Move proposal[edit]
As far as I can find, CcMmYK is not a "color model". I'd say we should move the article to something like "CcMmYK printing", since the use of these six inks is stricting a printing hack. Any objections or alternative ideas? Dicklyon 05:37, 10 August 2007 (UTC)
This is not a color model. At most it is a variation on the CMYK color space, but is generally not used to encode color values independently from the printing process. Color is not generally communicated in or stored in this configuration and no image formats deal with color in this format. Color profiles built for these types of printers use a CMYK color mode. This is one of many ink configurations that are common to inkjet printers. Other version add additional "gray" inks or may add green or orange inks. Perhaps this could be added to the inkjet article since this print configuration is most commonly associated with various inkjet printers. --Hueman79 (talk) 18:52, 20 June 2015 (UTC)

This is not necessary[edit]
I argue that this is a scam by the printer manufacturers, as it's no secret that most inkjet printer manufacturers make an unreasonable profit off of their inks, and go to great lengths to protect this scam. (define: scam) ref: https://www.yoyoink.com/articles/why-is-printer-ink-expensive/
As mentioned above, this is done to make a smoother print result, which is also achieved by using a higher resolution printer. We know printer dpi has evolved over the years, and I have a hunch that at the time when these half colors came out, so did a jump in printer dpi, so this would seem like a good thing to anyone wanting to print a less grainy print as this would be compared to a lesser dpi printer - which happens to use only CMYK.
Why is this a scam?
1) It goes without saying that selling 6 ink carriages is more profitable than selling 4, at the same price per cartridge. 2) What's even better than that is to have returning sales for 6 ink cartridges instead of 4. 3) It is not necessary to worry about visible halftones at any resolution higher than 1200dpi as they will not be significantly visible to the naked eye. I am even leaning more towards stating 600dpi for this arguement, but I will state 1200dpi to remove any reasonable doubt. 4) Printer manufactuers do not discount the half color inks by the amount that they have been diluted. That's all these inks are, diluted CM inks, and if they are solvent based inks, they can be diluted with a solvent, and the cost of the raw solvant should be indignifficant on the ml scale of these liquids.
Definition of scam (Entry 2 of 2) transitive verb
1: to deceive and defraud (someone) … the law firm had got the lucrative job of defending the corporate head of a savings and loan that had scammed another thousand or so people out of their savings … — Joseph Wambaugh 2: to obtain (something, such as money) by a scam A Boston hedge fund manager who scammed millions of dollars from friends, family and other investors in what authorities say was a Ponzi scheme has been sent to prison for more than 14 years. — The Worcester (Massachusetts) Telegram & Gazette (https://www.merriam-webster.com/dictionary/scam)
Conclusion: Buying a higher resolution printer, that prints only CMYK makes more sense to eliminate any visible "halftones" and will save the consumer a lot of money in the long and short term.
Consumers need to be made aware of this scam, and rather opt for a finer resolution printer.
Printer DPI Is Dots Per Inch Printers print by applying ink or toner onto the paper. Inkjets use nozzles that spray tiny drops of ink, while laser printers melt dots of toner against the paper. When more dots are squeezed into a square inch, the resulting image is sharper. A 600 dpi printer squeezes 600 dots horizontally and 600 dots vertically in every square inch of the sheet. Some inkjet printers have a higher resolution in one direction, so you might also see a resolution like 600 by 1200 dpi. Up to a point, the higher the resolution, the crisper the image on the sheet.

What's Good Enough? For a letter or business document with graphics, 300 dpi will look fine. If it's a handout for the board of directors, 600 dpi does the trick. For the average photographer, 1200 dpi is excellent. These specs are within reach of most printers on the market. When a printer prints above 1200 dpi, it's nearly impossible to see any difference in the prints.
There are exceptions. Professional photographers who want a higher resolution should look at 2880 by 1440 dpi or higher. ((https://www.lifewire.com/dpi-ppi-print-quality-settings-2769170))
