What is bleed? and why do i need it?
Bleed is the extension of an image or background beyond the trim edge of the paper. It is not possible to print all the way to the edge of the paper sheet.
To achieve this effect it is necessary to print a larger area than is required and then trim the paper down. Typically a designer would allow an extra 3mm of bleed to colour and image areas to allow for a little leeway when trimming.
What type of files do you accept?
We always prefer press ready PDF files, however we do accept other file types as long as the artwork is correctly prepared for commercial printing. We accept the following file types:
- Illustrator files (.ai)
- Photoshop files (.psd)
- InDesign files with all links and fonts embedded (.indd)
- EPS files
- image file formats (.bmp, .tiff, .jpeg, .psd, etc…)
What is PMS?
PMS stands for Pantone Matching System. PMS colours are standardized colours listed in the Pantone Colour Matching System. Each Pantone colour has a specific code which printers and manufacturers can refer to in order to ensure colour consistency.
What is the difference between RGB and CMYK?
RGB (stands for Red, Green, and Blue) and is the colour language of computer monitors, domestic scanners and domestic printers. CMYK (Stands for Cyan, Magenta, Yellow and Black) is the colour language of commercial printing equipment and presses.
Cyan, Magenta and Yellow are “subtractive colours” – Combine cyan, magenta and yellow on paper, and you get what perceives to be black. In practice, printing inks contain impurities that prevent them from absorbing light perfectly. They do a pretty good job with light colours, but when you add them all together, they produce a murky brown rather than black (K). In order to get strong rich dark colours, black (K) ink is added in increasing proportions, as the colour gets darker and darker thus commercial printing is done in CMYK.
If you upload files that are not CMYK (e.g. RGB) they will automatically be converted to CMYK, this can slightly change colours as they may appear different from what is seen on screen. If you are unsure please contact us to help you.
