best color settings for black&white


Recommended Posts

Given CS5 with SilverEfexPro and a HP Photosmart Premium desktop inkjet printer I save my M9 files via ACR in 16 bit TIFF files before editing them in SilverEfex.

How should I choose the Color Settings to get the best printing results?

Don't know, never heard of, are these HP-concepts? I do not know HP, at EPSONs we don't let the printer choose the color profile, should be put on OFF

Thanks Otto. Yes its for printing (HP Photosmart Premium).

But what about all the other settings, esp. Gray and Spot?

 

It should just be Adobe RGB. I assume the 'Gray and Spot' are HP concepts, perhaps best ignored if you want consistent results across the board, like if you emailed a picture in for a competition you would need to have used an industry standard colour space that reflects how you and they can both realise the same image. Using a printer manufacturer preset for your colour/B&W control means you can print a copy of that image how you like it, but they have no way to do it because they don't have your printer. Even more important though if you wanted to get a nice big image printed commercially, you can't tell the printers you used 'Gray' on your HP to get the tones you like because they will look at you rather oddly.

 

The other thing to consider, and especially as you are using Silver Efex, is that only very rarely do you see published photographs, or photographs in an exhibition, purely in greyscale, they are often at least tinted very slightly (like a subtle warm tone), or duotone. So to all intents and purposes your B&W image should be treated as a colour image if you do start to use tone for expressive purposes or to make the image more pleasing to the eye. And even if you do throw all colour data out and convert the image into B&W in pure Greyscale, you should at least convert it back to aRGB before saving the TIFF. Of course for web publishing convert your master file you saved in aRGB into sRGB.

Gray is colormanagement space for black, found within PSCS5. Spot is for solid colours used in printing, particularly offset printing.

 

I use gamma 2.2 for black to coincide with my screen gamma.

 

If Photoshop manages colour in the printing dialogue the you have to use a printer profile for the printer/paper combination.

 

Some people use a desaturated RGB image for printing B&W, then you dont have to worry about gray or spot.

You find 'Gray' and 'Spot' as options in CS5 'Color Settings'.

 

But they are niche settings, not a wide industry standard, so my points still apply. While part of the same language they are more akin to a dialect that not many people will understand or be able to use in translating your ideas.

Just to drop my coin ...

 

I always go for the best processed COLOUR photo, then go to SEP and convert to B&W. For printing, let PS (or LR) do the thinking and don't fiddle with grey and spot.

 

Oh, and read up about RIP's. That'll help you with printing. Lots about it on the forum.
