Previously, when a PMS color was output without using spot inks, the computer would read the CMYK definition provided within the PMS color library and output the color using those values. It is very common for proofs to be printed as CMYK builds, or designers use Pantone colors when they never intend to print with spot ink. If a printer is printing with spot color, no problems will arise. Lab Definitions are used to produce the color on-screen.īecause Pantone solid colors are intended to be used only as spot ink, Pantone had decided to drop the CMYK definitions and only provide only Lab definitions. This definition provides the printer the CMYK values that most closely match the PMS color. This change has been the most problematic.īefore Pantone Plus Series, PMS colors contained two definitions: Lab and CMYK.ĬMYK definitions are used when PMS colors are printed without actually using the spot ink intended. Pantone dropped the CMYK color definitions for their Spot Coated and Spot Uncoated color libraries.In an effort to make on-screen display accurately represent ink colors, Pantone has changed the Lab definitions of their Spot Coated and Spot Uncoated colors.Because there were slight variances between the two, you may notice some colors you’ve previously used being slightly different. With the addition of the new Pantone Plus Series, Pantone combined them into one universal set.

Pantone previously had two sets of Color Bridge libraries one for the United States, and one for the rest of the world.

Three big changes were made during the creation of the Plus Series: The new Pantone Plus Series (PPS) has created a major issue with shifts in color, resulting in inconsistencies between color in old documents and ones created with the new libraries.

A major difference between Adobe CS5 and CS6 is the update in color libraries provided by Pantone.
