Ink Cartridges

Basic Colours Explained – Why Black is K



The black colour can be defined as the absence of all other colours, as compared to white, which is a combination of all colours. The science behind the colour of black lies in the types of colour which are reflected back. Black is the absorption of all of the colours, with no colours reflected back to the human eye. Comparitively, white will reflect the entire colour spectrum back to the human eye, which then recombines them into the colour that we see and recognise as white.

Black can be printed by combining 100% of the Cyan, Magenta and Yellow colours (making a separate black cartridge redundant). However, this method has its drawbacks as often the colour produced is closer to grey than a true black. The benefits of a separate black cartridge also lie in its ability to be swapped out without wasting left-over ink from the other colours in that cartridge, as black ink is the predominant form of ink used.

To produce better results the four colour printing method CMYK is used where black is K and the fourth cartridge colour. This stands for Cyan, Magenta, Yellow and Black. K is used instead of B in this method to avoid confusion with the Red, Green, Blue (RGB) acronym where B is blue. The K used instead is derived from the German word ‘kohl’, meaning coal.


Cyan is also called process blue and is one of the subtractive primary colours used in the CMYK or CMY colour methods (where CMY is just CMYK where black is derived from mixing the three colours, as explained above). This colour is primarily blue, with some green in it.

For printers using ink cartridges Cyan is either inserted as one of four cartridges (one for each of the Cyan, Magenta, Yellow and Black) or as a combined ink cartridge with Yellow and Magenta.


Magenta is also called process red and is the second of three subtractive primary colours used in the CMYK and CMY methods. The magenta colour is greenless, meaning it absorbs all wavelengths of green light and predominantly red with a tinge of blue.

Like Cyan, Magenta is either inserted as one of four cartridges (one for each of the Cyan, Magenta, Yellow and Black) or as a combined ink cartridge with Yellow and Cyan.


Yellow is the third and final subtractive primary colour used in the CMY and CMYK printing methods. Yellow is blueless, meaning that it absorbs all wavelengths of blue light.

Like the two other subtractive primary colours, Yellow is either inserted as one of four cartridges (one for each of the Cyan, Magenta, Yellow and Black) or as a combined ink cartridge with Cyan and Magenta.




Cheaper Laser Printers Have the Most Expensive Printer Cartridges

A few years back small to medium sized businesses preferred laser printer cartridges more than ink cartridges. Today the gap is becoming closer because there are many different choices available on the market and the prices of printers are becoming cheaper.

Before buying a cheap laser printer, you should calculate its ongoing costs. In most situations, you would end up paying a lot more because the refills are typically expensive. Manufacturing companies have been hiding the truth about the real cost of producing their laser printers. In reality, the cost of one unit of laser printer is not that cheap, but these companies belief that they will profit more on the sales of cartridges. Selling the printing devices with a dicey deal is just their marketing strategy to get more profits in the long term.

Many people are now aware that the cheaper a printing device is, the more expensive its refills would be. A leading brand like Hewlett Packard has reaped around $15 billion in profit from the sales of printer cartridges alone. This is because most businesses do a lot of printing on a daily basis so basically they will keep buying new cartridges.

Ink cartridges are relatively cheaper than the laser ones. Their printing capacity differs from one brand to the next. Overall, it’s up to you to decide but keep in mind that cheap laser printers are likely to have expensive cartridges.

Australia Post Celebrates National Recycling Week By Repurposing Printer Cartridges As Pens

Australian parcel service Australia Post goes through a lot of ink cartridges, printing shipping labels and work orders for packages across the nation. But this year, the company hoped to make more from printer cartridges than a few extra deliveries. To celebrate National Recycling Week, Australia Post partnered with environmental non-profit Planet Ark to recycle used ink cartridges into pens.

The Enviroliner felt tip pen is made from more than 95 per cent of recycled plastics and inks, with one cartridge making two pens. Each person who donated a printer cartridge to the cause got to take the pens home as souvenirs, giving the ink and plastic new life.

Project organizers released a statement, saying the project was designed to combat e-waste; the disposal of technology items that may contain harmful chemicals and can harm the groundwater around landfills. Mobile phones, computers, tube televisions and printer ink can all add toxins like mercury and lead to the environment if not disposed of properly. Planet Ark’s campaign manager Brad Gray stated that one third of people still throw printer cartridges in their home trash.

“By making e-waste recycling so accessible Australia Post is helping to encourage more and more people to get involved,” said Mr. Gray.

Beyond just pens, printer and toner cartridges collected by the program will be used in a variety of ways. Some will be returned to their original manufacturers so they can be refilled and parts can be repurposed. The remaining cartridges will be converted into new products such as pens, park benches and rulers.

HP Takes Digital Printing Innovations On The Road In The UK

With a cadre of new innovations and a rock-star-style tour bus, printer ink and technology retailer HP is hitting the road, bringing printer and printer cartridge demos to destinations across the UK.

According to a statement released by HP this week, its branded truck will make eight stops between November 15th and December 2nd to showcase faster printers, more graphics capabilities and simpler HP ink cartridges.

HP will kick-off the roadshow at Sandown Park, in Esher, hitting London and Manchester along the way. The tour will also stop in Scotland; hitting the Midlands and Edinburgh. The tour concludes in Ireland with stops in Belfast and Dublin and, like true rockstars of the printing world, the tour finishes with a stadium: Curvaheen Park Stadium in Cork.

With a host of new innovations to introduce to its customers, the tradeshow will focus on recent speed upgrades for HPs T200 Inkjet Web Press, as well as the clearer graphics offered by new ink cartridges and delivery systems, introduced at tradeshows throughout this year. HP believes the faster, more efficient printers can help businesses increase profits and fill more orders, keeping up with the faster pace of commerce.

“As the graphics market shifts from analogue to digital printing, we are helping print service providers grow their businesses with new capabilities, enabling them to expand into new application areas and improve delivery times for high-volume digital printing,” Jan Riecher, vice president and general manger in graphic solutions business at HP, said Friday.

Photo printing and image management with your printer

Photo printing, as pro photographers know, is a potential minefield of quality issues. The technical side of printing needs some attention to detail.

You can also get very good deals on ink cartridges and laser toner for photo printing in Australia to cut down on the cost of your prints.

Setup and data issues

Depending on your camera and your printer software, you’ll need to get your photos set up for high quality. The trouble is that some photo software has its own ideas about quality. Older printers can’t always work with new software, either, another common problem. The name brand cameras are usually OK for all printers, but the proof is in the print, and that’s where the issues usually start.
