Photo Forum / Film Photography / Darkroom / May 2004processing a film on a canvas
Would somebody know how to process a film on a canvas? Is that possible? Tkx On 5/3/2004 8:23 AM YvanB spake thus: > Would somebody know how to process a film on a canvas? > Is that possible? I assume what you mean is make a *print* on canvas, right? Sure: brush on liquid emulsion. Expose. Develop.

Expose. Develop. Or, alternately: Optionally coat canvas with gelatin size, and then sensitize with van Dyke, Kallitype, Platinum/palladium, cyanotype, salt print chemistry, etc. and process accordingly. Unfortunately, except for liquid emulsion these processes are all both very slow and primarily UV sensitive, which pretty well eliminates them for projection enlargement. If you want a BIG print on canvas using, say, cyanotypy, you need to first make a BIG enlarged negative, which usually means enlarging a positive on print film, then contact printing that to make a negative in the final size, which is contact printed to the alt process medium using sunlight, fluorescent or mercury vapor UV sources.

SignatureRobert D Feinman Landscapes, Cityscapes and Panoramic Photographs http://robertdfeinman.com mail: robertdfeinman@netscape.net I think there are at least a couple of firms that make canvas based printing materials. (Luminos, for sure, and I'm sure I've seen at least one other.) They are expensive but pretty trouble free. > > Would somebody know how to process a film on a canvas? > > Is that possible? > > Tkx > > > Many "canvas" prints are just printed on textured paper or have > a textured coating applied afterwards. Two possibilities Luminos makes photo linen, "...Luminos Photo Linen is a real cloth coated with a projection speed, black and white photographic emulsion that responds to conventional B&W treatment. ..." I've played with this stuff in the past and it has possibilities. Available in sheets and 50" rolls. http://www.luminos.com/ttlinen.HTML And a VC emulsion in a bottle from the same company: http://www.luminos.com/flexicon.html Signaturedarkroommike ---------- > Would somebody know how to process a film on a canvas? > Is that possible? > Tkx Yvan asked - >>Would somebody know how to process a film on a canvas? Is that possible?<< Yvan, I'm not sure if you mean to mount a print to canvas. If so, many of the replies gave more difficult and expensive ways to accomplish this. Just make the print on RC paper, B&W or color, then strip off the back layer of resin support and dry mount the print to canvas using a special liquid adhesive. Color labs do this all the time. The pressure in the dry mount press squeezes the print into the canvas so it takes on that texture, then it is stretched over a wood frame and stapled.

Um, how do you "just strip off the back layer of resin support"? This sounds like a non-trivial undertaking to me. SignatureI was quickly apprised that an "RSS feed" was not, as I had naively imagined, some new and unspeakable form of sexual debauchery practised by young persons of dubious morality, but a way of providing news articles to the cybernetic publishing moguls of the World Wide Wait so they can fill the airwaves with even more useless drivel. - Cynical shop talk from comp.publish.prepress David asked: >>Um, how do you "just strip off the back layer of resin support"? This sounds like a non-trivial undertaking to me.<< No, it's not trivial and it does take a little practice (preferably on scrap prints). Just use a sharp X-acto type knife blade to peel up a small corner of the backing (plastic resin coating), then gently pull it away from the print. What is left is the print with a thinner raw paper base, which can be mounted onto canvas. Some people like to roll the corner up on a dowel and roll across the print. This method provides less chance of damaging the print and maintaining an even peel. Bernie > David asked: >>Um, how do you "just strip off the back layer of resin > support"?

You simply apply a laminate to the top of the print, Put it in the hard bed press for 2 minutes and remove it and peel. The RC surface adheres to the laminate, the emulsion is much thinner then the above method. Then just place the emulsion with the laminate on a piece of canvas, wood, foam, metal, glass, etc. with a piece of double sided laminate and place back in the press for 2 minutes.

You could also buy some Liquid Emulsion and "paint" it onto a piece of canvas, use your neg and enlarger and process it as you would with photo paper. This may already have been suggested, as I have missed a few posts on this group lately. Brian.................... |
