Chemigram to photogravure (for printmakers)

figure 1

(Franco Marinai sends a guest post)

I do my chemigrams on 8x10" high contrast orthochromatic film, not on photo paper, since I will port them to photogravures when I'm finished. I use undiluted Golden varnish, bleach, Dektol, fixer, warm and cold water.  The transparency of the film allows me to reproduce the chemigram on a copper plate and ultimately ink it, wipe it, and print it on a high-pressure press as an intaglio print, thereby giving me the three dimensionality and subtle tactility of an etching.  But I will do this following the more demanding photogravure process, which is best known for the elegance of its continuous tone reproduction and its exceptionally intense blacks.  This will ensure fidelity to the mesmerizing graphic qualities of the chemigrams.

Fig. 1 shows the final rinse of an 8x10" chemigram on orthochromatic film.  I use hard water, rich in magnesium and calcium cations, from the well in the square outside my studio in Serrazzano, Italy.  Serrazzano is a small medieval village on a hilltop 25 miles south-west of Volterra.

Here (fig. 2) the transparencies have been cut and masked in preparation for the gelatin exposure in the vacuum frame.  The chemigram of the one on the left was started with immersion in bleach, while the one on the right started with Dektol.

After the gelatin has been exposed, transferred to the copper plate, and developed in warm water, the plate is covered with a fine layer of rosin (aquatint) and readied for etching (fig. 3).

figure 4

The plates have been etched for twenty minutes in ferric chloride (fig. 4) and cut to the size of the transparencies (7x10").

This is the first proof of the two plates: Side By Side (2013).  Typically I print an edition of six plus an artist's proof.  Here are a few more photogravures, all printed from individual plates and produced using the same technique.

Chemigrams in Prague and Brooklyn

Collins, Colorchart, 2012

If you were in Prague this fall and found yourself along the embankment called Smetanovo Nabrezi near the Charles Bridge, you could have taken a moment to drop in to the Hollar Gallery to see the New York printmakers show, which ran from Sept 18 to Oct 13 2013.  One of the works on display was a chemigram, Colorchart (2012) by Douglas Collins.  While there are many different ways to make a chemigram, this work is a good place to start in trying to understand some of the standard chemigram methods and strategems, as least as practiced by myself, a few but not all of my colleagues, and a number of my students.

The pictoral space here is organized as a grid, for simplicity - not a requirement but that's just how I often work.  My goal was to generate a random sequence of colors by allowing the chemistry in my trays, fixer and developer, to chip away at the tiny silver halide grains in the emulsion, changing the ways these grains refract light and thus selecting for certain wavelengths.  Since I knew we were going to generate an array of colors (geeky is good, but for a refresher look up the Mie effect on your own: it would take us too far afield in this post), what better way to think of it than as a color chart?  We're half way done.

The photographic paper I chose was Ilford FB warmtone and I coated it with MSA varnish by Golden - undiluted in this case, although dilutions are certainly permitted and can lead to different results.  (Actually everything is permitted but that too is another, quite wonderful, story.)  Once dry I incised in it a set of boxes, using a small blade, taking care not to go through the paper and prematurely end with tatters.  These boxes would become my color swatches in the finished work.

Next I proceeded with the 'dance of the trays', passing the prepared paper from developer to fixer to wash and back again - and again and again.  Did I say that all this can be done in daylight?  The basic chemigram method does not demand darkness, it's only in hybrid practices involving stencils, drawings or photo negatives that you may need to work under safelight, or in pursuing solarization effects or other variants; Christina Z. Anderson's book is a useful review of these methods.

After a certain time, when you start to think you screwed up and nothing's going to happen, things do happen.  Bits of varnish start to lift, at corners usually.  After a few minutes more will lift.  You can intervene here with a pair of tweezers and pull the rest off - or you can leave it to desquamate on its own.  If you decide to let the sections of varnish shed by themselves you will soon receive a bonus: the loose ends of varnish, flopping around on their tethers, generate a wispy color of their own, a kind of imprint of their brief existence.  That accounts for the strange outlines around some of the boxes in Colorchart and adds to the overall character of the work, a lyricism maybe, I'm trying to be modest.

