Dear Dan, Here's _my_ take on your questions... Watercolor in tubes _can_ be used to good effect. The only drawback to using prepared watercolor is that it is considerably more costly than powdered pigments, but also presents less health hazard (don't breathe that powder!) and it's more convenient. A number of the more experienced moku-hanga printers on Baren use pigment dispersions -- costlier than powder but cheaper than prepared watercolor -- the powder has already been ground and dispersed into water or water/alcohol -- that way there's no danger from dust, but the dispersions generally don't have any binder, so people add gum arabic or gum arabic and glycerine (some also add honey) -- search our archives and the encyclopedia and you'll learn exactly what several others do. Supply sources can be found at http://www.barenforum.org/encyclopedia/entries/007_04/007_04_frame.html The 'glue' (actually, we usually use nishiki=rice paste) is usually used as a 'vehicle' for the pigment -- the paste is usually mixed with water to the consistency of heavy cream and is much more viscous than water (also a 'vehicle' for the pigment). 'Usually' a little pigment is dabbed onto a dab of paste on the dampened block and all are mixed together using a brush just prior to dropping the paper and pulling a print. There are a LOT of factors which influence how the color goes into the paper, but generally speaking, as the amount of paste decreases, the pigment particles tend to 'flock' together more and print with a decidedly grainy texture called goma or goma-zuri -- rice grains. As the amount of paste increases (and the pigment particles are dispersed evenly into a thicker and more viscous layer of paste), the graininess disappears (maybe the pigment particles are prevented from migrating together by the more viscous paste) and with enough paste and a thick enough film, 'brush strokes' appear. Another way to describe this is that the addition of paste helps you achieve the application of an even tone in a single pass, but increases the tendency for your brush to leave its signature as the viscous paste tends to 'remember' the ridges and valleys left as the brush combs through it and the thicker parts contain more pigment and therefore print darker. Gee it's hard to articulate this stuff -- I feel like I'm failing miserably! Different pigments have different characteristics, so experience really will have to guide you. Get your paper and blocks damp and try this: print several sheets in a pale color using only water as your 'vehicle' and also try over-printing a few sheets with the same water-only mix. Then print several sheets in the same depth of color mixed into a lot of paste on the block and I think you'll see the difference right away. Personally, when I want to print a REALLY intense color, I tend to reduce the amount of paste and when I want to print a really SMOOTH color, I tend to increase the amount of paste. With any luck, you'll get better answers from other printers, too and you may be able to intuit the 'truth' from all our different ideas... :-) - -- Mike PS -- are you the "Dan Kitchen" pictured at http://dailytitan.fullerton.edu/issues/spring_02/05_17/news/couplecombines.html ??

I'm having trouble figuring out what size wood pieces to order from my man down the hill for Exchange 15. I have to figure in kento marks and I'm just about losing it trying to figure exactly what I need. The paper will be 5 x 15, of course, but the wood is what? Let's say I want a one inch border all around because I like big margins around the image. So how far in from the wood does the kento start? My boards would have to be what size? If, say, the kento starts a half inch in from the bottom of the wood and I need a one inch margin on the paper before the image starts, and my image would be, say, 3 x 13, then would my boards be 5 1/2 inches by 15 1/2? Also can the top edge of the board be the top edge of the image? You don't have to start carving the top edge of your image a little from the top of the board, do you? The reason I ask is I notice on the hanga piece I did at Boot Camp, the top edge wasn't my top edge of the image, but it seemed for some reason the border of the image was carved a little lower on the board. Why did I do that? I don't do that when I carve for oil-based ink prints. Also is there a way to put images on the board WITHOUT doing the hanshita pastedown. I'm also not a good consistent paster downer of things. It would be typical of me to paste one or two of them crookedly, thereby messing up the registration. The way I do it with oil based is to carve a keyblock and print it and use the still wet (the beauty of oil is it stays moist a long time giving you lots of playtime) image to transfer onto other boards, and it's very easy. What would happen if I print the keyblock in oil based ink onto the other boards like when I do oil based prints, then carve them. But from then on I use hanga methods? Would that work?Lots I'm also dreading carving the kento marks. I did them crookedly at Boot Camp because I am a crooked carver. I think that's why I have not gotten more involved with hanga; the mechanics that have to be perfect. Using a registration board and taping down dry paper is much easier for people like me and it's why I do oil based ink prints. Also, I like that the color I mix is the color I get and it doesn't change when dry. So, now that I said all that, I still am giving hanga another try and that's why I signed up. I just want to get over my nervousness around the process. People who are steady as a rock in their carving and measuring and pasting skills are going to do fine. People like me -- I just don't know.

Although I have read David Bulls page on Hanga and watched Mike Lyons tape, I am still befuddled. I have the image ready but the spirit is still not willing!!!! I am afraid I will go back to oil based blocks after this turmoil is over. And thanks to all of you who answered my question about re using the block; to David Stones, and Sharon. The block I am carving will really look much different than the original block when I incorporate the two. Also, want to mix the woodblock with monotype and etching. That is what makes printmaking so adventurous! Print on. Oh, here comes the Hanga back to Haunt me.

