Dye Ano Printing

This process has become increasingly popular with manufacturers over the last 40 years or so and the applications are well known to many of our countries flagship companies.

The durability which is explained in full on our product page shows that it is almost impossible to damage.
The image once it has been encapsulated below the surface of the host material.

The first step is to open the pores of the aluminium sheet in an electrolyte using a 10% sulphuric solution.
This produces 1000’s of transparent vertical tubes at a controlled depth of 20 microns.

The next stage is to dry the sheet in a controlled environment and prepare it for printing.

What you have actually created with this process is corundum, a crystalline of aluminium oxide (Al203) in the mineral form it is known as Sapphire or Ruby which is 9 on the mohs scale of hardness.
Diamond is 10 so you can see it is a very durable surface treatment.

We deposit light fast dyes into these now open pores and after drying we seal the surface hydro thermally creating a ceramic surface, which is durable and rendering it scratch and solvent resistant like no other substance.
