Decal paper to label keycaps

Hi
I took advantage of the keyboard I made with keycaps from 7bit grab box thread to try water-slide decal paper.

Not as good as doubleshot but can help for custom layout.

I used transparent decal paper for inkjet printer.

After printing the layout and a varnish spray coating
Image
each keycap mark is cutted apart
Image
After a few seconds in water, the thin plastic sheet is applied on the keycap. A warnish coating is then added with a brush.

On this first attempt :
* some bubbles are visible, mainly on darker keycaps. Use of "micro set" and "micro sol" could have been interesting.
* edges of some labels come loose a little;
* with a particular angle of view, edges are visibles;
* a few mistakes (F3) and alignment not perfect;
* this method is only valid to make labels darker than the keycaps.

Next time will try dry tansfer decals.

Looks better then expected :D.
Please share the dry one aswell. Have you tested on top of caps? How resistant are these to typing?

Front part is smooth so decals stick well. The top part of those keycaps is granular so it could be even worse than conceivable.

On smooth top keycaps with a good varnish coating I imagine it could last a bit, but parsonally I would not try.

For dry decals, it depends on round 5. If sorting is efficient, I would not launch a new project to wait for it.

jeff, if you happen to have some callipers, can you please measure the dimensions of the base of the blue keycaps. If it is from SP, it should be 18.16 x 18.16 mm.

vvp : base looks like a cushion. Middle to middle is 18.17x18.17 mm and edge to edge is 18.35x18.35 mm.

Ach, right, That is DSA. That should have been 18.415×18.415 mm based on SP data. Near enough.
18.16x18.16 mm (I mentioned before) is for DCS.
Thanks.
