- SOFTWARE – Make sure the software you are using is the same kind your printer is using.
- IMAGES – Convert image files from RGB to CMYK before placing in page layout or sending to the printer.
- FONTS – Use Postscript or Open Type fonts (True Type fonts do NOT work).
- IMAGE RESOLUTION – 300 dpi images at final size is good for most applications. Scan line at 1270 dpi for nice clean edges.
- SPOT COLORS – Specify any PMS colors used in your documentation.
- BLEED and CROP MARKS – Include 1/8″ bleed and offset crop marks 1/4″ so they do not touch your image.
- TRAPPING – Leave that to the printer. Printers use much more sophisticated software.
- PREFLIGHT – Use preflight software to check your files for fonts, images, colors, etc. Missing items will be listed in the summary. Print separation proofs, especially for jobs that are process plus PMS.
- PRINTER PROOFS – Be aware that printer proofs are a very good guide but not 100% of what you will see on press. A printer proof match on a coated stock is relatively easy. You may experience some subtle color and/or density differences on an uncoated sheet, as a result of courser line screens and more absorbent paper.
