Post printing provides an opportunity to print in an offline process. This process doesn’t afford the same opportunity for color, clarity, consistency of position or complexity of artwork. Due to the limitations of the offline process the expectations need to be understood prior to placing an order as there will be no returns accepted relative to the listed items. WCI will do its best to provide a quality product as close to our inline printing capabilities, however with the understanding it may not able to achieve the above parameters with the offline process.

Due to the nature of waterbased ink, colors will change when printed on colored paper. Therefore, if WCI is required to match a Pantone color on colored paper (regardless of PMS number) a special match charge will be added.

Art Charges: Any additions, deletions or changes to artwork will be charged at cost. An estimate will be provided, and must be approved before any art changes will be made.

Plate Charges: $150.00 per color per art size. Includes art processing, film prep and plate charges. Cost dependant on camera or digital ready artwork provided to WCI specifications. Art and plate estimates are available from customer service. Estimates subject to review of actual art supplied by customer.

Registration Tolerance & Trap: Wherever two colors meet, a 4.5 point trap – 1/16″ – is required to trap the colors. Where two colors are adjacent and the designer does not want them to touch, there should be a minimum of 1/4″ of space between the two colors. As a general rule this register tolerance precludes the use of two overprinting colors to create a third color, whether with solids or screens; and when attempted would need a third color such as black to outline the shape. Note that due to our production process, there is no trapping or overprinting on Claycoated paper.

Line Width & Type Size: Minimum positive printing line width is two (2) point. The minimum reverse printing line width is (3) point. Minimum positive printing type size is ten (10) point. The minimum reverse printing type size is twelve (12) point bold. These guidelines are subject to review with serif type faces, and with designs including heavy areas of broad solid along with small type in the same color. In these circumstances the type may need to be larger and/or bolder.

Screens & Halftones: The line screen rulings used in our process are 45 to 55 line. The coarse screen is not apparent and insures cleanest possible dot reproduction. Due to the differences between how wide web flexo and offset litho reproduce screens and halftones, we request the opportunity to review the design elements to provide specific production art direction as early in the planning process as possible. Halftones must have strong contrast, as must steps between manually selected screen values of the same color. Subtle tone variations will not reproduce.
