QTR-Quadtone RIP

Ok thanks a lot Paul,

for all the information.
 I'll think you're right not to mix it myself,
 I just bought 3 pints of c6b with inksupply,
  however I find the transportidea is not very 'eco-nor-logical'...


I am curious.

    I have bought in 'inksupplycom' the black carbon ink but I didn't know they had the
    water glycerol solution to dilute.

    Can I make it myself with only destilated water and glycero? Where do I best buy
    the glycerol or do I need 99% pure or is the drugstore also ok?


  The MIS generic bases are so cheap, I'm not sure it's worth starting from scratch yourself unless you do a large volume.  If you are going to use or make the generic base, use the C6B version unless you are going to print on Arches uncoated watercolor paper with a 1.5 pl printer.  Then go to the C6C, which also does fine on inkjet papers.


  Dilution base is more than just water and glycerol.  The surfactants are critical -- a huge part of the game and where the OEMs use proprietary formulas they are not about to share with us.  The OEM products also have biocides in them and use a rather toxic form of glycol.  My blends were designed to use safer materials and surfactants that were readily available.  The quality of the water appears to also be a factor.  Some distilled water is apparently not very pure or has a pH that may be too acidic.  If the water sits around for a long time it can absorb carbon dioxide and turn acidic.  MIS uses buffered water, I believe.  (I did not find it necessary with the distilled water I buy from the local supermarket.)


  For the glycerol, I use 99.7% pure from a science supply house.  I think I have a link in the ink mixing PDF.  Low quality glycerol has also been an apparent issue for a few people.   See http://www.paulroark.com/BW-Info/Ink-Mixing.pdf 


  Good luck.
