understanding letterpress

Artwork Checklist

• Acceptable file formats include PDF, Illustrator, and InDesign (we prefer PDF)
• If you supply TIFF files they must be bitmap (minimum 300 dpi)
• Convert all type to outlines
• Bleeds should be 1/8″ (0.125″)
• Lines should be .25 point (or .003”) or thicker
• No smaller than 6 point type, 12 point or larger for reversed type
• Preserve Illustrator editing capabilities when saving PDFs
• Email any linked files along with your artwork (package your work)
• If using a halftone set line screen at 100 DPI or less

Prepping your files

Vector based artwork is best suited for letterpress. Illustrator & InDesign are ideal for creating your artwork. You can separate each color plate onto individual layers, specify your ink colors using the Pantone Solid Uncoated Swatch Library and arrange the color layers in the same order you would like the project printed.

‍

Visualizing the final print

Use the “multiply” blending mode to get an on-screen feel for how overlapping colors will appear on the final print.

‍

Using scanned artwork

Scanned artwork must be converted to line art (bitmap mode) and supplied at a minimum of 300 DPI and 100% size. Tonal variations are incompatible with letterpress printing.

‍

Using halftone images

If you are considering using a halftone they must be 100 DPI or less and are most likely not going to produce a fine print. Letterpress halftones are most successful when the a heavy dot pattern is desired.
