1. An inkjet printhead adapter, comprising: a chassis operative to accommodate at least one printhead; andcomprisesat least one pigmented ink recycling valve; andat least one pigmented ink supply valve communicating with an ink reservoir via an ink feeding tube and with the at least one printhead accommodated in the adapter, the ink supply valve being operative to direct a flow of pigmented ink from the feeding tube to at least one of the at least one printhead and the pigmented ink recycling valve;at least one washing solvent draining valve;at least one washing solvent supply valve communicating with a solvent reservoir via a solvent feeding tube and with the at least one printhead accommodated in the adapter, the solvent supply valve being operative to direct a flow of solvent from the solvent supply valve through the at least one printhead to the washing solvent draining valve. 2. The adapter according to claim 1, wherein at least one of the solvent feeding tube valve and the at least one draining valve is operative to direct a flow of solvent through at least one of a main ink channel and a printhead nozzle. 3. The adapter according to claim 1, wherein the pigmented ink comprises micro and/or nano-particles of at least one of pigment, glass and ceramics. 4. The adapter according to claim 1, wherein the ink supply valve and ink recycling valve are operative to allow continuous recycling of the pigmented ink and maintain pigment particles in suspension. 5. The adapter according to claim 1, wherein the adapter also comprises a network of tubes at least part of which are at least one of an integral part of, or passageways within or external to the chassis. 6. The adapter according to claim 1, wherein at least one of the pigmented ink supply valve and the pigmented ink recycling valve are placed in close proximity to printhead nozzles to minimize a volume of a column of ink between one of the valves and the printhead nozzles to a volume less than 5 ml. 7. The adapter according to claim 1, wherein a volume of a column of ink between one of the valves and the printhead nozzles is less than 4 ml. 8. The adapter according to claim 1, wherein a volume of a column of ink between one of the valves and the printhead nozzles is less than 3 ml. 9. The adapter according to claim 1, wherein the chassis further comprises at least one of registration pins and registration pin holes. 10. The adapter according to claim 1, wherein the adapter is spatially calibrated relative to a printer at the adapter manufacturing level and at least one of registration pins and registration holes are placed at locations determined by calibration/alignment process. 11. The adapter according to claim 10, wherein following calibration/alignment only the adapter is calibrated relative to the printer, wherein a batch of printheads directly attached to the adapter is automatically calibrated accordingly. 12. A method of printing with pigmented ink, comprising: providing at least one pigmented ink recycling valve;providing at least one pigmented ink supply valve communicating with an ink reservoir via an ink feeding tube and with at least one printhead accommodated in an adapter;directing a flow of pigmented ink from the feeding tube to at least one of the at least one printhead and the pigmented ink recycling valve;providing at least one washing solvent draining valve;providing at least one washing solvent supply valve communicating with a solvent reservoir via a solvent feeding tube and with at least one printhead accommodated in the adapter; anddirecting a flow of solvent from the solvent supply valve through the at least one printhead to the washing solvent draining valve. 13. The method according to claim 12, wherein the pigmented ink comprises micro and/or nano-particles of at least one of pigment, glass and ceramics. 14. The method according to claim 12, further comprising continuously recycling the pigmented ink to maintain pigment particles in suspension. 15. The method according to claim 12, further comprising: positioning the pigmented ink supply valve and the pigmented ink recycling valve in close proximity to printhead nozzles; andminimizing a volume of a column of ink between the valve and the printhead nozzles to a volume less than 5 ml. 16. The method according to claim 12, further comprising minimizing a volume of a column of ink between one of the valves and printhead nozzles to a volume less than 4 ml. 17. The method according to claim 12, wherein also minimizing a volume of a column of ink between one of the valves and printhead nozzles to a volume less than 3 ml. 18. The method according to claim 12, wherein the printhead comprises at least one main ink channel and at least one nozzle, and further comprising directing a flow of solvent through at least one of the main ink channel and the nozzle. 19. The method according to claim 12, wherein also at a manufacturing level: spatially pre-calibrating the adapter relative to the printer; andplacing at least one of registration pins and registration holes at locations determined by calibration/alignment process. 20. The method according to claim 12, further comprising: directly attaching the at least one printhead to an insert; andspatially calibrating the printhead relative to the adapter so that when the adapter is calibrated relative to printer an attached batch of printheads is automatically calibrated accordingly. 21. An inkjet printhead adapter, comprising: a chassis operative to accommodate at least one printhead, the chassis comprises: at least one washing solvent draining valve;at least one washing solvent supply valve communicating with a solvent reservoir via a solvent feeding tube and with the at least one printhead accommodated in the adapter, the solvent supply valve being operative to direct a flow of solvent from the solvent supply valve through the printhead to the washing solvent draining valve. 22. A method of printing with pigmented ink, comprising: providing an inkjet printer including a printhead adapter, comprising: a chassis operative to accommodate at least one printhead, the chassis comprising: at least one washing solvent draining valve;at least one washing solvent supply valve communicating with a the solvent reservoir via a solvent feeding tube and with the at least one printhead accommodated in the adapter; anddirecting a flow of solvent from the solvent supply valve through the at least one printhead to the washing solvent draining valve.
