“Repeatability and cross-platform colour delivery are now critical commercial pressures for printers, and guaranteeing each across different substrates, gamut and chemistries is mission-critical,” explains Frederic Soulier, chief technical officer, Caldera. “Whether customers are demanding conformity with the major ISO, Fogra, or G7 standards, this addition to the Caldera EasyMedia module will keep them consistent and competitive.”
G7 is a definition of the appearance of greyscale and a methodology for applying this to CMYK-based print machinery. The device-independent process uses a neutral print density curve to create faithful comparisons and enable shared appearance of output when cross-process colour management is unavailable. Caldera’s implementation is anticipated to be particularly popular in the North American market, where IDEAlliance’s standards are widely adopted, and features compatibility with G7 Greyscale, GRACoL, SWOP3, and SWOP5, which define characteristics across different types of substrate.
Caldera simplifies the complex process of hitting these standards by handling conformity calculations within EasyMedia in the RIP suite. Operators select a print configuration in Print Standard Verifier and confirm the standards their output must meet, as well as the targets the colors are expected to hit. The Caldera engine then measures print colors against the required chart to verify if the print settings will enable meeting the color standard requirements.
“Universal standardization has existed in offset for some time, but the variables incumbent to digital print have made it difficult to establish a global standard,” explains Joseph Mergui, chief executive officer, Caldera. “However, print buyers expect homogeneity of color regardless of application and substrate, be it signage, packaging or paper. Our continuous upgrades to the Caldera suite are driven by these pressures and keep our printers at the leading edge of dependable, color-faithful production.”
The IDEAlliance G7 protocols join a number of other specific international standards within Print Standard Verifier. ISO 12647-2 for offset litho, 12647-7 for proofing from digital data and 12647-8 for validation processes from digital data are all included, as are Fogra’s Process Standard Offset and Process Standard Digital. RIP owners can receive the addition of G7 to the suite with purchase of a software update.
