Repeated many times, but the difference is, they didn't do anything other than omit the coloring due to the nature of the printing.
Here's something to actually discuss, then.
We did not just take the color files and print in b/w - we actually made substantial adjustments to that book - twice
. The tables, especially Chapter 4, are the easiest example - if you don't have the PDF, you won't know that the tables are still color in that file, while they're in alternating "accountant style" lines. Likewise, all images and tables were color adjusted for b/w to make sure they actually printed in a greyscale range. The darkness of "ghosted" images, that some complained make a number of pages in first printing, were reduced considerably to make teh book more readable. Artifacts along the outside edge were reduced and elminated to make a cleaner book.
Granted, we did not re-contract all the art or template - it would have cost us far more than we had to spend - but we did go out of our way to make the book as b/w friendly as we could in the process. The changes are subtle, but the work was (agonizingly) done over last spring and summer by Pat. I totally understand how they could be missed, but the work was put in.
It comes around and when he mentions the second path, one has to wonder if he's realized what happened.
We're all adults here. Give him the benefit of the doubt and move on. Pressing the point is going to continue to throw this thread off track.
