Also note that CMYK can very seldom match Pantone or vice versa -- or
whatever other color scheme that is based on pigments added to some
base ink. So if you want an exact Pantone color, make that ready in
some spot color and tell your printshop what exact Pantone (or
whatever else scheme that the printshop has their ink in and you have
agreed to use) number to use.

The printshops' approach is to either get a prefabricated [Pantone]
color ink or make a blend from some basic color inks according to a
Pantone color scheme.

There can also be other things to consider that may affect the final
color, mainly the paper of material to be printed on, its own color
(not all whites are like), etc.

For a final near perfect solution, try to find the best
printers/printshops and talk things out BEFORE you prepare any final
output. Otherwise you may end up with a lot of extra work.

Just my experience having worked at both sides.

 As has been repeated in this forum, time and time again, if
 you are 'printing' to PDF you should be using the Acrobat
 Distiller print driver, and not the drivers for any specific
 real or generic device.
 This should show up in your system (Windows) as the Adobe
 PDF or Acrobat Distiller (if you have an older version of
 Acrobat) printer.

 While you may not have any immediate problems, there is the
 strong possibility that the resulting PDF will not be
 compatible for all devices, or suffer from other problems
 which will rear their ugly heads at the most inopportune
 times such as 15 minutes before a critical deadline.

 And I am not convinced that the printer drivers in Windows

 what the Windows GDI (Graphic Device Interface) uses as it's
 default color space.

Colour question

2006-06-09 Thread ETudsbery


I'm trying to create some colours for a FrameMaker template which
correspond to our corporate style guide and I'm finding it rather
difficult. One of our corporate colours is Pantone 2627 which is a dark
violet. When I select Pantone 2627 in the Colour Definitions dialog box, it
does indeed look violet on the screen, but the CMYK values for Pantone 2627
(83C, 100M, 0Y, 23K) correspond to a blue -- and this is the colour I get
when I generate a PDF or print to a colour printer. Any ideas what I'm
doing wrong?

Thanks for any help.

RE: Colour question

2006-06-09 Thread Daniel Doornbos
Dear Edwin,

Pantone and CMYK are two completely different color (colour) schemes.

A printing press operator can either buy ink in a specific Pantone color
or mix the ink from an exact recipe of colors and proportions. People
use Pantone color when they need an exact color. Pantone colors are
designed for offset printing.

CMYK, which stands for Cyan, Magenta, Yellow and blacK (or Key), also
known as four-color process, is a system of printing rosettes
(overlaid dot patterns) in these four specific inks. People use CMYK for
photographs or when an approximate color is acceptable.

In your case, it sounds like the problem is the fact that you are
outputting to a color laser printer. Laser printers use CMYK toners, so
the color is only approximate. You did it right, the printer did the
best it could.

When you print to PDF, you use a printer driver, either a specific color
laser printer or a generic driver. These drivers use CMYK color as well,
so again, you are left with an approximation.

If you are printing something that requires exact color, such as Pantone
2627, the best approach--assuming there are funds available to pay for
it--is to have the project printed on an offset press. If you choose
offset printing, be sure to check with your printing company as to how
you should prepare your files for color separation, that is, which
elements print in black, which print in Pantone 2627, and so on.

If you don't have the money for an offset print job, you could
experiment by specifying different Pantone colors, to find one that
prints closely enough on your laser printer or PDF. If you can, borrow a
Pantone color bridge booklet, which shows each Pantone color beside a
CMYK approximation. Visit the Pantone website at http://www.pantone.com
and look around.

Bear in mind that Pantone system was designed for ink but laser printers
use toner, so the actual results will vary somewhat.

RE: Colour question

2006-06-09 Thread Daniel Doornbos
Dear Lester,

When you send a PDF file to an outside firm for printing, such as I
suggested for Edwin's project, your choice of printer driver can make a
big difference in output quality. The Adobe PDF driver is good when your
PDF is the final deliverable in the project, meaning it will be read
online or the user prints it.

But if your PDF is the means of transmitting your work for film or a
high-end digital printing press, the Adobe PDF driver may not give the
best results. I learned that lesson through hard experience. That is why
I urged Edwin to talk with his printing company before outputting his
files. They will know the best way to prepare his files for their
process.

Printer drivers do not use CMYK color. The driver is required by the
Windows OS in order to have a target to which you can print. The
printer, whether inkjet or laser, is the device that applies the CMYK
color.

CMYK is a subtractive color model, based on color as reflected from a
surface, such as a printed page. RGB is an additive color model, based
on color coming from a light source, such as your computer screen.

RGB graphics are designed for display on computer screens and
projectors. That is the reason the Windows GDI uses RGB. If you send RGB
graphics to the printer, the printer (or, in the case of inkjets, the
software) must interpret and convert the data to CMYK, because those are
the colors the printer can put onto the paper.

In most cases, the members of this forum probably are not involved with
offset or digital printing of their projects. As somebody who has worked
in that area, I will share my experience and let the readers decide for
themselves.

PDF is the final deliverable in the project, meaning it will be read
online or the user prints it.

But if your PDF is the means of transmitting your work for film or a
high-end digital printing press, the Adobe PDF driver may not give the
best results. I learned that lesson through hard experience. That is why
I urged Edwin to talk with his printing company before outputting his
files. They will know the best way to prepare his files for their
process.

Printer drivers do not use CMYK color. The driver is required by the
Windows OS in order to have a target to which you can print. The
printer, whether inkjet or laser, is the device that applies the CMYK
color.

CMYK is a subtractive color model, based on color as reflected from a
surface, such as a printed page. RGB is an additive color model, based
on color coming from a light source, such as your computer screen.

RGB graphics are designed for display on computer screens and
projectors. That is the reason the Windows GDI uses RGB. If you send RGB
graphics to the printer, the printer (or, in the case of inkjets, the
software) must interpret and convert the data to CMYK, because those are
the colors the printer can put onto the paper.

In most cases, the members of this forum probably are not involved with
offset or digital printing of their projects. As somebody who has worked
in that area, I will share my experience and let the readers decide for
themselves.

As has been repeated in this forum, time and time again, if you are
'printing' to PDF you should be using the Acrobat Distiller print
driver, and not the drivers for any specific real or generic device.
This should show up in your system (Windows) as the "Adobe PDF" or
"Acrobat Distiller" (if you have an older version of Acrobat) printer.

While you may not have any immediate problems, there is the strong
possibility that the resulting PDF will not be compatible for all
devices, or suffer from other problems which will rear their ugly heads
at the most inopportune times such as 15 minutes before a critical
deadline.

And I am not convinced that the printer drivers in Windows use CMYK -
they may, but they may also just use RGB which is what the Windows GDI
(Graphic Device Interface) uses as it's default color space.

Colour question

2006-06-09 Thread Dov Isaacs
Lester is right! And also be aware that NO, repeat NO,
repeat yet again NO Windows driver, whether PostScript
or otherwise, can accept CMYK from applications, except
for EPS passthrough with the PostScript driver, since
the Windows imaging model is totally RGB. Drivers can
output CMYK (as the PostScript driver does), but since
the input to the driver is GDI and GDI is totally RGB,
in general, an application program cannot communicate
CMYK directly to a print driver. This includes FrameMaker,
with the exception of EPS passthrough.
