Digital BW, The Print

Hi Ben,

Assuming you use a set up as described by Jimbo :

When softproofing in PS are you checking the Paper White and Black Ink boxes ? Is you lighting booth dimmable and strong enough to compare to your screen when the screen is adjusted to 80( or max. 100 ) Cpsm ? In my opinion with a proper setup a white document soft proofed with a good QTR profile ( checking Perceptual with BPC and Paper White and Black Ink ) using a good monitor profile ( gamma 2.2, 80 Csm, white point of your booth, 5500 K in this case, if the bulbs are good ) must match the paper used when you adjust the booth ( not the screen ) for the same intensity of your screen . The color of the paper and it's luminosity will be well represented .

Am I missing anything ?

Hi Jimbo,

I made up a linearized printing curve in QTR, customized to my printer and custom inks. Then I converted this profile to an icc profile. I can use this icc profile in Photoshop or in Eizo Colornavigator to emulate the printing environment. The problem is that the screen is too bright and the paper is very low contrast (matte). So, it doesn't make sense to use soft proofing if the screen contrast is 4 to 5 times higher then the paper I am printing on. That's why I wanted to find out the best screen settings to come close to the paper's specifications (white point, contrast, etc..).

Today I found these articles that describe very well what I want to achieve:
(but it doesn't give a complete answer to all my questions I still have)

Hi Ben,

I went back and read your first post and this one a couple of times.. I think I get what your trying to do but I think that the way the hardware is designed to work you really can't get there with this path.. I am not very gifted with words so hang with me..

Our monitor is an RGB device. The white point we set is a hardware white point that is intended to match a viewing spectrum in this case 5500K .. ..The key here is to realize that when you view B&W on your monitor your monitor is emulating it using RGB technology.. In my mind when you drive the white point to a setting that you feel matches your paper white your throwing a wrench into the works.. The proof of this would be to use the soft proof process in PS which now would not work properly.. It seems your trying to "manually" adjust the monitor to meet a single viewing experience.. Yes you may succeed at achieving the visual for this one particular instance but then wouldn't everything else be incorrect..

So how about a different path to get there..Maximize your hardware to its design intent setting the white point where it should be for 5500k and them build a great profile for that device.. also required will be a printer profile that you feel delivers the bacon for your printer.. When viewing this in the soft proof process in PS if you feel that it is not representing your visual of the print your looking at.. You could then take your monitor profile make a copy of it (The software I use does this automatically in a profile adjustment module) and adjust that profile to match your visual.. Save that profile then your done..

In my mind if you start screwing around with hardware settings it would be to easy to get lost.. I feel that if you have a proper profile for your monitor and also a proper print profile... these are foundation items that you can stand on and get back to.. If you make a copy of the monitor profile and adjust it your in a better position to get to the other side... also it makes sense if you want to print on a material that has a different paper white..

Maybe I'm missing something is what your up too ...if so I apologize for derailing the train..

Hi,

I have set up some tests, and they look well but I want to double check if I can improve them.
I work/print in black&white, so greyscale mode.

So I have done this:

I made an emulation ICC profile

I didn't check the 'preserve RGB numbers' option

I choose 'perceptual' for rendering intent

Then I created a new target

I have set the brightness as low as possible (to match the matte paper) > I have set it to 60 cd/m² > If I want to go lower I get a message > Which brightness setting is the best??

I have set the white point to 5500K "daylight temp' > because my "lighting booth" (Kino Flo lamp = 5500K) (By the way, I have some questions about the use of this booth too)

I have set the target black level to the minimum (is this the right value?)

I have set the priority to 'gray balance' (not sure if I should better choose 'standard' or 'contrast'.

Soft proofing is of course possible in Photoshop, but as I see it now, it seems to be much more effective by adjusting the monitor (low brightness, exact white point, ...), and the ICC profile emulation seems to working well.
(but still it is not completely configured well if I compare the prints with the monitor > is this possible anyway?)

Thank you for your help and advice.

Ben

Hi Ben,

Could you precise what kinds of settings disturb you ?

Hi,

Has anyone -advanced- experience with setting up soft proofing for
black&white printing by using ColorNavigator for Eizo Coloredge monitors?
I tried to set up some targets/emulation profiles for printing on matte
paper (Canson Rag Photographique), but I am still in doubt about some
settings.

Thank you,

Ben
