Frequently Asked Questions
Which Formax printers use AP-series ink?
The AP20 through AP28 cartridges are chipped exclusively for the Formax AP2, AP3, and AP4 addressing printers. They will not work in other models. If you have a different Formax printer, please check the correct ink category for your model.
How do I choose the right AP ink formula?
Match the ink formula to your media type: AP20/AP21 for non-porous and UV coated surfaces, AP22 for a wide variety of media, AP23 for coated stocks, AP24 for aqueous varnished materials, and AP25 when fast dry time is a priority. Contact our team if you need guidance on which formula fits your specific application.
What are the spot color inks (AP26/AP27/AP28) used for?
The AP26 (Blue), AP27 (Red), and AP28 (Green) are pigmented spot color inks for applications where you need a color other than black for addressing or personalization on the AP2, AP3, or AP4. These are pigmented formulas for good opacity and durability.
What is the KAO Collins Sigma+ TSK3646-45si?
The KAO Collins Sigma+ is a high-performance black solvent ink cartridge compatible with HP45si print technology. It is not an AP-series cartridge — it is sold separately and fits printers that use HP45si print heads. It is designed for non-porous surfaces including plastics, films, metals, and glass, with long decap time and strong adhesion.
