The surface is noticeably nonuniform and the black's thickness is noticeably deeper than top... Dye-sub process doesn't make perfectly saturated color, I suppose.

Today's failure
Dye keycap's sides!

Black background
I tried to dye the sides of keycaps by some ways. Coating is not good, I suppose. Coated surface is completely different from dyed surface.
My result:
I've abandoned. Dye-sub is the only way. Black background will cost astonishingly high...

Better contact
I bought a new vacuum cleaner:)
I made a silicone sheet jig. The silicone sheet sometimes wimples while heating because it gets longer by heat. This jig gives a little tension which avoids wimpling.
I got perfectly saturated consistent black! For money savings, most of these caps are already printed test chart. Blank keycaps are expensive in my budget.
Printed on blank keycaps:
Perfectly saturated consistent black. I've gained some confidence with my method.
But I've found printing misalignment. I feel my keycap mount is not stable enough. In principle, plaster is highly stable. Aging is required? I went wrong while alignment? Anyhow, I have a plan to make new design keycap mount.

Contact is important
Today I've found the contact of dye-sub film and material is important for consistent result.
The inconsistency of black thickness is came from the inconsistency of the contact. I need better contact. My vacuum cleaner may be not enough...

Compensation of ink bleed
Now I'm trying to print black background and compensate ink bleed.
The image what I want to make:
What I printed to dye-sub transfer film:
What I've got:
A bit stronger compensation is required, but image sharpness will be lost more.

How to make a keycap mount: Part 3
Prepare test chart.
Microscope image:
Print the test chart and compensate each keycap's misalignment.
Microscope image:
Hmm, ink bleeds about 2 px (600 dpi). Some compensation is required, but this is a bit hard problem.

How to make a keycap mount: Part 2
Cast plaster.
Peel off OHP sheet.
Separate mask and base carefully.
Clean up mask's film side by file.
Drill air holes.
Calibrate printing image roughly.
