Artwork Requirements

The Graphic Arts Center processes artwork on IBM computers running Windows operating system. GAC accepts art created in PC and Macintosh computers only in specific applications which allow cross-platform conversion (please see listing below).

Please specify authoring platform when submitting art to ensure accuracy. Conversion of files not meeting these software requirements are subject to additional charges for production. Spectrum adheres to the standard industry definition of reproducible art and reserves the right to accept or reject art depending upon the job. Vector art is preferred for spot color printing. Supported native file formats are:

Files from other software should be saved in EPS or PDF format and all type in each file should be converted to curves (paths, outlines). JPEG and TIFF files can be acceptable only if sent in high resolution. Submitted artwork that requires reworking for production will incur an art charge (most jobs require some amount of work by the Graphics Dept. to setup for production).

We typically cannot accept ads created in the following software: Microsoft Publisher, Microsoft PowerPoint or Microsoft Word. Adobe PageMaker, Quark XPress and FreeHand users – files must be exported to Adobe Illustrator (.ai) or EPS format and ALL TEXT/FONTS CONVERTED TO PATHS/CURVES/OUTLINES.

Resolution for Art of Photographs

All files should be built at 100% output size and sent ready to open. Avoid file compressions such as LZW and JPEG routines which cause damage to the original production file. All scanned images should be no less than 300dpi RGB color space. For grayscale and monochrome black & white line art, ideal resolution is 600dpi. Scans that do not meet resolution specifications are not guaranteed to output well and submitting agency assumes responsibility. If you require scanning, please provide color or black and white photographs not less than 5×7 inches displaying good focus and properly composed. Art and photos downloaded from the Web must meet the above requirements for optimum output. Photos downloaded from Web pages that have been saved at low resolution (72-100dpi) may not print clearly.

Do not include halftone images such as those used in magazines and newspapers. Pre-press output for screen printing is widely divergent from traditional angles and screens used for offset printing and lithography. Our standard line screen output is 35lpi which yields an average tonal range between 25% – 75% density.
