During cartridges refilling to laser printers, ink has to meet appropriate requirements at the angle of:

• chemical characteristics (dying or pigmental ink, composition)
• physical characteristics (surface tension , stickiness, pH coefficient and others)
• cartridge refilling process (appropriate cartridge balance, compatibility of used materials and appropriate refilling equipment)

Alternative inks are different from originals (OEM) as regards their characteristics (it is obviously dictated by product patent protection). The paper, obviously except ink, has the influence on the quality of the printout, therefore it is so important to choose appropriate carrier, which the printout will be transfered on.

According to recommendations mentioned above, OCP company produced the following types of pigmental inks:

A new generation of OCP pigment inks (BKP 245, BKP 249, BKP 251) with outstanding product features offers. These features are especially:

1. An excellent low "intercolor bleeding" - that means: bleeding between color inks and OCP's innovative pigment inks is not noticeable, maybe verifiable by measuring equipment.
2. The improved optical density is ensuring deep black printouts, which are not ranking behind the OEM, respectively they are partly overtopping the OEM printouts.
3. A high resistance against highlighters - after some minutes inkjet prints would not be interferingly smudged by customary highlighters. The resistance is compareable to laser prints.
4. A very high paper independence - this means: the printout quality does not depend noticeable on the quality standard of the used paper or printing media any more by using the new OCP pigment inks. Even upon plain, bluntly fibrillar 70gr papers the previously mentioned features such as high optical density and lowest intercolor bleeding are unrelievedly existing.

BKP 41

Black pigment based on the high quality of single particle used in HP cartridges type 51645, C6615, C4844 and HP 51640.The time of drying up, the level of blackening, the density and the durability on rubbing off are comparable with OEM inks

BKP 43

Black pigment based on the high quality of single particle used in LEXMARK cartridges type 12A1970 and 17G0050.The time of drying up, the level of blackening, the density and the durability on rubbing off are comparable with OEM inks. Can be administerd to the carteidge without sponge rinsing.

BKP 44

Black pigment based on the high quality of single particle used in Canon cartridges type BCI - 3 (e)bk, BCI - 6 bk and BCI.The time of drying up, the level of blackening, the density and the durability on rubbing off are comparable with OEM inks. Ink designed for OEM cartridges with sponges. In case of alterative cartridges refilling it is necessary to verify the sponge quality.

BKP 45

Black pigment based on the high quality of single particle used in Epson cartridges type T015-401 and T032-140.The time of drying up, the level of blackening, the density and the durability on rubbing off are comparable with OEM inks. Ink designed for OEM xartridges with sponges.

BKP 48

Modified version of BKP 40. In practice, the same chemical composition but with faster time of printnout drying up on the surface.Alternative to BKP 40 - if the customer has a high requirements with regard to speed of the printout drying up.

BKP 49

Modified version of BKP 41. In practice, the same chemical composition but with faster time of printnout drying up on the surface.Alternative to BKP 41 - if the customer has a high requirements with regard to speed of the printout drying up. Recommended to 5011, C6656 and C6627 cartridges refilling.

BKP 89

Black pigment based on the high quality of single particle used in HP cartridges type C8765 (No.94, 338), C8767 (No.96, 339)..The time of drying up, the level of blackening, the density and the durability on rubbing off are comparable with OEM inks. The ink producer (OCP company) has made a special formula of this ink - very high dark density and very high stability of chemical and physical features.

BKP 100

Black pigment based on the high quality of single particle used in Lexmark cartridges type 18C0031/ 18C0032The time of drying up, the level of blackening, the density and the durability on rubbing off are comparable with OEM inks. The ink producer (OCP company) has made a special formula of this ink - very high dark density and very high stability of chemical and physical features.
