I have a laminated table-top I am painting. I started with two coats of BIN primer, and followed with two coats of latex enamel (I would have used oil-based enamel, but the store didn't carry it in the tint base I needed). Now I want to apply clear lacquer to get a glossy durable surface. Should the paint cure for a certain amount of time before I apply the lacquer?
(Yes I can read, yes, I've read the directions on the can, but I know paint can be slightly tacky for *days* after a paint job. When is it safe to lacquer?)

Actually, you are better off with a latex enamel in this case. A high acrylic content would be good, but you are stuck with whatever you put on at this point. Oil based enamels are actually softer than modern latexes.
Latex paint will dry to the touch rather quickly and should loose the tackiness within a day or so, depending upon how thick your coats are and heat and humidity. Even after this, chemical reactions will continue to take place for quite some time within the paint film. It can take quite some time for the paint to fully cure. Again depending upon conditions, the process can take up to 4 weeks.
If you lacquer over paint that is not fully cured, you may have a couple of problems. First, the curing process may be stopped so the paint will not reach full hardness. Also, salts may develop on the surface of the paint under the lacquer. If this happens, you may notice small star shaped discolorations in the paint. If you must use lacquer, wait a nice long time, sand with a very very fine paper and wipe down with mineral spirits to give the lacquer a better surface to grip to.
As Mr. Wolf mentioned, a clear waterborne poly would be a better choice. It will allow the paint to continue to cure after it is applied and is much easier to work with. Two or three thin coats instead of one thick coat. Best to let the paint cure about a week for the poly.

Hi, usually in 24 hrs. But make sure your lacquer will go onto a waterbased paint. Hope it turns out for you,Bye.

With all due respect and without a long answer WHY lacquer?
With latex why wouldn't you consider a POLY based Clear coat?