Finally, when you feel the colors are right you plunge the paper, not without trepidation, into fixer for a last time, but be attentive here because the fixer may squelch everything, all the vibrancy you thought you had: some bypass this step and go directly to a long wash.  (See the post on Jeff Robinson, January 2011.)  Then you dry and you're done.

Nikolova, untitled, 2013

A very different way to make chemigrams is by using the so-called soft resists, materials that disintegrate or lift off almost immediately.  Eva Nikolova makes surprising use of some of them found in the local delis of her uptown Manhattan neighborhood, and in doing so has extended the expressivity of chemigrams in unforeseen directions.  "I draw," she says, "mostly with peanut butter and guava paste (a Dominican favorite), using pieces of mat board and credit cards, alongside the customary sticks and Q-tips.  The guava paste behaves exactly like honey except it has a stiff granular texture and doesn't spread, so it's easy to control.  What you are seeing is just the interplay of simple additive and subtractive drawing transformed by the chemical process."

I have to stop here: this is too astonishing.  To build the ruined cities that continue to haunt her, these fragments torn from dreams - go see the rest of her work on her website - with the most humble and ruined of tools gives the whole enterprise an unexpected pathos.  It is consummately eloquent.  It makes one think of Piranesi's Imaginary Prisons or maybe one's own nightmares, and yet it's a chemigram.

The medium and the message

Turnbull, Untitled, 2013

On returning to the Manhattan Graphics Center darkroom in New York after the standard summer wanderings and inner retreats, I did what I usually do after an enforced absence: inventory the mysterious bottles and containers that have accreted on the darkroom shelves since Doug Collins and I first began our chemigram investigations (2010 for me, I think 2009 for Doug) and wonder what on earth some of this stuff is and what it does. In the Endless Quest for Usable Resists, Doug and I have sampled many varnishes, gel media, glues, honeys and Ominous Gloppy Substances and eventually limited ourselves by process of elimination to those potential resists that offered the possibility of hard lines and at least some control over the results (though as always with chemigrams, control is never absolute and quite often not desired). Many substances did not pass the test and were left to rest peacefully in their containers at the back of the shelf until the Elder Days end and Them That Were Here Before Us return to rule what was once theirs.

One of our early experiments, probably suggested by Nolan Preece, was a bottle of Pledge Floor Care Tile and Vinyl Floor Finish with Future Shine, a mouthful of a floor care product that in Nolan's capable and practiced hands produced some fine and intriguing results. Our bottle of Pledge Etc. has sat mostly unmolested for over a year and a half now, since neither Doug nor I was able to make much sense or use of it. After meeting Nolan and seeing some of his Pledge-work first hand earlier this summer (several accounts of the World Congress of Chemigramists can be found in posts below), I felt the urge to return to this hitherto misunderstood material, but this time I had the assistance of e-mailed instructions from Nolan himself, who outlined several important considerations. Nolan suggested spreading a thin coat of the material on the surface of a taped down piece of photo paper with a foam brush, then applying textured objects to the surface and weighing them down while the Pledge dries (about ten minutes). After this, remove the textured objects and blow dry the paper's surface for 5-10 minutes. Process as you would any chemigram. The image above was processed in just this manner; I used a piece of crumpled paper towel as a textural surface. Nolan warned me that things happen fast in the developer and fixer, and indeed it seems like Pledge Etc. acts more like a soft resist than a hard resist and that to preserve white areas the chemigram is best first dipped into fixer for a few seconds (but not too long, or you won't get much in the way of darks once you move on to developer).

