Just what is 5% coverage?

5 percent page yield ISO standard

Kenyans - In printing terms - just what is a 5% coverage

I often hear that customers can’t believe their ink or toner cartridge is empty. Yet, when I check them, they are in fact empty. I know the perception is that cartridges don’t last as long as they should. That is because of the page count on the box! These numbers really don’t mean much to the average user and don’t reflect the reality based on what people normally print.

The reality is that all page yields are based on 5% coverage of ink or toner. This is a mandate from Organization for Standardization (ISO). Most people regularly print more than the 5% average.

5% represents a small invoice or memo (covering around half the page) and not a full page of larger text with logos and other print. For example this newsletter will end up representing more like 10%-12% coverage if it was printed out.

So your actual page yield will most likely be less than the advertised yield, no matter where you buy the cartridge-as everyone’s yields are all based on only 5% coverage- everyone has to place the same amount of ink or toner in cartridges. Starter cartridges that come with new printers often have half or less toner or ink in them than a normal cartridge. In fact, we fill some ink cartridges with more ink than the originals had in them.

Over the years, I have performed enough research and development to find these facts to be true on several of the same cartridges from different vendors, including our own products, against the OEM (name brand cartridge). Using our compatible toners will make sure that all you do is save lots of money with products from ColourSoft!

The above is what 5% coverage on a page looks like according to the ISO 19752 document. If a toner states that it prints 2,000 pages, it should technically be able to print 2000 pages of the above. We at ColourSoft, aim to do this with every toner we sell.


Say for example, a toner states that it prints 2000 pages @ 5% coverage, if one was to print the above type of document which is FULLY BLACK indicating a 100% coverage, the toner would run out after 100 pages!


So it’s important to know that depending on what type of documents you print, the page yield will depend on the coverage of the toner. Bold text and images take a lot of toner for example, so you will probably get less pages at that type of coverage.
