Does this work with Acrobat X?
are you PitStop Server_10 pach
Pitstop 10 should work with Acrobat X. For me it does
What is the best practice in Pitstop when ...
1. I have a PDF file with 4 spot colors e.g.
2. I want to convert 3 of them to CMYK.
Another way (doesnâ€™t remove the separation, just recolors the objects)
Preflight Profile > Spot Color Remap
BTW: I would prefer callas pdftoolbox for this task.
Oh you are so great!
But there is still one thing I have no real solution for. I need to convert colors (rgb) in ISO Coated v2 300% but the colors are getting really bad. I found a nice workaround.
RGB -> ISO Coated v2 300 = BAD COLORS
RGB -> Fogra 39 -> ISO Coated v2 300 = COLORS OK
With pictures in Photoshop that workaround is not a really a Problem. But is there a way to do this in PitStop? I only found convert to Device CMYK which in my case is ISO coated.
It seems that there is no way to choose another profile just for this intermediate step without changing my global color settings.
Set the colr management in Pitstop Preferences.
But to convert a picture that is already in CMYK to another CMYK color space, for example to get a lower TAC or to change the setting from coated paper to un-coated paper, a simple re-conversion in Photoshop with a simple different color profile is not the best way, because you'll make a double conversion: first from CMYK to Lab and then from Lab to the new CMYK, and as each conversion is not exact, this will make the colors change a little bit!
To convert a CMYK picture to another CMYK color space, it's better to use a "Device Link" profile with an in ink-optimisation sofware, like "CMYK Optimizer".
To change vector objects colors (texts, logos...) from RVB to CMYK (or from spot to CMYK), the best way is to change the colors manually, by remapping each RVB (or spot) color to a ben-day CMYK printable color with PitStop (or other PDF editor), because an automatic RVB to CMYK conversion with a profile will create most often CMYK colors using the 4 process colors that will be:
â€¢ difficult to print and to register perfectly,
â€¢ most often not plain, adding screening that will make strange results in fine objects, like little texts or fine lines and outlines.
- a RVB red 255-0-0 will be converted in a kind of C=1.18 M=96.08 Y=91.37 N=0.78 using the 4 process colors, while making a manual conversion allows you to replace by a simple C=0 M=100 Y=100 N=0, using only 2 process plain colors, much easier to print and avoiding screening!
- brown color are often automatically converted with 4 process colors, while it is often possible to replace manually by a 3 process color, using only MYK or CMY.
(I prefer to use MYK, because a CMY brown sometimes becomes a little bit purple...)
And in most cases, dark brown can be made at least with a plain Yellow, often also with a plain Magenta.
And the 2 last problems are the worst:
â€¢ the black: an automatic conversion with a profile will produce a CMYK black, something like C95 M83 Y82 K90, which is (almost) un-printable on texts, and will make the press-man become mad!.
Again, a manual conversion will allow to replace the RVB black by a pure C0 M0 Y0 K100 black (or a rich C60 M0 Y0 N100 black) easy to print and not screened.
(after the conversion, don't forget to make the black overprint!!!)
â€¢ the greys: an automatic conversion with a profile will produce CMY or CMYK greys, having all the problems of screening and registration, and adding the difficulty of a delicate grey balance!
Again, a manual conversion to a pure C=0 M=0 Y=0 N=x grey will be easier to print.
