Window Envelope file supply guidelines
Bleed and Quiet Zone
Window Envelopes have specific templates for you to use. These are pre-designed in C4, C5 and DL sizes and they all have areas that cannot be printed in, these are called the Clear Zones. Please check the relevant template to view the printable areas.
C4 Window Envelopes cannot have elements bleeding to the page edge. Bleed is allowed on the C5 and DL sizes, see the finishing note section further down this article.
When you save your PDF ensure that you save it at the same size as the template. Please note that no crop or registration marks are required.
Colour & Ink Coverage
Please set your vector and bitmap artwork in CMYK colour. All files must be supplied in CMYK. RGB, Pantones, Duotones and other colour spaces are not supported and will be converted to CMYK, this could cause a colour shift so we recommend that the conversion to CMYK is done prior to upload.
Ink levels must be set to a maximum of 300% total ink. Exceeding 300% may result in your job being set to status 091 and delayed.
The minimum tint level is 10% per CMYK channel and tints over 90% will tend to look 100% when printed.
Remember to choose the correct single or double sided product code to match your design requirements.
Ink Coverage
The standard envelopes are printed with an expected ink coverage up to 60% of the printable area. Full canvas artwork above 60% coverage will be rejected.
Large Areas Of Solid Colour
We would advise to avoid using large areas of solid colour. Tinted areas of more than 60% tint may cause dot gain.
Fonts
Your PDF file must have all fonts converted to outlines. We recommend keeping all text above 6pt size. Note that the minimum stroke width is 0.5mm so ensure that any text elements aren't thinner than this.
Images
If you are using bitmap based artwork then ensure your files have a resolution of at least 300 dpi. TIF, JPEG and PNG images are supported within your PDF. Images must be CMYK.
Bitmap files should be flattened and not contain any layers.
Borders
Avoid using borders as they will look uneven when printed. Do not add stroke borders to your design.
Reproduction of details
The minimum stroke thickness is 0.5 pt for positive strokes and 1 pt for negative stokes (when a line is punched out of another coloured object).
FileCheck
FileCheck (status 021 in Flyerlink®) does not support the range of Envelope products.
Template Layers
The Illustrator based templates have 2 layers.
The top layer is where you add your logo or artwork as a vector or bitmap files.
The bottom layer contains guidelines on using the template. This layer must be turned off prior to saving your PDF file.
Saving your PDF
When saving your PDF ensure that the guidelines layer is deleted or made invisible. Save your PDF as a press ready PDF using version 1.4 onwards.
