Sending spot color separated art to DPM, can 1 color be sent lighter?

I have a two spot color PDF (black and a PMS green). The photos are grayscale and look fine on the screen but when I send it to our DPM and look at the preview there, the photos are super dark. The text is in 100% green so I really dont want that to lighten but was hoping that somehow when sending it over, the blacks are sent at a lighter shade or more screened or something. There are some options in the Ink Manager when going through the print dialogues that I am not too sure what they do. One is called "Neutral Density" that sounds like it might be something like this but I cant tell where it does anything. Is there anything I can do to make what appears on the DPM looks more acceptable and not overly dark?

IMO, you won't get this answered in the Acrobat forum.
Without discussing embedded profiles in the images...if you're hesitatnt about photo's because they print to dark, your wasting the functionality of that DPM. Any decent daylight camera will print line copy at half the materials cost...
I would suggest you have a tech spend a day in the pressroom to calibrate the DPM. We brought one in for 30 days and sent it back, I get better results through a small imagesetter (which is really all your DPM is with the addition of a RIP and material cutter)
You will probably get the best answers here

In short, there are some test files stored hopefully on the RIP's internal drive - test patterns. Pull one up, plate it, run it on job stock at normal ink levels. Measure the screen values. Input these values into the RIP's calibration sets.
If you were to create your own - Create twenty .5" x 4" frames, fill them with tints of black from 5% thru 100%, plate it run it...I'm guesiing that everything over 75% is filled solid

BINGO!
You can't migrate the Final Cut Studio apps. They install bits and pieces all over the system folder and libraries. if those files are missing, the apps can't work properly. That's your issue.
use FCS REMOVER from digitalrebellion.com (free) to uninstall FCS 3, and then install again from scratch, and update with the Software Update.

View Spot Color Separations in Reader

Is there any way to view the spot color separations in reader?

No. That requires the Pro version of Acrobat.

Can you think of a nifty trick to work in grayscale, while previewing in real-time a 2 color separation?

I need to come up with a procedure that allows a customer to work on a black and white image while assessing the effect of a translation into a 2-color separation.
To visualize what I’m looking for, place a grayscale image in the magenta channel of an empty (white) cmyk document, and the same grayscale image inverted into the yellow channel. The other 2 channels stay empty (white).
Now we have the white end of the grayscale expressed as yellow, the black end as magenta. Since one channel is a direct inversion of the other, the sum total of the 2 is always 100% at any point along a gradient.
I have written a action, that allows one to quickly look at the effect, but what I am being asked is to is to deliver the same thing in real-time.
Duotone? NO!
In a duotone document I can only move one curve at atime, thus creating overlap (too much red) or a gap (whashed-out hue) between the profiles of the 2 curves.
CMYK? NO!
In a cmyk document I have the option to move 2 curves simultaneously, but what I would need is an option to work one curve, while the other automatically moves equally in opposite.
Gradient mapping?
Here I have a rudimentary way to set the starting, mid, and endpoints, but it needs to be done in RGB and I don't know of any way to separate the resulting RGB channels into a grayscale that maintains all the information.
Anyone? Any ideas are much appreciated.

Mars Red,
This might work. Assuming you now have a CMYK document, with no cyan, no black, and magenta and yellow are inversions of one another
1. Create a solid yellow fill color layer on top, blend mode normal 100% opacity
2. Create an empty layer on top of that, blend normal, 100% opacity.
3. Select all, fill this layer with solid magenta
3. Hide this and the yellow layer
4. Load the magenta channel as a selection
5. Click on the solid magenta layer, Layer - Layer Mask - Hide Selection
6. Show all the layers
7. Click on the mask on the magenta layer. You can apply curves to this mask. No matter what you do to the mask, the yellow separation will always remain an exact inversion of the magenta. You will always have 100% ink coverage in every area, no more, no less. The only catch is the mask is opposite the ink, so curve adjustment is opposite of ink behavior.
That is CMYK solution. Here is duotone solution, much simpler:
Assuming you have a grayscale image:
1. Mode duotone
2. Type duotone.
3. Ink 1 : color picker, CMYK, 100M (yields name Magenta)
4. Ink 2: color picker, CMYK, 100Y (yields name Yellow)
5. Ink 2 curve: 0 = 100, 100 = 0 (inversion)
6. Hit enter. Now you can make curve adjustments to the duotone channel (not the duotone curves) using Image: Adjustments: Curves. No matter what you do to the duotone channel, you will maintain inversions of magenta and yellow, and you will always have 100% ink coverage in any given area.

How do I attain color separation in InDesign that containes Photoshop Images?

Thank you for your time.
I have to submit an ad that will print black with spot color (Cyan). Below (Image 1) is the ad that does not contain color separation. The publisher said that I have to provide an ad that allows for color separation, without the ad being changed. Below (Image2) shows how the ad changes when I apply the color separation, with only Cyan being selected. I have also included (Image 3) my color settings; I'm not sure if my color settings have a part in my ad changing. If you know what I need to do to fix this issue, I would greatly appreciate your help.
Thank You.

