1. Digital ink supply system :  This ink supply system is available for - SPECTRA, Xaar 128, Xaar 500, Konica, Seiko printhead based printers :

Proper ink supply mechanism is most essential part to be concentrated while designing equipment on DOD inkjet technology.  The proper ink supply system helps to utilize cost of printhead in terms of - MAXIMUM PRINTHEAD LIFE, FAST SPEED AT PRODUCTION SITE ALSO, TO MAINTAIN PRINT QUALITY  BY MEETING REQUIREMENTS OF PRINTHEAD, TO SAVE THE INK COST & TROUBLE FREE OPERATION.  The high quality ink supply system is required for the follows:

• To utilize full life of printhead : The printheads are very expensive part of wide format printers hence the under utilization of printhead's life, will effect the production cost. The economical versions of printers upon sub-tank technology can hardly use upto 50% of head life. Hence actual effective cost of production using economical (sub-tank technology) printers are considerably higher.
  
  In our digital ink supply system the constant flow of ink is maintained as per printhead manufacturers' recommendations.

• High Production Speed : Our printer utilizes the maximum speed of printhead giving trouble free high printing speed at customers end also. Normally in sub-tank technology the high speed can be maintained for few weeks only. & in other words the high speed is only demo feature. In actual after few weeks the printhead starts clogging & drying on high speeds & later on it could not print fast even after excessive cleaning.
  
  In our system, the digital accuracy with spontaneous ink flow helps to utilize high speed printing with trouble free operations. This feature makes KVR pixojet's project more viable then any other contemporary printer.

• Scratchless Printing Quality : As defined above that the ink supply to the printhead is digital controlled, the printhead get the best possible working condition hence printing quality is also affected.

• Saving ink cost & trouble: As in digital ink supply system the feeding is proper hence excessive vacuum cleaning / purging / solvent cleaning is not required frequently. hence saving production cost & giving higher production volume.

What is Digital Ink Supply Systems :

The relevance of ink supply system, which can meet the technical parameters DOD inkjet technology with user friendly features is almost ignored in most of the printers. currently printers are using either gravity control  sub-tank technology in which the customer faces the problem of less head-life & slow speed production after few weeks, This feature makes survival of printing company in current marketing scenario.

The other -ve pressure systems with big size compressors and vacuum ejectors to maintain the vacuum are mostly not user friendly.

In view of above , after extensive research in the field of pneumatic control, we have designed, Digitally controlled ink supply. In our system, spontaneous ink flow is maintained by digital control system - the printhead receives equivalent volume of ink as ejected within fractions of second.

2. Automatic pressure purging : This ink supply system is available for -  Xaar 128, Xaar 500, printhead based printers :

The electrical purging helps the printhead to not to dry when not in printing, but due to very low pressure on the nozzles as applied by electrical actuations the printhead gets dry. & service wash is required if the clogging gets mature. hence the printhead efficiency reduces. To make  printheads back as normal, it should be cleaned with solvent & Ultra-sonic waves. which is a very time-taking process and it also adversely effect life & performance of the printhead.

The inadequate air purging through syringe is also dangerous to the printhead pores, which is used in some economical printers.

The orifice controlled automatic pressure purging is the best available technology to clean printhead in the very short time. we have used high precise & stable German components to systemize the unit.

As per our extensive study & experience - this automatic pressure purging is more effective/economical than solvent wash during start-up of the machine also.

3. Adjustable take-up :

We can provide modular & user-friendly adjustable media take-up system. Most of the printer do not use it as print does not dry till take-up point. This problem becomes more severe during high resolution, backlit or special printing. The technology of contemporary printers suggest either to increasing number of fans or by putting heavy heater, which is a expense on maintenance part & electricity ( This feature really matters when working on UPS backup during power backup).

In view of this problem experienced by printers, we have deigned adjustable take-up, whose drying path can be adjusted within quickly as per requirement of & without any extra expense. Using this feature there are no chances of print loss happens by touching / mishandling wet print.
