Ok - if merging in DotSpy, drop the folder containing the tiffs you want to merge into DotSpy. Then go to the File menu: File/Save Selection Merged. It will ask you where you want to locate the merged tiff, then create a merged tiff with "merged" in the name. I also check the Prefs in DotSpy and pick the compression that I want for the tiff - usually I just save "as input file" (see attached screenshots).

In the very very rare instance that pitstop doesn't fix this and you really want to get the file right we will try saving as .ps and then redistilling to pdf then try pitstop again or try the convert colors palette in Acrobat ...but be careful...be very careful and select Convert colors to output intent, then choose the Dot gain 20% and check off preserve black. This will change all cmyk images and type to grayscale but if you have K text make sure it is all cmyk K and not grayscale K or it will get screened back....OUCH!

We have Pitstop 11 on all of our workstations now and it runs better than ever, with many more options for fixing the junk we get from customers. We also have Pitstop Server 11 and if you have a high volume of these crap pdfs it works real fast and is very reliable.
 
Or just fix with dotspy.... :laugh:

So, if I do the Dotspy method, since the 1-bit tiffs are already screened, won't it essentially give me a grayscalerosette pattern?

This did the trick!

I'm still working on getting some sample pages to post for everyone' experimentation. I keep forgetting my thumb drive.

Ummmmm.....yes.

Then that's not what I want to do - that would look weird. No matter, as mentioned above I resolved the issue using Acrobat's built-in preflight fixups.

Here's a page from the PDF for anyone who wants to see what's going on. I was using Acrobat 8.2.1 with Pitstop 7.51. I do have a newer version (Pitstop 10, update 3), but haven't been using it because I dislike Acrobat X's interface. I did not try to convert to gray with the newer one - just the older one.

Quote from: DCurry on September 07, 2012, 03:03:14 PM... in my mind, if you set up a good workflow to convert and/or merge crap like this, you just always use it and save yourself some headaches....

You would be correct sir.

Yeah, that is weird. Latest Pitstop doesn't touch it. Acrobat Preflight "Convert to Gray" works though.

It's got something to do with the text being a form. I haven't got it completely figured out yet.

Yeah, I noticed that. Running the Pitstop convert to grayscale action does nothing. If you close the PDF after running it it doesn't even asked you to save it so it's just completely ignoring Pitstop.

After I run convert colors and preserve blacks in Acrobat, I can then use Pitstop and Select Similar Objects to get the rest. I'm trying to figure out why Pitstop is having a problem. The form is in a clipping mask, even when I cut it out, it still will not treat the form as an object that converts. There has to be something preventing it...

Interesting enough, I CAN change it to a spot color through Pitstop.

It's got something to do with transparency in the form. If you select the form and tell it to "Remove transparency from the selection" it is automatically just in the black channel. Don't even have to convert to gray after that.

Really? I'll check it out. I didn't see any transparency on first look.
