Re: P800 ink limit

Thanks for the warm welcome.

That is really strange. My densitometer (http://www.fag.ch/products/pdf/FAG%20C5%20GB.pdf) gives correct readings (± 0.01D) for all reference check specimens (zeroed on white, then reading of C, Y, M, K using appropriate filtration). When comparing the appearance of the black specimen (1.63D) to the darkest patches of the 21 step (> 2.50D) that I printed (see first post, on Epson Archival Matte) - the latter look much, much darker (velvety, pitch black) - thus underpinning the meter's readings (?!).

I am aware that inks on matte papers normally don't lead to those values and it is not my intention to insist on the correctness of the readings.

Is there a quick way without requiring additional hardware to check if the densitometer is in working order aside from checking with the references?

Could it be an operator issue? I don't use a color filtration but "K" setting.

I am as new to the Epson and QTR as I am to using a reflective light densitometer. Do you know of any good tutorials, 101s, literature, etc.? I am not looking for a step-by-step guide primarily but for something that explains all the parameters, mechanisms, etc.
