RGB to CMYK

If the company had a professionaly designed corporate identity, they should
have spec'd the colors for you in both CMYK and probably Pantone as well.

Picking the colours from your monitor is not a reliable way to match the
colors.

The covers will never match. CMYK and RGB are different color spaces. You
can select a color, though, then using the palet pull-down choose CONVERT TO
CMYK. That will at least save you time.

Again, though, if you are trying to match a corporate Identity, you need to
get the original spec'd colors.

Hi Everyone :b

I created a design in FH. All the colours are RGB. (i colour picked the
colours from the company's corporate id)

Only problem is that this design will be printed as CMYK. I can convert the
RBG to CMYK (by sliding the colours bit by bit), but this takes lots of time
and the end result colours doesnt always match!

Is there an easier way to do this?

thx

Thanks Darrel.. u cleared things up alot!

If i create a design and colours from scratch.. and the design will go onto
cmyk print.. wot wud be the best way to ensure that colours on the screen
and on print will be the closest match?

is there a cmyk palet that i can choose the colors from?

what is the use of the default rgb colour palet if rgb is not meant for
printing? this confuses me

thanks again :)

How can I convert from RGB to CMYK in elements? Or turn a TIFF or PDF into CMYK?

Rich, while you're here, I have a related question that I've been wondering about. We are thinking of investing in Xerox 7700 for my music publishing company so that we can do short runs inhouse.

We do monochrome about 27 or 28 times as much as color, but I've been wondering about printing those rare color files on a printer like that. Will the result in rgb mode be as yucky as the photoshop forum says it will?

Barbara,

I wish I could be more help, but I'm not familiar with that printer.

What I can tell you is some high end printers contain an internal rip device. For instance sending to a docucolor through a rip device like a Fiery will do the conversion at the RIP and you actually get a better result sending RGB because the device does its own conversion.

If you are looking to do short runs in house you might want to move to full photoshop. It may be a worthwhile investment when looking at it from a business perspective.

Yes, we know we will eventually have to, but were hoping to tough it out till ID 3, since we need the full design bundle, Rich. Thanks.

please forgive me for this seemingly idiot question but to convert my RGB graphics to CMYK for the print house do I just convert it through the mode button or is there more to it ? The help section really does not tell me if i need to do anything else. Are there other settings that I need to monkey with ? Thanks, try not to laugh too loud at me~ Jodi

In it's simplest form, yes, all you have to do is convert from RGB to CMYK through the mode menu.

A couple other "considerations" if you will, that you may want to take into account, are:

The first would that you should expect to see some color shifting as a result of the process. Reds will tend to look more brown and blues can become more purple. A good way to simulate the end result while working in RGB is to work with the CMYK preview on (Ctrl + Y). At least with this on, you won't be surprised with any color shift and can correct it long before it may become an issue.

A second thought is that if you work on a color managed system at all, consider the CMYK profile you choose before converting from RGB to CMYK. I tend to use the US Sheetfed Coated v.2 profile, as most of my work is printed on sheetfed offset printers using a coated paper stock. I get some excellent color results on the final product.

What I would suggest is to identify A] what kind of press the project will be printed on, and B] what kind of paper. Then make sure you talk to your printer to see if he has a specific color profile that he would prefer you use (some presses do have specific profiles that can greatly help with the final output quality). Also check with the printer on the amount of dot gain that is typically associated with his printing processes. That way you can accomodate for the gain within the color settings of your file.
