Creating puzzles
Post some basic instructions. What makes a puzzle "logically solve able" or "not solve able" when creating a puzzle.

Ben is correct. Logically solvable means that it uses deductive reasoning - that means you never have to make a guess. A bad nonogram app is one that you can't solve without guessing.

"Logically solvable" means the puzzle can be solved strictly through deduction and without the need to guess. In other words, given the numeric clues for a puzzle, only one unique solution exists.
For example, a puzzle can not contain an isolated 2X2 square with opposite corners filled in since the clues (1 1 and 1 1) can be satisfied in two different ways (either the top-left and bottom-right are filled or the top-right and bottom-left are filled).
