Is this what commercial printing has been downgraded to... (...)
Images will mostly likely be under 100dpi, I doubt anyone is forced
ot use a 25 lpi screen, so this is sub standard.
Where did you get this idea from? If I put a 300 dpi image into it, I
get a 300 dpi image out. 600 in, 600 out.

That is what commercial printing has been downgraded to - no real
technical knowledge, not even experience, just prejudige, opinions and
misinformation...

Whatever the internal vector format is - WMF most likely - Acrobat
doesn't seem to have a problem with it.

When the file is converted into PDF using a printer driver, what Acrobat
Distiller sees is PostScript and after the conversion the format is of
course PDF.


I guess this is an open-ended discussion but...
1. of course there's a chance that whoever created the powerpoint files,
used 300dpi. About as much of chance as being hit by an asteroid.
Don't play russian roulette with powerpoint. It's most likely 100dpi or less.

2. Vectors in powerpoint, I would not trust personally. Possibly with a good printer that will make sure output res, overprints, traps are all decent, and paths aren't jaggy... o.k. This would require some work I'm guessing here, cause I'd never put the pressman through such misery. But if you guys want it... go right ahead :) Ask yourself this: Would you accept powerpoint files for a 200 page magazine, expect a few hiccups perhaps :)

3. PDF isn't perfect. cmon. Saying powerpoint vectors are good to go cause they look decent with an on screen PDF. Did you sep the job? Is distiller set at the proper settings or is it just set at generic default that would acccept any piece of trash :) Is X1-A on? Did you preflight that PDF... ETC..
I've seen PDF's sebd to press that we're pure trash when tested but they looked great on-screen.

4. I guess being pragmatic is necessary. Printing files that aren't up to par is going to happen. Agreeing to print the sub-standerd jobs is o.k, . Everyone is printing JPG's, I mean even when the client gives you a JPG and u save to CMYK tif and sent it to the printer...it's still crap. But the problem is the control is shifted to the client because the printer has no choice but to accept these files. The client believes JPG is god since the web. Powerpoint, word document, they've come to loves these files and push them on the printers. And that's the way it is. We made a choice and that choice isn't about money, it's about convenience. It's convenient to just take the files, time is money and why invest the time to educate the client or even lose the job. I'll agree that sometimes you gotta just bend over and take it... But don't diss a guy that calls it like it is. crap in ...crap out You start with 100dpi you end with a shitty halftone screen. This industry is at a low level of quality output, client's fault... conveniently.