Turnbull, Untitled, 2013

This next image was processed on the same evening as the Pledge experiments but this time I applied a coat of Windsor and Newton Acrylic Gloss Medium (also orphaned on our darkroom shelf), a thin, milky medium that I used undiluted. It dried in about half an hour, with the help of our faithful darkroom blow dryer. I drew a quick freehand grid on the surface of the dry medium with an Xacto knife and processed in the same way as the Pledge image, i.e. a few seconds in fixer, then developer until the "desired results" were achieved, then back to fixer and then a water wash. What's interesting here is the way the developer attacked the carved lines and produced small visual eruptions along the lines, as well as the mottled areas of color that formed between the lines themselves. The paper here, as in the Pledge image, is an RC paper called VC Select. I'm assuming that the RC paper is responsible for the muted though elegant palette in both these chemigrams, and that FB papers would show a greater and brighter range of colors.

I certainly wouldn't claim either of these chemigrams as anything more than an experiment, but they were important in their own way. Many of us find particular resists and working methods that produce results we enjoy and admire, and I think we often tend to work within fairly narrowly defined boundaries. Here's a case where I went back to two materials long abandoned (for reasons neither Doug nor I can remember clearly, other than at the time they "didn't work") and discovered a kind of fresh potential. I look forward to revisiting other early "failures" and finding out what other potentials I may have overlooked.

A treat for the dog days

Preece, Chemigram Texturology, 2013

It's the end of summer, the dog days they call it, but here on the Monterey Peninsula these are glorious days, hardly a cloud in the sky, perfect temperatures for humans on earth.  The sea churns on the rocks at Point Lobos as always, and if you peek through the pines you can just catch sight of whiskered sea otters bobbing in the waves beneath the cliffs, sometimes joined, incongruously - but there is so much of that it seems natural - by a seal or a kayaker.  Further inland in the mountains where I live, the red-tailed hawks glide on the afternoon thermals in the canyons, their magnified silhouettes skittering darkly over chaparral.  At sunset a great horned owl appears and below, a bobcat or a skunk slink about to claim the meadow where earlier had grazed deer and turkey.  My neighbor Mike has called his goats to their pen and his chickens to their coop.  Soon the first evening stars will appear but it's not toward Pegasus in the east that I'll be drawn tonight - that's easy pickins - but to Arcturus and Spica low in the west, where with luck I'll see not only Saturn but Venus too, goddess of love, the bright queen of the sky of the Babylonians.  She'll be low on the horizon so for that I'll have to climb the ridge.  Dog days indeed.

Yet this will ease my conscience at not doing any cameraless photography this month, and I will not hide my excuse: the bees have established a hive in the old shed where I keep my workbench and I am prevented.  I think I should go down the valley to visit Bobby Bashir or Jeff Robinson to fire my enthusiasm and remind me of what I miss.  Or Martha Casanave, who met me at the Portola the other day when we talked about her new book, Trajectories, which continues, in the months I've had it, to leave me with an uncanny tang of absence (strangely biting and attractive if I can speak like that), the absence of others and of ends to stories.  An aching, extremely beautiful book.

And then a gift arrived from Nolan Preece, a new chemigram.  Here it is, up above.  "Eee-gads!" cried Martha.  It's a sort of cavalcade of his own favorite chemigrams from recent years, woven into an elegant grid of chemigramic portals.  The whole affair seems destined to open a new chapter in what a chemigram is and can be.  We'll get the details from Nolan another time.  For now enjoy, it's the end of summer.

Pierre Cordier & Gundi Falk at Von Lintel

Cordier & Falk, CH 17/9/11 Pair-Impair, 2011

Pierre Cordier and Gundi Falk have been collaborating in Brussels on new chemigrams for nearly two years, and now are presenting a selection of them in the group show called Unique, at the Von Lintel Gallery in New York until July 12, 2013.  In keeping with the theme, all the works exhibited are one-of-a-kind - there is no editioning here, no labels saying archival pigment print.  Whether that is a good thing or not is debatable, but one thing is certain: it serves to keep prices high and the collectors' interest still higher.  Indeed, the two Cordier-Falk pieces in the main room were sold to a major midwestern collector before the show even opened.

