Been doing more tests on Lyve now. Now trying to use a pure MBK base media type for a custom media in MCT - Highest Density Art is the only one available (besides Special 6-10). I chose 'Standard' ink usage (as the build in 'Canvas' also has).
After 24 hours of drying / outgassing, I have measured the target print. Being curious of the apparent very delicate/sensitive surface which easily gets somewhat shiny if touched (especially on darker tones), I tried rubbing my finger across some patches, and was surprised to see ink spreading out to neighbour fields - even without damp finger or varnish. Trying the same on other mat media, I don't notice such tendency of smearing (only that mat surfaces generally easily get marks/shininess if touched, to varying degree). Attaching images of this dry-test - no varnish applied this time.
Haven't tried to varnish this print yet, and might skip it now, as smearing already when dry doesn't leave much hope of bettering compared to last attempts.
As I'm getting used to with the Pro-1000, it's difficult to understand the use of MBK and PBK, as plenty of PBK is still being reported in use by accounting manager for what is reported as pure MBK media types. If that reported PBK is being put on paper despite a pure MBK media choice, or it's dumped outside paper for various reasons but still reported in accounting, I don't know.
But back to Lyve. I'm starting to run out of ideas on how to make the media work, and would love some input on making it work. I had of course hoped not to spend a lot of media, ink, thought and time on this, but I'm still interesting and believe it can work out in the end. Can I have been unlucky and gotten a bad batch with poor coating? Batch number is T6B26-C.
