We have found the following procedure to give the best and most repeatable results when it comes to our paper Microfluidics.
  1.  Pattern Design
When designing the microfluidic channels in inscape we found that .9 mm walls with 1 mm channels give the best results. In order to get full penetration through the paper with the wax we printed a solid black fill on the reverse side of the paper, this effectively halves the thickness that the wax on the pattern side has to penetrate.Â
 2. Baking
We used a laminator on the 3mm setting and rand the printed design 2-3 times through the laminator sandwiched in between parchment paper. Using a laminator is more efficient and repeatable then using a stove or hotplate as it heats both sides of the paper and heat coverage is uniform and consistent.
