Hi Shaun,
so could someone please explain why I have to set my paper in my printer driver to Museum etching.
When using a printer profile, the driver must be set exactly the same as when the profile was made: paper type, no colour adjustment or equivalent.
Setting the paper type is important because different papers respond to the ink in different ways and the driver controls the amount of ink depending on the type. I believe gloss paper requires less ink than say matt and there would be differences within the types.
