Sure, that makes sense. It got me thinking though that a black pigment might have higher tinctorial strength and would have the added benefit of making the DCG matrices easy to identify.

Glad to know it was translucent, and yet still effective in its purpose.

I think carbon printers need to appreciate how easy this process would be to do, even with their existing glop. In fact, a matrix could be made in the typical transfer method onto a gelatin-free support. The gelatin would fog highlights as it would imbibe some dye.

Can't a carbon transfer more or less stick to any smooth surface? This would alleviate the need for a specially subbed product like the Estar Melinex.

Furthermore, it might result in sharper images; not having to expose through the base.

Just a thought...
