It's really a case of "needs must". I don't use the MRC compression facility in PDF Pro unless I really have to, e.g. for attachments to this forum. For my own purposes I scan to .png (or .jpeg for pictures with no or minimal text), then tidy up the individual documents before creating the uncompressed .pdf. If needs be, the individual documents can be size-reduced before .pdf creation. E.g., often text-only .png scans are just fine with conversion to black-and-white, which reduces their size immesnsely.


Cheers,

To get pdf file size down to forum limits, when scanning items that do not contain continuous tone images, I select the "text/line art"option on my scanner menu. To adjust the size of continuous tone images I use the Microsoft photoed program that came with my windows 98 pc but runs happily on XP. File size can be adjusted in 1% increments. Futher adjustment in novapdf is possible via the dpi resolution setting.

I'm considering 'biting the bullet' and buying a professional program that can do the conversion more efficiently whilst retaining the overall quality ... so JulesOmega I'll be delighted to compare notes when I meet up with you re. the Tek transformer that you've so kindly (and patiently!) kept for me, ahead of my next visit northwards

Best wishes

Hello Guy, I've been trying to complete the scan of a manual that Ed Dinning kindly lent me, in time to take it back for the Golborne swapmeet on Saturday. I finished tonight, having scanned everything at 150dpi. All pages were then carefully edited to clean them up, sharpen and adjust brightness/contrast. All were saved as JPGs at 58% quality except for fine schematics which were saved at 68%. Crucially, none were re-sized.

Then I PDF'd them with Image To PDF or XPS and after a couple of goes got a perfect PDF document. I was so pleased, I made a donation to the developer!

Hope to meet up soon, or I could email you a smaller PDF of just one of the schematics from that manual.

I hope "Saturday" is simply a typo, as you may have a long time to wait for the doors to open if you turn up then, the swapmeet being on Sunday!
