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: Maximum cost $125.00 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.

Any charges necessary to produce your order will be indicated on the "Proof of Art" form, as proof approvals are required before order can be produced. Print name must be provided prior to order acceptance.

Proofs & Ink Drawdowns: We send proofs on all orders with new or revised art. We send ink drawdowns on White Kraft and PMSC Claycoated only when requested on P.O., or when there are traps and/or overprints on White Kraft that in our judgment should be approved prior to production. We send drawdowns on all PMSU matches on Natural Kraft and Oatmeal, as well as all custom matches.

Proof Approval Form: A proof approval form must be signed and returned before any production can begin. No credits or returns will be allowed for any element in accordance with the approved proofs and/or approval form. Order Confirmation: We send Order Confirmations for all orders. Signed approval and fax back is required before any production process starts.

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 4.5 points 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. Maximum Photoshop resolution needed is 125. 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.

Custom Ink Match: We can custom match submitted materials, or use PMS color specifications. When using PMS, specify colors from the Uncoated "U" section of the book or Coated "C" section of the book as appropriate. PMS ink color standards and formulations are per our ink supplier's current PMS swatch book. If we are printing a PMS color on uncoated paper that has been reproduced on coated paper previously, we suggest the end user and/or artist specify a PMSU shade that best matches the coated paper version when submitting the art and order. We print on Natural Kraft, White Kraft, Oatmeal and Claycoated papers. All inks are water based. No metallics on Claycoated. We send ink drawdowns for PMS colors on White Kraft and Claycoated only when requested on P.O., or when there are traps and/or overprints that in our judgment should be approved prior to production. Note that due to our production process, there is no trapping or overprinting on Claycoated paper. We send ink drawdowns for PMSU matches on Natural Kraft and Oatmeal, as well as for all custom matches to colors other than PMS numbers. Approval is required before bags can be produced.

• Metallic inks are only available on NK, WK and Oatmeal papers - not on Claycoated.
• Metallic Silver and Gold are available up to 50% ink coverage. We offer one shade of Silver and one shade of Gold.
