TIFF to JPEG with Automator

I am on Snow Leopard, but I could not find an Automator discussion for Snow Leopard.

I am doing a large scanning project and using Automator to convert TIFF to JPG. I find that it generally works well, but inevitably, many of the resulting JPEGs have horizontal bars of static. Sometimes I can "Rework" the bad files back through Automator and it will correct the problem. Other times, the horizontal bars of static persist, and I have to manually go into PREVIEW app and convert from Tiff to Jpeg there. I notice that when I do it this way, I get options for quality level of the conversion. Default is 80% and I can bump it up to 100% and a larger file size.

I will have batches of from 5 to 100 slides that I process in this way. The average batch size is about 25.

My initial Automator workflow was
1) Get Selected Finder Items
2) Copy Finder Items (to a new folder, so I don't wipe out the TIFF files)
3) Change Type of Images (to type: JPEG)

This workflow will copy all the TIFFs to a new folder, then it opens them ALL in Preview, and converts them all rapid fire to JPEG. I thought this might be a problem so I put a loop in the workflow. So now my workflow looks like this:

1) Get Selected Finder Items
2) Dispense Items Incrementally
3) Copy Finder Items (to a new folder, so I don't wipe out the TIFF files)
3) Change Type of Images (to type: JPEG)
4) Loop

This new workflow gets a higher percentage done correctly, but there are still several images that have the horizontal bars, requiring manual rework.

Does anyone have any suggestions?

For the record, my entire workflow is the following. I know I could automate more of it, but cannot when I have to do the manual rework.
1) scan slides on Epson scanner
2) Use A Better Finder Rename to rename files.
3) Run Automator workflow to convert TIFF to JPEG
4) Run A Better Finder Attributes to change file dates of jpegs
5) Import into iPhoto, name the Events, set Faces, set Places, do Edits including crop, color correction, etc.

Thanks for any ideas.

Do you have a copy of Photoshop or Photoshop Elements? I prefer to do my image batching with that, because it has more options and just does a better job.
If you do:
1. open Photoshop and go to the Acions palette.
2. Open one of your tiff files.
3. Click on the new action button at the bottom of the palette (it looks like a page with the corner turned down)
4. When the dialog comes up, name your action and press record.
5. Go to File > Save As, and save your file with the settings you need, then press stop.
6. From here, you have 2 options for automation. You can run the action as a batch, or you can create a droplet, and just drop files on the icon to do the action.
7. To run a batch action, go to File > Automate > Batch. In the dialog you will specify the action, a folder to pull images from, and a folder to save the new images to. Be sure to check the box that says "Override Action "Save As" Commands".
8. To create a droplet, you go to File > Automate > Create Droplet. In this dialog you will select your action, a location to save the droplet, and where you want your files saved to. Again, you will need to check "Override Action "Save As" Commands".

Droplets are really handy if you are going to be running the same action over and over, but you can't always specify a new location, so I usually end up creating a folder just for gathering those files, and then move them after the I run the action.

Thanks,
I do not have Photoshop, but I do have Adobe Lightroom Beta. I may give that a shot.

It is odd, but I have found that I will always get at least five "bad" conversions with the static banding. If my batch size is 10, I get about five bad ones. However, if my batch size is 100, I still get about five bad ones. It seems that on the long runs, it does better, which is counterintuitive.

you may want to insert a pause after the conversion on your loop. perhaps that will make a difference? another thing you may try is to get imagemagick and use the convert command in that to convert the images. Imagemagick is available via fink and macports. also, some 3rd party programs install it. I use MacTex and it installed imagemagick for me so I didn't have to deal with either fink or macports.
