Nifty Registration jig


I made up a handy dandy registration device for my reduction print.  I took a class last year with Chuck Miley where we used easy cut block material and used a sort of mat out of foamboard which we dropped our block/s into.  The foamboard was the same size as the paper, if I remember correctly.  So I adapted that idea for this flexible block I'm printing with from McClains.  I cut a piece  binder board/davey board in a thickness that was thinner than my block.   I made sure the outer measurements were bigger than my paper.  I traced the block onto the davey board and carefully cut out the block shape so that the resulting frame would fit snugly around my block.  Then I laminated some graph paper and did the same measuring and cutting.  Then I glued the two together with a glue stick.  This enabled me to figure out exactly where the paper would lie.  I cut two strips of the binder board and glued them along the paper line forming an L.  For extra measure I glued a triangle of binder board over the corner  but I probably didn't need to do that.  It might have been better to be able to see the corner to make sure I had fitted the paper into place each time.  The laminated surface was easy to keep clean.  I still have one more color to print on 60 some prints but so far the fit is still snug around my block.  There might be a slight up and down wiggle room but each time I place frame around the block and snug it tight against the "L" corner.   


I've had registration on my mind lately, as I'm trying to work out an easy reliable method of registration for my Poco Proof Press.  So far I've made a tympan and frisket, (awkward in several ways) and  I've attempted to register on the cylinder (seems to be some slipping which might be my tympan cover not being tight enough).  What seems intuitive to me would be a sort of snug mat around the form which could lie on top of the furniture and onto which I could  lay the paper.   I have a matcutter and could maybe print onto a piece of matboard and then cut out the printed areas?Maybe I could have a board that is type high that locks along the edge and this matboard could be attached with tape and hinge?  Still thinking...   There's gotta be a better way!

New arrival--a proof press!!






Well, I couldn't let that workbench stay  empty, could I?  I spotted this proof press on ebay within driving distance (thank you, husband) and I put in a bid and  fortunately won.  Then I panicked--was this really going to print type and wood/linoleum blocks? So I used the time before pickup day to do research and quell my fears.  I focused on registration since I think that's the weak point for a simple proof press like this as opposed to some of the Vandercook proof presses.

 The sellers were very nice people--someone in the family had taught printing in a school and had a shop in the basement.  I quickly checked the press and saw I was correct that it will print type-high stuff so that was a major relief!  It is a LinoScribe proof press.  Apparently there are some LinoScribes that  print rubber type that's only made by the company but other LinoScribes are for proofing and sign printing. 

 Before even cleaning up the press I eagerly got out an assortment of cuts and type and linoleum blocks and tried it out.  Oh my gosh--it worked great!  I love the dial on the side that changes the height of the roller.  I discovered that it has a nifty mechanism to hold the paper in place that consists of a row of "fingers" which are operated by a handle held tight by a spring.  The roller mechanism opens the "fingers" by depressing the handle when it is in the farthest position to the left.   After putting the paper in place you can roll the carriage just a bit and the "fingers" close tight.    

I can see I will need to keep notes on how high the roller setting should be for different kinds of printing material.    The grid that was in the press bed was filthy and damaged so I removed the bar that holds that in place which is at the opposite end of the press from the "fingers".  I replaced it with graph paper covered by a layer of acetate.  I'm thinking I can write on the acetate maybe. Or maybe I'll want to put a grid specific to each printing job under the acetate/mylar.  

  I can see there will be a period of experimentation before I figure out the best way to deal with registration.  I've seen plans online for a frisket and tympan device but since I already have a way to secure the paper that doesn't seem like the way to go for my situation.   Maybe some strong rectangular magnets would be good to make sure my block stays where I want it when I'm in a hurry and don't want to bother with locking up the traditional way?   Always lookin' for easy street!!!   Also, magnets would hold the graph paper/acetate down at the corners.  I can't see a way to secure them at the "finger" end of the press bed.

I would love any input from experienced users of presses like this--there's just not much on the internet that I can find.
