. A ballpark estimate would suffice for this low budget book, so I thought I'd give soft proofing a try. I'm therefore interested in understanding Photoshop's implementation of colour management for spot colour channels so as to have a less vague idea of the approximations this workflow involves.
Moreover, I'm stuck on exporting to pdf to let the client evaluate my conversions of the original rgb scans. Photoshop seems to layer an Euroscale Uncoated v2 overprinting image on top of a spot coloured image whose alternate colour space is "Calibrated RGB". What baffles me is that the pdfs display consistently in Acrobat 8 and 9 but rather differently from the Photoshop document.
Here come my questions:
1) Am I right in saying that these programs still don't support colour profiles involving spots? If so, are Adobe people willing to comment on the relevant intricacies?
2) Which colour profiles and colour conversions do Photoshop and Acrobat use to display such documents?
3) Which software tools will allow me to convert the Photoshop documents to an output profile for hard proofing?
4) Short of alternatives, when only K is needed and as long as each spot colour bears a decent resemblance to a cmy primary, how well will the profiling software deal with a cmyk target printed substituting the inks on press?
Thank you very much for your help.
Giordano

As far as I know …
1) Photoshop uses the Spot setting from your Color Settings (Edit – Color Settings) to display spot channels (and one can use gray-profiles or the K-channel of CMYK-profiles for that); the Solidity one can set manually, but one should bear in mind that even a 100% solid spot channel does not knock out the process channels.
As for the actual physical properties of the color and its mixing with the other colors I’m afraid Photoshop produces a pretty rough simulation – profiles for more than four colors are considerably more complicated and would, if I’m not mistaken, preclude much of Photoshop’s functionality.
2) If you pass unprofiled Files between programs they will be displayed using the programs’ respective Color Settings.
And your screen profile will be employed in the process naturally … but you might want to read up on color management if you want to know more about all that.
As to why the display differs between Acrobat and Photoshop it would appear that Acrobat use the RGB-setting for displaying spots and not an extra setting like Photoshop.
3) Photoshop is capable of separating files – but I may not understand what you’re driving at.
4) Epson-proofers using the latest generation of inks for example have a fairly wide gamut and should be able to simulate a lot of Pantone colors, so you might want to contact your provider to make sure if such a workaround is necessary at all.

Acrobat CC doesn't show or print spot colours in a Photoshop PDF

When I open a Photoshop PDF, with a spot colour channel, in Acrobat CC 11.0.04, the spot colour doesn't show. But it shows when I click Output Preview (in Print Production). The colour doesn't print either. It also disappears when I convert it into CMYK (by checking the "Convert All Spots to Process" box in Ink Manager). I'm running Acrobat on OSX Mavericks.
Has anyone had similar problems?
Any help is appreciated.

Thank you for your reply.
Indeed, I tried saving a PDF that had the "default appearance", it shows exactly the same. So it looks like it "can't" show the image.
However, of course, I do want the image to be shown. How can I achieve this? How can I tell Adobe Reader (and other PDF viewers) I really really realllyyyyy want to see that image there? I believe I'm not doing anything really exotic, right? There must have been tons of other people that wanted to do the same thing, I guess?

Having problems with Spot Colour gradients

Hello All,
I have little experience in dealing with spot colours. I'm trying to blend two spot colours for a print job. Unfortunately the spot colour gradient (left image) does not blend like the process colour gradient (right image). Instead they fade to a lighter colour in the center where they meet. I'm sure someone out there can help as I think this is more of a technical issue that I am simply unfamiliar with. Thank you in advance to all comments!
Hugues

Hello, i run into this all the time.
What you can do is actually make one spot color overprint (or darken, or multiply) on top of another one.
that will work,
What I see you have is one spot color at one end and another spot color at the other, where they meet you get the "grey".
The 4/c gradient is a blend of the C<M<Y<K, inks.
I usually rant over the fact that Illustrator does not have an Ink Manager, to make a swatch of 2 (or more ) spotcolors.
As far as color gamut goes, 4/c color printing is so passe, right.
Till Adobe recognizes that printers print with more than the 4/c color space, hexacolor, opaltone, optimized 7, and 8 we just have to improvise.

2 spot colour pictures for print

I have CS2 on a pc and can only seem to make pictures in RGB or CMYK (4 colour) this means the printers have to print in 4 colour. I want to print in 2 spot colour. How do I produce the appropriate artwork?
Many thanks

You either want a duotone image, or you want a grayscale or CMYK image with spot channels.

