I received 76 four-color pdfs containing unrecongnized text and photographs. The pdfs were scanned in at 72 dpi. Each file was about 50-150K. I combined them into one 76-page doc that wound up being 7.5MB. I was asked to decrease the file size because "it's going on the web." I was able to reduce the file size to 4MB which kept the document legible. It didn't look great, but you could read. I was asked to take the file size down further. At 3 MB, the images pixelated beyond recognition, and the text blurred out in several spots.
Here are the steps I tried to reduce the file sizes:
1) Optimizing then reducing the file size via Acrobat Pro: "Create reduced file size pdf"
2) Manually selecting the image output resolution and optimizing the file in AAP
3) Printing the file as a PDF and manually selecting the image output resolution in the print properties window via AAP
4) Small PDF software
5) Turning the file into a gray scale version
6) Cropping
7) Multiple combinations thereof
I asked a few designers and they all agreed that a 76-page file created from scanned, four-color docs full of tiny type would look blurry at 3MB. Does that sound right? Does anyone know anything I can do to create a lower file size PDF? Is there somethinge else I can do becaised what I tried in the list above? The final pdf was put on a website, and when you clicked on the link, the pdf opened in another window. Is there a better way to handle a big pdf on a website?
This also happened with a doc made up of 24 scannd 8.5 x 11" pages, all b/w type, + a red watermark. I couldn't get the file lower than 1.8MB. Does that sound right? When we ran OCR on it, the file size jumped to 10MB. Can I get these file sizes lower? I work with someone who thyinks we should be able to get all teh files to about 1MB. That seems very low to me. Does that sound right?
Any advice anyone has would be greatly appreciated.
THANKS!
