So we are clear - You contend that the WHLFCOLB.PDF is a true color scan of a paper copy of a document that was originally created with a printed form with typewritten and hand written text added.
You also contend that you can duplicate the characteristics of the file WHLFCOLB.PDF such as layering, color abberations (absent), grouping of content in layers by logical text, bit characteristics of layers, green and black handwritten text, pixel size differences, exact duplicate letters, different size letters, masking characteristics (layer monckton findings) and white halo effect.
Wow - if I read you right, you are amazing. Please show us!
The best ones working for the CIA can do the same thing.
Trying to read the augers in modern scanning systems is as fruitless a pursuit as it can be.
