FLEXO Magazine : July 2011
to make all small type and strokes one of the base colors used in separating. The human eye perceives color shifts more easily in large, flat areas of color than in patterned or textured areas. For this reason, the most effective expanded gamut jobs contain many different patterns or textured elements (checkerboards, stripes, rays, images, gradations, etc.), rather than flat color that, when refined, will separate into color overprints. Due to a number of different press complexities in flexography, these colors could vary across or around the web and show undesirable color shifts. Designers and CPCs may resist expanded gamut initially because the systems cannot replicate perfect matches to established color systems like Pantone. There are too many factors in play that affect color reproduction: registration, substrate, printing sequence, lamination, etc. As a prepress provider and printer, you should provide a solution that makes color prediction easier for the designer and CPC. Create swatch books of the different Pantone PMS and GOE colors processed through the expanded gamut system, and have these available to send to customers that want to implement this system. Designers can then pick from these books when selecting colors. CONCLUSIONS Remember that communication between the printer, the prepress provider, the designer and the CPC is critical in or- der to successfully process work without error and consistent- ly across a family of jobs. Before beginning any new project, the printer and prepress provider should ask themselves the following questions: • Do the designer and the CPC have a basic understand- ing of flexography? If not, do I have information available 32 FLEXO july 2011 www.flexography.org ReSpONSIbILIty As packaging graphics continue to increase in complexity and production timelines continue to compress, the clear assignment of responsibilities is necessary to ensure a quality printed product in a timely manner. The assignment of responsibilities requires planning and collaboration among all involved parties. • Consumer Product Company (CPC): Ultimately, the customer defines expectations and therefore, must drive the collaboration process. The customer determines the effort expended to reach satisfaction. The CPC must facilitate communication between the supply chain parties: designer, prepress provider and printer. • Designer / Production Design: The designer must work with both the prepress provider and the printer to under- stand the capability of the printing/converting process being utilized. Based upon the print capability, the designer must provide a design concept that will enable the printer to meet the expectations of the customer (CPC). The earlier in the design development process the prepress provider and printer are involved, the better able the team is to determine specific capabilities and ensure the final product meets the customer’s design objectives. Additionally, the designer is responsible for: Establishing a basic color scheme and color palette before final files are sent to production. Checking all copy for spelling and kerning. Treating common elements and logos consistently in the layout. Building all copy and vector-based elements in accordance with the specifications of the print provider. • Prepress Provider: The prepress provider must work with the printer to understand the capability of the printing/ converting process being utilized. The prepress provider supplies the designer with accurate and timely informa- tion regarding print capabilities at the beginning of the design phase to facilitate the creation of a printable design. Based upon the print capability, the prepress provider produces appropriate films/files/plates that will enable the printer to meet the expectations of the customer (CPC). They must document the controls that ensure the consistency and accuracy of the supplied media (films/files/ plates). Additionally, the prepress provider produces a contract proof calibrated to accurately predict the printed result. The prepress provider must provide the printer the ability to objectively confirm the accuracy of the prepress work and the printing process. This can be accomplished through the use of agreed- upon control targets. • Printer: The printer is responsible for consistently reproducing the graphic design to the satisfaction of the customer (CPC). They utilize and document the process controls necessary to ensure that accuracy and consistency are achieved. They work with the other parties and suppliers to define the capa- bility of the printing process. The printer provides the designer with accurate and timely information regarding process capabilities at the beginning of the design phase to facilitate the creation of a printable design.
