    Probleme Carbon With Indian Ink

    Hi all the Carbon Printer,

    I have a problem with my carbon printing.
    I use gelatin and India ink

    On my carbon, I see a small black dots as
    if there were black specks and very small.

    I do not know why and I can not find the solution even by filtering the India ink knowing that I use gelatin and still liquid India ink.

    Someone on the forum have had this problem with India ink and you have a solution?

    Thank you for your Help

    Philippe

    Is it possible that it's undissolved sugar, or undissolved gelatin granules? I had a similar problem, more heating and stirring solved it.

    I had a similar problem when I used an old bottle of Speedball ink that my school was going to dispose of. Switching to a new bottle solved it.

    Isopropyl alcohol an cause the ink particles in glop to aglomerate into little grains. Use less IPA and mix it 50/50 with water, if you are using it. I sometimes use 50ml/liter of glop cut with water if I am in a hurry, but the bubbles will go away on their own if you wait long enough.

    I do not use isopropyl alcohol but I use liquid soap.
    Do you think the problem may be liquid soap an cause the ink particles in glop to aglomerate into little grains.
    Should we remove the liquid soap? Is it useful or not?

    Thank you for your advice to all

    Hi Philippe,

    Many modern liquid soaps are not really soap, they are synthetic detergents, and they do not necessarily behave in the same way as true soap does. I use soap in my recipe, but I make my own soap and use soot as the pigment. As you are using Indian Ink, a soap-based glop is not needed; try using isopropyl alcohol instead to control the bubbles.

    Best regards,

    Evan

    Is it possible for the glop not use isopropyl alcohol and no soap.
    Soap is therefore essential if what product and brand can be used ?

    Could one use Methanol or Ethanol instead of IPA?? I'm planning to try Carbon printing but getting IPA in Belgium is a P.I.T.A.
    Sure, I could give you a boring explanation who I really am but I rather let the Origami do the talking.
