My name is Syd and I work for Epson America, Inc.
The printer will accept transparencies but they cannot be completely clear. The media would need to have some type of coat so the sensors are able to pick up the media. Make sure to run a few tests to ensure the media is compatible with the printer.
The printer is not a postscript printer out of the box. You can print postscript files to the printer with the use of RIP software. There are a variety of RIP’s that will support the printer. The main thing is to select a RIP which may perform the functions you desire.
Hope that helps,
I take it that Ulanocut is the same thing as "masking film" (Rubylith, etc.)... if so, depending on what type of ink you're using, and how intricate the openings, you can use things like masking tapes and other tapes, various kinds of non-permanent glues/etc., or even paper.
Perhaps you should ask this in a screen printing group though, and/or be more specific about what you're wanting to use it for:
HTH, and good luck,