Spot colour blues

Hi Guys (and Gal's)
I have a little problem which is slowly turning into a major irritation. What happens is that I create spot colours, say one for Silver and one for Metallic board. The relevant objects and elements are "coloured" as required, the file saved and all the colours are okay / correct / in spot.
Yet when I open the files later, the spots magically convert to process. Not even global process colours, just the plain old colour makeup in process that
I chose for the colour. (Which was definitely a spot when I saved it). For some reason this issue happens mostly to light grey's or colours intended to
be "metallic".
And what blows my mind even more is that the one file where the metallic board changes from spot to process is a file that was made from another file
of a variant that uses the same design only with a different colour in one of the logos. For instance, FILE A would be the file I used, metallic board, blue spot,
silver text etc. saves fine, opens fine... the spots stay spot colours. Then I copy the file to another "variant" folder, change the blue spot to green, save the
file, the spots are spot colours. But once I open the file again the metallic has turned into 0c 0m 0y 25k. Yet the "blue" one is still as I saved it.
Have any of you guys come across something like this before?
Regards
JC

HELLO
i don't understand very well,maybe is better that you try again,try to see if working your pictures in filter and gone to light effect ,open this to material
effect,try to move the slider on the left and move to plastic direction...maybe is only a little light adjustment issue.(ps4 for this is the same of ps5).

How to delete a spot colour swatch set up incorrectly

Hi i'm running indesign CC2014 and having problems deleting a spot colour swatch 877 initial set up incorrectly as a lab spot colour, rather than choosing from the colour books
I've since converted it to a processed lab colour and still it won't delete. I also can't i find the colour and where it is used in my document.
I've tried to add metallic coated 877c (correctly this time) swatch again but it won't allow two swatches with the same name.
Can anyone help as i really need to correct this for the printers.

Is there anyway to find this out as i'm dealing with a 60 page brochure and not easy to manually find.
You can use the preflight panel to find all instances of a spot color.
In the lower left corner of the doc window you can define a preflight profile and apply it to the document:
Here I've made a profile named No Spots with Spot color checked under Color Spaces not Allowed
With Preflight on the profile will list any placed objects using a spot. in this case a PS monotone named Untitled-1

[CS4-5.5][JS] Problem convert spot colors to process

Hi,
I'm trying to convert all spot color swatches to process, but for some strange reason, some weird behavior occures.
First I tried this piece of code...
app.activeDocument.colors.everyItem().properties = {space:ColorSpace.CMYK, model:ColorModel.PROCESS};
After running the script, the color icon changes, indicating the colorspace/model is changed. But when checking the color in detail, it's still a spot color.
Just as a test, I tried this piece of code...
function convertColors2Process(){
 for (var i = 0; i < app.activeDocument.colors.length; i++){
 var myColor = app.activeDocument.colors[i];
 if ((app.activeDocument.colors[i].name != "") && (app.activeDocument.colors[i].name != "Registration")){
 if (app.activeDocument.colors[i].model != 1886548851){
 while(myColor.model != ColorModel.PROCESS){
 myColor.model = ColorModel.PROCESS;
 myColor.space = ColorSpace.CMYK;
 myColor.colorValue = [50,20,30,40];
Now, the color thumbnail changes to the new color, but again, when checking the color. It's still a pantone color with the old values.
No error occures when running the script and I'm able to change the color manualy in Indesign.
How do I change the colour mode of all spot colors to CMYK?
Thanx
John

Hi Larry,
I've tried using ...
function convertColors2Process(){
 for (var i = 0; i < app.activeDocument.inks.length; i++){
 app.activeDocument.inks[i].convertToProcess = true;
This will modify the ink manager to process the spot color as process color, but the color itself is still unchanged....
How do I modify any spot color to process color and change the colour mode to CMYK?
Thanks

How to correctly use spot colours in Photoshop?

Hi,
Using CS2, I've created one of those swooshy Macintosh Panther wallpaper images, with various layers of sweeping lines and tinted gradient arcs.
Now I want to create the image using just tints of pantone 519 but I'm unsure of how to work with pantone colours in photoshop. I've pulled up the solid coated pantone library and located the swatch, but how do I specify various tints of this colour?
I've searched the forum and come across spot channels, and have read the photoshop help entry on this, but still can't understand how to do it. From what I've read, I make a selection, then create a spot channel of the colour and set the solidity to 100%. If I want an 80% tint, I just adjust the solidity to 80%. Is this correct, or is the solidity more like transparency than tint?
In addition, how do I create a gradient between these two colours?
Final question - I have an element I want to import from Illustrator that uses the same spot colour. Do I have to deal with this any differently to the normal copy and paste as a smart object?
Sorry, I'm sure this is really quite easy.
Thanks for any help.
Steven

Why not just mode grayscale (or better yet a black and white adjustment layer, then mode grayscale), adjust levels, new spot channel, move dot from gray channel to spot channel? If it was made in RGB 519, your green channel is probably best to make the move to grayscale. If you're working in CMYK, then the magenta channel (unless of course you're using pictures with UCR/GCR).
 
 I guess I don't understand how you can say "I'll set it up best in CMYK" but can't get it to one color.
 
 Here's the tut version using the green channel only. If you do some channel mixing, I'm sure you could get something a little nicer.
