Are the ICC profiles for Printer & Adobe the same?

[tonymaclennan]

Just wondering, if photoshop manages colours, sRGB for example then when its sent to printer will it use the sRGB settings as per the profile on the computer or does it use one from the printer?

As i'm wondering, if you send to printer with a source or sRGB and output as sRGB then could for example the output ICC file be corrupt and causing differences in colour?

Thanks

yes, thats why i said turn off colour control in photoshop and let the printer manage its own colours. Photoshop should override the printer in colour management unless you tell it no colour management

I tried toggling between 'application manages colour' and 'printer manages colour' many times. Output is slightly different in that the former, the pinks coming out grey and the latter making pinks orange. Red to orange.

So in theory... if I set printer to manage colour: convert to profile: sRGB --> Print with Preview --> Select sRGB in output then the results should be the same? (assuming monitor calibration is spot on) ??

Still sounds like colours out of gamut to me.

the only thing i can think of is, leave printer to manage colours, on the print properties on screen go through the different papers ie print one canvas then one with plain paper properties and so on, see what results you can get just print small pictures but on the same material(in the machine) hope this makes sense. one of these may work and youll have to stick to using that profile. Apart from that im afraid i cant help much more sorry.

 

[Correct Color]

Actually, sRGB is a color working space, not a printer profile. The terms overlap a little bit but they're not exactly the same thing. No printer is ever going to print correctly if you use sRGB as a destination print space. If you want to print correctly from Photoshop, the first thing you need to have is a good ICC profile of your printer, printing in the resolution you're using and on the media on which you're printing.

Then, your image may be in any of several 'working spaces', such as sRGB, or Adobe 1998 RGB, or ProPhoto; and your goal is to get a conversion from your working color space to your printer color space (ICC profile) while keeping as faithful as possible to the colors as they exist in your original color space.

You do this by telling the printer to shut up and do as it's told--hopefully the instructions are in the driver somewhere--and by having Photoshop manage color, and selecting your printer profile as the destination color space (ICC profile).

Of course understand that unfortunately a valid ICC profile isn't necessarily a good ICC profile. Making printer profiles is an art, and there are a lot of downloadable profiles out there--even from some pretty well-thought-of media, ink, and printer companies--that just aren't very good.

Still, the path outlined above is the only way to do it correctly, and how much time and effort and money you put into getting a professional-grade color workflow is entirely up to you.
