Nitro adds a pattern on top of a 300 dpi jpg image

Hi Nitro,

I'm using: Nitro Pro / Serial Nr  23460x-xxxxxx-xxxxxx

I converted a newspaper clip (raster image scanned @ 300 DPI) into a pdf file.

The result looks pretty bad, Nitro added a pattern on top of the image. (see Attachment)

Is there a way, a setting that prevents this?

thank you for your advice

Hi Moderator,

Is my post out there visible for the group? I'm not sure, so far I didn't get any response.


Thank you

Hello @Ha Witche,

Thank you for reaching out to us through our Community Forums and my apologies for the delayed response.

In order for me to further assist you with your concern, could you please provide the following?:
-Did you use Nitro Pro 11 to scan your document and what is your workflow?
-If you scan the same document using Adobe, are you getting better result?
-Have you tried scanning with Print Quality as per image below?


Thank you very much in advance and I am looking forward to hearing back from you.

Hi AllainU,

It worked!

The setting "Print Quality" was the solution to the problem.

I had 300 dpi scans in form of jpg's, and choose "High Quality" when I put it together to a single pdf file,  assessing "High" better then "Print".

Thank you for your help.
