It may not be an issue for many manufacturers until they find themselves in the position Efke was in ... where needed maintainence costs for their plant over shadowed their output and profit potential.
Fotokemika is a special case and not comparable to the other film manufacturers:
Their coating machine is completetly different to all others in the industry: It's a single layer dip coater (all other are using multi-layer slide hoppers). A technology which was already outdated 50 years ago. This machine was built for the former Adox factory, and when this factory closed, the machine was moved to Croatia.
And since then they have not invested in it.
They even fired the last remaining QC engineer.
One reason why this factory so often produced crap. Big variations from batch to batch, emulsion holes, scratches, lousy roll film converting......I've so often had problems with their products.
They simply could not compete anymore against the much much superior quality of Kodak, Fuji, Ilford, Agfa-Gevaert, Foma.
And now investing money in their coating machine would not make much sense, because with this completely outdated principle they cannot reach the quality level of their competitors.
Surely all the film coating lines of most manufacturers out there have been around for years and may be pretty creaky by now. I've just checked in my Yellow Pages for 'film manufacturing equipment repairers' and can't seem to find any!

There are several coating machine manufacturers. Coating is used in other industries, too.
And by the way inkjet papers are also coated, and the machines used are the same used for film and photo paper coating.
Therefore there will be no problem on the machinery side.
