Image collection for coating team access. Click images twice(OSX) for a high res closeup

10u ABV over blue. Rough, but perfectly sealed.

20+u of Image over gloss. Remains smooth, but too thick so it will crack

2+u of release layer over Image. Look at how smooth the top is. This thickness did not interfere with image color or density formation.

2u Release layer. Like a ruler. 

This week's Three Layer Mix over blue. Hills and bumps like a cheap hotel room ceiling. Dmax inside the valleys is perfect. Almost no Image remains on the tops of the hills. 
The white spots are just the hilltops and the polluted Dmins are reagent puddles.

1966 T47 uncoated area. Image is 1-2u thick and the colloids can be seen too. Brown area is hydrogen sulfide affected lead acetate nucleant degradation where I missed with the print coater.

GreyBack from Polaroid. Looks familiar.

November Update - a setback and some progress

It was bound to happen: The tight schedule we set out for ourselves over the Summer went well, and luck was with us as we developed an all-new receiver sheet.  The work done by Ted and Jake, in particular, yielded at least two good performing formulas. Last month I reported that we had a November 6th date to coat one of them, but the formulas didn't cooperate, and now have to be reformulated to a new schedule.

The outcome of this could be a delay in the first receiver sheet that we expected in November. That would set the schedule back by about a month, and we are attempting to fix that.

Good progress on the pod paper. A new potential vendor has been found and the race is on to get it in sooner than the old supply runs out.

The clips are performing well.

A snag in the paper supply: The paper supplier has a minimum of 5000 pounds, which we agreed to. Now they expect the paper run to occur in January. Obviously, we can't wait that long. If you know of 9 to 10 mil, black, 60# rolls of dust free paper somewhere (NOT craft paper or construction paper) we can buy it.  The cost of the material is $3.10 per pound so a 5000 pound roll is $15,500 - before converting, slitting, and transportation. A roll that big cannot be picked up by hand. We are looking for an alternate supply.  This paper is the material used for the tongue. Once we have the paper, a vendor applies the various tapes, makes laser cuts and other things, and does them beautifully.

The economy is improving which is good and not so good for small R&D companies that need the big companies to pay attention to them. Such is the case here with a few items. I will give an update on all these in two weeks.
