Continuous Ink Supply System

CISS stands for Continuous Ink Supply System. As its name imply, it can continuous supply ink to the printer from external inkbottles to customized chipped cartridges (ALWAYS READING FULL).

The most direct reason is -- it offer significant cost saving to the high volume ink user and no need to buy expensive ink cartridges anymore. It means you will have fantastic saving on buying expensive cartridge. (SAVE UP TO 90%!!)
For the traditional expensive cartridge, there is always ink left in the cartridge when it read empty. By using CISS, you are not only greatly improves the utilization of the cartridge usage but also help to save our planet.

The CISS install into the printer just like the Epson cartridges. A set of tubes, come out of the cartridges and go to the bottom of the ink bottle reservoirs. The ink bottle reservoirs sit on the desktop right next to the printer, on the same level. As the printer prints and uses ink, the exact amount of ink that is used is drawn into the cartridges from the bottles. The ink level in the cartridges remains constant. The tubing is held with a bracket mounted on the printer, so there is enough slack in the tubing to allow the print head to traverse from right to left without causing any problems. In some applications the printer cover must be removed.

The system must have some air space on the top of the cartridge to prevent ink from the bottles into the printer directly. If you see any small bubbles in the ink lines, these will be absorbed by the air space in the cartridge. It is not something to be concerned about.

It is not unusual for the ink to retract as much as 6 inches from the cartridge when the printer is not being used. However, it is very common to use non-sponge design cartridge (e.g. EPSON R200/R300/Rx500/1280). Since the cartridge (bottom) hole is broken during plugging into the printer, you are no longer to use the “First Time Loading Method” to solve the air space problem. In order to force the ink back into the cartridge, you have two choices. The first one is to level up the ink container. Due to the ink potential (from high to low), the ink will go from tank back into the cartridge. The second one is using a 10ml normal syringe to extract (from bottom hole) the ink inside the cartridge until no air space on the top of cartridge. The extracted ink may be injected back to the container.

Before level up		After level up, air space disappears.

Never, Ciss is only an ink supply system. It support all ink but printer nozzle does not. Using incompatible ink or combining different density of ink causes 99% of clogging problem. For example, the maximum particle size in the pigments is 0.19 microns and the Epson print head nozzles are 25 microns plus or minus 5 microns. The ink is filtered to 0.45 microns and does not cause clogging.

When you install the CISS into the printer to replace your cartridge at the first time, please use the nozzle cleaner to clean the printer nozzle first. Since there may have original Epson™ or other compatible ink residue in the print head, a mixture of this ink and sublimation ink may clog the printer nozzle. You should clean the nozzle by using Direct Injection Nozzle Cleaning Kit in order to give the best printout performance.

An ICC profile is a file that describes the colour characteristic of any device which can create, display and manipulate the colour of a digital image. An .icc or .icm file is a set of tables that describe the mathematical values by which printers and other devices measure and describe colour. In simple terms these files translate colour information between devices. ICC profiles work the same way on both Macs and Windows operating systems.

Each and every colour device creates colour differently. Even two printers of the same model and make will require slightly different settings to produce the same colour (and will produce slightly different colours with the same settings). Also the paper used for printing has a great effect on the appearance of images and different paper weights and colour will change colours in printed images.

Custom profiles take many different factors into account including paper colour, texture (especially how it may affect liquid inks), printer settings, and more. They only way to ensure you are receiving the most accurate image fidelity possible is to use a profile what was created especially for your device, paper, inks and settings.

We offer a custom profiling service to help colour image creators get the most accurate colour possible from their devices. High-quality profiles require measurements using GretagMacbeth spectrophotometers and calculations using the best software. Our profiles give you very high quality results without the investment in equipment, training and time.

If you always use the same inks and the exact same paper, you many only require one profile. But each time you use different inks or paper, you should use a different profile. Remember that profiles are intended to “characterize” a printing process. If you change any part of that process and it has an effect on the colours produced, you need a different profile.

Top

Your profile will remain valid until something occurs that changes the way your printer produces colour. Changing the paper you use, getting a print head replacement, printer head deteriorate due to heavily use, or buying your inks from a different manufacturer are all things that could invalidate your profile an require a new one to be made. For professional printout performance, we suggest you to make your profile once per month.

RGB Vs CMYK Inkjet printers
When you print documents, your computer takes the information from your program and translates it into instructions for the printer to follow when applying colorants to paper. Some printer drivers expect CMYK data and pass that data onto the printer with minimal modification, other printer drivers expect RGB data and then internally convert the RGB data do CMYK for printing. For most purposes, knowing this information is not too important and the process is invisible to the user but when trying to characterize a device (build a profile), understanding this process is essential.
