I've got a Genie III mug press (from Listawood: https://tinyurl.com/ydan4m5e) that was recommended to me by a friend, and that's used in conjunction with a Sawgrass SG400 and Virtuoso Print Manager (6.2.1777).
Manufacturer recommends (for 10oz Durham mugs) 165 idle, and 170 cook (for 45 seconds). Paper is TruPux Classic.
Using these setting I'm finding that my blacks are not very black, maybe about 90% black. I was advised to try increasing the cooking time in 5 second intervals, but gave up after the 6th wasted mug and +30 seconds! When my press is at 165 idle, if I put a mug into it, the temp drops (as expected) down to about 154 before going back up to the cook temperature.
Has anyone got a Genii III press, and if so, have you found a good setting for nice deep blacks? Any other advice for this newbie would be appreciated.
