Missing profile message in Photoshop?

in color settings (edit menu) uncheck ask on opening for missing profile

 

Yes that will turn the message off - just set your profiles to what you want to use (Adobe RGB 1998 for RGB, SWOP or whatever you like for CMYK etc...then when a unprofiled file gets added, it will set itself to your pref's) Hope that makes sense. The only reason for that message is so you KNOW that there is no profile embedded...

 

i assume most files are supplied to me as sRGB ... i use adode 1998. so you can't assign the adobe1998 profile to an sRGB image without messing up the color. always honor the embedded profile , open in PS and then convert to your working space. if there is no embedded profile and it is not your file it is probably sRGB... if you created the file and your settings were adobe1998 then you need to assign that profile.

so the message my be a help to you... so you will know what is going on with the color management

 

Long story short - Make images & profiles based on CMYK. That is what the printer prints with.

 

This is a debatable subject...

 

Of Course!
I choose CMYK because the printer prints with Cyan, Magenta, Yellow & Black. Why leave one or another units (aside from calibrated monitor) or rips to interpolate RGB along the way to the printer? ...That's my logic, which of course many won't see any in it, but we'll take that up in NHB some day!

 

The CMYK profiles for Sheetfed and Web Offset Printers are much smaller than what can be achieved on inkjet printers.

Working in CMYK using the existing profiles in photoshop results in a smaller available gamut.

The press profiles are based off of SWOP standard inks. We use much brighter pigments with inkjets.

 

Highly!

The best way to find out for yourself is to have a bit of a play. I did this a while ago with some gradients with say blue at one end and green at the other.

Print it on your printer using each of the different colour spaces and you will be amazed at the results and will see the different colour gamuts in each of the spaces yourself.
