Print advertising - preparing files to send
The following guidelines apply to advertising copy supplied to Mercator Media Ltd for magazine publication
We wish to reproduce your images to the highest possible standard. When supplying scans or digital photography, we recommend that images are captured with a minimum resolution of 300dpi. These should be sent to us in jpeg or TIFF format. We cannot be held responsible for the quality of pictures that are supplied digitally.
Most computer monitors only have an effective resolution of around 72dpi. A satisfactory display on screen does not mean satisfactory magazine reproduction as more than three times this resolution is needed when lithographic printing is used.
We usually receive artwork by email if the file size doesn’t exceed 8MB. When files are too large to send view e-mail, we can download your artwork directly from a link.
Print ready PDFs should be made in CMYK (cyan, magenta, yellow and black) using PDFx1a profile. The PDFx1a profile can be found when exporting to PDF or when distilling a Postscript file using Acrobat Distiller.
The PDFx1a profile contains a series of well defined subsets that protects the integrity of the fonts and colours contained therein.
* Fonts will be properly embedded into the file
* All colour data must be greyscale, CMYK or named spot colours.
The file cannot contain RGB, LAB data.
* Encryption cannot be used.
EPS files from Illustrator are acceptable CS2-CS5 (Creative Suite 5), with text save to outlines/paths
or supply all fonts and hi-resolution Photoshop files (300dpi) usually saved in JPG, TIFF, PSD or EPS formats.
While our production department will do everything they can to ensure
that your advertising is processed as error-free as possible, we cannot
take responsibility for the colour reproduction of any PDFs containing
RGB pictures and logos.
