lined paper

I differentiate books as journals being lined and sketchbooks being unlined. Using this terminology I think there are many sketchbooks that wish they were journals, but lineage was not available. Lined book blocks and paper are available, but that smart handmade paper that you really like is rarely going to be lined. For this reason I have been lining my own paper. I have the option to draw, print, or emboss the lines, and I can decide the color, gauge, and spacing of the lines.

Any printing method works. I have used etching, aquatint, and lithography. I haven't used screen printing or wood/lino cut. One of my favorite results was from a frame wrapped with mono filament fishing line. The fishing line leaves the printed line as well as a light score in the paper.

When drawing lines I set up a template with marks for line spacing. I place a rule at the appropriate mark and follow the straight edge very closely without touching the rule. This is my personal technique for making a very straight line that still has a looser hand drawn feel. I've also projected the lines with a digital projector and traced the lines.
Whether drawing or printing I set up my template or printing plate so that the length of the paper is at least two signatures long. I make the lines on both sides of the paper then tear the sheet at signature length. Picture a toilet paper roll with lines running the length of the sheet and then tear off signatures as required. That is an exaggerated picture. Most of my prints and drawings tear down to give me two signatures. The matchbook size I get four to six signatures.

Sometimes when printing I'll get four signatures from one plate by drawing my plate so that the top and bottom of the plate are the tops of two signatures. The center line of the plate is the bottoms of the signatures. After printing both sides of the sheet, tear once length wise to get two double length signature sheets then tear those down to single signature length. Confusing description I'm sure. Using the image below. Picture it as two plates each large enough to make two signatures. The top plate is right side up and the bottom plate has the signature tops at the bottom. But instead of two separate plates make it one plate to print one large sheet that is then torn down to four pieces.
Hmm, not sure if that's any better. Maybe there is still something usable here.

printing hardware, improvised

I had a conversation with Meredeth of Yatsu fame from the etsy bookbinding group. The conversation lead to talk about printing and producing lines in a homemade, handmade, self-help fashion. I've spent the last five years around presses and have been making my own lined paper, so maybe now is the time for me to expand on the topic a wee bit.
I'll start with the press. When I hear people lamenting over not having a press, one of my first comments is--Make one. Bookbinding is already about taking the long route to getting a book or journal, so why not dig the hole deeper. Books are about multiples whether it is duplication within the contents of a book or duplication of information between books. The press is also about duplication. So don't let not having a press be an obstacle. I'm mostly speaking to the people who have a print related idea but think they are stuck since they don't have a press.

I won't go too much into using a wooden spoon. I haven't had much luck with the technique (mostly because of my application), but do remember that it is an option.

The mechanics of the press is basically the idea that anything that will exert pressure can be used for printing to some degree of success. The photo in my article about adjusting photographs is a picture of several wood presses that work well for letterpress and block-type printing. Notice the resemblence to clamps?

To cover the actual construction and printing techniques would involve writing a book which is not my objective today. This is a primer. The internet is loaded with homemade printing press plans. All seem to be variations of similar ideas. One of the older how-to-build-an-improvised-press books is a Popular Mechanics book published in the 1960's (I think). I can picture where it was shelved in the universitiy's technical library, but I can't find it in the catalogue. Anyway, the technical library usually has something on improvised presses if the school has some sort of printmaking program. The key to remember is that for etching and litho printing some sort of roller or scraper bar needs to be incorporated into the press to concentrate the necessary pressure to transfer an image. Materials are easily found. Plywood, and standard hardware. The roller can be salvaged or found at tinkerer suppliers like American Science and Surplus (this store is a gem in and of itself).

When I began my quest to build a litho press, some printers told me it was impossible to build something out of wood that would create the required pressure. I remembered seeing one of Gutenberg's original presses, and it was made from wood. Sennefelder, the inventer of lithography, made a suitcase-sized, portable press made from wood. I was looking for a certain look when I built my press, so I used solid maple. If function is the only objective, plywood should work nicely--it's lighter weight too.

Pictured is my press and the resulting print. Everything is wood except for the leather on the scraper bar and the plexiglas for the tympan. The litho stone is local limestone from a landscaping supplier.
A much simpler press can be built much more easily if function is the only concern. I took the extra trouble with this press to prove that it could be done.

