I noticed that the occasional mono pages which one of our local newspapers runs had pictures which were very muddy. It's a strong possibility that they are preparing all their pages in colour and just accepting that some of them may be run in black and white but a little time really should be taken to adjust for the lack of colour before it becomes almost a forgotten art.
It's a couple of years since a DTP-er I know was having trouble coping with instructions from a printer that detailed their pic specs as no less than 5% highlight dot, 80% max shadow, and midtones of 35 to 40%. The printer then added that this particular press might want the midtones down by another 10 or 15%.
That seems like a lot of old newspaper presses I know. Though, on second thoughts, they'd be hard pressed to hold a 5% highlight dot. My instructions on one paper were to drag both sliders in Photoshop in significantly, then drag the gamma slider across most of the way: no point in talking numbers, this was like engraving with a chainsaw -- provided you could hardly see anything on screen, there was a chance the final result would be fine.
The really amazing thing is that the final results were quite good.
This is the skill in working without color, and it is a good idea to ask a printer to show you what the original looks like for any black-and-white photos that look good (and maybe to give you the file) so you can see what you have to produce. Once you know what an original should look like on your screen, it is less necessary to work by the numbers. And some of those movements in the sliders within Photoshop can be far more than you would try without seeing an example.
The same principles apply to photocopying. Color is more forgiving than mono, but it is still worth learning some of the old skills. They can produce better color pics too.
And why do some pages have to run in black and white? That is because it does not matter to a large web press whether it is printing one color or many. It is the total number of plates which matter. A press can have the paper run from the reel (web) in many different ways so if fewer color plates are needed then more pages can be printed in the one run. So, some late ads can be accomodated without a second run and collating the two sections if some of the existing pages can be printed in one color instead of four.
