Need a Carlson/IntelleCAD Guru . . . (*.ctb question)

I use a *.ctb file to make my drawings look the way I want them to . . . 

(I should start by saying my CAD background is marginal; I know enough to make my 1 dimensional Certificates of Survey look good)

Every once in a while I go to print a drawing I just prepared, and it appears that it doesn't use the CTB file to control the printer. . .  dealing with one right now.

I use line colors to control weight and width of the lines on the printed drawing; and its acting like it's using the monochrome ctb instead of mine . . . 

I imported another drawing into this one while I was preparing it, and there were some blocks.  When I noticed the problem, I deleted the blocks, then purged and audited the drawing to no avail.

Does anyone have a suggestion how to solve this?
