too many unknowns....
too many unknowns....
sighhhhh, you got too many unknown, thus there're 2 possibilities:
#1 if you do not go through a software RIP to send data to the printer, you have to print via the printer's driver; and you can do two things :#1 choose the paper type that yield best visual result, for e.g. semigloss photo paper, semimatt photo paper, etc., and beware of those settings that you can choose in EPSON's printer driver #2 you can create an inkjet icc profile via 3rd party software, so that you can color manage using icc profile (this process can either be purchase commercially or find a consultant to help you... not just for this but also future tech support)
#2 if you have a RIP, then you need to do (i) ink limiting linearisation (ii) icc profiling; it's a complicated process beyond average users ability to handle, you need the RIP dealer or an independent consultancy to do that.
#3 your choice of paper on the front panel should be either clear film or any vinyl related name; but make sure your vinyl as proper coating to accept pigment ink to be on it.
