Hi, Aidan,

If your commercial blue marking ink is too thin, how about leaving the cap 
off for several days until it starts thickening due to evaporation?  We use 
Bradley inks, and got frustrated with the inks getting TOO thick, because we 
used to keep the lids off during gross for quick dipping.  Another idea 
would be to use another ink color instead.  Blue and black inks are always 
thinner.  Orange and yellow inks are the thickest.
