Trapping

All trapping will be completed during the RIP process before going to press, and will be the responsibility of Communication Arts. We have found that this is the best, most consistent way to handle this issue. If your ad has special trapping requirements, please contact us directly at production@commarts.com and we will work to accomodate your request.

Proofs

Every ad must be accompanied with a professional quality proof (necessary for an accurate representation of what will happen on press). Formats such as ink jets and dye subs do NOT give accurate color representation and are not acceptable. The recommended output formats for proofs are listed below and can be found at most professional service bureaus.
