1. New acrylic stamps may have some residue left from manufacture that needs to be cleaned off. It will wear off in time but to speed up the process use a clean pencil eraser over the stamps. Papertrey Ink had suggested this in their instructions but I actually found it more necessary on the another companies set.
2. When stamping with this new stamp before using the eraser, Papertrey's Hybrid Ink worked the best. Stampin' Up's Craft Ink was the next best in adhering to acrylic. Dye inks like SU!'s Classic Ink pads performed the poorest. (I have also found Stazon Ink to work great on Acrylic but because it stains my stamps and has a limited color selection, it is not my first choice.) Dye inks, such as Stampin' Up! classic and Ranger, are great for distressing.3. To get dye ink to adhere to acrylic, stamp first in Versamark and then in dye ink. The Versamark gives the dye ink something to cling to. I can't remember where I heard that wonderful tip but it works. In this photo, the card on the left was my first stamp from this set. The one on the right was made using this technique. Both are stamped in SU!'s Riding Hood Red classic ink on the same cardstock. You will always get better results with SU! products on their whisper white or very vanilla cardstocks than on colored cardstock.
These are just my experiences with a few acrylic stamps. I plan to continue my experiments to decide which type of ink I want to invest in future. Also, I want to do more experimenting on a variety of surfaces. Pigment Ink, such as Stampin' Up! craft, has proven very good on a variety of surface in the past. I'd like to try the fluid chalk and hybrid ink's as well.
