Anoprint, Ano-tone?? 

.

Looking for ANY info on Anoprint or Ano-tone. Not sure if thats the technical term, but thats what we used to call it 20-30 years ago. The process is one in which a screenprinted image (dye, ink??) is somehow penetrated into the alum. and then anodized and seald. I know this process exists, but not sur of the exact process or materials.

We've experamented with our 'normal' inks, usually screened over anodize, but when we try to screen then anodize our ink falls off in the anodize tank. Like I said, we used to do this process 20 years ago so I know its not new to the industry, however, I cannot find ANY info as far as process or materials.

Is this highly Proprietary information? If not, someone please help. We have full screening and metal finishing capability.

Any help would be greatly appreciated.

Contact Clariant Corp. (formerly Sandoz) they put out several inks for screen printing anodized aluminum. And I believe they are called "Aluprint"

"Anoprint Anodize Dyes

Product Description

Anoprints are anodizing dyes which are silk screened into unsealed anodized aluminum surfaces to create graphic logos and other color effects. Anoprints are solvent dyes as opposed to water base anodize dyes, dispersed in a solvent system with thickening agents to create a high viscosity. After silk screening, the parts may be dyed and sealed without affecting the printed logo.

Intended Use

For creating graphic logos which are silk screened and sealed into the pores of anodized aluminum.

Creating multiple color on the same aluminum part.

Serves as a resist to dyeing after printing.

As an anodize touch up for rack marks, bare spots ..."
