Lee,
In regards to the Spot Color Table feature of Onyx Postershop, as you
know if the name does not match the name used in the table then Onyx
will use your Input Profile as source. When adding names to the table,
name them exactly the way they are named in the program, not the generic
way Onyx is referring to them as "SpotColor 300 C" The ending of the
name can invalidate a match in the table, some are "C" some are "CVC"
and you can simply make an alias in the table to the various iterations
of the endings. To match up CVC call it Pantone 300 CVC, make an alias
of this to the table color called Spotcolor 300 C.
I believe you said you were using a profile supplied with PosterShop
called Better RGB. I am not familiar with that RGB space, I've had good
luck using Adobe RGB or something even larger in size.
If you want to confirm that the RIP is actually using the Table and not
defaulting back to your input profile you can access the RIP Log from
PosterShop RIP Queue v5.6.1. You will need to highlight the file name in
the Queue and then a button becomes available for selecting which is
called RIP Log.
If the log says that a Pantone color is not available using default
color, then it means that the Table has been by-passed and is using your
input profile. If it is using the Table then no message in regards to
Pantone colors will be present.
You said you were attempting to hit Pantone 300, this is a bright blue
and according to my Solid to Process comparison Guide this is not a
color that can be matched with SWOP inks. However you are using Inkjet
inks and you mileage will vary; media type and finish will also come
into play.
I have had success with my Colorspan Printers hitting some of these
brighter colors but sometimes I still need to do a custom build to
achieve the results I'm looking for. PosterShop does have a color
replacement feature that works great with vector colors, you sample the
offending color and then you type in the change you want to make, for
blues you are usually pulling out some of the yellow which is dirtying
up the hue and adding cyan if there is still some room to move.
I checked the Onyx web site for PMS charts and they are no longer there,
not that I could find anyway, also they are no longer on the 5.6 install
disks. They may be on previous install disks as they used to come with
more sample files then 5.6 is providing.
I have a chart that I could email you that I got from Onyx, or you might
call Onyx and see if these charts are on their FTP site which they can
grant you access to. The charts are free.
