Re: Colour question
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. Bodvar Bjorgvinsson. On 6/10/06, Dov Isaacs <[EMAIL PROTECTED]> wrote: Lester is right!

RE: Colour question
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. Daniel Doornbos Technical Writer Promise Technology, Inc.

RE: Colour question
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.

RE: Colour question
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. Best wishes! Daniel Doornbos Technical Writer Promise Technology, Inc.

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.
