The post by Neomoses regarding color depth, and the issue brought up about current density and acid ratio got me to wondering something. That is, how is it determined what the ratio should be? It seems that there must be an optimum acid concentration for a given current density. Obviously, it is somewhat forgiving.
But for example, if one were to use 8 amps per square foot as their standard, shouldn?t the ratio be somewhere in between the LCD standard of 5% acid and 15% which is commonly used at commercial current densities? I guess I should just give it a try since I seem to have many variables under control, but I was wondering what the results would be if I used 8 or even 12 amps per square foot at the LCD acid mix. In other words, I am wondering at what point does the ratio need to be higher, and what will the effects be if it isn't withing range or is borderline?
