The author's preface:

After years of the born of the keyless printing technology, the all its halftones color strength (saturation) values detectors haven’t been standardized and utilized yet!
This research article (Pressure personalized zonal divided doctor blades- A developmental suggestion for the keyless newspaper printing technology) tries to codify a too innovative developing suggestion, which is applicable on the newspaper lithoffset keyless web machines as a second halftone strengthens values detector (beside the thermal personalization of the anilox roll).
This innovated suggestion based on dividing the doctor blade (ink wiping knife) into sections under variable pressure loads. These one width profile doctor blade sections are similar to the thermal variable strips on the anilox (ink metering) roll. The final target of this research is: more color add-value of the printed newspapers.
I think this research article should be put with the other valuable scientific researches deal with the keyless lithoffset technology and with the newspaper printing improvement and add-values as a wider concept.
I invite the web keyless newspaper lithoffset machine manufacturing leaders, the newspaper printers & all the interested in newspaper adding value sciences & technologies to carefully read this research article.

The researcher:
Dr.Ahmed Mahmoud Yosri Ahmed.
