THE UBIQUITOUS PANTONE fan guide – the Pantone Matching System (PMS) – is an effective and proven way to communicate color intention in print. Long have graphic designers used this system to specify what they would like a color to look like. But sometimes it didn’t translate well to print as the expectation of a color match to a printed Pantone fan book wasn’t met.
Born out of a system of mixing ink (ink formulation) to create a color match, the Pantone system became the unofficial standard for printing in the US. In the ’90s, Pantone was successful in getting designers to use CMYK equivalents to select colors instead of a separate color plate on press, known as spot color, to achieve the desired color match. Confusion began when a spot color could be defined as a separate color ink or as a process color simulation (in CMYK) but listed as a fifth or sixth plate in the file.
Building upon the success of the CMYK equivalents of mixed inks, Pantone noticed the trend toward commercial sheetfed presses with six or more print towers, leading to the development of the Pantone Hexachome. Pantone Hexachome was developed to represent more than 90 percent of the original color (ink) library. Unfortunately, designers in the ’90s were still struggling to make good CMYK separations from RGB files, let alone understand how to make a CMYKOG separation. The process was complex and bleeding edge as it opened up a whole range of printable colors not possible with CMYK. There was merit for the print provider but the complexities of making a good CMYKOG separation were challenging. Pantone Hexachome was officially discontinued in 2016.
Refocusing, Pantone took stock of the common press inks available globally. This led to the Pantone GOE system. Great idea, but it never took hold in the US market. Pantone went back again to assess and realigned their printing of the beloved PMS books to conform to the current ISO print conditions. This has been a huge help in getting CMYK equivalents to be closer to what could be visual ly similar, aka G7 or a similar color appearance, by adhering to these published ISO standards.
So, in the long run, updating your Pantone books to the current edition will better align to what you are probably printing if you utilize the G7 calibration method of an ISO standard 10128:2009 and ISO 12647. The deviation from the ISO tolerances will lessen your chance of a color match to the current PMS book.
That being said, there’ s a good argument to be made that this is not realistic.
Well, your printer has a finite color range (gamut) for a given ink set, print resolution, and media. Known fact. Can’t turn it up to 11. It makes a lot of sense to print a finite amount of color patches that demonstrate what is actually printable. All common RIP platforms allow you to make a spot color reference library to print and have as a visual reference of what is achievable.
Though limited to a few hundred patches, it really helps in honing in on a color that is close enough visually to what the client would want. That sounds cool, but what if you want to create your own swatch fan books?
As we transition from Adobe, including current shippable Pantone libraries in their product packages, to a Pantone subscription-based model, there are options to consider on how to work with your clients in communicating color expectation beyond a licensed color system.
The Pantone Matching System is arguably the most ubiquitous system for communicating color and it meets the needs of today’s designers with cloud-based sharing of color palettes among colleagues and suppliers. Pantone’s ColorCert program enables print service providers to put a QA program in place to meet the tolerances needed to achieve an effective color match to the current Pantone Matching System, PMS.
