I will comment, but if you want to get into a very extensive discussion of the carbon process I would suggest posting to the carbon transfer forum

But in short, too much moisture in the tissue at the time of exposure can cause irregular lines that look like crossword puzzles, especially with vacuum exposure units. Diagonal lines are also caused by not soaking the tissue long enough in the mating bath, not waiting long enough in hot water to develop, not enough sugar in the pigmented glop. Sometimes this problem can be very hard to diagnose for a specific work flow since since these can vary so much.
