Book Design and Imaging

What percentage lighter should I make my B/W images?

I have searched this forum until my finger tips bled. I have read all the Adobe Gamma, ICC Profile, and various other software methods for calibrating my monitor. Most (maybe all) of them dealt with color images. All mine will be B/W. I’m not a perfectionist, but I would like the images to reproduce nicely (obviously). I’m sure in the priniting of the book, the images will get darker… almost a given. So, knowing this, someone please just give me an idea about what percentage I should lighten my photos (I’m using a Macbook Pro set at the factory calibration and brightness turned up so all but three of the boxes on the brightness display light up). As you can see, I am not Mr. Technical. I am using Lightroom to manipulate the exposure of the images. So if an image looks just the way I like it on my monitor (using the high-tech specs I just mentioned), about what percentage should I lighten it.

Thanks!
Michael

This has nothing much to do with b&w.

I hope you realize that there is no consitently reliable way that you can use your eyes to properly calibrate your monitor.

In addition, the laptop screen you are looking at changes the apparent image darkness when you alter the viewing angle (mine does this) .

 The best you can hope for on that laptop is a reasonable targeted printing ONLY IF you have used a monitor hardware calibration device. AND are viewing the screen AT the proper angle. You are better off with a properly calibrated desktop monitor BUT it can be done with that small screen, but likely not on a first printing.

You might be somewhat in luck, I note that X-Rite is offering a free laptop screen calibration: http://xritephoto.com/

Wow! The best I can hope for even WITH a hardware calibrated monitor is a reasonable printing! Maybe Blurb isn’t for me. I would think all the variables you mention (room darkness, viewing angle) would be an issue even with a hardware calibration.

Thanks for the link. The nearest dealer is 3.5 hours away, but it might be worth the drive!

If you look at this post http://forums.blurb.com/forums/10/topics/8249#posts-35099 you’ll find a workflow to produce high quality black and white printing. However I can’t emphasise too much that you must have a properly calibrated monitor in the first place. I have used this in all my books and I am more than happy with the results. You do have to realise that with any process using CMYK, black and white will always be a compromise unless you pay a lot (megabucks) of money for specialist duotone or tritone litho printing. I’ve found as a generalisation that all I usually have to do when soft proofing is to add a little bit of midtone lift.
