Instructions – Large format printing

The most common issues with materials are due to the lack of cutting margins or fonts, as well as image resolutions not being sufficiently high.

File format
• Submit the materials in print-ready PDF format
• The supported PDF standards are 1.3 – 1.7 as well as PDF/X-1a:2001
• Disable any Security settings
• For generating PDF materials, use:
a. Printing a PostScript file and converting it using Adobe Distiller
b. Direct export from the desktop publishing or graphics editor software (Export). Only allowed with InDesign CS versions
• Make sure that the Export settings used meet the conditions specified in this document, such as in InDesign “Press Quality” or “PDF/X-1a:2001”

Image resolution
• Minimum resolution of tone images in 1:1 size 300 dpi
• Minimum resolution of monochrome images (bitmap) 600 dpi
• Minimum line thickness 0.28 pt or 0.1 mm

• Use Type1 or OpenType fonts
• Check that all of the fonts used in the job are included in the PDF file (Embedded)
• Avoid using faux italics or bolding
• Convert any fonts attached to EPS files into paths
• Colours and Overprint l Separate the materials in advance into the CMYK format
• Use Coated Fogra39 (ISO 12647:2:2004) as the characterisation profile
• Convert any spot colours into the CMYK format in advance m Convert any spot colours used (e.g. Pantone PMS) are separated into the CMYK format so that the colour equivalence is as close as possible to the original spot colour
• Transparent elements must be merged already when creating the materials
• Check the final result with Acrobat’s “Output Preview” function. In InDesign, you can review the elements to be merged by selecting the “Flattener Preview” function.
• The printer follows the Overprint settings of the document An exception to this is white text; it is opened always regardless of the Overprint settings Cutting margin
• Elements to be cut must be stretched 3 mm over the cutting edge
• Check that the cutting margin is also included in the PDF file generated from the desktop publishing application
• Cutting marks, alignment marks and colour strips may be left in the materials

Positioning • Specify the size of the publication to be the same as the final cut size of the product
• Print the pages one page at a time, not one spread at a time
• Position the materials in the middle of the sheet, with the final product and cutting margin fitting in entirely
• For a book-format product, the inner margins must be a minimum of 20 mm

Transfer of materials
