Traveller (at least in the early days) was not printed in large numbers.
Which increased the per unit costs.
JTAS 1-10 were printed in runs of 2180 to 10,114, which is in the sweet spot for a small run jobbing printer.
As you yourself note, those small jobbing printers don't exist in the numbers they used to. The ones which are still in business tend to use different printing technologies too.
Your commentary about the cost of downtime and efficiencies of scale is technically correct but beside the point.
Correct, but besides the point? Sure, whatever.
A printer set up for shorter runs will produce a shorter run more cheaply because the downtime is cheaper on their equipment.
Those printers don't exist in the numbers they used to, remember? The short run and odd job shops which used to number 2 or 3 in mid-sized cities don't exist anymore. The ones that do remain are more likely to specialize in certain products for corporations. One of my clients used to print short runs of all types. Companies can compose and print all their internal reports and "credenza wear" themselves now so what had been a huge part of the short run shop's market no longer exists. In response, they shifted to printing "packaging" for fast food outlets like containers for sandwiches and french fries. Their equipment and skills shifted too so they can no longer print what they used to even if they wanted to.
You don't see many printers with that sort of kit now...
Which has been my point from the first. Technology hasn't just changed
how things are printed, it's changed
what stuff is printed too.
... print-on-demand tech (essentially high volume laser printers) has largely rendered that obsolete. However, it is more expensive per-unit than an offset press, so there will be some print volume where the improved quality and costs makes it cost-effective to do a print run.
Nice see you admit Adam Smith's hidden hand is still at work.
In 1977, how many short run printers were there in the Bloomington region for
GDW to contact for quotes? In 2018, how many short run printers are left in that region to contact? In 1977, how many companies would quote a price for printing the
LBBs? In 2018, how many companies could or would print them?
There are fewer printing companies around and they are more likely to be very specialized. The days where a printing contract for a daily newspaper or newspaper ad inserts could "carry" a shop and provide it with the capacity to print short runs is long gone.
The US lost over 100 newspapers in 2009 alone. Everyone one those papers kept local print shops afloat either directly or indirectly. In my region,
one printer now handles what regional daily papers still exist, the regional weeklies which used to be dailies, and some of the national dailies distributed locally. They're able to do so because they run 24/7 and are completely specialized for newsprint. They won't quote certain jobs because they can't print certain jobs. It's not even a matter of equipment as they don't have the necessary time.
