• RYNAN S550DK / S510DK / S500 series (S500DR, S500DB, S500DG, S500DO, S500PW, S500PW etc.) — Variants include solvent and mild solvent inks with long decap time, high optical density, sharpness and barcode readability; some variants are tuned for porous substrates or for pigment/white printing on dark substrates. Shelf life varies by product (examples: 12 months for porous formulations, 3–9 months for some solvent/white pigment items).
• 3020K / 3022R / 3020B / 3022 family (Aqueous) — Black dye aqueous inks and colored aqueous inks for porous and semi-porous media (paper, coated paper). Improved fade and water resistance for certain aqueous formulations; long decap time and good sharpness. Best before: typically 12 months from filling date.
• RYNAN A100PK — Aqueous black pigment formulated for wood printing; enhanced fade and water resistance (suitable: paper, wood). Best before: 12 months from filling date.
• RYNAN E100DC — Black pigment aqueous ink for wood with enhanced fade and water resistance.
• Security Inks — Invisible UV fluorescent inks (red, blue) in solvent or aqueous bases: invisible UV fluorescent red dye solvent ink, invisible UV fluorescent blue dye solvent ink, and similar aqueous fluorescent/security variants. Features: long decap time, sharpness, good adhesion; suitable substrates include PVC, PET, Metal, Aluminium foil (for solvent security inks) or paper/coated paper (for aqueous security inks). Best before: commonly 6–12 months depending on formulation.
