What are "print ready" PDF files?
Print ready PDFs (Portable Document Format) are the preferred format for "open and print" projects. Because these files are created with all resources necessary to achieve final printing without any modifications, there are no setup fees involved. Files sent to us that are not print ready PDFs, or that require color correction, and/or multiple proofing cycles are subject to a one-time setup fee of $55.

What if my files need color correction?
Color corrections and substitutions can be made during the production process, but there are limitations. Pantone color matching applies only to vector art contained within the files provided to us. Raster (i.e., pixels or bitmap) images can be altered in a global sense (overall tones, contrast, etc.), but not with the same precision that can be made with vector graphics. Please don't hesitate to contact us if you have questions regarding the ideal parameters required for quality results.

CMYK or RGB?
CMYK is preferred. Image quality may be affected if RGB is used. If a PDF is submitted the file MUST BE set up in a CYMK workspace. If your file contains transparency (drop shadows, overlays, etc.), gradients or blends that affect spot colors, they should be converted to process (CMYK) builds before printing.

What computer platforms does PosterPrints support?
ALL MACINTOSH, some PC/Windows applications.

What software applications does PosterPrints support?
ALL MAC: QuarkXpress, Macromedia Freehand, Adobe Photoshop, Adobe Illustrator, Adobe Pagemaker, Adobe InDesign. Some PC/Windows. All of the above listed for PC, Corel Draw. Call for others.

Compression?
If possible, NO compression (jpeg, LZW, gif, pict, or any other) should be used. Image quality may be affected if compression is used.

What ppi should be used?
150 pixels per inch AT FINAL OUTPUT DIMENSIONS is required for best results, i.e., in Photoshop, under image >image size >150ppi at 24x36 (for a 24x36 poster). Image quality will be affected if resampling is used.

Should placement and color proofs be submitted with files?
ABSOLUTELY. If not, a waiver must be signed.

Fonts?
ALL fonts (screen and postscript) must be included with layout file. If the application allows (Freehand, Illustrator, Corel Draw) convert all fonts to paths/outlines.

At what widths can the output be produced?
Up to 96" wide image area for banners, vinyl, paper and some fabrics. Up to 58" wide for most other products.

At what lengths can the output be produced?
400 feet (usually in 50-75 ft sections)

How close will PosterPrints output match the supplied color proof?
About 70-80% of all spot PMS colors (vector) can be closely matched. Realistic color is achieved on all Photographic (raster).images. If colors MUST match exactly, please call to discuss options. You will be supplied with color proofs of your output as time allows.

We accept zip, jaz, cd or ftp transfer.
