How to disable image processing/sharpening when converting BMP/TIFF to lossless PDF quality

Hi,

I'm converting BMP and TIFF images to PDF. My setting are lossless conversion, but the resulting PDF pages/images are different from the original images in terms of sharpness. Some preprocessing/sharpening is done when I convert BMP to PDF. I want that my PDF has the exact same images that I select, and not some preprocessed variants of those. I configured the conversion to be lossless, but preprocessing even so is done.

Please help.

How do I completely disable image proprocessing when I convert BMP/TIFF to PDF?

Thank you!

How have you verified that it has changed? Be sure to view the TIFF/BMP at 100% scale and the PDF at a scale that matches the size exactly, as different apps will downsample differently.

P.S.

Other viewers use dot for dot pixel mapping (I think), but Adobe does not.

So I need to disable dot for dot in irfanview or whatever or enable it in Adobe. In irfanview, or Windows image viewer I did not found such option.

Is such thing in Adobe?

Although it would be nice an Adobe option that sets automatically the resolution based on the PDF image resolution, so I don't need to set it manually.

Thank you for your support!

No, that's not the purpose of Acrobat. It indeed does not make sense to convert images into PDF if it is just to have them in PDF.

No, I don't want to just make a PDF from some images. It is a scanned document that I want to OCR scan finally.
