No coating has been necessary but I'm not sure how to get a more continuous low-contrast transparency. If there is a piezography inkset which improves on the K3 inks to do this I would be interested in purchasing them for use in a 4800 with refillable cart's.

>I have used both Piezography K6/K7 through QTR and OEM Epson K3 with Epson's ABW set to finest detail etc. to make transparencies for photoetching and though I almost choke to say it, the K3 with the ABW set to neutral, finest detail etc. makes a very usable positive - in both cases in order to achieve a full black aquatint the darkest parts of the image must be reduced to 80-85% output using curves in Photoshop (just slide the far right down - dont bend) - no need to relinearize - I've used films from Inkpress, and oddly enough Staples "house brand" corporate express with good results - the CE film has a rough coating on the print side which actually enhances the aquatint effect- the % at which you set your blacks will depend a lot on what works for your exposure set up
> If you want to experiment with a commercially available Piezography ink set that will stick to film, the current Selenium MPS Black and Selenium K7 shades 4 and 5 are replacements to the Epson K3 inks. But you still need to find a way to create some sort of 3 ink curve for QTR and a way to control the contrast you are seeking...
