File Preparation — Tips and Techniques

We'd like to make the file preparation process as seamless and simple as possible, so we've put together a few suggestions we hope you'll review and follow when preparing your files:

  • An image scan with a resolution of 300 ppi (the most commonly used resolution), will begin to show signs of pixelization when enlarged more than 125%. A higher resolution can be scanned, however, if the image will be used in another project at a much larger size, possibly saving the cost of a new separation. To take full advantage of High Definition Printing™, we recommend scans with a resolution of 600 ppi.
  • For best results, always supply high-res images as CMYK EPS files. Photo CDs, digital photographs and desktop scans are RGB in their original format and should be converted.
  • When using TIFF images, avoid setting the background color to none. This should reduce problems with rasterized edges when ripping.
  • When supplying high-res images with backgrounds dropped to white, always save the path or selection as it was created in Photoshop. This can be used to create varnish masks or clipping paths, if needed.
  • Schedule permitting, request low-res files (suitable for Automatic Picture Replacement) to place in your document. This ensures that your image's cropping and sizing is accurately reproduced. This also eliminates the need for FPO scans.
  • When downloading files to disc, double check that all images, logos, fonts, etc. are included. Missing items are the most common reason for delays in production.
  • When creating documents, do not oversize the page. For example, don't create an 11" x 17" document for an 8 1/2" x 11" job. Also, don't oversize the page and create the trim marks. Why? Because these approaches eliminate the ability to use imposition software, require longer rip times, and can prevent the conversion of documents into printing spreads.
  • Always include a set of laser proofs (preferably actual size and in color) with the electronic file. It is very important to note any special instructions on them, such as items to be varnished or printed in a match color, etc.
  • Specifying vignettes in page layout programs may produce unacceptable results because of stepping or banding. Most problematic are larger and light- or pastel-colored vignettes. A good alternative is to use Adobe Photoshop® because, in Photoshop, it's unnecessary to choose a certain resolution. A 72 ppi vignette will be as smooth as a 400 ppi vignette.
  • Include all fonts used in the document. (Fonts will be used in accordance to any/all licensing agreements.) Remember to include fonts embedded in EPS files created by programs such as Adobe Illustrator® or Macromedia Freehand.®
  • When supplying Quark® EPS or Freehand® EPS files, always include the original application files, since these types of files are not editable. (Again, include any fonts that may have been used).
  • Very small point sizes, especially small serif faces reversing out of tints, should be avoided. It's wise not to knock out type smaller than 8 point or rules less than 0.6 point.
  • Before releasing transparencies or reflective artwork for separation, review carefully and note any corrections. Some color corrections can be done on the initial scan, thereby incurring no additional charges.
  • Be sure to supply working files and PDFs in case any corrections need to be made during the production process.
