Mural printing

[Dwayne Martin]

Are any of you making big prints? Like 40x30” or more? If so what equipment are you using to do it with? I have been lately. I started with a sheet of plywood with a layer of sheet metal glued to it, and strip magnets to hold the paper down. I found that to be really tricky to deal with so I built myself a two bladed easel capable 30”x 48” exposed area. I’m curious what others are doing. My enlarger is a D5 that I converted to 8x10 with klaus lundsgaard’s conversion kit. My stand is basically a old super heavy duty commercial model with a table that drops all the way to the floor…

And you're here asking questions as to how it's done? Sounds like WE need to be asking YOU. My first question would be how to afford a few sheets of 40 inch photographic paper without ending up in the poorhouse. From there, it's a matter of being a cabinet maker or carpenter to fabricate the needed things. Sounds like you got it going on already, and no I'm not being a troll with my post. Regards and good luck

The important things I've found are: getting the relevant optimised lenses (Rodagon-G or G-Componon) if needed for your relevent size of enlargement; working out a means of paper handling that works in your space (not least as roll dispensers were so comprehensively scrapped about 15-20 years ago that they currently are about as easy to find as rocking horse excreta, and when one does appear it sells in minutes); and ensuring that you have a means to wash and dry (ideally taped out under tension) the resulting print. Some real brute power from the enlarger can help too.

I’m using a 240mm Rodagon G for 8x10, and a 135mm Companon S for 4x5. Even at 30”x40” the results with the Componon are good but my style of photography allows for that. I’m Rolling the prints in 24x30 trays. Not sure what others do but I make two rolls with the print then twist back and forth keeping as much paper flat in the tray as the space will allow. Then I tone out side using a pool to wash made from a sheet of plastic and 4x4’s or a border. I learned the hard way you can’t roll a print in bleach, atleast not a mat sheet of Ilford lV. It won’t tolerate the friction involved in the rolling. I ended up finding a use tray for the purpose, it’s about 36x58. It was made for some industrial purpose and was relatively inexpensive.

For murals, I do horizontal exposures. My Beseler 45MX flips easily to horizontal and I have an 8'x5' easel (foam-core in a wooden frame) hanging from hooks on the ceiling. I use masking tape on the edges to keep the paper in place. Processing is in four, 5-foot long, half-tubes -- created from 12" PVC pipes. I use a 50mm Rodagon G for 35mm, and a 150mm G-Componon for 4x5.

Since your enlarger does not have horizontal printing, you can attach a 45° front surface mirror to the lens, such as a Spiratone Mirrotach -- very inexpensive.

Interesting, I also have the Beseler 45mx back to back with my D5. The reason I opted to go the floor route is the trouble of moving things around to set up the Beseler horizontal. That mirror idea is a good one…

Whether flipping the enlarger or using a mirror, you have to have enough space between the enlarger and easel to make the size print that you want. You're lucky, you have a high ceiling. Going horizontal was my only option.

Giant pictures of beautiful women! I wouldn't be able to get away with that

I have a beautiful 8x10 enlarger setup that I haven't used in a long time. It's not going to waste as I have a couple things planned. I doubt I'll be going beyond 20x24, more likely 16x20.

I make no effort to sell prints so I don't know what I'd do with too many of these.

30X40 inch is hardly mural size. And if you're enlarging 8x10 film, or even 4x5, the degree of magnification does not call for any kind of special enlarging lens like a Rodagon G. I have a variety of enlarging lenses, including the 240/9 and 305/9 Apo Nikkor process lenses for 8x10, which are better corrected than any kind of official enlarging lens. For 4x5, I mostly use a 180 Rodagon and 150 Apo Rodagon N.

There was a time when I used a horizontal enlarger for 30X40 prints, along with a vacuum easel on the wall. Now I use a couple of tall vertical 8X10 enlargers instead, in a room with a high ceiling.

I have set up my darkroom to do 30 x 40 inch murals in Silver and PT PD , I live work in a long narrow building and we have a fantastic basement with floor drains that lead out. to a back yard .
I have built a 30 x 40 washer and am very excited to put it to use later this summer. We have a 11 x 14 Devere which is located in the center of the darkroom and we actually cut a hole in the ceiling and the enlarger head actually can lift up into the main floor. This enlarger is very unique as its focus is controlled at the baseboard , so its a dream to focus. For this enlarger we will dedicate to only 4 x 5 and up to 11 x 14 films . We have a second Omega Condensor enlarger which we use for mural 30 x 40 and small prints due to a Baseboard that can be driven by hydraulics to variable position- this enlarger is for 35mm and medium format film. We just finished a show that required 30 x 40 inch prints and 20 x 24 inch prints from 35mm and it was a breeze.
For the PT Pd and multilayered Gum over pd prints we can go up to 30 x 40 inches as we purchased a 32 x 44 inch LED exposing unit from Cone Editions which we attached to the base vacumn frame of a 30 x 40 Nuarc plate burner.

I am very happy with this size and really see no reason to go larger as its a real PIA , quite doable but not my cup. of tea these days.

In my past life I was a mural printer at a very large mural house called Jones and Morris Murals in Toronto and I learned how to use huge horizontal Durst Enlargers to make up to 10ft by 60 ft murals in 72 inch strips.
Its much easier today to cap off a size due, to space , trays , water usage. If I have to make larger prints I use Griffin Editions in New York who do monster silver prints via enlarger or Lambda.
