Our top five help topics
- What is bleed?
-
Bleed is the portion of your artwork file at the very edge that extends beyond the trim lines. The bleed area will be cut off in the printing process.
When having something professionally printed, multiple pages are printed on one larger sheet of paper, and then that printed paper is trimmed into individual page spreads (or brochures, or posters, etc.). When your artwork spans the entire size of your page, if you don’t have a bit extra that you expect to be cut off (the bleed), you might end up with a white edge appearing on the trim line of the finished piece.
It's important that any backgrounds or images that touch the edge of the printed piece 'bleed' outside of the trim line to make sure that when it's trimmed after print there is no risk of a white edge appearing on the finished piece.
We advise 0.125" bleed on all artwork.
- Which file types can I upload?
-
We prefer a single PDF file made up of multiple pages, but we like to be as flexible as possible, which is why you can upload your files with us as single or multi-page PDF, JPG, PNG, Postscript, MS Word, Publisher, PowerPoint, Lotus or Excel file.
For the best results, make sure that your colours are in CMYK and that your images that are between 150 – 300dpi (dots per inch).
- How do I upload my covers and spine design?
-
You can either upload them as three separate documents--front cover, back cover, and spine--or as a single spread. Please see our Spine width calculation when you add an order to your basket.
- Should I upload single pages or spreads?
-
Our system accepts both single pages and multi-page spreads. If you have any issues, please get in touch and our team will be able to help.
- Where do you deliver?
-
Select a destination in your Cart to get your delivery cost. By default, Mixam provides delivery costs country-by-country, but we can also ship prints worldwide on request and even provide split shipping on sufficiently sized orders.
