AZ42 Ultra Clear Overlay

AZ42 Ultra Clear Overlay

Alternative to Agfa C-42

Known as the supplier of the impossible-to-get items.

The scanning world relies on a very clear grade of polyester (Mylar) from Agfa,and a few "not so clear" alternatives. Supply of all of these products has been limited, and we have heard that the quality of what is available is of great concern to users.

Look no further, we have your solution … AND A PRICE ADVANTAGE!


Without getting into a lot of chemistry, polyester is a man-made material derived from a base material of ethylene glycol (better known as automobile anti-freeze). It has amazing properties and can be made into everything from clothing to clear, plastic film. Almost all of this "clear, plastic film" finds its way into applications other than scanning overlay sheets. In these other uses, the polyester is coated with something to make it function properly for its desired end use. These coatings render it unclear for scanning purposes. Even the polyester that is used as a base for photographic film is coated and has an optical impedance that we read as the base density on our densitometers.


With the supply and quality complaints from the marketplace, our good friends at Aztek realized that they had a major problem. As manufacturers of scanners, they needed the material to support their product. They decided to design a polyester scanner overlay sheet from square one. As a result, this new product is optically clearer than anything else, past or present, in the marketplace.

AZ42 is the only polyester overlay sheet on the market that is specifically designed and formulated for scanning on either drum or flatbed units. Heat-sealed, plastic shrink wrapped in reusable, flap-seal boxes.

The Application

AZ-42 can be used on both Drum Scanners as well Flat Bed Scanners combined with KAMI mounting fluid to increase optical resolution Unlike other Mylar overlay materials AZ-42 is optically clear and invisible to the scanner. This equates to more efficient work flow and cleaner scans from the beginning. RC.

Useful Hints

AZ-42 can also be used for reflective scanning without mounting fluid which will allow you to mount a print on a surface without applying tape to your original print. This can be very useful especially in cases where the original material is delicate.
