Sorry but no.
US count is Threads per LINEAR inch
Rest of the World count is Threads per LINEAR Centimeter

Not *exact* equivalence but closest one which is in ample use.

Each pair of crossings allows a single dot of ink to be applied,
Yes and no or it depends.

That is the basic/simplest way buy there are ways to get much finer results, independent from screen thread resolution.

Itīs done by applying a thick emulsion layer under the screen (thereīs different methods) , which serves only to *hold* emulsion, and engraving the actual artwork on that emulsion.

Not only you get very fine resolution, you avoid the saw edge effect caused by screen pattern.

Thank you for the clarification on the different ways of sizing the different screens.

By applying the emulsion under the screen, do you expose the image on backside, thus effectively making the screen just a mechanical means of holding the emulsion?
