A cartridge's print quality (true and vibrant colors) and the amount of pages printed per cartridge (page yield) depend on how a cartridge is made or remanufactured, materials used (inks, sponges, consumable parts, etc.) and the quality assurance testing. To save money and increase profits, some companies use cheap low quality inks and materials and do not test their products before selling them to you. Our ink materials are directly imported from Formulabs of USA to ensure quality.
