Modern printing technologies made good duplication on the naked eye level (which will fool some collectors)-- however are substantially different than the original Pre-War processes. Most home computers use ink jet and laser printing which looks nothing like the old printing under a miscroscope.
It's not unlike automobiles. Model T-s are antiquated, out moded. Modern cars are less and less like Model T-s each year, not more and more. Simply check under the hood. SImilarly, laser printing illustrates that modern commercial printing has moved far away from T206 lithography and isn't going back. Printing with lasers and dry pigment would be science fiction in 1909.
And, as an example of one technique, laser printing is easily identified under the microscope.
