Ilford galerie creative emulsion coating bar?

[J 3]

I was looking at a photo stores offering and saw these offered in 20 and 40 micron versions. They are marketed for people wanting to make ink jet paper but $200 USD for a 17" one seems really steep just to end in an inkjet print.

Does anyone know if these are general purpose precision coating rods (I can't see the price otherwise) ? Would one destroy them trying to coat baryta with them (clay in a gelatin base) or trying to coat a silver gelatin emulsion or carbon tissue with one?

Very interesting. I haven't heard of this product before; thanks for sharing. I don't really have anything to add except that it looks like they come in two sizes: 40 microns and 80 microns. I would say this is a bit on the thin side for coating silver gelatin emulsion, generally you want something in the range of 5 - 10 thousands of an inch (~130 - 250 microns). The 80 micron one might be acceptable.

What does your "Ilford Galerie" refer to?

Baryta coating is not "clay in gelatin" but instead a suspension of Baryte in gelatin.
(abrasive implications though would be even higher for Baryte)

Baryta is typically not coated with such bar.

I use a coating rod from RDS Specialties in Webster NY
the rod is a 3/8 inch inch x 16 inches
they are referred to as a Meyer rod
I use it to coat POP emulsion onto fixed out baryta paper

Thanks. That was my mistake. I thought barium sulphate was one of the natural clays (though it need to be synthesized to be bright enough) but it's not. It's a good visual metaphors regardless for what dragging baryta might be like though. Article I saw doing it used a glass tube with some spacers on the end so I'll do that for any baryta.

Thanks so much. The pre-fab RD Specialties rods are much more reasonably priced (quarter of the price Of Ilford's) and come in any thickness you could want.

They Will also make larger coating roads but you have to request a quote on those.

After seeing the RD Specialties offering It have to say Ilford's offering is pointlessly overpriced. I was just trying to reconcile why they would sell such an expensive setup solely for the purpose of creating inkjet paper (not my thing but what do I know - Inkjet prints line the walls of museums and galleries these days).

Thanks so much for giving the silver gelatin emulsion thickness ranges. I've got a project to coat with Foma liquid emulsion for a bromoil print and that narrows things down. Im thinking aim for the thicker end of the range but need to do a bit more research.

Ilford (the japanese one) are offering a coating bar. It it is not listed at their site, but is hinted at the descriptive text in the manual (actually they offer two different bars).
