I have the manual for this equipment and have scanned it the best i can. Compressing the pages to 300kB files is no problem when using JPEG. As soon as i try to save the pages as PNG the file size explodes to 1MB and more. PNG compression setting in IrFanview is set to 9. I tried many other features to reduce size: converting to grayscale, resize etc. How do i upload the manual ?

I also have the tube chart, i haven't even started to scan the document out of frustration...

Dear Patrick,

if the manual has no high resolution photos, I use to scan it as greyscale 256-level images. The next step is to enhance someway the image to the right contrast and resize it to a convenient size: 1200 wide for 2000 high is usually enough for easy reading. Then I decrease the color depth to 8, using the Floyd-Steinberg dithering option of IrfanView and save the resulting image using the best compression level, 9.

Hope that this way can help you.

Emilio

Thank you for the info, Emilio.

I tried again with your tips in mind and this time it worked.

Now for scanning the tube chart...

Greetings,

Hi Patrick, hi Emilio,

you may get even better results without dithering.

Best regards,

I still have a whole lot of documents to scan. I'll try all features to get a maximum result.

Best regards,

Patrick