 Cordier & Falk, CH 20/9/11 Impair-Pair, 2011

What can we say about these new chemigrams?  That they harken back to the best, most vigorous Cordier style of grid-based work of 30 or 40 years ago?  This is true.  He is a master and a master is entitled.  But there are other rewards.  If you look closely (and what chemigram doesn't demand that?) you will see the delicate nuances and sly choices that gives his work its special character and make it vibrant and seem so very new.  When to stop a bubble from growing?  What shape must a line have?  How many squares are enough?  Momentous questions that lead to the meaning of art perhaps.  One also feels a muted, defining presence of Falk in this but it is hard to be more specific; how these two coordinate responsibilities reportedly varies from project to project and yet, to my eyes, appears seamless.

It's an important show to catch for the chance to see the Cordier-Falk collaborations, really for the first time in America.  Let us hope there will be more.

Discovering new (old) papers: Luminos

fig. 1 Charcoal R

To a darkroom maven, there's nothing like discovering a paper you've never used before and which, as sort of a gift from the photographic gods, displays qualities both unexpected and lovely.  One such for us recently has been Luminos, particularly the Charcoal R and the Tapestry X.  It began when my friend Lou Spitalnick let us have some of his old stock from the house he keeps at the end of Long Island.  "Go ahead, take what you want," he said.  Was his smile a knowing one?


We did.  Rich Turnbull was first to have at it and created the Charcoal R images in figures 1 and 2.  It turns out it's a warm-tone, fiber-base paper, probably a chlorobromide emulsion, but that's not what stands out.  First, it's the texture.  Charcoal R has a rough texture, rather similar to certain varieties of printmaking paper.  You pass your fingers over it and they tingle: the surface speaks.  But the paper's architecture has another secret, and that is that the emulsion seems to be buried deep within it, not at the surface.  Did the Luminos people plan on an unsized, highly absorbent paper, like a waterleaf paper?  That seems to be the case, because the images you get from it have a hazy, muted cast, as if they were peeking out shyly from a forest of paper fibers.  In the case of colors, this produces a whole range of tones and qualities new to our experience.

fig. 2 Charcoal R

fig. 3 Tapestry X

Tapestry X has the same formulation, with the difference that the paper has been given a more pronounced, canvas-like feel, an artsy effect popular in the years after WWII - witness now forgotten names like Wellington Art Canvas, Velour Black, Athena Old Master, etc.  Note the grain of the texture.  The problem with using this paper for chemigrams however is this, that it's so unsized your varnish resist just sinks in and apparently cannot form a tight varnish-emulsion bond, essential for the elaboration of incisions and mackie lines.  Its beauty is its curse.  One solution is to apply multiple coats of varnish, letting each dry in turn, so that you build up a scaffold of varnish material to work with.  Without this the varnish won't adhere to the emulsion; you'll get scumbling and lifeless incisions, as seen in figure 4.  (Some may actually favor this, of course!)

fig. 4 Tapestry X

Luminos production began in 1947 and was discontinued in 2005, probably under the onslaught of the 'digital revolution' although their press releases at the time spoke of paper supply issues.  Luckily, the papers are still available online.  Or, if you have more time than we have, you can make your own, mixing potassium and silver salts with gelatin and a paper of your choice, with details on the internet.

Chemigram summit in New York

It was Sunday night June 2, and we were five flights above West 40th Street, more than a dozen of us gathered from three continents, practitioners of the subtle art of the chemigram.  The elevator had broken and you had to climb up a sinister, badly lit stairwell, but no matter: Pierre Cordier was here on a rare visit to New York, holding forth, making pronouncements, examining work brought before him like so many offerings.  Others will summarize and analyze the evening, there is time for that, and substance aplenty to animate future discussions.  At the outset, the simple fact of his presence (as though mythic) was enough to dazzle and beguile us, while as the evening wore on his spirited banter put us more at ease and each of us were allowed privately to wonder at how fortunate we were, all of us, to be together.  It was indeed an historic moment, sixty-one years after Cordier's invention.
