Experiment Title: Test 6 – Change of Adhesive – Acrylic and Elmer’s Glue
Experiment Goal: To see if using a mixture of acrylic paint and Elmer’s glue works better to hold the mesh to the matrix than acrylic paint and water. We are trying to eliminate issues of the mesh peeling off of the plate while printing.
Plate Preparation: We mixed acrylic paint with Elmer’s glue at a ratio of about 60/40 and used that to adhere the Silkscreen 160 mesh to the PETG plate. We painted it on with a brush and used another piece of PETG to scrape away the extra paint mix. We then coated the plates with three layers of emulsion and exposed them for five minutes.
Evaluation of Plate Preparation: The paint and glue mix was definitely thicker than the paint and water mix. We looked at the plate under a loop before applying the emulsion, and did notice that some of the holes of the mesh looked filled in, so we are wondering if in the future, it may be a good idea to still add some water to thin the mixture.
Conclusions: A large amount of the emulsion rubbed off that was not supposed to. We did not print these plates, as we knew that they were going to have the same problem as the previous few tests where the plates did not hold ink well and became over wiped easily due to large exposed areas of mesh. We also had already decided to move on to doing a bunch of smaller tests of many different adhesives, which is detailed in the next experiment, Test 7.
