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.

Preparing files to send
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.
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.
Trim area, Type area, Bleed explained
Ads should only ever be delivered to exact dimensions of bleed or type size, never to trim.
- Trim area is for information only and represents the physical size of the finished product after bleed has been removed during printing. Adverts that ‘bleed’ off the page will be trimmed to this size. Ads should only ever be delivered to bleed or type size, never to trim.
- Type area (also called Live area) is the area within the trim area where the type (or live information - text and images) should be contained. This ensures all vital information is visible to the reader.
- Bleed is an area 3mm larger than the trim size on all four sides and is required when adverts have pictures or colours going right to the edge of the page. So, for full colour adverts, please supply to the exact dimensions of bleed size. If you don't want to have bleed on your ad it should be supplied to the exact type area size.
Our site incorporates ‘responsive’ designs. It can detect the device on which it is being displayed, whether desktop PC, tablet or mobile, and render with the size, layout and resolution that makes it easiest-to-read.
