New information to share: inks for stamping on muslin (on muslin bags for shower favors, wedding bird seed for tossing etc.).
TPC Studio Clearly Better (formulated for use with clear stamps)
-dye and pigment blend stamp pad
-I used black on unbleached muslin and got a nice impression. The image is clear and is the darkest of the clean printing black ink impressions but is not a dark black impression.
-pigment stamp pad
-I used both black and cranberry Color Box ink pads on unbleached muslin. The black made a clean image which dried quickly but was quite light. The images was quite a bit lighter than the TPC Studio ink pad.
-The Cranberry ink (and I am assuming any color Color Box Pigment would have similar results) made a nice dark clean impression. The impression didn't dry as quickly as the black pigment did. This may mean that my black pad is older than the cranberry, but they are not production dated as the washable child safe pads are. I was able to smudge the impression a little with firm pressure, but pigment tends to dry completely over a longer period of time (a day or two max.) or with the application of heat. This color pigment impression really looks nice.
Encore Ultimate Metallic (Tsukineko)
-water soluble pigment ink pad
- The impression is nice and clean and dried quickly. The silver (metallic aspect) is less apparent than on paper making the impression appear gray. I think that gold ink would make a really nice impression on muslin with an antique bronzy look.
JMP Indexing Ink on a linen pad
-indexing ink intended to make permanent impressions on wood or plastic
-This ink made a clearly black impression, dries very quickly and will not be affected by exposure to moisture. However, the ink bled into the fabric.
-fade resistant dye ink pad
-I unfortunately only have a very pale pink Memento ink pad so it is a bit difficult to see the impression. It appears to be quite clean and dried quickly. Once dry this ink will not bleed and is water resistant. It dries more quickly and won't smudge as the pigment ink does.
So, with the exception of the indexing ink, any of the ink types works well to stamp on muslin. TPC Studio Clearly Better and Color Box seem to make the best impressions, with the TPC Studio Clearly Better drying more quickly and is listed as waterproof and permanent on fabric if set with heat.