If your ad contains only Black and Cyan inks you should be able to send the composite PDF and it will separate in the RIP at the publisher. If this is not waht the publisher wants, you need to get verys specific instructions from them. We can help you to understand those instructions if necessary.
The key here is that your images must be true grayscales or Black/Cyan duotones and you must not use any 4-color black elsewhere in the ad. Looking at your screen shot of the cyan plate it looks like the images are grayscale and OK, but your background gradient and black caption bars are showing cyan ink, so unless you used a cyan/black with no magenta and no yellow in them you have a problem. RGB colors cannot be used here.

Color separation when exporting a PDF

It's been driving me nuts, ADOBE seems to have forgotten about color separation when using the export to PDF method. Even quark has this option.
Anyway I was hoping to know if there is a way that I don't know.
Cheers

You’re asking for fairly archaic things here.
You can put in a feature request but you’d need to explain how this would benefit the entire user base and IMO you’re going to have a rough time doing so.
Bob, it might be archaic, but it's still used a lot in the publishing world.
in the book world, the new trend is for firms to do books in a co-edition format. The idea is to have one firm do all the work (normally in english). But then other firms from other countries and other languages will simply send a PDF of the text ONLY without the colors (cmyk). So when I export the PDF I only need ONE color. I do not wish to export the whole CMYK.
Do you understand where I am getting from.
So in simplified terms. The printer has 4 plates for the colours of the book and will simply change a 5th plate to the desired language.
5000 copies
CMYK plates
5th plate: german text
10 000 copies
French
exactly the same CMYK plates as german
5th plate: switch to the french plate
50 000 copies
English
exactly the same CMYK plates as german
5th plate: switch to the english plate
and so on....
The cost is greatly reduced for everyone, but we need an option to export the TEXT only.
You will simply say, but have the text in a separate layer. That is true, but in reality, it's not all the files that are built like that and most graphic designers will have the text on a separate spot color instead of a separate layer. Unfortunately when I receive the file it's too late to do the changes.
I hope I make sense, english is not my first language.

Color Separations When Using "Print Booklet" feature

My document has a 2-color logo (black & spot PMS 485) and a 10% black screen on it. When I make a pdf using the export to pdf everything breaks out correctly. When I use the print booklet feature and "print" it as a pdf or postscript it changes some of the black in my logo to 4-color black. It also changes the 10% black screen to 4-color. I've tried just about every setting I can think of and can't seem to get it to break out correctly.
The below images show what I'm talking about. The top part of each image is the original InDesign file. The bottom images are after they have been inserted into the print layout. The one on the left shows with all colors shown and the one on the right shows the black turned off in the separations preview. You can see on the bottom of the right one the black screen is still showing and the black in the logo is also because somehow they have been converted to 4-color.

In the Print dialog make sure Output>Color is Composite CMYK, Graphics>Send Data is set to All, and Color Management>Printer Profile is set to Document CMYK.

Color separations with Snow Leopard?

Before installing Snow Leopard I was able to create PDF color separations by going to file > print. From there I changed the printer to Adobe PDF 9.0 and changed the Mode to Separations under Output. When the print button was pressed I would get a PDF file with all my CMYK and spot colors on separate pages in shades of black. This is the file I need to send to have negatives/plates made.
With Snow Leopard the print to PDF command no longer works. I can still use Save As PDF, but that would require me to manually remove all colors except one and then change that one to shades of black. That process would need to be repeated for every color used. Does anyone have a work around or better way to create color separations? I have contacted Adobe and have an open case working this problem. There is currently a bit of confusion because the individual at customer support thinks I am having trouble printing color separations when I am actually having trouble saving color separations using the print command.

Here is the work around!
Print the file to a .ps and run it directly through Distiller you will need to give Distiller your password.
That suggest to me that the problem is that distiller needs to pass word in order to save the file anywhere and not be able to do so without the password it just sends it back to the system after completing the distilling when you try to print to pdf.
Here is two of the four pages I got from my experiment
Not ideal work flow when you are doing a lot of them but much the same we are all use to doing it in the past.
Most important it is a way.

Color Separations in InDesign and Illustrator

I am trying to print spot color separations. In both InDesign and Illustrator the "separations" is gray. I can only print RGB and grayscale.
My colors are set up as spot. I even tried to print from Acrobat and "separations" is gray there also. Do I need to re-install my drivers or the programs.
I am trying to print to postscript printers but neither one lets me select separations.
I am using CS3
Microsoft Windows XP
Professional
Version 2002
Service Pack 2
Intel(R) Core (TM)2CPU
6600 @ 2.40 GHz
2.93 GB RAM
Thanks in advance for your help.

I’m not familiar with those models. Are the PostSCript compatible? If so, then you should get the most recent drivers from the manufacturers’ websites. It’s been ages since I needed to worry about printer drivers in Windows, but maybe you need a PostScript printer utility or printer driver from Adobe, too.

InDesign / Color Separations / BW Laser printer

In the past, I have always used an old HP Laserjet 4MV/PS for our spot color separations from Pagemaker. Most InDesign (CS2 & CS3 / PC) files are too big for it to handle, so we create pdfs and output that way. The 4MV has now died and we want something that outputs a better quality dot pattern and separations to paper for grayscales/shading. I don't need high volume, but do need at least 11 X 17 and only need it to output black. What printer will handle large graphic files and provide a good dot pattern?

