INFRARED:
A PUZZLING IMAGE OF HIDDEN WRITING?
These images were a complete surprise. I had been working on two methods of developing any hidden information on the Verse 70 page, first was to use bleach to remove thin layers of ink and then once that was done I used the IR technique discussed in previous posts. I pointed out then that the kit isn't complete, in fact, I am waiting for some IR filters which should drastically improve the output.
I have no idea where this apparent writing came from and I am not making any claims at this stage. It only shows up under Infrared, (No filter), the first image is actually how it appears when first photographed with IR, it is negative.
This next image has been inverted so it is the positive version of the image above:
The writing, if that's what it is, starts at the edge of the cover to the left and stretches through the hat image of the lady with the fez and then further across to the right-hand edge.
I have looked to see if there's any cross-contamination from another document but I have no other docs that were handwritten which this appears to be. There are multiple lines that look to be in pairs but they are not equidistant. I will repeat the process and see what happens next time around and post on that tomorrow.
Incidentally, the bright writing at the top of the pages is from the last line of Verse 70.
There may be a simple explanation but right now it remains something of a mystery!
MYSTERY SOLVED
Well, in reality, I knew what it was but wanted to use this as a lead into the issues of the steps that you go through when you're examining 'questioned documents'. It is not as straight forward as it may seem. The process involves a range of equipment, a range of settings and occasionally software. In earlier days there was more reliance on software but as euipment, notably cameras and lighting needs advanced there has been less and less reliance on software tools. In fact almost zero.
So the solution to the mysetry is that the markings shown on this image commonly occur when you change ink cartridges in inkjet printers. Why inkjet printers? I will address that and other equipment used in a separate post. The problem is fixed by running the head cleaning routine that you will find in your printers software. Whilst you are doing that, you may as well run the other diagnostic tools in the printer software.
