When converting from a pdf to a tiff some of the pages become blurred

Hello
We have been using your PDF to TIFF converter for many years, and it has worked fine for many conversions per day.
We are experiencing a certain problem for the third time.
When converting from a pdf to a tiff some of the pages become blurred.
here are the details...

PDF to Image Converter 2.1

XP PRO
(both trial and purchased versions)

When converting from PDF to TIFF, certain pages are "blurred" when converted.
It is usually a small percent of the pages, < 10%.
It is repeatable, the same pages will blur each time.
it is transferable, the problem follows the PDF from computer to computer.

OUR PREFERRED OPTIONS: 300dpi, group 4, multiple page
The problem happens for any combo of TIFF options, IF the resolution is greater than 198 dpi.
The pdf converts OK if the resolution is 198 or less.
The pdf converts blurred is the resolution is 199 or greater.

I have attached a one page pdf and a one page tiff that is blurred at 300 dpi and one tiff that is not blurred at 198 dpi.

It does not happen often, that we know of.
We have to have confidence in the conversions, and we are losing that.

Any idea how to prevent this from happening?

Thanks

  1. Similar problem. Using the HTML to PDF command line htmltools.exe on 9/6 produced a text based PDF, but as of 9/7 it was coming out as a somewhat blurry image PDF. I downloaded v2.6 and it did not fix the issue. Has this problem been resolved or does anyone know a workaround? I do not wish to convert to an image format in either case.

  2. What is the resolution of original images in your HTML file? if the resolution of original images is low, VeryPDF HTML to PDF Converter Command Line can’t increase image’s quality during HTML to PDF conversion.

    However, you may email to us your sample HTML file and image files to us at support@verypdf.com, after we received your sample files, we will check them and come back to you asap.
