Were always trying to come up with inventive ways to get a tight registration on multi color jobs. I find it quite annoying to be constantly adjusting my gauge pins, moving the plate, taking apart the chase, adjusting furniture etc, etc, (you all know the drill). The closest way I found was using transparencies which I wrote about in an earlier post Multicolor Registration, but we have something in the works that might be alot easier when using photopolymer plates.
We are using something called a translation stage which consist of a base and a platform and the platform moves in extremely small and precise increments, I’m talking microns. What we came up with is to mount a piece of .25 inch aluminum to the platform of a translation stage, thus making it “type high” when a sticky back photopolymer plate is added. You can actually take the whole translation stage and lock that up in your chase. When you need to make fine adjustments you need to turn the dial on the translation stage and you can move the platform right to left without ever adjusting your gauge pins.
When we finalize the details to this, I will be sure to share it with everyone. In the meantime, if you have no idea what a translation stage is or what I’m talking about, here is a picture for your reference. For those who have an idea of what I’m talking about, I would love to hear your ideas on this. If anyone is interested in this please contact us at firstname.lastname@example.org.
