About screened vs ink jet printing, many of the reissues are no longer screened the way they used to be. Hermes has always been quiet about that, to point of letting everyone be blissfully thinking the printing process has not changed. I doubt an SA would know for certain how a design is made.
An obvious difference is the addition of colors in the backgrounds, all that remix stuff, color blocks. That hides the fact that the design itself printed quite differently - fewer screens/colors.
One possibility: new issues have less shades of gold (for ex) in the gold hardware. The result is more comic book / graphic looking than the original printing due to lack of color nuances.
Another possibility is the use of a finesse style - pen & ink line drawing designs which are testament to the fewer screen trend. The tattoo series , the bandanna, this seasons legendes de l arbre are examples, C est la Fete CS scarf.
Ink jet printing is yet another possibility. I think all (most) of the 70s, maxi twillies etc are done that way. Maybe not the twill 90s. Could not say about the 140s. My silk 140s certainly look to have been inkjet printed.
How can you tell? An experienced eye can tell the difference. The easiest way is to put two scarves (new & old) alongside one another and compare some detailed sections. Are they identical ? Does the new designs look blurry ? less crisp ? Those are signs of ink jet printing. Count the colors - fewer means elimination of screens.
