Re: What is a correct formula for gelatin+glutaraldehyde paper sizing

Job Westerduin
 

Oh i have a idea to neutralize the paper afterwards with a  bath of baking soda+water..

Or is that noy good idea?

Hi thanks for answers,
I found a safety material sheet from Rollai-Maco from Germany. (Screenshot)

There is 2-5 pct of glut in there.
But the two another addidives might be give problems with sizing, this makes paper acid.

I coat 2  12x15 sheets at a time with just 100ml size plus 0.8 gm glut, using a coating rod to spread. A hot rod with eliminate bubbles in the sizing

More than that and you will start forming polyglut. Polyglut will give a yellow stain in the size and cannot be removed.
Very little glut can actually be used. Two active bonding sites on the glut molecule means a lot of crosslinking activity with gelatin

Re: What is a correct formula for gelatin+glutaraldehyde paper sizing

Guido Ceuppens
 

Christina beat me to it but I also have used 3% gelatin as size mixed with 6 ml glutaraldehyde (2,5 % solution) per liter. Measure the amount of warm gelatin solution needed and mix the glut in just before you size the paper. You can also use a two step method, but make sure you have a good ventilation!

Job,
I use 6 ml 2.5% glutaraldehyde per liter of 3% gelatin. So you’d have to figure out what the percentage of Black Magic is and then do the math. It takes so little glut.

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

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.
