Platinum Photo Pro is a high end resin encapsulated pigment ink (K3 Equivalent). Resin encapsulation of the pigment particle results in a reduction of print head clogging, increases UV life and decreases settlement.

Head Blockages - In very simplistic terms pigment particles are minerals and as such in microscopic terms they have very solid jagged edges. When these particles travel to the print head they quite literally catch on each other and the jagged edges can cause them to clump together (agglomeration) and form a physical blockage. Resin encapsulation is a process where the pigment particles are encased in a thin layer of acrylic co-polymer. When these balls of pigment reach the print head they 'roll' together and with no jagged edges to catch on they do not block the heads of the printer and are thus a more reliable ink to put through your expensive printer.

Increased UV Life - This micro-thin layer around the pigment particles absorbs a level of UV radiation in essence creating an additional layer of protection against UV light.

Decreased Settlement - The resin encapsulation insulates the static charge of the pigment particle. Traditional pigment inks are prone to settlement caused in part by the electrical charge of the particles drawing them together much like a magnet. insulating against the static charge better resists settlement.

Durability testing - inks are tested by freezing to -20c and then heated to 60c. This process repeated over an 4 week period (5 cycles per 24 hours) with no coagulation, crystallization, condensation, sediment or colour change.
