I'm trying to print out several images on one sheet with a true black background.
I've made a preset and all is working well, except I cannot get true blacks from my printer. They are coming out a deep navy blue.
I've tried a range of different profiles, media settings and rendering. All to no avail, the background frustratingly remains the same once the ink has dried. When wet, it appears far blacker. Very little black ink is being used, so I presume that the profiles are trying to make black with cyan and magenta which are going down rapidly. I've tried changing black ink cartridges (I'm on compatible inks). I've also downloaded a wide range of ICC profiles trying to get something to work. I'm not getting any bronzing.
This is for an event whereby the client has stipulated A4 glossy with black background and I have to print them there and then on location. I'm using an EPSON SX235W as my LF 7800 won't travel easily(!) and my Dye-sub only goes to 9x6 in. A 12x8 dye-sub is £1800, so a non-starter.
in summary, changing media type, photo quality, ICC profile and rendering intent are having no effect on changing the background colour to true black.
Any ideas what else I can try please? I've spent several hours on this so far and am at a loss. Furthermore I have to print them tomorrow!!
