Why Sponge Free Cartridge?
Last Updated: 01/18/2012

Sponge Free Cartridge - The New Standard

Most consumers are wondering why should we use a sponge free cartridge for Canon / Epson Printers? Why can’t we just use the same sponge cartridge for edible ink?

The entire printer manufacturing industry, "Epson", "HP" & "Canon”, designed the ink cartridge for normal document/photo printing purposes. Their cartridges are not meant to be used for the food industry, particularly the edible image market. Most of the edible ink companies on the market just replicate the OEM cartridge design or even use their recycled product in the food industry which is very irresponsible. As we all know; with moisture and at room temperature, the sponge will easily grow molds, yeast, and bacteria. In most of the case, these harmful microscopic particles can’t be seen by the naked eye. However, they will be printed on the cake, cupcake, or cookie and consumed by your loved ones or sold to your customers. This will make the edible image no longer a pleasant experience, if you know what’s inside. If you want to know more details about "Bacteria in Sponges" just type "Bacteria in Sponges" in a major search engine such as Google, Yahoo, MSN, or Bing.

Safety and sanitation are our first concerns. By using 100% SPONGELESS DESIGN CARTRIDGES for edible ink, consumers can reduce chemical reactions, prevent bacterial growth, keep ink color vivid, and insure ink stability for a long shelf life.

What So Unique About Spongeless Edible Ink Cartridge?

By using our new spongeless cartridge do require higher standard on the ink. Our edible ink already been purified and filtering during ink-making process in US facility and we are using the most advance filtering system to keep low volatility for keep nozzles from clogging print head.

We only use 100% brand new raw materials and we do not mix with any recycle plastic in our products. So you can see our ink tank is clean and clear not blur. The best part is - empty space for filling more ink. Extra ink is a added value of this new design, the most important is: all the ink in the spongless cartridge are 100% useable, which means “all the ink you can see, all the ink you can use.” – till the last drip of it. Unlike traditional cartridge with sponge that the sponge part already holds up significant amount of ink, you can see them but can not drain them out of the sponge and use it. You either need to refill them or buy a new set. Which is a big waste consider the price that you paid for the ink.

What Is The Role Of  A Sponge In A Cartridge? Is It For Filtering Purposes?

No, the sponge is not for filtering purposes.

The main role of the sponge in a cartridge is to keep the pressure balanced and prevent ink from leaking out of the ink tank. It does not offer a filtering feature. If done properly, the ink supplier should pre-filter their ink before selling it on the market. It is a very weak product feature to count on the sponge to do work it isn’t even supposed to do; your supplier should use a filtering system to clean the ink. It should not depend on the sponge to filter it.

If you been refilling Canon sponge cartridges a few times then you will find out the sponge cartridges begin to leak ink. It is because over time the sponge will begin to shrink in the ink tank and more ink can travel through it. Sponge can’t hold that much ink at all and will cause the pressure balance to be lost. Sponge cartridge are not designed for edible ink because it is so easy to contaminate with bacteria and many other germs hiding inside the sponge.

Will using spongeless cartridges clog my printer head more easily?


All brands of inkjet printers will clog if you don’t use the printer for a period of time.  The reason is ink dries on the print head itself and causes clogging.

If your vendor has told you that sponge cartridges can filter the edible ink, ask your vendor if he can guarantee that sponge cartridges will prevent clogging ink in the print head. In other words, is he saying the printer will no longer clog if you use a cartridge that has sponge? Also ask your vendor if sponge is safe to use for edible ink. Please have him put it down in writing like our company does to protect your safety.
