Digital BW, The Print

what is the name for the "pattern" ,"weave", "grid texture" that you 
see when examining an inkjet print through a loupe ?

and, is it controllable - can it be made finer or less evident ?

(I have 'error diffusion' and 'finest detail' checked on & 'high 
speed' unchecked off,  if that makes any difference)

thanks for answering such a basic question
