Ink Mixing Tips

ICN-1501 Digital Scale

Follow these steps to achieve best possible ink mix:

  • Make sure you use unlined mixing cups (no wax) and wooden or metal mixing sticks! If you use plastic, your ink may get contaminated with plasticizers.
  • Zero the scale out and make sure its on a leveled surface.
  • Add the appropriate hardener or axillary ratio (4:1 or 10:1 for 1000H=25%. 20:1 for HGL=5%)
  • After adding the thinner, pour the ink into the mixing cup using no less than 40 grams since it doesn’t flow very well in the ink cup or inkwell once it’s mixed.
  • Add appropriate hardener ratio. For 1000H, depending on the ink series, the ratio is 4:1 or 10:1 (4 parts of ink to 1 part of hardener or 10 parts of ink to 1 part of hardener). For HGL, the ratio is 20:1 (20 parts of ink to 1 part of hardener).
  • To keep from over thinning, continue to add it drop-by-drop. If you add it all at once it tends to “shock” the ink and it’s always easier to add than take away.
