My all-in-one scanner has an auto document feeder which allows me to quickly scan multiple pages, duplexed if needed, to a pdf. The problem is that when scanning to PDF, there is no light/dark slider adjustment like you have with the copy and print function. It copies and prints fine but when going to pdf, the grayscale scans are alway washed out and don't come close to 100% Black. I have Acrobat, Photoshop, Indesign, etc and was looking to a way to automate opening up each image from the pdf page and applying a level or curve adjustment in photoshop as this would be to time consuming on a large document. Could this be done with a script of some sort?
I could scan to tiffs and then batch correct the images and then place in InDesign with an import script and save the pdf but it seems there should be an easier way.
Batch correct the TIFF files in Photoshop and combine the TIFF files in Adobe Acrobat.
Yes, this option created the best quality scans from my printer.
You should use Acrobat to scan documents (File menu : Create : PDF from scanner).
Its powerful enhancement functions are stunning, not to mention compression.
I tried using Acrobat to scan as grayscale and it left a 4-5 percent dot in the background white. I was impressed with the features though as this was the first time I used for scans. I was able to control the level of compression with more control than scanning directly on the printer and having it save to pdf. The ocr option was a nice surprise.
Slightly better quality from scanning to tiffs and combining in Acrobat.
The fastest and easiest option for good quality would be to scan from the printer and batch correct the images in the PDF if I ever find a way.