The printer in question, the Brother HL-4570CDW, is a fairly inexpensive SOHO laser printer typically used to print “office” documents. As such, it doesn't offer direct options either on the front panel or via the driver to match typical commercial print conditions such as SWOP. Most content sent to such a device is sent as RGB from printer drivers.
(For your convenience, I have attached a copy of both the specification sheet and the manual for this device!)
Some ideas:
(1) Don't expect reasonable CMYK colors if you are using what Brother describes as the “Windows(r) printer driver (the most suitable printer driver for this product)” and what is apparently installed by default (see page 26 of manual). It invokes an emulation of HP PCL5C, pure RGB, which is a real problem from InDesign. Install their “BR-Script printer driver” and turn off the option for RGB vivid color and try that instead. BR-Script is Brother's emulation of PostScript 3 - definitely not Adobe PostScript 3, but it possibly will give you better results than their emulation of PCL5C!
(2) Assuming you are printing BR-Script and the colors are still very problematic, try recalibrating the printer via the printer's front panel. See page 82 of their manual!
(3) Export PDF as PDF/X-4 and try printing the PDF/X-4 file from Acrobat Pro or Adobe Reader, again using the BR-Script driver. This might improve things.
If you still can't get decent color and the printer is still “new,” I'd try to return the unit as defective. You can get much better printers for comparable prices from Xerox that have Adobe PostScript 3 and have reasonably good color. Otherwise, if still under warranty, I'd contact Brother and see if they have solutions other than blaming Adobe somehow!

PS: This isn't the first report I've heard of serious problems with Brother CloneScript devices.

How do I save color separations to a larger size than my printer will allow?

I have an Illustrator file from which I'm trying to produce color separations. What I want is a PDF with each separation on its own page, but it looks like you can't export separations to PDF directly, so I'll probably export to PostScript and use Distiller to produce my PDF. I only have an 8.5"x11" printer, but I want the separations to export at 15"x16" to be printed elsewhere. But Illustrator won't let me unless I have a PPD installed for a printer that can print to that size. That seems dumb... I have no idea what printer will be used to print them, and I have no idea what model printer can print that large. So what should I do? Can someone point me to a PPD that will allow me to export to 15"x16"? Or is there another way?

I just tried a quick test using save as pdf and according to the print dialog box in acrobat that spot colors are there. Perhaps you are using one of the presets that converts colors.
In the save as pdf options dialog box look at the output section for color conversion and see if it is set to no conversion. some of the standards change this setting.

Need help with color separation

Hi
I just sent my pages document to a printer to make copies. It will be printed by an off set printer. They called back and said that I need to convert my CMYK file into a spot color for color separation to use pantone inks. Can this be done and how??? I have pages 1.0.2.
thanks

I was hoping to use this program for layout work (thats what I thought it was for, if a printer can't use it, what's the point!Why do they have all those brochure templates if they can't be printed, or am I using the wrong type of printer?).
Pages can output CMYK files just fine, which is what most brochures and similar documents would use (many of which, as lo_tech suggests, would be printed digitally). But Pages is simply not a high-end, professional page layout tool suitable for doing more complex things like using Pantone spot colours in separations. That really is the domain of specialized pro products like Quark XPress and Adobe InDesign.
That said, I would think your printer should be able to do a four-colour separation of the file you've provided. I may not be clear on what their objection is, but it sounds like they simply don't want to produce four plates for the print job, and instead want to only do two. I suppose that's understandable from a cost point of view, but even if the file has a narow colour range, it should still be possible (even if a bit more expensive) to do a CMYK separation.
The other option is as lo_tech suggested, and print it digitally. For short runs this will be cheaper than offset by quite a bit, although offset really benefits from economies of scale, unlike digital printing.

Exporting to pdf with page marks and color separations

Hi All.,
I have a requirement to export the current document as PDF file. I am using the export provider with the service registry to export the document as pdf file. The code works successfully. Now I have a requirement where I need to save the pdf with color separations and page marks. First I need some information on what does page marks and color separations actually mean for a pdf file. And second I need to know how this could be achieved. Do I have to set some preferences? I have tried setting preference for color , bleed and it works. But I am not sure whether this satisfies the requirement. I would be thankful if someone would suggest me on the same.
Thanks in Advance
Vishnu

Hi,
In my experienced it cant, you can export it to pdf but you dont have the ability to make it fillable, unless doing it manually, from the exported pdf, install an Adobe Professional software to have capability to save data's.
Regards,
Clint

Color Separations Problem in Acrobat 8/9 Pro

We recently discovered a color separation problem in Acrobat 8 Pro and 9 Pro. In version 7 Pro we could select and thus include 'empty' color sep pages. Now when we select seps of the all the available colors, seps are produced only for those colors actually used in the job. This is true of pre-separated and in-rip seps. Can anyone shine some light on this 'change'? Thanks!

We are able to reproduce color saturation problem at our end. We have noted down and will work on this.
Thanks.
