The viscosity of soft plastisol inks will result in an increased amount of ink expansion or dot gain.  When printing a detailed graphic with soft plastisol inks one must compensate by adding a “choke”.  We typically add a 0.25 – 0.5pt stroke (centered to path/selection).  In the following example this corrective measure was not taken, the customer rejected the order, we had to eat and reprint.  Ouch!  I do however get some sense of satisfaction in knowing that at least someone else is agonizing over the small details in the same way I do.