prototype

This series of images should be self explanatory if you begin with the idea of a box for storing supplies and progress to a cradle for everything a cradle is used for. The cradle/box is a prototype, so it is short on embellishments like handles, latches, pulls, and interior dividers. It is one of a kind and the precursor to a series. The construction is masonite and glue with strategically located slots to allow it to do what it does. Dimensions are approximately 3.75 x 11.75 x 9.5 inches closed, and when opened the cradle handles standard 8.5 x 11 sheets folded in half.
Note that the bottom of the cradle is nearly flush with the bottom of the box. The needle I use when punching signatures has enough clearance. If someone uses a longer needle or awl and needs more clearance, a folded piece of corrugated board or a couple pieces of heavy felt as a liner should do the trick. It works for me.
I've had this idea in the back of my head for some time. The holiday promotions at Bookbinding Etsy Street Team (BEST) gave me the push to roll this thing out. The box will be discounted for my promotion. Go to BEST blog to see the daily promotions offered by other team members between now and Christmas. My promo date is Sunday, December 21. This box will be greatly reduced on that day if it's not sold before then. It's already listed in my shop.

mitered corners






When I learned how to make mitered corners we learned a really involved and contorted way to do it. The corners were perfect, but it was very process intensive. I won't try to describe it. It finally occurred to me that there was a much easier way to do it with identical results. If anything the results are better considering how much less the book has to be handled. Less handling, less mess, fewer accidents. I since ran across this method in print but can't remember where. The sequence of photos are fairly clear. The only critical consideration is to use davey board that is the same thickness as what's being cover. The angle doesn't even have to be a perfect 45 degree angle, and the edges will still meet straight and flush.

Using mitered corners is not a necessity. Folded corners leave more cloth in the corners for wearability. The mitered corner is smoother and less bulky when that matters. The mitered corner is more durable than it may look, because the glue has a chance to impregnate the ends of the cloth fibers locking the edges together, and the end pages have a smooth, flush surface to adhere.

sanded edges

Sanding the sides of a book block can be done with as little as a sanding block. For more precision clamping the book block between two boards help to keep the sanding block square and level. The following is how I do it.

The tools (from top to bottom): wood blocks, micro plane, shims, and sanding block. The wood blocks I use are scraps from a canvas stretcher. The micro plane for removing larger amounts of book. Shims for evenly raising wood blocks. Sanding block for sanding edges.


I have several sets of shims of various thicknesses depending on how much paper needs to be removed.


Blocks clamped then inverted in vise of work bench.


Before and after.

center finding ruler

I love rulers, but this one holds a special place in my warm little heart. About one half day of heavy use, and my brain was noticeably mushier. It doesn't take much to figure out how to use it. An example if it isn't readily apparent. Say I have two dots four inches apart and want to find the half way point between them. Place the ruler next to the dots so that one dot is left of the zero and the other dot is to the right. Using a bit of intuition move the ruler in the direction that balances the measurements on either side of the zero. In this example the left dot will be on the left 2" line, and the right dot will be on the right 2" line. The zero is the center point! Plus without doing any math the ruler shows that the center is two inches from either dot!! The ruler really earns its keep when it's 0200 in the morning, and the dots are 4 13/73" apart.

This is another one of my tools from the print studio. I used it mostly when setting the registration marks on paper before printing multiple runs. Paper didn't have to be the exact same size, but I always had a perfect center. Now it is stored with the book tools.

photo adjustment

For the longest time I was frustrated with images that came out discolored. Especially the white ones. That crispy snow scene or drawing on white paper always ended up gray. This is the one click solution for those who can't or don't want to become involved in more complicated photo manipulation gymnastics.

First, to understand what causes the problem. The camera can only make two adjustments--how long the shutter is open and how wide the aperture opens. Of all the metering and measuring of color and brightness of a particular scene, in the end the camera can only accept one setting for shutter speed and one setting for aperture. It ends up being a game of assumptions and averages. The typical decent photo is assumed to have so much light and dark, which averages a certain amount of gray. To properly replicate this "classic" gray there is one setting for shutter and aperture. The computer in the camera is programmed to calculate the proper setting from its sensor readings of a scene. The game goes awry when a scene is not typical in color or light. In the case of much white, the camera only knows to strive for an average gray, which pushes the white scene into grayness. Light sources cause the same problem. Camera sensors read natural light as cool and light bulb light as warm, but the problem is that the camera doesn't know when it is encountering which kind of light. This is the reason there is daylight and tungsten (light bulb) type films, and digital cameras have settings for inside and outside shooting.

Try to use the camera's adjustments first and use photo editing software for clean up. Most photo programs have an auto adjustment feature, and this feature can solve the majority of problems with one or two clicks. In photoshop I think there is an auto levels, auto color, and auto contrast. In paintshop pro it is called one-step photo fix under the adjustment drop down menu. The above images are a before/after example of one click editing. Image on the top is rather warm because of incandescent lighting. The lower image has been edited and is a closer match to the wood's natural color and canvas backdrop. Now try these simple adjustments on your snow scenes, drawings on white, and objects sitting in front of light colored backdrops.

In a real hurry? Try using the camera's built in flash and see if you can live with the front-on lighting. Colors are usually accurate, because the camera is calibrated to the flash, so it knows what to expect.
