Adjusting that floating kento, now that you ask!

Ah yes, a few of you asked how to adjust the floating kento.
With a "real" kento, little pieces of wood are inserted into the kento to adjust "out" and the kento is carved to adjust "in".
How to tell whether your kento needs to go "out" or "in" is something you have to figure out on your own. I think hard which way I need to adjust and when I finally decide, I do the exact opposite and I'm right about exactly half the time. I figure that's why God invented proof paper. But seriuosly, I have a much easier time adjusting the color image with respect to the key image since I started using this movable kento.

But back to the floating kento adjusting matter...
To adjust "out", that is, to move the block "pa ya" or "over there" or away from the kento, I simply insert little pieces of painter's tape into the kento. The tape is removable with no residue and can be added one layer (mil) at a time until the registration is as good as it's going to get--er, perfect, that is.

Them's the little pieces of tape, about the thickness of the kento-board; I stack them as thick as the registration is off...which it never is, of course, hardly...ever...

Next picture shows the little darlings stuck in place at the crucial corner and lower edge of the kento-board. This pushes the block and therefore the image AWAY from the kento.

And the block flush against the adjusting tape.

If the adjustment requires that the image or color block be moved TOWARD the kento, or "pa ca" or "over here" or "inwards", I just shave the block with a straight chisel, one millimeter at a time until I achieve registration.

Although this seems like a permanent non-reversible fix, if I shave too much...well, there's always more tape!!!