I don't as much carve as I chisel my kento marks. A regular carpenter's straight blade chisel with a sharp edge should do the trick...1/2--1" blade width. Important thing is to draw your kento marks in correct alignment with your drawing....else the paper will be slightly off, crooked....I did that once....only off by a bit but enough so that my edges were off and my print crooked.. Try practicing on a spare piece of wood first. Just lineup the flat edge of your chisel with the inside part of the kento line and give it a good whack with a mallet to drive the chisel in 1-2 millimeters...then proceed to the opposite side of the kento line that makes the 90 degree angle and repeat the process. If your kento is large or your chisel is small...you can "walk" your chisel along the previosly cut line by starting your next cut with 1/2 of the chisel blade engaging into the previously cut. Once the lines are cut...I use the chisel to pare out the wood directly in front of the kento triangle......and then around the edges of the kento lines. hope that gives you some ideas...Julio ------------------------------ From: Date: Thu, 19 Dec 2002 09:15:59 -0800 Subject: [Baren 20167] Re: MDF print and Ink question Dan...

Mike cost $12 and is so worth it. Everyone in my class used it. Make your wood 6"wide and 16" long. Let the paper hang over on the two edges opposite the kento if you need to have a wider border. This will give you plenty of room to do a kento and have your image 5"x15" or a little smaller and still have a large border. If you get your copies pasted down crookedly, don't worry. If you think you cannot cut a straight edge along the side that is a bit crooked, get a metal straight edge, lay it on the line and gently carve a line next to it with an exacto knife, just keep going over and over it until you get it deep enough. If you do it gently there will be no problem with the rule moving. Go for it girl!!!!

I usually carve dry, print dry, often on dry paper. In the oily world, I carve my "key" block (in quotes because it really isn't a key block but more of a "guide" block"). Then I ink and place that block against a fixed registration jig, print that block onto a fixed sheet of non-shrinkable paper, switch the block and print paper on wood, and so on until my design is transferred to every block. The "kentos" (in quotes because they are not really carved on the block but on a jig against which the block is placed. Now for hanga method, tradition dictates that I introduce uncontrollable variables into my registration. VARIABLE 1: The wood expands and contracts with humidity VARIABLE 2: Each block is slightly different therefore it is likely to expand and contract differently VARIABLE 3: Each time I carve the same lines I am likely to not be exact, speaking in micrometers VARIABLES COMBINED: I'm supposed to carve the kentos exactly the same on pieces of wood that are supposed to contract exactly the same...but when the wood expands and contracts EACH kento is going to be off by a few micros...but differently, HUH???? Never mind the pasting of the hanshita thing (more humidity, more paper/block expanding contracting), which I am avoiding altogether by using the laser transfer method from identical laser printouts. My question: What would happen in moku-hanga if I use my usual jig, which would eliminate variable 3 right off the bat and control at least one portion of the shrinkage/expansion thing; and further, keep at least the kento marks exactly in the same place throughout printing? It has always seemed suicidal to me (although worthy of immense admiration) to have that many variables and still come up with perfect registration. With the jig method, the expansion and contraction of each individual block would be easily corrected by sanding the block or adding masking tape to the block so that it would be closer or farther from the kentos, respectively. Somebody slap me...I'm almost sure I'm headed for disaster, but logically so.

Plywood blocks will have VERY little expansion, and if any, it will be consistent from block to block. Too bad the Baren Mall doesn't yet carry Matsumura-san's hardwood plywood blocks. The hanshita step should not introduce any variables, because they are printed on dry paper and glued on dry wood. If you are going to use laser prints, check carefully that they are all the same size before you use them, I found out (after carving, of course) that the same machine can spit out copies one after another that are slightly different dimensions.

Hi Jack, About plywood and expansion,...ahm, well what you say is true and not true. Expansion in plywood depends on the types of wood used for the ply's versus the surface, the glue type, and the overall size. Obviously, the bigger the block, the more noticeable is the expansion. With glues, some are more rigid than others so they will hamper any expansion -- stiff glue is one factor in plywood seperation. (Glue stays, wood moves, plywood unplies!) And finally, if the inner ply's are different from the surface wood, then 'fun' things happen. For example, take a plywood with an oak exterior on one side and a poplar core, and when it gets wet, it either warps or the oak cracks. I've seen birch do the same thing, even with a birch core. As for the consistency of expansion, since each wood and piece is unique, with unique grain, they expansion is not consistent -- most people do not get out their calipers and measure from one piece to another! You can also get some interesting thickness expansion from piece to piece, thanks to grain lines. One other fun factor in this wood expansion discussion is that Maria (and I) live in the desert. The humidity here is VERY low, so when she moistens wood, any effects from the water will be magnified since the wood is extremely dry. When I lived in Iowa, woodblocks printed with water-based inks didn't hardly expand, warp, or do anything. In the desert, the same block expands, warps, etc. enough for me to notice it. (Hmm, wonder if that was enough to REALLY scare Maria?! Hahaha!) Linda ------------------------------ End of Baren Digest V21 #2065 *****************************
