VanSon still produces a few old style letterpress inks, though
offset-inks like their panthone-series in tubes behave too
nicely on letterpress. As I experienced.
Offset-inks contain a lot more pigment, than old-style inks for letterpress
some decades ago.
Composition-rolls, that's aq bit oldfashioned and old-style.
If you are willing to use a few extra sets of rolls, because the behaviour
of composition in winter and summer... When the humidity of the air and the
overall temperature changes, the diameter of these rolls will alter too.
So in the past, most printers had extra sets of rolls. And not only because
the need for clean rolls doing colour-printing. (Printing yellow with rolls
used for black... is quite a cleaning-job.)
So using composition...
you will need extra work, adjusting the pressure of the rolls,
when ever the season changes. Or the installation of an air-conditioning.
By the way, keep your composition-rolls away from rodents.
Those rolls are perfect food for mice and rats:
sugar, glycerine & gelatine from bone-glue...
A friend of mine can tell you more about this.
Rubber-rolls do the same job, and presently the rubber can be produced
in many grades. Soft or hard or in between, you can get it all.
The price of composition compared with rubber-coated rolls, that's no reason
for using composition either.
