What is a correct formula for gelatin+glutaraldehyde paper sizing

Job Westerduin
 

Hi, i have experimented with gum printing (trail and error,, and i will to start serious first gum printing with a cyanotype as starting layer base this weekend or later.

I have a pot glutaraldehyde from Rollei Black Magic emulsion set, that was left over from my previous silver photopaper enlarging hobby.
How many glut and gelatin per 1 liter water.

Greeting Job from The Netherlands.

...sorry: aluminum rod instead of plastic... (plastic is likely to work as well, I assume)

Re: Coating gum

Hi all,
René Smets, a member of our Picto Benelux group, uses yet another system for his carbon printing: he uses a plastic rod into which he can insert spacer blocks corresponding to the desired thickness of the coating, and an aluminium plate with a "window" corresponding to the image size, which prevents the emulsion from spilling into the margins. I hope that by attaching his sketch to this email, he will find his way to you :-)  If not, you can find it in the document at this address (p4): https://www.picto.info/oildoc/Oil_RS.pdf

Best,
Jacques

Mario Fdez.,
 

I use Krita (www.krita.org), and I am quite satisfied.
Highly recommended.
Kind regards.

Check out Gimp.  I know a number of people who use it very successfully for alt negatives including color separations.

Re: Alkaline fixers and lumen prints

I have made uranotypes since 2012 and, framed under glass, you would need a scintillation counter to read either the small amounts of Beta or Gamma coming off a print.  They are too weak for a Geiger counter.

Good morning!

(I am SO thrilled we can post pix).

I’ve been running a lot of lumen print tests to quantify some things, one of which is the use of an alkaline vs acid fixer to reduce fading of the colors.

I’ve done two tests now with an 8x10 Stouffers, exposed outside all day 9-6 full sun, print then cut in half, one fixed in Sprint (6 pH) and one in Formulary TF-4 (8 pH). The first time I did this I was very surprised to see a slight difference—a bit lighter color—in the alkaline fixed half.

So I did the test again and sure enough, same thing. Left is alkaline, right is acid.

I’m going to do a couple more of these on different papers but if it were based on these two tests alone I can’t support the theory of an alkaline fix reducing fading of colors. (Note: prints are still wet here and have not dried down to full darkness but the other test dried down was exactly the same, also different paper).

Has anyone else done this too? Does anyone have acid and alkaline fixes and can do a side by side? I’m going to use citric and sodium carbonate to “prime” the two fixes and do it again, too..both of the fixers I tested are ammonium thiosulfate with added ingredients.

I will measure densities with a densitometer to make sure it’s not just a color shift but an actual density dif, too.

Chris

Re: Alkaline fixers and lumen prints

Chris,

My friend Dan Herrera says he doesn’t even look at his lumens until they are fixed so as not to get his heart broke lol. I agree, some papers look better fixed, but others not so much. I’m using the green tea in experimental photo work on porcelain surfaces and it does encapsulate as nano particles so that the gold at least can be fired in a kiln. Trying a hybrid chrysotype approach. I figure a side benefit may be that they fix the lumens by doing the same. I will definitely let you know, because it would be a) very non toxic and b) too easy if true LOL

I’ll be following this thread with interest!
