Nanographic Printing Technology from Benny Landa

[gordo]

This is the Landa mantra Gordo?

D

It seems appropriate because in the past three years since he announced the technology the basic issues about de-inking/recycling and the potential toxicity of the nano ink pigments (they appear to be small enough to pass through the skin and into the body) have not been addressed.

Let us name the companies that he has possibly fleeced with this premature and perhaps never to having technology. Komori is one...

Helene it is going on three years and still no response on deinking. Has a process been identified to deink nanotechnology?

I would bet that the sheets have not even been tested for deinking. Why would you tell your potential packaging customers that the printed products are not deinkable. IMOP I doubt if nanographic reproduction can every be deinked. One of the selling points is nanographic ink binds to almost all substrates.
Look at the heat and pressure used to transfer the ink from the belt to the substrate similar to a laminator running at a high speed. Another possible property is molecular adhesion. How do you overcome that to get the nanographic inks to release?

didn't have much to do so . . I went to Landa's website and searched for deinking . . .this is what I found - doesn't seem they are too concerned about deinking

They are too concerned about collecting everyone's dinero, that's about it.

They will avoid all matters related to the D-Ink-King.

D Ink King, pardon me

Well . . personally I prefer drinking to D-Ink-King myself - apparently Landa does also . . .

I have no idea how much of a problem deinking will be for Landa's nano inks but their process in not so similar to hot extrusion lamination. I have experience with extrusion coating and there of course, the pressures are much higher and the temperatures are very high due to molten plastics.

From what I remember, Landa was claiming that the transfer was without heat but it turned out there was some extra heat added just before the transfer point. Most adhesion is due to attraction at the molecular level. That is why with extrusion coating and other processes, substrates usually need flame treating or corona treating to ensure good adhesion. Sometimes primers.

I have heard the claim that they can print on any substrate but I am still curious about this. I would be surprised if they had very high adhesion levels. I could imaging failures in adhesion between the dried nano ink films and the substrate. Maybe if one shakes the printed sheet too much all the dots will fall off.

So the claim is that they can print on any substrate. As long as that substrate is not made of the same material as the blanket which is supposed to release all the dried nano ink films.

I think their revised-revised-revised schedule had them doing bata testing with customers now. I wonder how that is going.

Landa's got it wrong - in the tech business it's called "drinking the Kool-Aid" ** - not the beer or mulled wine. LOL

**This is what sales does when being trained on products.

Erik,

You figured it out and excellent point.

I have suggested this before about the nanography process and the 'absence of vehicle'. With the absence of a carrier of the color stuffs this fellow is promoting, there is absolutely no possibility of a plasticizing component that would give the printed film the needed film formation and flexibility to withstand the handling for the requirements of the mythical finished print product. (Sometimes I'll shock you Erik and words will be laid that will provoke your interest).

Look folks, without a vehicle / varnish deinking is a remote whim. It is the carrier that is 'LIFTED' from the substrate of a viable recycled deinked printing. The result is a washed like barren substrate which becomes a candidate for further life.

If Landa's promotion about the fusion of his super ink particles from a poly siphoned accordion has validity (it does not, by the way) than deinking is a secondary aberration of this totally absurd notion for a new printing process.

One last note on my previous post here; it is not the dinero Landa is after, it is the shekel. Also, God rest the 106 year old soul that died this week, in some circles known as Schindler from the listing.

Do not f... with Gutenberg and Senefelder. They had it correct centuries ago before this onslaught of digital, computer garb and pie in the sky Ponzi business.

Happy 4th of July to all the people from the grandest country of all and to all the people of the world and Print Planet.

Nanogrpahic is not patented. It has patent applications. The patent applications were in 2013 after DRUPA 2012. Reading the applications it is a polymetric resin and pigment in a water based solution. Uses a silicone based transfer belt. From what i have read it looks like pigmented plastic transferred to a substrate.

Here are the patent applications
http://www.google.com/patents/WO2015036960A1?cl=en
http://www.google.com/patents/WO2015036906A1?cl=en
http://www.google.com/patents/WO2013132418A2?cl=en
http://www.google.com/patents/WO2013132339A1?cl=en

It is somewhat based on a Lexmark patent
http://www.google.com/patents/US6709096

There is mention of molecular attractions in the patent applications.

Have fun reading.

After reading it is apparent there are innumerable variables to overcome and maintain to control the process. Wouldn't any type of substrate contamination eventually get on the silicone belt.
