QTR-Quadtone RIP

I recently formulated an eight shade high optical density Piezography ink and a transmissive version of the Piezography profiler. I am mostly using Pictorico films.

I am making large scale positives for Photogravure for a client. Photogravure uses sensitized carbon tissue which is adhered to copper and requires a very specific density range. The profiler automates curve creation and produces either full density film or preferred density film that is linearized.

For silver and platinum I can create film with density over 2.7 quite easily. Gravure density range is actually quite narrow.

The new ink does not scratch off and the film can be used more than once.

I have no plans to turn this into a Piezography product - but do plan to offer Piezography film and negative services to those who require very high fidelity films and/or very specific density ranges.
